Okay, here is my problem: Every once in a while I will completely lose all signal on my phone. It wont pick up 2G, 4G, nothing. Wifi and bluetooth both seem to work though just fine. I've searched and haven't found anyone with the same issues so I'm wondering if it's just my phone or if nobody has commented on it. I first noticed this about two weeks ago, when my phone refused to find service. I was stuck with the little X next to the signal meter. I figured I was just in an area with poor service and didn't think much of it. An hour later, still, no service. This time I went outside where I know I have good 4G service and nothing for 5 minutes. I enabled airplane mode and disabled it, still nothing. Turned the phone off and back on as a last resort. Still nothing. I ended up finishing the day with wifi calling as that still worked. Sometime later my phone began receiving service again so I thought it was a fluke issue.
Then, just yesterday the same thing happened. This was when I rebooted my phone (which bypasses the fastboot feature) and service was restored right away. I called T-mobile and they said there weren't any network issues in my area and they had never heard of this issue before on the Amaze.
So, this is where I'm asking if anyone has heard of this before. I'm running a stock ROM and it hasn't been rooted. Thanks for any comments!
This might help just a touch. I do live in an area with decent service but my couch and bedroom are deadzones for some odd reason. I bought these signal boosters for 2 bucks figuring "what the hell, I'll give it a shot". No more dead zones, and data went from E to G. Not a miracle worker but for a couple bucks it keeps a signal at least.

Wireless Coverage
I have 2 brand new Amaze 4G for a few months now and had no problem with the coverage. I know the coverage is good with full signal bars and have not found any issue with coverage.
Sometimes, different phones have different received signal sensitivity. Also depends on user behavior. If you are always using a handsfree device (cable or BT) and your phone is in a bag, then your coverage is reduced by your action. The best coverage you can ever get is when you have line of sight (unobstructed) to the cell towers.
There are a few issues with your problem:
1-Poor inbuilding coverage
2-Poor coverage in your area
3-Network optimization issue
4-Hardware issue
If you are going from 1 bar to no bar, then most likely you have coverage issue. You lost signal since the level is already very low.
If you are going from full bar to no bar, you might have hardware or network optimization issue. Try your phone is the city or area with known good coverage first. If the behavior persists, then you have phone problem.
I used to manage wireless network for carriers.
same issue
I've had the exact same thing happen to me. Red x, no signal except wifi, in places where signal is not normally an issue. Battery pull doesn't work, return to signal seems arbitrary. Had the same thing happen with my Desire. I have no answers, but you are not alone.
Yup, it happened with my first Amaze. I got it back in January and started playing with it - rooting, custom ROMs, etc. Then later that day, the signal just died on me. I thought I must've screwed something up, so I flashed back to everything stock. No luck. I waited for half a day, then it randomly started working again at night.
You probably noticed tha tI said that happened with my first amaze. That's because after that signal issue, I discovered that my camera stopped working. I returned it to T-Mobile and they sent me another one. This one is working great though.
Well thank you for all the input so far. Id like to say that this isn't my first cell phone and I'm not new to weak or poor signal areas, especially from T-mobile. I was using my phone at work at the time, which has anywhere from no signal to 3 bars depending on where you are. This wasn't one of the cases that I was standing in a dead zone when I checked my phone. I had no signal for several hours, including over 30 minutes of standing outside trying everything I could think of. I have had excellent signal outside in the past, exactly where I was "Hiding". I got the Amaze because I was tired of playing with my old HD2 and having to work around bugs and possibly not receiving calls. So far, I'm not happy that the radio seems to quit responding all together and leaves me without a phone (minus the wifi calling but I'm not always around a hotspot).
I also experienced a dramatic signal loss at home, going from full signal strength to maybe one bar right around the time that I first had issues. I don't know if this is related or if this is a completely different thing.
I am 99% sure this is an error with the phone - probably software related with the radio driver(s) or radio firmware. I guess I will try taking it back to T-mobile and seeing if they could exchange it for a new one. I was just really wanting to avoid that as I finally got my phone setup how I like it. Again, Thank you for the input and let me know if you are having the same problem or if you know of a solution.
I am on my third Amaze and also tried a Galaxy SII X due to the same problem at my home. Even the Samsung did the same thing. In my house and especially in the driveway, the signal varies wildly between -85dbm to as low as -111dbm. The frustrating thing is once it loses the signal, it doesn't seem to reacquire it without a reboot.
I'm with Telus, and they said they will check on it, but I'm not holding my breath. In my immediate area, outside my house, the signal isn't great, but it will usually hang on. I have been to different cities, and all has been well with it. Coming from a rock steady 2G Touch Pro II, I am disappointed as well..
I am new here to this site, but I am having a similar problem with my Amaze. At work I always have a weak 4G signal, but the last few days it has been gone altogether. I have full phone service (4 bars) but no data. The 4G indicates I have signal, but I can't connect to anything on the web. I called HTC and they had me pull my battery and sim card so they could send a "reset signal" to my phone. After my phone came back up I had faster service than ever, but it only lasted a few minutes and went away again. I am thinking this is a phone issue. Oh, the Amaze is my first Android. My only previous smartphone was my Nokia E71x.
I know if I have WiFi calling selected, an x will show up on my signal if i turn WiFi on. I've personally only had slow data in the area I work. I blame it on the fact that it is a busy corporate park with lots of hotels, cuz my signal is fine elsewhere. Try calling tmobile and seeing if they have known tower issues in your area. I know I had that problem with sprint and they sent me a free airave. Maybe tmobile could do something similar if its.a known problem.

It's most likely a network issue. I get the same thing, it will timeout/refresh the network where it will not get a signal for about 30 seconds a few times per day. I blame the network, since the same thing happened to me with my mt4g

Thank you! This fixed it for me. It was happening only today while I had WiFi enabled, it would turn the mobile radio off completely and the box would be grayed out so I was unable to turn it back on. I had my sim updated today to enable wifi calling so after I read your post, I turned the wifi calling off and the mobile radio signal came back immediately. Strange bug.

I was told It's by design. It saved battery life by not constantly searching for a mobile network it won't use (due to wifi calling). It's not like you can hand off the call to the local network. I do notice that if i start walking outside, once my wifi hits a low signal it logs back on the network.

There is actually an option to specify how the WIFI calling works: either all the time or only when cellular signal is gone. Sounds like you have it set to be on all the time. This means that if you have a good WIFI connection, the cellular radio is shut off and all traffic goes through the WIFI calling app. The other option (which I use) only uses wifi calling when there is no cellular signal.
I have lost cellular signal 3 additional times since my last post. Its not just that I'm in a bad spot and I have no signal for 30 seconds. This goes on for 30 minutes or more - up to several hours. I have found that rebooting the phone fixes it as I believe it completely (as much as possible) removes power from the radio and requires it to be completely re-initiated during the reboot. Simply shutting it off doesn't work as the quickboot is enabled and most likely doesn't perform a complete re-initialization of the radio. My only guess at this point is that there is some kind of possible leftover code from development which never was removed from the radio (this happens more times than not). It could be a timeout or simply causing the radio to hang because of 1. excessive heat generation, 2. excessive power drain, 3. buffer overflow, 4. excessive RF transmit power... In any case, one of those issues could trigger an event in the radio to cause it to simply stop responding.
I am in the process of trying to get T-Mobile to get me a new phone as I am outside of the 30-day window. I have also confirmed it with them that this was not a tower issue.
Thanks
htc amaze 4g signal issue

Hmmmm who is dear? Lol.... Ne ways, well first off, I commend you for digging this thread up rather than just starting a new thread without even looking first :thumbup::thumbup::thumbup: I can't say I've ever seen someone who hasn't even been a member for 1 full day do that. Shoot, I see senior members start new threads or pointless threads without searching first, so good job haha.
Ok, back on topic now, if it's only dropping when you go in your room, then I don't think it's anything wrong with the phone. Not sure who your provider is, but u may be able to call them and have them look up your address and tell you what kind of signal u should get outside your house, and what to expect inside your house. I know t-mobile does at least

Well your situation is a little different than other peoples in this thread if u can't connect al all. Ok wait so first off, it won't connect to a network at all? AND you only paid 50 bucks for it...? Sounds a little fishy to me bud, why did he say he was selling it...?
Next thing, I don't know why a t-mo rep would tell you to root the phone, rooting has no effect on your signal strength or your ability to connect to a network.
And lastly, is the phone a T-Mobile branded amaze owhat carrierr...? and will it not connect at all, period, or can u make calls just not data...?

I am wondering is there a way I caj say extend my antenna, I'm working in camp in northern Alberta, I get service 3 ft out my room door, sometimes inside it... Just trying to figure a way to make it so I have service in my room apart from buying a booster lol going to go get a phone with telus on days off but that's not for 34 days
locked & loaded
Some phones have an antenna port under the battery cover. I don't see one on the 3d, however I just got mine a few weeks ago and never really looked too hard.
They also sell some signal boosters that will improve your service.

I got a solution for you that you will love!
Contact sprint you need to prove to them that you do not have service...
I'm assuming your on sprint if not im sure other providers offer similar options
In my house I get no service sprint sent me a device called a airwave. It uses GPS satelites and an internet connection to host your own personal network for your home and outside. When you make a call it beeps 3 times showing your connected to this network. I get 3mbps down from 3g inside my own house its like wifi but more importantly I can talk on the phone without daggon calls dropping.
PM me if you have any questions would love to help you plus I'd like to reach that 10 post bull**** that xda imposes on people.
Otherwise there are antennas you can mount on your roof with signal repeaters may also be helpful. Go with the airwave if available for you!
EDIT Sorry didn't read your entire post... Idk if your living situation is permanent or not but.
You may be able to trick sprint if you tell them you still live in the US you can set your airwave up anywhere assuming you have a decent internet connection. **** you could be at the northpole on a satelite isp provider. O wait xda is saying I have to wait 5 minutes between posts edits... so before i smash my monitor im going to grab a chocolate milk

Curious issue with my Titan II. Cellular data connection just fails at random intervals. Cycling airplane mode or rebooting the phone is the only way to get it back. HTC blames it on AT&T and AT&T blames it on HTC. I've spent hours on the phone with each. Even got a new Titan II from AT&T, but it went into this constant reboot loop, so I went back to the first unit.
Now comes the interesting part: I live in Detroit and have been traveling to FL quite a bit, this year.. and the issue DOES NOT HAPPEN IN TAMPA. Phone runs perfectly well, there. Here in Detroit, cellular data "up" time ranges from 5 minutes to 14 hours when static. 2 minutes to 20 minutes when driving around town. Drops are less frequent when streaming something.
HTC Titan II stock (FW: 2180.0400.118011.502)
Windows Phone 7.5 (7.10.8112.7)
4G SIM card (3rd one)
Appropriate data plan
Serious thanks for any ideas anyone has. Do I add an APN, throw the phone against the wall, or what? Please do not suggest I change to a different phone as that is not an option.

Yes, I'm facing the same issue.
It seems something related to wifi sleeping when the phone goes stand by and the solution could be keeping it alive in some way....like streaming..
I hope this will be fixed with AT&T Tango 8773 Update (Once it finally come....)

Are you sure you aren't hitting "black spots" on your network? If you have random connection drops in only particular area it is likely the masts and AT&T issue. I've swapped my provider from the one which did 2G/3G signals to 3G only provider. 3G only has better coverage and lesser black spots on the network and hence I hardly see any drops in connectivity. Don't hard reset or anything, it will only make you re-do the whole phone, won't help the cause.
Have you checked if two golden pins on the back cover are making good contact with phone?

Have to rule all of that out as it doesn't happen at all in Tampa. I can drive from Ybor City to Clearwater and back and never need to reset the phone. Here at home, I have four bars and will lose cellular data with the phone in a static location. Driving around in Detroit is guaranteed to make it drop cellular data even with the phone lit up and active. I can have Navigator running and it'll just quit loading maps and giving directions until I cycle Airplane Mode. In Tampa, this doesn't happen.
In Tampa, I've gone the whole week without any need to reset the phone. I can't walk from the gate to baggage claim in Detroit before it loses its data connection.

UPDATE: Cellular data connection is a little better with WiFi turned off. It won't lose it as quickly in a static location, but still loses it as I move between towers. Also had to reinstall a couple of apps that had stopped launching.
Is forcing Tango an option?
I have the same problem,
I live north of detroit.
my phone has been in to htc repair 3 times, i think they have replaced every part in it, the last time i got it back it held connectivity for 11 minutes.
this is on my home tower as well as several towers around me.
Normally all testing was done with wifi off, on towers where the lumia 900 and my wifes iphone have never lost data.
i have been waiting a week for a htc level 2 rep to call me.
we shall see
Keep me posted. Last time I spent time with HTC, they decided that - since the issue only happens in Detroit - that it was AT&T's problem. AT&T, naturally, claims that the problem doesn't appear on any other device, so it must be the device.
Can't wait for Windows 8 phones. I'm getting one.. ANY one.. the first day they go on sale.
Well I just got off of the phone with a level 2 rep from HTC, who seemed pretty confident that the problem is the rear cover. He is sending one out, and says if that doesn't fix it then it will be a phone replacement.

So, I'm in Florida for the week and noticed something.
In Detroit, the status bar says "4G"
In Tampa, the status bar says "LTE"
As before, I have not lost cellular data connection since I landed in FL. Kind of rules out the battery cover as the issue is gone, here. It appears the issue goes away in LTE areas while it's present in areas yet to get LTE. Detroit's LTE rollout hasn't happened, yet. So, it appears I've got another month of suffering before the problem is rectified.
One other note. With Internet Sharing set to ON...
In Detroit, my wife's laptop connects to the phone and can get internet.
In Tampa, my wife's laptop connects to the phone, but cannot get internet. It gets the error msg: "your computer is trying to use a dns server that is incorrect or doesn't exist"
My laptop works flawlessly connecting to the phone's Internet Sharing both in Detroit and Tampa. For the life of me, I can't find anything different in her settings over mine. Both are Win7. Hers upgraded from Vista, mine x64 and new this fall. Also, two internet-capable televisions connect to the phone and get to the internet flawlessly. But something with LTE doesn't like my wife's computer. Odd.
Honestly, I adore everything about this phone except for the data connection issue in Detroit (and a few other areas, it seems).
There HAS to be a setting or SOMEthing I can tweak to get this thing to work in Detroit.
Check battery cover, radio negotiation, firmware of radio

Hum.. that's curious. I had the original titan with similar issues.
I disabled wifi when not connected. I replaced battery cover also. The titan2 supposedly fixed that issue with the battery cover because it was a design flaw.
The radio supports 2G, 3G/4G/H and LTE. You may want to check it. You can set the radio it uses and not let the firmware decide which radio to use. You can check the service menu, I forgot the code. Just search for it.
If you use 2G, data and voice are not supported simultaneously. Check and make sure the contacts on the battery cover and on the phone are clear of debris. Use a solution to clean the contacts on the phone.
In the past I manually set the radio to 3G (HSPA and HSPA+) [HTC Pure, HTC HD2 on at&t]. The 3G radio is mature and should have less issues with the radio negotiation.
BTW, there is a keep alive wifi app also.
Thanks. I'll have to look for the codes. It's pretty obvious after going back and forth so much that the Titan II has a flaw with the way it handles AT&T's 4G. Scanning the maps from others who have had problems all show that they're in areas with 4G but without LTE.
Yeah, if I could force this thing to do LTE or 3G I think we'd be fine. It's the Best Phone Ever so long as it gets LTE, 3G or Edge. Anything else and it's crap.
Yes, back connector is okay and I've done this every way one can think of and kept notes. WiFi doesn't matter. On or off, the T2 will lose cellular data connection randomly in 4G areas. NOT in LTE areas. I'm only unable to test it on other carriers.
Similar problem with data
So I have had a similar problem -
I had a Samsung Focus, great phone, but I wore out the USB port - wouldn't charge consistently or sync. I figured I might as well use the insurance I had been paying. They sent me a Titan I - it had the bad microphone issue. So after some messing around they sent me a Titan II.
It has never had consistent data connection. I am in an area where I get the 4G icon (not LTE).
My experience tells me that if I move around and change cell, or lose signal in the cell I am in for any reason, then the phone will NOT connect back to data. It can (almost always) still get phone calls and send/receive texts and so on, but no data. Toggle airplane mode always fixes the problem, until the next time.
Originally HTC wanted to send me a new back cover - AT&T have been completely useless, they have no idea. Eventually after messing around with factory resets, powering on and off continuously, another new SIM card, HTC decided they want the phone repaired or replaced (level 2).
It is still inside the 30 day limit for exchanges from Assurion (AT&Ts insurance carrier) so it's getting replaced. I'll let you know if it fixes the issue, but I haven't been in an LTE area so I can't check that.
Personally I think it is a problem with handing off/reconnecting to 4G tower service - we'll see......
Anyone have the radio codes?
I've had the same problem since I got the device as well; but have noticed that it doesn't happen in all areas around me. My house is one of those areas though that I always lose connections. I've tried every APN / idea I've found on the internet with no luck. It's clearly something to do with AT&T towers. The only think I've not been able to try is a different SIM card in the same phone since it requires a '4G' sim card to even work at all. However the same SIM does work fine in '3G' only phones.
Going with the radio idea, does anyone have the codes to turn off the LTE radio? I just saw the list saying this phone will be long gone before AT&T ever gets LTE in Colorado so maybe just turning it off would help. Every code i found was for the T1 though and it didn't work on my phone.

UPDATE: HTC insisted on sending me a new SIM card cover (since it contains the radio's antenna). Despite my argument that the fact it works in Florida negates antenna as a suspect, they sent it along, anyhow. Naturally, there is no change. It still randomly drops cellular data. And now, I've picked up another spot on the freeway where my calls get dropped. Granted, it happened ONCE, so that could be any number of things. Long story short, it's not the antenna.
Next idea?
Well, I'm in Florida and found a spot where the phone fell back to 4G from LTE. Data issue returned. So, that takes geography out of the equation. The phone can't hold a data connection when using 4G. So, should I go for a fourth unit?
My addition:
AT&T recently rolled out LTE to my area in CT. I never had the problem before on straight 4G. Now, when I go from LTE to 4G (my drive every morning) data just stops working. I push it in to airplane mode and back out again and it works.
BTW - I am running Tango, so that is not likely to be a fix unless a radio update is released with it.

AT&T just switched on LTE metro-wide, last night. Now, the Titan 2 performs just as it does when I'm in Florida. It's nice having a data connection that'll stay good all over town, again.
I have spent some time discussing this with HTC and AT&T. Actually just got off the phone with HTC level 2.
I too have gone through all the options - new phone, new cover, new SIM card (you can just go into AT&T and ask for one, no charge), hard reset, everything.
From the information in this thread, and elsewhere I can say that the phone drops data on one of two things happening:-
- connection to tower is interrupted in current cell, but is re-acquired
- connection is handed off to adjacent tower as you travel to a new cell
Both these things will drop data IN 4G AREAS ONLY. If you are lucky enough to have consistent LTE in your area, you shouldn't have any problems.
Right now I'm working on getting the service menu codes so we can play with the radio settings. It sounds like HTC support reps have been forbidden to give these to end users on windows phone devices (I wonder why??!!).
If I get this information and it provides a fix for this issue, I will (obviously) post it, and I imagine HTC will as well. Here's hoping.....

I have noticed a good amount of threads popping up with people talking about signal issues, 3g/4g issues, connection issues or phone issues.
I was wondering if we could find out what the common factor here was and what fixes everyone has been using. I know that some people got new sim cars, problem solved. Some people restored to a full stock image via odin, problem solved. Reflashing the stock radio, problem solved.
So has anyone had any other solutions, issues or any other info regarding signal issues or anything relating to that?
Been through this with the Nexus, S3 and S4
The solution is to buy a Motorola RAZR or iphone.
Things that do not work -
Upgrading to the newest version of Android
Updating the Radio
Changing it to CDMA only
Lifting one leg up, putting one hand on your head and pointing your other hand due north
Attaching a sticker antenna to the back
Using some custom baked firmware
Reading posts from people who claimed they've solved the problem.
Using Bluetooth
Not using Bluetooth
Buying a special case
You can get a femtocell repeater if you are in an office or home where you get little reception but it won't help you on the road or just visiting a friend unless you want to set it up every place you are stationary.
In the end trying to fix the radio design flaw with a firmware update is about as useful as trying to fix a shattered TV screen by adjusting the brightness setting. If you read the radio issues on the Verizon Nexus and the Verizon S3 there are a lot of people claiming they solved it but in the end it still sucks.
I have zero issues with data on my s4 I'm on the east coast running clean rom 1.6.5 solid LTE everywhere..

Unfortunately this is very true, every other VZW Non-Samsung phone I've had hasn't exhibited this issue.
Motorola and Apple have had their share of radio/antenna issues as well.

I'm not really talking about comparing the signals to the iPhone or anything. I'm talking about finding a common denominator for the group of people that are suffering from signal, connectivity or phone loss on the s4.

Trying to tie it all together with a common denominator is a logical fallacy. It would be akin to trying to find a common denominator for everyone in the world that has a chronic cough. The causal factor varies from case to case.

The common denominator is we are on Verizon and have Samsung phones. If you want to go further, you could do a subset intersect and see we have the S4 on Verizon. It's like saying what is a common denominator for those people who have safety issues with the Chevy Corvair. It is a design flaw that only could be fixed by replacing the phone with a different model. Trust me, I went down this path with the Nexus and the S3 - magical firmware updates were dangled by fanboys saying they would come and fix the issue but the firmware updates came but they never fixed the issue.
If you want better signal, you could buy a different phone or get a femtocell repeater. TRUST me, I would love a magic bullet to fix the issue but there isn't one. On the plus side you'll get a ton of helpful posts from people saying they never have issues or you must be doing something wrong.
I dont know what is up with all ur phones, but my signal is much better than my old Galaxy Nexus/RAZR M. I am getting 2-3 more bars of 4G at work. At home it use to be only 3G, but now im getting at least 2 bars of 4G. I don't even turn on my WiFi anymore at home or work.
bars dont really mean much...
i have had some odd issues where i will be in home depot or grocery store trying to look something up and it will fail; market doesnt work, browser doesnt work. phone calls and texts (over gvoice so data) wont work.
the razM i had before this was solid. my GF still has the razrM and we were at grocery store other day and if you went the their app there was a coupon to add and the s4 was refusing all data again.
i had similar issues with an old HTC Dinc2 and it was then i started using an app "restart connections" to get data back but it doesnt fix the issue on the s4 i have. if i reboot the phone data comes back.
i have also twice now went to use gmaps and it it attempts to look up an address for 3-5 min and i finally restart the phone and go back in and find the address ASAP after reboot.
something funky is going on and i havent taken the time to try and look at syslogs yet...
i am running the stock MDK rom (rooted) on VZW
reception is odd

I'm in a difficult reception area in the middle of manhattan. Funny thing is that I almost always have 4G - even in my house. At the same time, I never have more than two bars of signal in my house. I have occasionally had trouble making calls (I think the tower I'm reaching is too busy), but once connected, no one has complained and dropped calls are rare.
I don't understand this and don't know whether to complain or not because although there are almost no bars, there is reception that is pretty good. So I've left well enough alone.
This phone gets decent reception for me. Dropping from 4g to 3g is new for me after coming from an htc rezound though. My rez NEVER dropped 4g in my city anywhere. Guess radios is the one thing htc can do right. My s4 drops to 3g in multiple areas sometimes. Hopefully Samsung keeps getting better with their radios and they'll have me as a customer for more years of they do

This is basically the same issue I have. Only a reboot/data toggle won't fix it. I had two bars(not that it means much, I didn't look at the db) and it kept saying it was communicating with the tower via the green/red up/down indicators, but I couldn't access any data services. I moved my car approximately 500 yards to the south and viola, data again. I don't get why I could make a call, but I couldn't access data.
That being said, it's still better than my Gnex for....well...everything. But I would say worse than my Rezound, Bionic.
i ended up flashing the modem with the ME7 version, while keeping the rest of the ROM on the original MDK. that was about amonth ago and i think ive only had to reboot 1-2 times because of data drop.
I received my new XA Ultra from Amazon yesterday. Popped in my SIM and started setting it up. It had two software updates out of the box, so I applied them, then started installing apps. I noticed that my cell connectivity would completely drop (no bars), then come back. When I checked in the Access Point settings, the option to discover carriers would appear, then disappear.
I assumed it was some kind of software corruption, so I factory reset, but it continued doing it. I also tried pulling the sim out and putting it back in several times. I can only assume that I somehow got a defective unit or that one of the software updates applied the radio incorrectly. I processed a return with Amazon and have a replacement coming later this week.
I hope Amazon doesn't turn around and resell it through warehouse deals. I have received a few devices from them that they clearly didn't test and I was very explicit in my comments for the return. I'm just hoping that my replacement doesn't exhibit the same issues because I'm not sure what else it could be. It's not my SIM. All of my other phones stay connected to AT&T just fine in the same spot.

Did you check before purchasing that it would connect to I'm guessing by AT&T US network's I know yours are different to ours in the UK. I've not had any problems with my normal xa but I'm in the UK

It's definitely fully compatible. It even downloads the correct APNs, but then they just disappear and the signal drops completely. I get full LTE speeds when it's working and nothing when it's not. I also tested a T-Mobile SIM and, while it holds onto the signal longer, it does the same thing (drops completely).
I plugged the phone into a computer and did a complete software restore, which didn't fix the issue. At this point, I'm sure it's either hardware or a really bad ROM update. I'm hoping it's hardware, because if not, that means that the replacement will have the same issue after applying the software updates to it.
This is my second Sony xa ultra with the same issue here's what happened
Purchases from best buy didn't setup until I got home had 2 update applied them signal drop and reset constantly I figured it was because I have bad reception in my area but the more I looked at the phone I noticed the build quality on the metal bumper wasn't sealed in some areas so I grabbed the packaging and headed back to Best Buy keeping note of the signal issues as I drove there (disconnected from WiFi of course) I noticed the signal did not drop connection at all on the way to Best Buy return the phone and explain to him the issues that I had at home with the signal and also wasn't happy with the build quality defect so I returned it and exchange for another one immediately popped the Sim in it downloaded my APN and I had LTE drove home no drop issues connected to wifi installed the two updates then I drop issue return

The replacement model I received from Amazon did it as well. Right out of the box, before updates, it was dropping the signal. Are you on AT&T?
I watched it really closely. I think I know what's happening. It's not falling back to HSPA. When the LTE is too weak, it simply drops completely until it can reconnect to LTE. If you set it to HSPA only in the mobile networks menu, you will never lose your signal. I tested it with both T-Mobile and AT&T with the same results.
This is a pretty major defect.
You might be on to something, yes I'm also on AT&T.. but I can't find HSPA in mobile network should it be GSM only or LTE (preferred)

It should be something like "GSM/WCDMA Auto" or "WCDMA only". Basically anything without LTE (except CDMA).
I'm honestly just glad to finally have someone else confirm. The chances of having two defective units in a row are extremely slim. Really liked the device otherwise, too, especially for the price.
I tested it for hours. I never got a disconnect on HSPA when I had that set. I just wasn't willing to live with that restriction.
Me as well!! phone is perfect for the price I paid out of pocket I had a BB gift card. I've been shopping for the right phone for a month now I've had about 5 phone from 700 to 200 bucks the expensive ones we're worth the price and the cheaper ones didn't feed my power craving I'm pretty happy with this one for the moment, thanks for the tip
This may be an AT&T SIM related issue.
I have T-Mobile and with my T-Mobile SIM I have no problems. I tried my friend's AT&T SIM, downloaded the APN, rebooted, and sure enough signal drops just like you're experiencing.
I'm having the same exact issue as previous posts with my Ultra. I purchased the unit from best buy the day it came out and using it on AT&T. I love the phone but the issue with completely losing connectivity is a bit annoying. Called customer service and they gave me the same website to fix software issues. Just curious as to why I'll be in same location without movement and then all of a sudden lose my signal.
I have the same problem using cricket wireless which is using att's network, lte signal comes and goes, this is becoming really annoying, is there a fix for this already, or should i return the phone
So I just got off the phone with Sony and they said I would have to send in the phone for repair leaving me with no phone. I've had issues before with phones and the companies just send you a new unit with a box and return label to send back defective unit. The rep said maybe my provider would give me a loaner phone.... Smh Looks like it might be time to leave Sony. Maybe I'll have better luck with the Lenovo Phab Pro 2 coming out next month.
Same issue here, right out of the box today.... Using AT&T reseller and I would have to agree that it is an issue as was mentioned earlier where the phone is somehow not able to fall back on to HSPA on a weak LTE connection so it just completely disconnects. Strange thing is where I am using it (at my desk in my office) I never had an issue of LTE dropping off with other brands of phones. As soon as I left the cell area and started using it at home or at another location further away I had no dropped LTE signals. I think Sony support will be useless unless we can somehow get past the standard support desk. They told me they have no higher support I can be directed to, that I would either just do a software repair (which I assumed correctly would not work) or send it in to service. Not sure what I am going to do at this point, cannot have my phone jumping out of service every 2 minutes during the work day. Any other suggestions would be appreciated.
EDIT: upon further review (using LTE discovery App) it appears that "some" At&t sites are having issues staying connected with LTE band 17 on this phone. I drove up to one of the sites the phone has issues with. It had a solid,strong signal within 1 block of the tower and band 17 still disconnected the radio completely. As soon as it reset and moved to band 4 it stayed on without disconnecting until I moved away from the site far enough for band 17 to kick back in. At that point it continued to disconnect every 1 -2 minutes until I moved the phone mode into HSPA preferred. I don't know what to say about this, band 17 works great on 2 towers within 10 miles of here, but some others and this tower causes the phone to go into a fit. Clearly the phone has LTE issues as any other ATT LTE phone on band 17 I have used in this area has always worked just fine. Anybody have an opinion on this???
I have what I think is the issue, now if we have any way to get this information to anyone who can actually do something about it. I have 2 sites by my home that the phone works flawlessly on LTE... no dropped LTE signal whatsoever. Here is the difference... they are band 17 ONLY sites where the sites my phone is unable to hold a LTE signal when the At&T site is broadcasting both band 4 and 17. That would explain why the rest of the sites around where I work do not maintain a signal either. We need to all contact Sony support and somehow get this information thru to them. The issue is the phone clearly being unable to handle a site broadcasting 4 and 17 which I think is a majority of them.

It's still not falling back in HSPA like it should. If it has difficulty with an LTE connection, it should not drop connectivity completely.

Agreed, but keep in mind that my XE ultra was 1 block from the tower with incredible LTE signal strength and it still completely shut the radio down and restarted. This is not for lack of signal but a complete inability for it to handle a band 17,4 tower. Although it would be great if it just moved into HSPA, that would mean your phone would be in HSPA 80% of the time, even when the LTE signal was completely adequate for the area. This clearly is a defect that makes the phone basically unusable (as it continually shuts the radio on and off) until Sony can figure this out. My concern... there is no way to talk to anyone at Sony that can do anything about this until they get enough support complaints directly related to this issue, this could take months not including the time they need to program an update and fix. Very frustrating.

Frustrated with this as well, hopefully sony fixes this problem more sooner than later
Received an update yesterday and I can't confirm 100% but it appears I haven't had as bad connection (popping in and out). I'm in Houston btw.
I got the update and so far phone has been working fine
The latest updates from sony fixed this issue.. so happy and enjoying it now
