[Q] 4G jumps from awesome to null - Thunderbolt Q&A, Help & Troubleshooting

I want to know if anyone else is having this strangeness before I call VZW;
Without moving an inch my signal goes from 2 bars of 4G to 2 bars of 3G and then back again. I set the phone down and wait a couple minutes and it jumps to 4G again. Very sporadic.
When I run Speedtest sitting at my desk showing 4G I get 6.5MB down and 25+ Up. Then, 3 seconds later when it jumps to 3G I am getting less than 1mb down and 500k up.
I have powered down, pulled the battery and held power button, the powered back on. (Several Times) Same results.
So far it's only inside my building so it could very well be environment related. I just want to toss it out there and see if I am the only one.
Thanks!

LoL, I feel your pain. It's the building you're in. I was thinking the same thing. As soon as I step outside, it's 4G central. You're not going crazy or anything.

When I'm on the edge of 4G coverage, mine does the same thing.

So far, when I'm at work is when I have that problem. It's quite annoying actually. Every other building seems to be fine outside of where I work.

You ain't lying! I was like WTH! I honestly thought I broke the thing until I started walking out of the building. Kinda sad that it doesn't really work indoors at work. Like you said, time to get a new job... not yet, I like what I do lol!

When I'm in an edge of 4G area I notice it doing the same thing, it has having a hard time deciding what to do. Rebooting or putting in airplane/taking airplane off seems to fix it

Thanks folks! Glad to know it isn't just me. I did notice it happened when I was at the gym too. But in the car, truck or outside... Epic Awesomeness!
Always good to know I am not crazy, or at very lest not alone in my insanity.

Same thing happened to me yesterday, although slightly more weird.
I was happily tethering away at the office on a nice strong, fast 4G signal for a few hours, then all of a sudden data dropped out completely. Restart the phone and it only shows 1TTX, but eventually flickers up to 3G, but won't go back to 4G despite numerous reboots. Eventually it settled back down to 4G and all was well.
I guess it was some kind of tower problem, as my location doesn't appear to be anywhere near a non-4G area (see map below). The area my office is in (near the 405 fwy and Van Nuys Airport) has excellent maximum speed coverages by AT&T and even T-Mobile; it would be shocking to me to learn that VZW in the same area isn't full 4G (it's not as map shows).
Hopefully this was just a fluke, but it has me nervous and I'll be keeping an eye on the performance during my 30 day test period.

This is very similiar to what happened to me last night at a restaurant around 8:30pm in Tustin CA. Had one or two bars of signal, was streaming YouTube fine, data connectivity cut out even though signal was same, cycled through airplane mode, after a short period it came back at 1x then eventually back to LTE. I thought the LTE equipment bounced at that tower but it now sounds like it happened on a wider scale.
I guess it helps to post the following info to help correlate:
Occurrence: 1
Date and time: Fri 3/19/2011 ~8:30pm pacific time
ROM: 1.12.605.9 non-rooted

Same here. I'm still trying to figure out the battery life hand over from 3G to 4G and back. It does NOT appear to be graceful.
I too have had to revert to airplane mode to get 4G back up. What end up happening too is that 4G will be listed, but push notification stalls badly even though it seems like a solid signal.
Last night I turned off 4G the entire night and push was working fine in the morning, nearly instantaneous.
This morning I turned off 3G and forced 4G and after 4 hours everything seems fine with no push notification latency. So perhaps the hand off on the phone is real bad between 3G and 4G.
I used phone info from the market to toggle 3G and 4G, [email protected]

I've had a couple of instances I suspect over the last three days, but only the one that mentioned above where I can be sure. For me it was:
Fri 3/19 ~2:00 PM Pacific
stock rom unrooted at the time.

I would expect that to go away as they expand coverage, remember that this network is still being rapidly expanded.

Its 30 days for a defective exchange but 14 days to exchange or return the phone completely FYI

Here is a thing I have noticed and a friend got me thinking
If you pick up a call on 4G and travel into a non 4G area... your call will drop. Its weird because no one said this phone could support LTE voice.
But if you pick up a call on 3G and travel into a 4G area everything is fine, just be stuck on 3G until you end the call. Same goes for data, I tested this out with pandora and stays stuck on 3G until i stop.
The manager at the corporate store told me they were not having any problems with signal hand off's but I think he was lying or didn't know. I work as an agent at the edge of a 4G boarder and get tons of returns or questions about the service on the 4G air cards for people who live in the area or near the boarder.
Signal just drops before it decides what its going to try next, super annoying

Mine was switching all over the place and then would completely shut off with no data connection. I kept getting a retry. Finally I took the cover off and just put it back on and now it seems to be working fine. I guess the antenna was not connecting properly.?

you guys should try an evo on Sprint 4g and laugh at the wimax coverage.

Sudden signal drop. Phone issue?

Hey Gang.
Last night I noticed that my phone didn't have full signal (4 bars) in my house. This is the first time since I've had the phone.
After playing with it for a while I noticed that if change from 3G to Edge then my signal strength goes from 1-2 bars (-110db) back up to 4 bars (-73 db).
I'm not sure if that's normal behavior. I've also noticed the the phone gets hotter than normal when transferring data via 3G and the battery drains like crazy (lost 50% charge over 2 hours of testing this morning).
I called my provider (Rogers - I'm just north of Toronto) this morning and they say that the one tower in my area seems to be working fine.
I did a factory reset using SEUS but still have the same problem.
Any ideas? I thought I'd try to reseat the antenna but I can't find the damn thing.

Of course after all we are all here to help yeah?
So after driving around and visiting the local Rogers shop, it appears to be a tower issue. Looks like the phone was working fine in the store and in town. I called tech support and they're sending someone out to the tower near my house. (<1 km or 1.6mi from my house). There was a power outage yesterday so that my have caused a problem. I'll post an update in a few days after Rogers checks the tower out. I'm hoping it's that. I'm thinking the extra heat may have been from the phone cracking up the antenna to try to connect. I remember someone say that in low signal areas their batteries drain fast.

How is the GPS on the evo 3d?

i am ready to ditch my vibrant piece of crap and want a phone that has working gps. how accurate is the gps along with programs like my tracks and runkeeper?

Ditto. It has nailed me within 3 feet while zoomed all the way in on the map. As I move around my yard it moves almost instantly.
Used a few times in Chicago today, near O'Hare airport which is known for **** signal. Worked perfectly.
Locks on quicker than my ogEVO.

If by accurate you mean reading you as 3 streets over...
not sure
I use mine with a running app Runkeeper. It was very good the first 2 times I used it showing 3.08 miles for a actual 3.1 mile distance. But yesterday is showed 5.37 miles for the same 3.1 route.
I hope it was just a glitch which happens depending on clouds but yesterday was clear.
meh
Meh, it gets poor signal indoors. Outdoors, it's often off. To truly test the GPS, you need to disable WIFI, otherwise it will use the BSSID's of nearby wifi hotspots to show your location...
I noticed that on the OG Evo in Maps (Maps, not Navigate), it would usually snap-to-street while i was driving. Now it doesnt seem to, i could be doing 50 down a side street and the map shows me driving through people's back yards on that street...
I use mine for logging runs and workouts. I wasn't too impressed yesterday when Cardio Trainer logged only half of my run.
NS4G didn't do that, lol. You could see where it would pickup and drop some sort of signal, and it repeated it numerous times while walking.
Running, it seemed to hold signal decently.
::EDIT::
Went running and I think its a CardioTrainer issue, not GPS. The GPS is constantly updating it seems like, just with CT I had a setting (auto pause after 5 seconds of no running) and I don't know if because of picking up and dropping satellites or what, but it was in and out of that mode.
Disabled that option (no big deal to me if it doesn't auto pause), and had a CONSTANT lock for the rest of the run after I did so.
I can get a cold lock inside within 10secs. Outside cold lock almost instantaneous. Gps rocks in this device.

It's really good and accurate. But, I never really use it so I can save some battery life.
I've been blown away on it. Google Maps on my Palm Pre used to take over a minute to load, and in some cases wouldn't load at all. After it did, it wouldn't aquire a GPS signal. On the 3vo on the other hand, maps opens up within seconds and it also aquires a GPS signal right away. The arrow even moves around depending where the phone is pointed. Can't say I have any complaints. My favorite feature is being able to stream pandora music and telenav at the same time, and it actually fades out the music while GPS kicks in.
I've been having all sorts of trouble with GPS locks. It'll lock on fine to start, but within a few minutes of driving I'll get GPS signal lost and it'll take a long time to re-acquire. I wonder why. I may have to consider taking it for a repair/replacement if I'm the only one seeing issues. It reminds me a lot of how my 4G acted when I was using an earlier CM7 build so I attempted the ##GPSCLRX#, but that didn't seem to solve anything.

I drove from Buffalo, NY to Summerville, SC and back last week (900+ miles) and my GPS was spot on the entire time. While in SC I used it to get everywhere and it was perfect.
Mine grabbed me within 5 meters. Spot On.
I used Cardio Trainer also and it was very inaccurate. I watched the signal jump all over the place, it was terrible. I took it back to Sprint and they reluctantly swapped it out. I haven't tested it yet. Others, please test walking or running. I will be taking it back and going back to my EVO 4G if it is not fixed. My EVO 4G worked flawlessly.
you can only test something like gps when your driving and have time to set it up, wait for lock, yadda yadda yadda...
on the three occasions that i have used it it consistantly dropped signal and was a PITA. as for gps... I prefer the 4g not the 3d
Strange...

My GPS has been working flawlessly since purchase. I play golf and use the Golf Card app and was very happy with the accurate results. However, today....the GPS was acting wacky. It was jumping all over as described above. I reset the GPS and that didn't fix it. After playing around with the phone for awhile, I finally got it to work as normal. Keeping an eye on this in case I need to get rid of this phone.
My GPS has been about as temperamental as the OG Evo on CM7. It sometimes has trouble locking and often is fairly inaccurate (it seems to work better in Google maps than other apps). The OG Evo on sense was definitely better IMO.

The GPS is very inaccurate and jumps around constantly on Runkeeper. For example, see these runs:
http://runkeeper.com/user/rcrockett/activity/41894800
http://runkeeper.com/user/rcrockett/activity/41487967
Zoom in and you can see how it's jumping around all over the place. It makes it seem as though I am running faster and a longer distance. The first link is a 10k, but it reported it as 7.15 miles. I thought was kicking butt!
I have not taken any OTAs. I hope this is fixed sometime soon. I wonder why this hasn't been reported more.

Random data outages

For the past day or two I have had connectivity drop completely. I don't understand what is going on or what is causing it. If I disable and enable data, it comes back. Wifi is not on either.
I have had these problems as well since I got my razr.
It also had a hard time disconnecting from home wifi and switching onto 4g

At least in Central Texas, 3G is down on 4G devices for a couple of hours at a time. 4G works fine.. Started last night and has been happening throughout the day today...
No amount of finagling the device made it reconnect to data other than driving to the nearest 4G city.

Even though it's a Bionic story, clearly this tells me they have issues with the Bionic and RAZR. Especially in areas where 4g signal becomes weak and data just turns off completely. This is what happened to me with the RAZR. Looks like they are on it so a fix is coming but 60 days (4/5 months after bionic release!) is too long so I returned it. Plus wonder if they figured out the RAZR is having the same problem. I would hope so.
I noticed this on the highway a lot, especially when using google music. 4G jumps in and out in terms of signal strength in some parts and then it suddenly cuts out. Super annoying
Happens to me constantly. At home more than anywhere else. But it is definately related to location. I have no issues at other locations. Annoying as hell. I can't even watch a movie on Netflix without it stopping 10 or more times

Update:
I seem to be losing connection regardless of signal strength. I was streaming shoutcast radio, had 5 bars 4g, and out of nowhere, 4g disappears. And returns 5-10 seconds later. Signal strength never faded. Also, does anyone know what the difference between when the signal strength meter and 4g are blue vs white? Because it sometimes is white and only seems to allow certain traffic. Don't know if anyone else has experienced that.
I've noticed the same kind of random data outages with my RAZR too on Optus in Melbourne.. which is kind of odd seeing as I work in the CBD
Looks like they having problems with data over at some other:

4g Turning Off By Itself ?

So I'm pretty sure my phone is turning off 4g by itself.
On Saturday I noticed I wasn't getting 4g at my house. I live in Los Angeles between Hollywood and downtown so I was thinking I really should be able to get 4g here and I remembered when I was showing my phone to my friend Friday night I didn't see 4g either, just 3g, and that was down in West Hollywood where it is very flat.
So I took a drive around and couldn't get 4g anywhere. Drove to a Verizon store and the woman downloaded LTE on/off and turned it on. I thought my phone had been shipped with it off but then I looked at a screenshot I took to send my friend a few days before and it said 4g.
Today I was sitting in my car after I parked outside my house messing around and seeing if I could get my mp3s to show up on my car's screen when the RZD was plugged into the car's usb port.
I saw the phone go to 3g. I have 4g at my house. I checked the network settings and mobile was turned on. I went into the LTE on/off app and LTE was turned off. I turned it back on and phone changed to 4g.
So apparently my phone's 4g is turning off by itself I believe unless I am doing something. But four Verizon employees, one that owns the RZD, told me you need an app to turn it off and on.
Is this happening to anyone else? Could it be something I'm doing?
I have seen the power settings do this when the battery level falls below some threshold. There is a setting under 'Power' that seems to affect this. It changes a variety of other settings too (like turn auto brightness off, etc.) but does not turn them back on when the battery level gets better. Looks like someone forgot context-save-and-restore.
I have disabled the power setting 'Economy' to see if things are better tonight when I let my battery drain below 10%.
I can't vouch for the first time it happened, but I know this afternoon the phone was at around 85% charge. I had been charging it before I left the house.
You know what? Both times I noticed was after I had it hooked up to my car usb. No idea if that could do anything but will try again tomorrow and see if it happens after driving around with it hooked up. Default setting is to charge only but today I did set it to data to see if that would make my mp3s show up.
I'm in california on business and I can't have 4g. I have to keep the phone in CDMA only mode and it keeps a rock solid 3G signal. If i turn it to CDMA/LTE then it will grab 4g for a bit, and ditch it and I'll have no data. No idea whats up.
As long as my 4g is turned on it works great.
So does this mean no one knows of a way I might be accidentally turning off 4g myself?
I'll be hooking it up to car tonight when I go out and see if it turns off after that.
I dunno. Just got my phone today and I went from 4G to 1x. Its quite irritating.
Yeah, there's network issues today all over. I just lost 4g about 40 min ago and this time it is still turned on on my phone.
Here's another thread about that: http://forum.xda-developers.com/showthread.php?t=1380438
Sorry your new toy can't be used to its fullest potential right when you got it, must be frustrating.

Spotty, Erratic WiFi Signal Problem - Anyone Else?

Had my One X+ for about 6 days now. Noticed that in parts of my home, had network connection issues where I never had them with any other devices. Dowloaded Wi-Fi Analyzer and SpeedTest. Downloaded SpeedTest on my old iPhone 4. And I confirmed that my phone has many more issues connecting in parts of the home than the iPhone. It's VERY erratic. You can put it on the counter 6 inches below where you were holding it with your hand, and wala, better signal. Pick it up and signal goes to crap. It's mainly with the 5.6ghz signal but 2.4 is effected to. Enabling / Disabling the Wi-Fi Performance Enhancement setting in Setting > Wi-Fi > Settings makes no difference that I can see and I compared it on and off several times using Wi-Fi Analyzer. This may be a dealbreaker for me on this phone. Maybe have to exchange it for an S3.
At times it loses connection briefly, then when it re-connects, signal is much better but it's not consistent. When running Speedtest on iPhone gauge usually goes up fairly smoothly and stays there (not always). On One X+ gauge gets "stuck" a lot more often and/or goes down.
I run an ASUS RT-56U router with latest firmware. Works excellent. It has my same network SSID bound to both 2.4 and 5.6Ghz channels. It's almost as if the One X+ has trouble dealing with a drop in the 5.6 and seamlessly moving everything to only 2.4? I actually tried to lock the phone to 2.4 or 5.6 in settings, frequency. It went crazy, both settings, it can't connecting and disconnecting.
Wondering if it is a hardware fault that was found in original One X that may have not been fixed?

If u got a problem with WiFi in certain areas of Your HOME i dont think its hardware problem. If u have a hardware problem Your WiFi couldnt recive more than "dot" signal even near router. Its because hardware issue was about antennas of WiFi (they were f****) To test hardware issue on HTC ONE X after squeze certain area of phone (antennas connected) signal growed up after release signal went down...
Looks like my hunch may be correct in that it has something to do with the phone switching between the 2.4Ghz and 5.6Ghz bands. 2.4Ghz has much better range. But in the wi-fi settings it is set to Auto frequency. What appears to be happening is that the phone prefers 5.6 but when it loses it, it switched to 2.4. I have a "dual band" N router so the same SSID is bound to both frequencies. I think this improves bandwidth for devices that communicate on both at same time (or is that not possible?) But I can't seem to get it to work if I change the frequency setting to anything but Auto. It won't authenticate when not on Auto! Bug?

I've been struggling with WiFi issues on my phone as well. Whether the phone is set to 2.4GHz, 5GHz or Auto, the connectivity is spotty at best.
With other devices in the house including my old Inspire 4g, a Kindle Fire and an iPhone I can get full reception but only 1 bar on the One X+ in spots. I have noticed that holding the phone upright in poor reception areas brings the connectivity up a bar or two usually but that's not optimal for usage... Same thing happened at the girlfriend's family's house yesterday and my connectivity was also progressively more spotty at work in the past week since getting the phone.
The screwy thing is it seems completely intermittent. It'll be fine for a few hours then suddenly the connectivity goes to crap. I'm pondering exchanging the phone for another just to see if the issues persist.
I spent much of Thanksgiving (sadly) testing the WiFi on this phone using WiFi Analyzer and speedtest at locations all over my house. I compared results with an iPhone 3GS Iphone 4 and Samsung Series 6 notebook. The One X (+) was terrible. At times it performed well but in the exact same location, the next time it would perform dismally. Very unpredictable and erratic and I found out why!
** THERE IS A 20+ dbm DROP IN SIGNAL WHEN HOLDING THE PHONE IN THE PALM OF YOUR HAND! **
Now this may be common with a lot of phones, I don't know. But, the signal strength on this phone is already not what I would describe as "Best in Class" so this drop in many areas where the signal is moderately low to very low, holding the phone in the palm usually makes a difference as to if you have a usable connection or not!
I have a highly respected ASUS RT-56U router and made sure I had the latest firmware installed, but as I said, even the iPhone 3GS had more consistent, better, even results compared to this phone in many low signal areas when I held the One X in my hand. So it's not the router, it's the device.
Next step is to try to determine if it is this one phone, the One X+ AT&T model, and the One X AT&T model, or all One X models, including International? I will head to the store to see if they will let me run the test on another phone. I'm praying it is this particular phone but my gut tells me it is probably an issue in the design of the phone. I really like this phone but may have to go for the Samsung Galaxy SIII instead as this wifi issue is BAD, and unacceptable. Would get a Nexus 4 but I need more than 16GB of memory!!!!!
I shot a video about this showing the Wifi Analyzer running:

Well, this morning I did similar testing and am seeing a 20-25 dBm drop whenever I pick the phone up...
Have you had a chance to check with your local AT&T store about testing other One X+ phones?

It would seem pointless now, since you are having the same issue, it seems to be an issue with the any One X+ (and I would bet also any One X). Maybe there's always a drop on any phone (iPhone there's no analyzer to show you signal). But this large 20-25 dBm drop make a difference between fast/normal browsing and slow/no browsing on the Net when sitting in many areas of my house. I would expect using it at other locations (on trips, etc.) it will drive me nuts. I do A LOT of browsing, use the phone like a mini tablet. So fast WiFi connectivity is paramount! I get better 4G LTE range/speeds than wifi in those areas of my house, but don't have unlimited data!
Sounds pretty simple, either u need a better router or u have a bunk phone. I have WiFi all over my house, my parents house, my work, all with zero issues and all obviously different routers. I'd maybe try another device. You have 14 days in the state's no questions asked for a new phone exchange.
It's not router. I went to AT&T store. Rep had S3. He loaded Wifi analyzer. We monitored same wifi network next shop down. HTC, signal dropped almost 20 dBM when you put it in your palm. S3, not change or 5 dBm at most. Loaded WiFi analyzer on X+ on display, but palm around it best I could around the display mount, big signal drop.
I have a large home. The thing is, no other devices have issues. What I suspect is with my home, certain areas push the HTC One X+ to its limit as far as wifi range. Most users don't notice "issues" as they don't lose a connection. And I didn't lose connection either, or rarely, just got really slow. You have to walk all around and look at WiFi Analyzer and compare holding fold to setting phone on table. Then also compare Speedtest.net app results. With S3 and notebook computer I'm getting 20mbit speeds in most areas, difficult areas, still has a consistent 6-8mbit speed. HTC One X+ those problem areas, 1mbit speeds if lucky or loss of connection.
Since nothing is changing in the test environment besides the device, the HTC clearly has poor wifi reception *RELATIVE* to other devices when held in palm of your hand. I found though you can get around this if you hold lower half of phone no issues and if you turn phone on its side, not as bad of a drop either.
I made it up to the AT&T store yesterday afternoon just to compare to another HOX+. Same thing was happening with the floor model of the phone. The manager went ahead and replaced my phone with a new one regardless just to cover our bases but like you said jazee, it does appear to be the radio location in the phone causing the issue. Just have to be conscientious of how I hold the phone.
To compensate I cranked up the TX power on my router a little bit which has helped. I run dd-wrt on it though so I have that option. Not sure what your firmware gives you access to in your Asus router. I have heard Padavan's custom firmware is a good option if you want to do more than what the stock firmware gives you access to.

I spent much of Thanksgiving (sadly) testing the WiFi on this phone using WiFi Analyzer and speedtest at locations all over my house. I compared results with an iPhone 3GS Iphone 4 and Samsung Series 6 notebook. The One X (+) was terrible. At times it performed well but in the exact same location, the next time it would perform dismally. Very unpredictable and erratic and I found out why!
** THERE IS A 20+ dbm DROP IN SIGNAL WHEN HOLDING THE PHONE IN THE PALM OF YOUR HAND! **

I get a similar drop, but more along the lines of 10 dbm.
Try keepalive from playstore

Same WiFi issue
I'm having the same issue as jazee (OP). I browse on my WiFi and then when I click on a link, I just hold the phone in my fingertips (not palm) and the signal jumps up and page loads.
Assuming olorolo's on to something here and there is an app to fix it... I'm heading to the play store to see what I can find like "Keepalive" as recommended. This is my first foray into Android though, so I can't help but wonder if you guys are already ahead of me. Any luck yet fellas?
Yes if you hold phone below volume rocker, or sideways, or even in palm with right instead of left hand, you can mostly mitigate the signal drop.
I'm happier on S3 except having to go back to ICS 4.0.4 and wait for JB 4.1. No wifi issues, much better battery usage, and no could pegged at times by Beats trying to scan my 2800 mp3 files in the background for some reason. Could tell as HTC gets HOT and then battery plummets. Brand new phone. Maybe some issues to work out?
Oh and I love having 2GB Ram for multitasking better. Would have hot S3 initially if I realized US ver had 2GB ram like new Nexus 4.

Looks like a case helps

I just so happened to have got my case in the mail today -- Ballistic SG -- and with it the WiFi drop is much less (more like 10dBm). I kept scanning with WiFi Analytics and no matter how I held it in my hands, I could never reproduce the -80dBm I was getting, no case, in the palm of my hand in the exact same spot.
For what it's worth anyway, it seems like the half centimeter of case is helping. I never would have noticed if I bought the case on day 1.
