HELP! no signal - Xperia Z2 Q&A, Help & Troubleshooting

Hello
I got my xperia z2 D6503 2 days ago brand new sealed. I inserted my Net10 sim and it worked like 1 day and than I noticed that there was signal issue first I thought it was because of area than I found out it was phones fault since same sim card worked perfectly on my old xperia z and also on xperia z2 Tab and on my brothers galaxy s4. strange thing is it shows low signal only when LTE is on and I can send and receive text messages but I can't make calls. as soon as I turn off LTE it looses signal and no text or call go through.
I tried factory reset, 2 different sim cards, even bought new sim card, numerous restarts and nothing helps. searched web for this issue and nothing at all.
so anyone else had this experienced? any solutions?
thanks

Same issue with my z2... only when I hold it a certain way... I'm on Bell mobility in Canada and got the phone a few days ago.

I've been experiencing the same issue ever and I've had my phone over a month, I'm on EE in the uk running the .55 firmware. My phone is currently in repair to fix this problem so I'll get back to see if it can be fixed

Sony has no solution in USA and can't repair so I returned for exchange to seller. I though it was only me so looks like gonna be big issue

Hey, so did the exchange solve the problem for you? I am using NET10 as well and while I do get signal on all networks (2G. 3G, etc..) I notice that it isn't as good as almost any other phone I've had. I live in an area that has poor signal and places that I get 1-2 bars on other phones I get 0-1 on this phone, though when I'm in upper town where signal is great I get about the same as others do. I'm just not sure if my phone is defective or this is just how it is. I really don't want to wait to exchange plus the seller seems reluctant to do so..

I had to fix my APN (wireless &networks -> mobile data).
I Google the correct settings for my carrier(ATT/USA), and saved the updates and it worked IMMEDIATELY.
it's been solid since ever since. Note there are differences for the 3g VS LTE versions. Make sure you enter the right settings.
Good luck!

I got replacement toda so far so good.
yea I noticed that signal is not as strong as it was on my Xperia Z. even lost signal at the places where my Z was solid. hope this could be solved with future software update.

I did entered correct APN's as I mentioned it was working great for almost day and Than suddenly stopped working so if I had entered wrong APN's it wouldn't worked first time I powered it on. plus same sim card worked well on other LTE phone while was not working on my new Z2, so it was not APN issue.

Try rebooting 3-4 times and then wait. This should solve the problem.
Check the baseband version online and on your phone.

There is also a firmware update but you have to cable your phone to a computer and let it install the Sony software on the PC/MAC ... Mine updated yesterday...
Worth a shot if you haven't done so already.

Thanks man, it seems that's just how the phone is, maybe I can stop worrying so much about that now, especially since this Z2 I have has no defects that are so plentiful on other user's phones.
And like I said, it's not such a big deal when I'm in places with adequate coverage so it's tolerable. I updated to .402 yesterday and there isn't any change with signal but I'm holding out for more updates that can help out with coverage. I'm thinking once the Z2 is released in some way in the US (carrier or Sony store) that there will be an update then that may help us out.

I'm probably the last person to be offering advice in this forum, however, just a couple days ago I noticed I had no data connectivity at all. Calls and texting still worked, but no cellular data. All my APN setting were correct and even though airplane mode was not selected, turning it off and on again got my data connection back. Just something stumbled upon and I have no idea if it applies to anyone elses issue here. Just thought I'd toss it out there in case it helps just one person.

Solve which problem? The one i posted in very first post or the weak signal on my replacement? I did more than 5 reboots to solve first proble but nope.
Now this very weak signal worries me it loosed signal at places where my old Z was great. Hope this phone doesn't end up super problematic
Sent from my SGP521

Sony Service will service/replace the set, if needed. So please do check in there.

phone is amazing everything works smooth, but weak signal is getting on my nerves! looses signal very often and data gets really slow because of low signal even when LTE is available. I live in brooklyn ny and my xperia Z didn't have this issue at all. hopefully this could be fixed soon by software update.

Drop down quick settings from home and ensure LTE is ticked on.

Call sony xperia department let them fix it or replace new one. Don't even think phone can repair itself

Same problem
My sisters got the same problem,
Help line, Tech team no help what so ever !!!
Been on the phone for over 2 weeks !!!
They wont solve the problem what so ever !
One tech team even said "buy a new phone" !! such great customer service !!
They are wanting £150 for it so it can be "fixed"..... also wanting £40 for the month contract despite not having the phone !!!
I understand who you feel... they are no use what so ever and rude...

No Service-Hardware or Software ??

First time asking for help but I can't find the answer to my problem. I have no service on my X10, no calls, text, data. No service at all, just grey bars with a BIG X. I don't know how to tell if it's a hardware or software issue. I don't think software is the problem. I put my phone in airplane mode one night and the next morning turned back to normal mode. I noticed later I had no service. I had been running the Wolf 4.0.0 for about a month when this happened, with no problems at all. I have flashed back to 2.1 and then 2.3, no change. Searched and entered APN's for ATT. I did find some posts about "CRASHING SYSTEM SERVER" but I don't think it applies to this software. Am I missing something? I sure don't want to pay Sony $185.00 just to re-flash my X10 with a quick fix.
Any Ideas???
My setup is:
Wolf_Xperia_4.0.0
2.6.29-00054-g5101537

2.1.71

Try your simcard in a different phone to make sure the sim is working as they can sometimes die I've had a few die on me over the years without even touching the sim since it was put in the phone.

Thanks, but have a new sim fromm ATT, sorry I forgot to mention that.
No Service Issue
I have same xperia x10i with baseband .71
it had same problem few months back and it was working fine
changing sim caused the problem again
now it wont get any signal with any working sim
Is that problem hardware related or software related
FYI i have tried stock 2.3.3 cm7mod and team rom 3.8/3.9 but no service...
Help plz
Regards,
I don't know what the problem was with my phone. It started working one day and has been fine ever since. I do know that I was using the phone in a weak signal area, 1-2 bars max, before it stopped working and when it started working again I was in a full bar area. A software glitch or antenna problem, not sure. I have 2 of these phones and side by side the network radios have completely different signal profiles. The phone I was having trouble with still gets half the signal the other one gets.
Thanks

[Q] No signal at all.

Hello. I bought my Z2 about a month ago. Everything worked out well.
One day at work i noticed i have no signal at all, with the red X next to the signal bars. I thought my sim card was just loose or something
Tried other sim cards on the phone and they dont work either. The phone DOES get reception (even h+) somewhere when in town, but still with only 1 or 2 bars. (103-105dbm)
At home and at work i get no signal at all...
Tried messing with APN settings and checked them many times. Tried fiddling with airplane mode on and off.
At the moment im backuping the phone and going to try a factory reset. No hopes that it will work though.
Any ideas? The phone HAS been under a warranty screen repair because i shattered it on the first week of use (was my wife actually)
But it worked fine for many weeks after the glass repair..
Thanks!
Try resetting via flashtool or Sony PC companion
If the issue persists then send your device for a replacement
Sent from my D6503 using XDA Premium 4 mobile app
Yeah took it to the store i bought it from. Went to repair.... suprise suprise i got a message today about a delay because the device has been sent to "Sony main repair"
It's always when you explain a problem that they don't believe you.
They probably just sent it to their own repair for some dude to test their card in the phone cause they think i'm so stupid that i haven't tried that yet. Always just: "of course its fixable easy piece of cake"
Just replace my phone already......
But note all: Batch 14w19
Will be interesting to know if anyone else will get connection problems later on or not.
I never have 4G signal but thats due to firmware, same goes for my wifi... Wifi is flaky
Sony need to go back to the erricson days when they were realy competing
Their customer service is uneducated and their phones are Ok, Xperia Z/ZU was best xperias yet, most others are generaly terrible, Z2 is ok but them manufacturing errors are just bad
From pre poduction all the way to 14w23 is faulty
Fail sony

[Q] LTE not working on Z2?

So around 3 weeks ago I got a brand new unlocked Z2 D6503. As it says, it supports LTE and the bands it support are available and broadcasted here in KSA.
I'm on the operator Zain KSA and when I manually search for mobile networks, I do see the LTE network by the operator but whenever I select it, it doesn't register on it.
I've tried everything from calling/visiting the network operator from changing the SIM and getting a new one.
The FW I have is .314
Anyone has any experience or any idea? Do I need to reflash the FW?
May be enter the correct APN settings for your carrier?

Firstly, are you on an LTE plan? For Singapore, we need to sign up to an LTE plan and the operator has to do the necessary activation, before we can register on the LTE network.

That's the thing, I already had 4G activated, and I specially got it deactivated and activated again on this handset. 4G coverage is in my area, each and everything is in optimal condition. The network operator says everything is also fine at their end...

Yup everything is configured correctly
I can confirm that it is the handset that is not registering LTE.
I just popped in a working LTE SIM which has full coverage in my area and Z2 fails to register it...
Well I can't say much about LTE since I am on 3G data plan so can't use it. But the funny thing happened that I was on Edge connection, even tho I was in city centre and I could use 3G, it was full. So went into phone options and changed into 3G only and then Z2 has magically seen the better connection. Try to do that for LTE, maybe it will work. Otherwise I would flash other firmware or repair with PCC.

Okay so actually solved the issue.
I reinstalled/repaired the FW using Sony PC Companion and now LTE works perfectly. But the side effect? I heard that 4.4.2 causes many bugs and seems like I just got the phone sluggish one.
Phone feels sluggish in different parts as well as when I tap the recent icons button. Also the animation for WiFi turning on and off is not there anymore...
I don't know what's happening anymore....:/
I too have a bit of a lag when I hit recents menu button. I guess it's just the way Z2 is now and we have to wait for new firmwares, hopefully with less bugs, to come.
Happy for you that you fixed the problem with LTE

Yeah, seems like we'll just have to wait for 4.4.4 to hit...
Sad how the animations worked and there was no lag but sadly no LTE functionality. Such bad FW release.
And yeah atleast I fixed the LTE issue as I really can't stand slow internet and H+ seems pretty slow to me.
Same problem...install the new software through PC companion still the problem

[Q] Mobile network data connection drops. Why?

I have a problem with my Galaxy s6 Edge.
When browsing the web with only mobile data turned on, wether using edge/3g/lte, the mobile loses connection .
I still have connection visible in the status bar, but wepages stop recieving data and it just stays hanging, with the loading bar at the same place. It can be fine for 3-4 minutes and then start to act up again.
One sollution is to toggle data connection on/off, then it will work again, but only for a couple of minutes. My phone is unrooted. I have tried factory reset. I have tried using the different settings in mobile data; just gsm7just wcdma and wcdma/gsm- automatic etc. The signal strenght seem to be about 75-77dbma.
Do anyone have the same problem, know of a cause for this, or have possible a sollution? Please share
I've had a similar issue a few times now. No discernable cause. Solved by airplane mode toggle.
Sent from my SM-G925V using XDA Free mobile app
Yes, I will try that, but think thats about the same effect as toogling data. It helps, but the problem is still there. I sent an mail to Samsung about this issue. Hope it is software related and can be fixed. Its frustrating cause I`m reliant on stable data connection. When logging in again, the webpage has changed and i`ve lost my opportunity.

I have the same issue, and connection drop even if u you are in thetering mode(wifi/usb)
I got new mobile (replaced from vendor) and the new one have similar issue.
I try on lte/wcdma - only wcdma, with one apn and so on.... nothing to do problem is still there...
Sorry to hear that! Its a shame paying this much money and find out about these problems. This phone replaced my s4 because of the "sim card not detected-restart" error on the s4. First Samsung denied the issue. When they admitted it, I had already opened it up and exchanged the sim card reader, and lost warranty. That was not the fix.
Hope the issue will be fixed with updates. Lesson learned- Dont buy first batch of mobiles. Wait for prices to go down, and a more mature hardware.

I have the exact same issue on my s6. I can't figure out why it happens. It appears and disappears for no obvious reason. I wouldn't mind waiting for a software update to solve the problem but I can't stop wondering if I have a defective unit.
I' starting to wonder if there are network changes on the phobecausing this. The signal keeps going from H to H+. And maybe the adapter has to reset before it can download again. Just a hunch, but I have noe knowledge about what's happening.
But, if this was a widespread problem, I think more people would come forward saying they have this issue. If they don't have it, then maybe we got bad lemons, and we have too keep exchanging til we find one that works.
Its an software problem ( i guess of managing "swap" between h h+ and LTE. after 7 day of test i got the mobile replaced from mediaworld, and the new one have the same issue.
Im from italy with Vodafone, maybe all of us are vodafone.
can be interesting discover from where we are and our mobile company.

I'm using "Telenor" here in Norway. They have a 1 month deal with Samsung to be the only supplier of the edge. Tried to get internet/mms setup sent from them, but it said this wasn't available for this phone. But going to their guide, it seems everything I set up as it should.
I tried switching on the data roaming. That seems to solve the issue so far. I haven't had to switch the data on and off for more than 24 hours now. Before this I had to do it multiple times every day. I guess it's safe to say that the problem came from the software side. Let's hope that fix it in the next update. I'm using international version, though.

I just turned on the data roaming, but still on the same service. Now I can't really tell if that really did the trick. I got new firmware update just the day before yesterday and now the network drop is gone. If you haven't got any update yet maybe you just gotta wait. It's eventually fixed.

I have the same problem with a Samsung S6, AOE3. I want to return or change the phone, but I don't know if this is a software or a hardware problem....and to have the same problem with the next phone
I've got the same issue. Only airplane mode on and off helped me. But I've to do it many times during the day. I wrote a letter to Samsung and waiting their response.
Just read about roaming "on" as one of the users mentioned here, still testing.
PS I'm from Russia (on local forum many people has this problem). Hope this is software problem.
Same problem about my s6 edge mobile data connection
Still dont know what happen . I already have note series but there's nothing like this one. this make browsing much harder coz data stuck and keep hanging bout 1-2 minutes. Please make it fix ASAP . I love my s6edge
I am from Canada i have same issue plus my phone does not even have lte/gsm/wcdma option but still when i go on the *#2263# menu and put my phone to lte/wcdma it looses connection in like 5 minutes.
but still if i am connected to the internet same issue connection stops and it starts woking after a minute or so but really really frustating specially with a price tag on this phone.

Elephone S8 Weird issue with network

Hey all,
I am hoping somebody can guide me in regards to an issue I am facing.
I was working on my car a few days back and left the Elephone S8 on the car seat not realizing that it was being hit directly by the sun. After I was done, I picked up the phone and it was very very hot. I then went inside and let the phone cool off.
Since the above, I notice that I struggle to pick up reception. I have tried different firmware, replaced sim cards, everything. It seems to only be affecting certain MHZ bands as 4G LTE work, 3G works fine, and 2G works find but not always.
I have a feeling the 2G is having issues but maybe only certain bands. I do not think it is software related but have no idea where to even start on the hardware side. I first want to try scan for towers and see which bands they use and try see which one could be giving the issue. I don't expect it to just be a lose connector as the phone has not been dropped and I have only been using it for 2 weeks. If I do send it back under warranty for repairs, they will never pick up this issue.
Elephone S8 loss of network issue
Hi.
I think is a hardware issue as the same thing happened to me after 3 weeks perfect use.
I think has nothing to do with the sun as for me happened on a snowy Sunday 10th of December in London.
I suddenly noticed that when sending email the sending would start fast and after a 2-3 seconds the network will drop to 3G and stay like that for long time until the mail app stops sending process and the phone goes back to LTE 4G.
Also when dialling a number the phone will drop from 4G to 3G and than loose the connection straight away.
When indoors the phone would have trouble registering to network for ages without success.
I picked up 4 different pay as you go cards to make shure that is not my network but still no success.
All documented in the support ticket to GB and yesterday have send it back for a refund.
I really like the phone but i am reluctant to buy another if the issue persist so will wait and see.
Hope some more comments will follow to highlight the problem and influence a solution to this.
Cheers
I have the same issue - my wireless connection inside my home keeps dropping and connecting off and on again and again - I have two routers and maybe as I move from room to room it tries to connect to the closest router or something like that - not sure if there is a way to fix it without doing something in the routers.
Wifi

Same problem here
My network problems are a little different. I don't have problems connecting to different wifi networks (home and work) but the phone does not activate mobile data when leaving a wifi network. I always have to restart the phone when I want to use mobile data (3G).
Kind of the same problem. Have my S8 for about a month. First it has a wifi network. When I leave the place where it is connected to wifi, it goes to 4G. But when I come back to a place with WIFI, the phone does not find any WIFI network. I have to reboot the phone. Soft reboot(a little faster) will also do/work.
Are you guys on the stock ROM?
Were you guys able to resolve your issues

I have the same problems with stock rom and eragon rom. I don't have a solution but I'm still hoping for a new update.
For now I found out that turning flight mode on and off again helps to switch between wifi and mobile data, so it is not necessary to reboot the phone every time.
I can confirm as well that Eragon won't resolve 3G / 4G network issues.
I'm using my S8 for a week now with only one problem, call related.
No wifi problems but after one day of usage I couldn't use mobile data anymore I almost re-flashed my phone (unlocked bootloader, rooted and using Xposed). Turned out my provider f*cked things up. Probably because Elephone is a not known brand here. It took me some time to convince the agent on the phone that I do not own a Samsung S8 lol.
Problem was solved at the providers end.

This information sounds interesting. How did you manage to 'convince' the providers agent that it is not Samsung? And what did you tell it instead?
Steve the issue you have is different. Your issue won't be resolved that way.
You would need an app that switches to 3G/4G if WiFi is not connected.
Happy too soon. After one day with mobile data it's gone again. There's a cross in the lower right corner of the mobile data icon in the status bar. I'll be calling my provider again tomorrow morning.

I'm not sure if the fact that I own a brand that is unknown here causes the mobile data problems. The problems I'm running into atm are
- mobile data problems, 4G is connected, but no internet
- fingerprint scanner doesn't work with my banking app
- backlight bleed in the middle of my screen
- after 3 out of 4 calls, phone freezes for about 30 seconds
- rattle in fingerprint scanner
I guess I'm about to find out how good the return policy at Banggood is ?
I highly recommend that you return the phone now.
There are so many issues with the phone that it's just not worth the time.
Hi guys, I just got the phone, but mobile data is not working. Am I missing something?
Can you attach a screenshot

Does your sim card work in another phone? If so, are the apn settings the same?
I managed to resolve the issue.
I'm trying to figure what went wrong at start. When I got a phone I inserted both SIM cards like this:
SIM 1 - my business phone number - provider 1
SIM 2 - my personal phone number - provider 2
I wanted to use data only on my personal phone number, so I disabled data on business number. What happened is my business SIM downloaded APN info on first boot (i assume), and then my personal SIM used this APN (which was incorrect).
To resolve issue I first inserted my personal SIM to slot 1 alone and booted. Then I changed APN profile to match my old phone's, turned off phone and inserted my business SIM to slot 2 and booted.
Now data works fine. Obviously there was APN issue but how come that phone didn't get correct APN settings per SIM?
Thanks for support!
