Weird mobile data probleme - Xperia Z2 Q&A, Help & Troubleshooting

Hi guys,
I have a Sony Xperia Z2 that just got back from repair yesterday. Running on 5.1.1 now.
Ever since I got it back I have a really weird problem with my mobile data. Wifi works fine, everything that requires internet loads, downloads, runs very smoothly. On mobile data, however, only whatsapp and instagram seem to work. All other apps such as facebook, playstore, chrome, maps etc. do not work. I have already used sony pc companion repair, in vain. I've done both a soft and hard reset and I already checked with my provider today (it is not my sim card as everything works fine when I insert it into another device).
The phone is still under warranty and I wish to keep it this way so I would rather not root it. I just got my phone back after 2 weeks of repair and I really can't miss it for such a long period again .
Any tips and/or help would be much appreciated. I hope I have been specific enough. If not, please do not hesitate to ask me for details so I can ellaborate.

I got a problem with mobile data too on 5.1.1 here is the problem, too lazy to write it.

[Q] Google Account not working?

Hi everyone, I've searched the whole XDA, and couldn't find a straight answer for my issue, so I'm asking for your precious help.
About a week ago, I was downloading an app from Market, but the phone went beserk, and died on me.
I rebooted it, but it stop giving me access to Market / Internet.
I reflashed to stock Rom, stock kernel, you name it, I did it...
Installed various Rom's and still, no dice..
Created a new account, it logged on, but as soon as I rebooted the phone, same thing
I have a Huawei U8510, so I changed my SIM card to see if it was something with the x10MP, and voilá, I can access Market with my account with no problems...
What the hell is wrong with my Mini???
I swear to God I'm gonna make a brick out of him and smash it onto some wall...
Thanks!
BUMP
Sorry, but I'm really desperate!
I had similar issue... couldn't log into my gmail account.
Then I reset the phone from the configuration menu.
Then it didn't work...
This tests were sometimes with the sim, sometimes without it, allways with wifi
Then I traveled to another country, tested it again and started working...
But, avoided the screen turning off during the google login.

[Q] Lost my latest software version, how to get it back

Hi, I've been trying to sort this out for the last 24 hours with no luck and need it fixed quite urgently
I have a Sony Ericsson Play, android version 2.3.4.
The microphone on my phone is rather strange, I can call people no problem, they hear me no problem but if i try and record my voice with a voice recorder there's absolute silence. This led me to backing up all my data and restoring my phone to factory settings hoping it was a glitch that would go away - it didn't.
So i reset my phone and it seems like it has been reset to a previous update to what I had before. I'm unsure of what update I had previously but one thing that has changed is that I no longer have the Google Play store but have the rubbish old market with hardly anything on it. Also my phone doesn't detect any of the apps that are stored on my SD (they're still there the space is taken). This is rather frustrating as I use apps such as Whatsapp a lot and I'm unable to use it.
Another major factor in my issue is that I bought my phone in the UK, had the updates done there and I am now in China. I plugged in my phone and tried updating it using the Sony Companion software but it tells me this is the most recent update (which it isn't). Same thing on the phone when I try and update it in the settings. I tried using a VPN on both my phone and laptop and 'locating myself' in the UK but it still says this is the latest update.
Can anyone offer any solution or advice that could help me regain what I had before. I've been searching all over the internet trying to find a solution with no luck.
Thanks for any help anyone can offer I really appreciate. Any questions just ask. Step by step solution would be excellent

[Q] Unfortunately,android.process.acore has stopped

Hi guys,
This is my first post.
I just got a Sony Z2, and yesterday I updated it to latest firmware 17.1.1.A.0.402 using flashtool. After that, everytime when I switch off my phone and turn it on, the message of "...android.process.acore has stopped" appeared.
I tried to flashed the phone again using PC Companion to re-update the same firmware. I though the error message has gone but than it is still there.
I have tried several ways as mentioned in this forum but the problem seem to be there. I don't see any problem/error caused by this error message yet.
Any idea/solution to completely remove the message?
Go into settings > apps > all apps, clear all data for anything relating to contacts then all will be fine, make sure contacts are backed up tho of course

Update: It happened again when I reboot my phone today. Is it possible a firmware bug?
I should wait for the next release, hope Sony will fix this issue.
Regards,
I'm on romaur which is 402 and haven't seen this error since I wiped contacts data so not sure, you still on stock or?

I also have the same issue as the OP. It particularly happened after I upgraded to .402 using PC companion.The message will appear always after restarting. My devices has not been rooted. Tried to clear data and cache for contact apps, but after restarting, the message appeared again. I am still lazy to do a re-install because aside from the message appearing only after a restart, there are no other major effect to my Z2's performance. but clearing it will be nice though.
I have the same thing when i touch the phone immediatly when it just restarted, but when i restart and leave it untill screen goes off i don't get the message.

Hi guys,
Thank you for your info.
I tried to disable contact sync of Viber and I think the message has temporarily gone. Sometimes it still pop up but not as often as before I disabled the contact sync of Viber.
Apparently, this problem is caused by contact synchronisation between Viber, Facebook, Messenger, Whatsapp, etc. Other users, such as Samsung phone users, reported that they have the same issue but when they turned off contact sync of the above-mentioned apps, the error message somehow has gone.
To be honest, I have just recently switched to android from iPhone, and I have been usings iOS for years and never seen any kind of issue/error like this on iOS. However, Sony Z2 is one of the greatest phone I ever owned and I am so happy with it, specially its crazy battery life.
Hope you guys will share your solution here if someone can fix it permanently.
Cheers,

Nope, running original stock firmware. No jailbreak/root.

Update 13.06.2014: Guys, I have tried and flashed my Z2 with UK .402 and so far so good, I dont see that error message pop-up again after reboot.
Regards,
possible fix
i had this problem, amongst others stopping my phone. i pulled the sim card out, then rebooted the phone. the phone then showed it was updating all apps i let it boot up and it seemed to work. pulled battery and put sim card back in. and all ok so far. i have sent my phone 3 times away to vodafone for this repair, with android.clock stopping, android.phone stopped working and the phone actually crashing on the samsung screen and not even booting up. each time all they do is a factory reset. like duhhhh, i have never thought of that (sarcasm). i am hoping that doing this, will give my phone some sort of permanency in it's repair. i have not rooted the phone, it is stock.
Vodofone refused to replace the handset even though it had been in so many times for repair. word of advice. steer clear of vodafone. i am cancelling all my contracts with them.
sorry that went off topic, but i want a phone that works and vodafone will not help you in that matter.

Xperia's have unremovable batteries, maybe you should steer clear of Samsungs
Is that a good thing or a bad thing though? Cos sometimes taking a battery out is what could be needed to fix a problem.
But point taken. Perhaps a change of manufacturer would help

I know people who advocated pulling the battery from devices as the only answer but I've yet to come across a situation on any device which couldn't be handled with >adb reboot or a three finger reset.
There's actually a method on Xperia devices, to disconnect the battery and plug it back. It's called "Hard Reset". Yeah you don't take the battery out in reality, but this method does it in Matrix dimension. So, the consequences are the same.

Its there a Gps tracker app that cant be uninstalled?

Hey thanks for reading, a couple of days ago , my wifes phone got stolen, i had the find my phone app installed in it but i always had my doubts as i always thought that if someone like me finds a phone and wants to keep it, they could just master reset it and erase any gps traking apps and have a new phone rigth? well thats what happened,tiefh turned off the phone right away and the phone never showed up neither on google device manager nor the find my phone either. Anyway , a person that works on a cell repair shop told me, he has his phone setup in a way that if you do a factory reset or even if you flash the phone, once the phone has acces to the internet, it will install the gps back again and tell you where it is.
So i was wondering if anyone has any idea wich app or how to do such thing. Thanks for your time and pardon my bad grammar and english.
PS: i wonder why google dosnt have something like the icloud where you can lock your phone to it via imei, that way if it gets stolen you can just lock your phone and tiefs wont be able to use it. I know google has my last imei, so i guess is posible for them to track my device to see wich other account is using my phone.

With root access Avast Mobile Security has this kind of features as far as I remember. It keeps a protection after a factory reset or a firmware installation.
BTW Apple produces the devices so they have a control on the IMEI (IMEI is a hardware data and not software). Moreover you should probably be able to contact your local authoritizies to blacklist the IMEI.
Hope it helps.
ill give that atry, the reviews dont look good but most of them look to be because people dont understand that there are 2 kinds of the same app, one for normal users , the other for rooted users. Thanks alot for your help. Any other options out there?

Thanks in advance.:crying::crying:

this sounds like a framework issue
try repairing your device via sony pc companion
Also, I tried using the pc companion to repair the phone. It started working much better till I installed whatsapp again, that the freezing started again. Is there any way to know what is causing the problem? Any suggestions on how to tweak the software to prevent it from occuring once again. Please advice

It seems that nobody else has come with such an issue or it's relatively new that nobody has an answer to, yet!!
Could you let me know, if possible, whether a sim card would have anything to do with this issue? I contacted the service centre and they asked me to change my sim card and check. As I have also mentioned that I have already tried repairing the phone using PC companion. Any suggestions/advices are welcome.
Thanks...
