Xperia Z3 Tablet LTE Android 5.0.2, build 23.1.a.1.28. Crashing

Hi Forum Mates,

I bought my Xperia Z3 Tablet LTE 1 month ago. It keeps on crashing when it should not.

I contacted their support in Germany 19.08 vial onlne emails (bought it in Germany and I live in Germany) but their support has not replied me yet.

Yesterday I contacted them again but no replies. I really wonder how come their service ceter takes such a long time to respond cusotmer´s emails. What is the Sony service level agreement?

Here are the details -

It got the newest Android 5.0.2, build 23.1.a.1.28.

The tablet suddenly turns off and then restart without warning or showing messages. I checked "Diagnostics" - System Incidents, in the last 10 days it happend 9 times that it crashed. On Sunday morning right after I got up it crashed twice when I was just reading news and Sony support site.

Today I had my lunch and went outside for a walk. After coming back, right after I activating the tablet, it got frozen and then crashed. I checked the Diagonostic in the phone and I could see that it "secretly" crashed once already. So in total twice crashing until now today.

I am very sure that my tablet has a lot of power (usually 80% - 90%) when it crashed.

1. I play games often on the tablet, but usually during the gaming it does NOT restart. But if I just take it out and read webpage, then it restarts in front of my eyes immediately.

I read the online help articles and I cleared the phone and app cache because I thought maybe it is because of other apps. But it did not solve the issue.

2. I restore the phone with "Factory data reset" and only installed very basic apps from Sony, plus Spotify, VLC players and Hearthstone game. I did NOT install more app. But then when I watch Youtube, the phone turns off automatically. It happens really frequently. So I unstalled Youtube updates from the phone.

3. I turned off Stamina service because I worry that maybe the battery app made the issue. But still it happens.

4. I saved app only on Sony internal memory and I only use the external SD card for backup purpose, no movies and no photos on it.

5. I did NOT allow my apps to upgrade automatically from Google store because I worry that upgrading automatically could cause the problem. So I update my apps manually.

6. I also removed the "Android Web Viewer" on Sunday since I read that it could cause crashing. But it did not solve the issue.

Do you have the similar issues or solutions? Suggestoins are appreciated.

Thank you very much!

If you didn't already try this: I'd suggest that you do a PC Companion phone repair, this will do a clean installation of the latest firmware and will also wipe your internal memory. It's totally different and yields better results that Factory reset.

Open PC companion -> Support zone -> Phone/tablet software update -> Repair my phone/tablet (blue link style). Follow the steps given, do not connect your phone until prompted to press volume down while plugging USB cable.

Hello @Quester,

Update here -

The issue got worse now.

After using the PC Companion, it was better in July and August but still the tablet crashed often. I was not too bothered cos sometims I just restarted it. But since October it got much worse.

Last Friday 16.10 I used the PC Companion again to reinstall the system. But since Friday to today (19.10), it crashed already 10 times. Before it did not crash so frequently.

I also de-activated many apps such as Sony "What is new", and "Sony Lounge" because I had thought they might cause the issue. I also did not use "Stamina" mode but still the system crashes.

The tablet runs the newest version 23.4.a.1.232 (Android 5.1.1). Previously it did not crash when I played games. But now it crashes in the middle of my game.

I called the Germany´s support and I was told to contact their support again via writing so they could collect my device and repaire it.

Thanks!
