Z5 Dual, hangs severely after 7.1 update!

[Ali28]

Hello fellow SONY users.

I have updated my Sony Xperia z5 Dual to 7.1.1 last week and it worked pretty well for a day or two. Battery consumption is better now.

BUT!!!

Unfortunately, this happiness didn't last long. After two days my phone suddenly hanged severely and even home screen disapeared (Xperia launcher). The phone became extremely slow so that none of the applications worked.

I tried software repair via my PC again. It became good again. but after a 24-hour working with my phone, this problem happened again. Although by restarting the phone the phone become stable but after a day, it will hang again!

I tried uninstalling some applications as well to see whether the problem exist or not, but that didn't help.

I don't know what causes the problem to the phone. I hope Sony make a further update available soon to solve this problem.

Thanks.

Forget the previous suggestion. Phone is back to being slow and hot after a couple of hours.

I had same issue. Booted to safe mode (hold power button, then long press on power off).  Safe mode worked fine.  I noticed several apps updated (like 10).  Some for scrolling and crashing issues.  I rebooted to normal mode and it's great again. So something in cache cleared with the safe mode reboot or one of the apps was causing it.  But it's good now, so see if it works good in safe mode.

Did the safe mode reboot, then normal reboot and my z5c is back to normal. Thanks tx99!

For how long? Is it good now?

你好，  

我上個星期更新後的問題，就是如果我要刪除我的文件夾中的圖片，我不能。只有重啟手機後，圖片才會被刪除。我該怎麼做才能恢復正常。請救救我

Hello there,
My last week after the update is that if I want to delete the pictures in my folder, I can not. The image will only be deleted if the phone is restarted. What can I do to get back to normal? Please save me

How are you trying to delete the files?

Same problem here. This is HORRIBLE !

At least I'm not alone, my Z5C starts heating up, crashing and "eating" the battery after the 7.1.1.

Hope Sony respect the users and correct the problem, taking in account that z phones are the flagships 

In addition does anybody knows how to workaround this situation?

Same again here. Phone hanging severely after the 7.1.1 update. Only temporary solution is to restart the phone. I suspect its a RAM issue, but I'm not savvy enough to know what the solution is. 

Any long term fixes would be greatly appreciated.
