Xperia Z Ultra reboots continuously

[howden82]

Hi, I have had my Xperia Z Ultra just short of 2 weeks, last sunday night my phone started shutting its self down, and then instantly restarting, doing this every five minutes. Since then i have done a repair via the desktop sync app, and i have done a full complete factory reset. Both times have temporarily solved the issue.

But last night (sunday night again) it has started doing it again, restarting every five minutes, the back of the phone feels warmer than usual, the boot loop seems to be drinking the battery as well.

The device is on the latest version of the operating system.

Thanks,

Stephen

It's a facebook app compatability problem. Uninstall facebook and probably instagramm too. I've uninstalled the facebook just now and it worked. This thread helped me actually: https://forum.xda-developers.com/xperia-z-ultra/help/responding-restarting-t3624404
