Xperia XZ Rebooting automatically

[Pencil_]

I have an issue about rebooting automatically. Even if while not using phone, my xperia xz reboots him. Also, i tried to repair my phone via companion and hardformat too. My problem continues. Moreover, I gave the phone to service 2 times and they said there was no problem (or they wasn't able to find it). The problem still continues although i sent it repair 2 times :(. Help me for fixing this problem please.

Thank You

Hi @Pencil_, welcome to our community!

I'm so sorry to hear about your phone.

How often do these restart occur, is a few times per day or once a week?

Since the service centre didn't find any faults with the phone and you have performed a software repair, I'd recommend that you remove your SIM and/or SD card(s) from your phone and see if these restarts still occur since a defect SIM and or SD card can cause the phone to restart.

I would also like to know if you restored a backup immediately after you performed the software repair and when you got the phone back from service or did you try using the phone for a while without restoring a backup?

If you did and the phone still restarts after removing the SIM and/or SD cards, try performing a new software repair using Xperia Companion. You can create a new backup before starting with the repair, but don't restore it or install any applications in the phone after the repair has been finished > use the phone as you would normally do and check if it continues to restart.

Let me know if that helps!

Although i treid all the software solutions you mentioned above my phone restarts a few times per day. Sometimes phone restarts 7 or 8 time in a day. However, I won't tried SIM card removal for solution. Thus, i will try it and observe it whether restarting continues or not. I will reply this topic if the restarts occurs altough SIM removed. If the restarts don't occur in a week, i will accept it as a solution. Thank you.

Hi again!

That sounds like a great idea!

I really hope that everything will work out for you so you can enjoy your phone without it restarting!

Hello,

This the 2nd day of my observation and for this day i observed two times my Xperia XZ restart him

My problem still continues. I think the problem is about hardware problem. In addition, although i tried all of these you mentioned above, it still continues. Help me please

Hope Android 7.1.1 is coming sooooon

As you can see in the video, my phone restarts automatically. not only watching video or stream but also it restarts him anytime while doing or not doing anything. I will go 3rd time to service and will want it to change due to my warranty. That's the proof:

Hi @Pencil_,

I'm so sorry to hear about that.

I wish I could help you any further, but since you have done everything I can recommend you doing I'm afraid that the phone has to be sent to service again.

Be as precise as you can in the error description since this is the only thing the technician can go on when examining your phone.

Keep me posted!

@fetch93, sorry to hear about your phone.

Are you doing anything specific in your phone when these restarts occur? Such as using a specific application or service? If you are, check if the application is updated to the latest version, if it is try uninstalling it and use the phone as normal for a week and see if you experience the same behaviour.

You can also restart your phone in safe mode and see if the same restarts occur here as well. I understand that having the phone in safe mode for over a week isn't ideal.

Let me know how it goes!

i can't exactly say which app was in the background. I just know that the phone was in standby and then it restarts. But this is like I say once a week or two. I have only apps on my phone from playstore and always on the latest version. 

And I found a bug.  sometimes also once a week or two Bluetooth starts itself.

Did you know when android 7.1.1 or 7.1.2 comes to the xz?
