What is System U I error?

[Martin1]

Hi @Tacomaruston, let me see if I can help out here.

The error message saying that "System UI has stopped" is usually generated by a downloaded app in the phone. Since it might be hard to detect which app in the phone that is generating the error message, the easiest way to get rid of the error message is to repair the software using a computer and Xperia Companion.

Keep in mind though that a software repair will erase all user data from the phone, so make sure to do a backup of your user data before the repair. 

I hope that helped!

Hi @Mehrdad7052,

System UI is a system app that controls the interface of the device. As I mentioned in my previous post, this error message is usually generated by a downloaded app in the phone. Since it might be hard to detect which app in the phone that is generating the error message, the easiest way to get rid of the error message is to repair the software using a computer and Xperia Companion.

Let me know if you have any further questions!

Attention please.

Either use Xperia companion or Google backup or other means to backup first.

You'll find a lot of information inside FAQ or Tips & Tricks or the Sonymobile section on YouTube.

Don't forget to backup messengers like WhatsApp seperately from within the app.

After repair only install the most necessary apps. Do not restore everything from the backup or you might restore the app that is the culprit as well.
