System Ui has stopped

[Prime10182]

So... my phone was acting normal then all of a sudden! There was the Error “Unfortunately System Ui has stopped working” then the background is black, pitch black  then I try restart my phone then it keeps coming up. So I rebooted it to safe mode then it’s fine and I even deleted third party apps. If you can provide a new system update ASAP then that would be great. I also use PlayStation and I love it.

Hi there, if the device is performing fine and the message is just appearing every since in a while , you can try these steps:

• Disable all accessibility features.
• Block notifications from apps that generate the message System UI has stopped.
• Restart your Xperia device.

If the device can't be used normally after the message System UI has stopped has appeared, you can try the safe mode again and clearing cache and data and force stop for the system UI app , i believe that will solve the issue.
