There was the Error “Unfortunately System Ui has stopped working” then the background is black, pitch black &nbsp;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.</P> Tue, 02 Mar 2021 01:23:44 GMT Prime10182 2021-03-02T01:23:44Z https://community.sony.ua/t5/z-series/system-ui-has-stopped/m-p/3779075#M123091 <P>So... my phone was acting normal then all of a sudden!
