When I try to raise the volume and I have hearphones inserted it won't allow me to raise the bar more than by half, it will show this message, screen lock the phone and reset my wallpaper. it's a pain. Upgrading android system had no effect on this issue.</P> Sun, 26 May 2019 10:46:00 GMT Aivlis87 2019-05-26T10:46:00Z https://community.sony.ba/t5/e-series/ui-has-stopped-working/m-p/3642970#M4498 <P>Keep losing wallpaper photo&nbsp;</P> Thu, 25 Apr 2019 20:31:31 GMT https://community.sony.ba/t5/e-series/ui-has-stopped-working/m-p/3642970#M4498 Teency 2019-04-25T20:31:31Z https://community.sony.ba/t5/e-series/ui-has-stopped-working/m-p/3642971#M4499 <P>How do I fix system UI has stopped working&nbsp;</P><BLOCKQUOTE><HR /><A href="https://community.sony.co.uk/t5/user/viewprofilepage/user-id/1182669">@Teency</A>&nbsp;wrote:<BR /><P>Keep losing wallpaper photo&nbsp;</P><HR /></BLOCKQUOTE> Thu, 09 May 2019 03:40:40 GMT https://community.sony.ba/t5/e-series/ui-has-stopped-working/m-p/3642971#M4499 Alias7710 2019-05-09T03:40:40Z https://community.sony.ba/t5/e-series/ui-has-stopped-working/m-p/3642972#M4500 <P>I have the same issue.
