Fortunately I haven't seen the system ui error ever since I uninstalled substratum. Crazy how one app can cause such havoc.@squick You could try booting into safe mode to see if its a program causing it, but for me, i updated my phone software(update) with the substratum ui apk installed which caused me to get the force close error where only the screen showed system ui has stopped. I used adb to get a list of packages and remove the substratum system ui apk. A sure way to fix would be to reset the phone, but if you're able to use it, try removing apps you dont need from your applications in the settings. It's possible there could be another app interfering with the system ui
Edit: just got the error again so back to the drawing board
