When you install a custom ROM on your Android device sometimes you have to face a really annoying error and that is “Unfortunately com.Android.system UI has Stopped”. If you’re getting this error as well then now you are wondering how to fix this error. One thing is for sure that this error only comes in Rooted devices so what you have to do is to access the ClockWork Mod Recovery CWM of your Android device and Wipe the Cache Partition. Once you have done this, go to the Advanced Section and “Wipe Dalvik Cache” as well. Clearing Dalvik Cache is not mandatory but we still recommend to do it. Once you cleared both, Reboot your Android device.
That’s it. You won’t face this error again. If you have any questions feel free to ask in the comments.
