Hello,

I am facing a problem with my HCL Me U1 tablet. Suddenly it started to give this error: “Unfortunately, the System UI has Stopped”.

I have trying formatting the tab. Even wiping the internal storage and factory reset. Still doesn’t work.

Last app installed was whatsapp.

Android Version: 4.0.3

Help.
