My android tablet is not working My android tablet is displaying an error message 'Unfortunately, the process com.android.phone has stopped'. The message occurs so quickly that I am unable to touch any application.
Try this:


Quickly press OK on the error dialog so you can follow the rest of the steps.
Navigate to Settings > Apps > All.
Scroll down to Phone and click it.
Clear cache for it. If the problem persists, clear data as well.


If this does not help, try clearing cache and data for the Sim Toolkit app as well.
