I have a problem.
I have a ThL W200 with android 4.4.2.
I can do phone calls, I can receive and send SMS but can not receive incoming calls.
When somebody calls me I see the call ( in status bar: the phone does not ring ), the process "com.android.phone" crash, I miss the call, then appears the notification of "changed SIM card".
I tried to reboot, to clear "phone.apk" data, nothing changed
The problem is not connected to the new ROM, because I have it since 2 weeks ago.
I think I changed some system app's permissions or deleted an important system apk
I have not a recent CWM backup so if I restore an old backup I'll certanly fix the problem, but I'll lose many apps.
Is there something "fast" that I can do? Like replacing a system app or changing permission?
Sorry for my english but it's not my first language
