I've tried many different things to delete my SMS/MMS messages but nothing has worked. Things I've tried so far
tried deleting them manually one by one.
and I tried creating an Android app and getting the following line to execute
mContext.getContentResolver().delete(Uri.parse("content://sms/"), null, null);
But no method was successful. Are there any other options worth a try? I don't want to do a factory reset or root my phone.
