com.android.phone stopped in new phone

[Macris1]

Hi I Just got a new L1 and every now and then I got the error notification "com.android.phone - close app", the phone signal dissapear, the connection is over and then recorvers almost inmediatly. This problem appear both using an app that requires Internet or when I'm not even using my phone. I already restart the phone to fabric, changed the sim card and checked the APV configuración.  Could it be a problem with the phone,  the software update or anything else?

Try to perform a software repair using Xperia Companion. This will do a clean installation of the latest firmware and will also wipe your internal memory. Don't forget to backup using Xperia Companion, but preferably without adding apps or settings to the backup.

Follow the steps given in blue links, and keep us updated.

Hi and thanks for the quick response. Unfortunately after I did the repair the problem isn't solved. When I turned on the phone,  just in the configuration (5 minutes) I got the same message of error. The only thing I still doubt is about the permission for the Cell Info, I gave the permission and that notification still appear on the notification menu. I am from Chile and don't know if it's ok for this to appear.
