Slow to recognize SIM
When I insert my SIM card, the status in the upper left corner is slow to update from No SIM to the name of the provider.
Same happens when I remove the SIM card. Then it takes a minute till the status in the upper left corner of the screen is updated to 'No SIM'.
Sometimes it won't update at all, even slowly. Then A reboot will do the trick.
I want to know what causes this and how it can be fixed since I need to resell this phone.
Any help is highly appreciated :)
