When I do a call sometimes after a few seconds the screen goes off and I can not revive it until the call is terminated. No button responds.This makes that it cannot cut the call or select sound elections of an automatic answering machine .
I try to make update, but the answer is: your device has been modified. Spftware updates are not avaiable
Thks for your help.
