When I power off my lumia 535 it reboots with a gear and bolt sign
I am getting a thunderbolt and gear sign when I reboot my phone. I have to to a soft reset everytime to bypass this issue. There is no sound when somebody calls my phone. I can see the call appearing in display but without any ringtone. Please suggest.
