Hello to everybody, I am now the "happy" user of this device BV 8000 pro I am satisfied, for my use it is OK. Only I notice one fault. When I want to use the Zello app/ PTT and SOS key, and I switch the multifunction key in Settings on. The Long press of this key enters the SOS, it works. But by the short press of PTT, goes the phone to reset mode, the phone makes restart. After restart the phone reports, that cant find the SD card/or it is broken.
By another restart with power key, the phone comes to normal state.
Can you explain me why it is doing? Can I repair it?
Thanks a lot Vik
