YI Dashcam freezes on power-plug off

[mantullis]

Hi,
I got a cam and saw the problem after few drives. When its ON for more than 10minutes (no matter with card or without) and power is pluged off, timer for switch off ca 10s, goes and Cam freezes. No more reaction to cable plug in/out, just can be switched off with power off button.

If cam is on less time, it works perfect with power on/off.
FW reflashed, also tried to drain battery till it wont switch off but nothing.

Thanks!
