I bought a 70mai Mini Dash Cam in January 2021. The camera has been working correctly for 1 or 2 months, however after this period it keeps shutting down after 1h of recording. I tried different SD cards (Samsung class 10 32 GB, 128 GB), but it doesn't make any difference. I also tried plugging it into a charger at home, without or with the SD card, but with no luck. The camera still turns off after 1h and starts recording instantly after I press the power button again.
It's not a big deal for me, hence I'd rather not send the camera back to the retailer, as they'd take months to process it. I've also read here that a GPS module could cause the problem, but I don't have one.
Any suggestions on what could cause such a problem?
