Auto loop not working

[bipen tamang]

Its been around a month dash cam is working well and good except AUTO LOOP function, I am using Samsung Evo Plus class -10 Grade-3 64gb Memory card 100 mbps speed, inspite of using high speed card, once it get full dash cam keeps on saying "Memory card slow speed" what does this even mean??? and immediately stop recording. and after reformatting the memory card its starts working again, i have done this process twice. Any suggestion to fix this issue.

It happens if you test your 64Gb card with tool H2testw, and warns you that one MB missing in your card!
