Questions about Transcend DrivePro 250 incl. 32GB microSDHC TLC

Is the resolution really only Full HD? Transcend's official site says "2K QHD 1440P": https://www.transcend-info.com/product/dashcam/drivepro-250 However, I'm not 100% sure if this is exactly the same model or if I'm seeing something else incorrectly.

After a few days, I always get the error "Memory card error", which only goes away when I format the card. Does anyone know why this is happening?

I have the Transcend DrivePro 250 and am very enthusiastic about it. Unfortunately, however, it is not possible to film after Hixntexn. Can the 250 be upgraded to the 620 (which still has the rear cam)?

If I have the cam connected in the car and it always runs when the engine is on, the battery is empty after 1-2 days. I.e. it takes some energy from the battery during the recording time until it is empty (instead of the battery being charged). Consequence: when the battery is empty, the device switches off directly (crashes) and creates an unreadable file until the card is full of unreadable files and no more data can be saved. Has anyone had similar experiences? I am curious about your experiences. Peter Saxer

Does the camera record continuously and save the films or only as in Germany? Data protection when you press the button or in the event of a collision everything else is deleted again
