There is an issue with the SD card holder/mechanism. On some screens, it will not read the SD card I put in (even though the same SD card will work on other screens). Sometimes I can hear an audible short happening when I attempt to initialize the SD card in the firmware - it creates a high-pitched whine from the SD card holder and intensifies if I press down on the holder.
I am experiencing this problem with about 20% of the screens that I was shipped (and one of the screens was cracked out of the box)!
Do you have protocols for fixing the micro SD card holder? Furthermore, a lot of SD cards (Sandisk, Samsung, Kingston) simply have problems reading. I have some experience with micro SD card holders and these spring loaded ones that are on the screens really suck. But since they are already there, what do you suggest I do to salvage the units that I already have?
Thank you.
