Sorry to hear about your issues with your device destroying your SD cards...very unusual.
I have the Samsung Galaxy Tab A also...so far, nothing like that has occurred and I think I have had it for at least 6-8 months and I fly weekly for work/fun also.
It could be a device-specific problem...I got mine from Verizon so if you did the same, could they trade out the device itself?
I will be on the lookout for this...but so far, so good.
Thanks for posting and letting us all know to beware of this. I always carry a backup tablet on longer X-C's just in case something like this were to happen...
