Maybe its Huawei
My daughters Huawei tablet used to eat MicroSD cards regularly. The card would be marked as defective somehow. There's a kill bit that makes the MicroSD card read-only so you can retrieve the existing files, but nothing I found can change it back to read-write.
I put this down to the fact that I had the tablet set to shutdown each night and restart in the morning to save battery. I thought that perhaps the card was not being unmounted before the OS shutdown. Unlikely I know, I turned off the scheduled task, same behavior. Cards lasted a week or a month, it was totally random.
BTW I discovered that SanDisks "lifetime" warranty involved submitted serial numbers etc. to an open ticket, before they ask you to ship the card back to the US!
I'm assuming they know no one will go through that faff. By the time I was asked to return the card, it had got lost somewhere in the house.
I also discovered that Huawei tablets, like most other android slabs rarely get software updates to fix this stuff.
