I use an SD card I bought to save photos from my phone and then to upload them to tablet for back up storage. The card always been read by my tablet until recently. Each time I insert it, now it doesn't get read except briefly and then acts as if the card isn't in. I tried it on my mobile again and it was read on there without a problem.
Also when I ejected the card from its slot,it shot right out into the air and I had to catch it.
Could this be more likely case of damage inside the card slot itself?
