So, I have a weird problem with my Xperia SP. I've used 5 different sd cards already, and each of them has died on me. After a week or two, my phone just says 'SD card unexpectedly removed' while the card is still there, and can't detect it anymore. The cards also don't work on my pc with a card reader and on a different phone, so I'm pretty sure they are dead. I understand that microSD card do die, but it happens very often to me since I have this phone so I think it is to blame. What can I do? I'm on .205 stock and unrooted.
