Memory card issue

[Hassanshakeel]

my Sony Xperia z2 SD card quit working. I tried to mount it, but after the phone states that it is preparing the SD card, nothing happens. What can I do to get my SD card working again. And then if I format the card it shows and mounts automatucally, and then again if I copy any stuff, and open apps like vlc or utorrent, the apps gets slow and then the card gets unmounted. The card is a SanDisk 64gb class 10 sdxc.

I was formatting it a couple of times but problem was still coming back.

Problem start to happen afther the update.

Before that I had no issues with SD card

Test another SD card or test your SD card with another phone.
