I just buy Sony Xperia V 7 month ago. When I buy it. I use 16GB SD card with no problem..
But when I change it to Samsung 64GB SD it always keep unmountig my SD card with message "SD Card unexpected removed".. I also don't know what happen.. I already tried formatted it and it still the same.. And when I transfer data inside it.. My phone cannot read it.. When I restart my phone all my data has gone..

Hi Uliwooly,

There seems to be a lot of people complaining about Samsung 32GB cards (I also had that).

There may be overheating problems making the sd contacts loose or implemented interface protocol issues.

But only with Samsung Pro (UHS-1, Class10).

If you use other brands witth same speed (like SanDisk Ultra UHS-1, Class 10), it won't happen.

At least, this was my experience.

And there seems to be a pattern here...

Hope  this helps,

It happens to me with Sandisk 32GB. Try other memory card. I think there are problems/issues with UHS-1, Class10 memory cards. Try other memory card.

FYI,

The same error I had with Samsung UHS-1, Class 10 card happened again to me 1 month ago with the SanDisk Ultra UHS-1, Class 10 replacement card I was now using.

So, be cautious with high-speed cards...
