Recently files in my sd card disappear when I restart the phone. This happened on kitkat and lollipop now. I have Sdfix installed and didn't have the problem before. Also this happened with 2 sd cards so I think its an Android problem. Anyone having same issue?
I lost some photos from my sd card too, but I think it is because of Clean Master... Have you got Clean Master on your phone? I've got kk on my padfone a86.
No I don't have CleanMaster or any other program. It also happens when I put files from the PC onto the SD card. Even when I use a card reader to put files on it are gone when I put the card in the phone. All the files that have been on the card are still accessable. Only any new files I put on it are gone after a while, definately after a reboot.
I had the same problem with a Sandisk 64GB microSDXC card. I could write data to the card when it was in my phone or on my PC. But removing the card (after unmounting or using safe removal!) and putting it back again showed that no new data was there. Unfortunately this happened when I had already bought another bigger 128GB Sandisk card. I am just waiting for this to happen with this card too. After this I avoid buying any more flash memory made by Sandisk.
