System version - 21.1.46peregrine_retgb_retgball.en.GB retgb
Build number - KXB21.14-L1.46
MicroSD Card - SanDisk Ultra 64 GB XC I Class 10
I formatted the card on my Windows 7 pc with FAT32. It is recognised by the phone and I can use it normally. But every time phone battery dies, I get the message that the SD card is blank. It gives me an option to format the card. I get the message - Erasing the card. The card is then usable. Its file system is listed as Generic hierarchical. It has Used Space 76.0 KB and Free Space 59.3 GB. It also has 2 directories - Android and LOST.DIR.
This has happened about 3 times now and results in losing all files on SD Card. Has anyone else experienced this and any opinions as to what can be causing this?
