Depending on how I hold my phone, my external SD card keeps “unmounting” and will stop being read by my phone. How do I fix this issue? Can it be fixed?
Did you try with another SD card? If yes try clearing carefully any dust in the socket where the SD card goes in.
I have the issue too… Keeps randomly mounting and unmounting. Sd card works in other devices and new sd card does the same. Any advice?
