I'm using moto e for over a year now. my since the last few months this error "SD card removed Unexpectedly" keeps popping up. It happens everytime when I charge my phone or connect it to USB, play specific songs or randomly too. Everytime this happens I have to eject it and insert the card again but since yesterday even when I do that within a minute or so the error pops up. Finally giving up Isearched about it on the internet I found out that it happens if i use a Class 10 SD card and if I switch to a Class 4 or 6 the problem would go away. But then I checked my SD card class it's class 4. I am using a SanDisk 8gb class 4 card. and I tried this with another car which is also class 4 8gb, sandisk. But the problem still prevails. Please help me out.
