Just recently I have ben trying to acess my external usb micro card to back up my phone. It uused to work all day long but for some reason it's now saying can not acess the mass storage usb device. Why **bleep** is going on? Is this some kind of way to make people upgrade? How do I access my phone back up?

Check the card for a lock switch . Also check the cable if its a power cable it won't work with the otg adapter or card reader
