When I'm using apk manager, android status, and other application that show storage status... they detect my external storage is 1,36Gb.. I tried to plug 8Gb SD card. Cek again, that all application still detect my external storage is 1,36Gb. But if I go to setting > SD & Device Storage.. my haipad detect my 8Gb SD card. anyone know why? the other strange.. when I connect M701-R to PC, I got 4 removable disk..? it should be only 2 right? (the internal storage and SD card) please help me..
