Got my A500 for a week now, but now I have run into a problem I haven´t seen before. Let´s say I delite a file, or install an app. but when I turn OFF the A500 and then ON again, all the deleted files are back and the istalled app. are also gone. Only the apps installed before a specific date are still there. Have tryed a Hardware reset, but not working. Even tryed a factory data reset, but it´s all there when i turn the A500 on again. Anybody had theis issue, or know what to do??
