I have a no-name Chinese tablet. When first purchased, I took three pics and everything seemed fine. The problem is when I went to use the camera later and it requested I to insert or mount an SD Card. Gallery would say no pictures. Application Manager would not move apps to the SD card.
I reformatted the SD card and everything worked for 10 minutes taking pictures. Gallery would show taken pics. Application manager would move apps to SD card. Then bam, everything back to "Please insert SD card". In Application Manager, tapping on an application/Move to SD card would not work. Camera asks for SD card to be inserted, Downloaded apps from Google Play would not install asking for an SD card.
I emailed the problem and was told by Factory to Format Nand and so I did. Things work for a while then back to the same thing, "please insert SD card". Apps won't download or move. Reformatting Nand erases Gallery and many downloaded apps so I lose all my pictures and programs.
Does anybody have any ideas?
