Try settings/backup and reset/ factory reset

If you mean it is stuck in Landscape rather than Portrait mode then swipe down from the top and tap the BOX icon top left of the screen that turns the screen lock on/off

If you mean video / photo gallery then sorry, your question is too vague to answer.

hi I just got the 9" RCA tablet for my daughter birthday January 13,a friend of my order it from wal mart in December she only use it about three times which is weekend we put it to charge but would not charge what do I do it anew tablet

The battery is becoming faulty and will need to be sent in for service. A hard reset MAY help.

You'll need to do a factory reset:
1. With the device off, press and hold Volume Up and Power.
2. Release the Power button when you see the logo, but continue to hold Volume Up until the recovery screen appears.
3. Use the Volume buttons to navigate the menu and select wipe data / factory reset. Press Home to choose the selection.
4. Press Volume Up continue.

When the tablet is OFF hold volume up button then switch on all the time holding the volume up button untill it boots into reset options. use vol up and down to scroll between options then power button to select.
