ok, problem solved
double tap on the screen does switch the camera, it wasn't my tablet's problem.
------------- .
on snapchat, the camera switch button in the top right corner.
while i was using it, i was only tapping the middle of the screen, the camera instantly switched. i thought that i have gone crazy, because i didn't touch the camera button on the top right corner at all.
so i tapped it a few more times, each time, the camera kept switching back and forth.
does that mean something is wrong with the app itself or something is wrong with my tablet again? !
