Doesnt switch cameras

My Rear Camera is broken and the live cast directly goes the broken camera and when i try to switch cameras to the front selfie camera i keep tapping but it doesnt switch, i tried going to settings but nothing, i hope you find a fix for this. Until then, im only gonna rate it 2 Stars
