Dear Admin,
The camera app on my Tecno P9 just disappeared. Before this, i couldn't find the switch camera button; only the front facing camera was working, so I did 'Factory data reset' and then the camera app just disappeared for good. Installing camera apps from the store (Camera 360) did not solve the back camera issue. I would like to flash the device with the android 4.4.4 kit kat ROM and see if the issue is resolved.
Thank you in anticipation.
