stock camera app missing and front camera reported as rear camera in xolo q1000s I bought a new xolo q 1000s recently, and I made sure to test the back camera before buying it. After four or five days, when I tried to use the camera for the first time, it shows only the front camera; there is no option anywhere to shift to the back camera. 

I tried installing other camera apps to get the back camera, but that didn't work. I then did a factory reset, but after that, the camera app itself went missing.

My phone is not rooted, but I no longer have a built-in camera app. I can install other camera pps, but they shows only front camera. When I tried to shift camera in cymera app, it said you have no front camera! And yet it shows the front camera, and doesn't use the back one. Similarly, when trying a flashlight app, it says I have no flash light, even though my mobile has one.
Actually I think it is a hard ware issue. I have had issues like that and never knew what the problem was until one day I had a broken screen and took the phone to the repairer. After changing the screen , i realised that the rear camera wasn't working ( I've never had a problem with camera on that device ) . I took the phone back to him and he just readjusted the camera cords or ...( I don't know the technical term for cables ) and it was working just fine .
