I bought a new XOLO Q1000s 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 apps, but they only show the front camera. When I tried to shift the camera in the camera 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 flashlight, even though my mobile has one.
