please tell me what to do now?
@ybhatt05 Is there an error that you receive? Maybe you can share a screenshot?
As you can see in the screen shot, the same error message comes for rear camera.
In short no recording from both cameras.
And no other applications activated which uses camera.
Then what's wrong with it??
Have you also tried clearing data for camera app?
What is left for you to try is a software repair using Xperia Companion. This totally looks like a software issue.
