I have android 9 on my xperia xz1. Since the last android January update , app camera is not working. The first time I open the app, it works well but the second time the app shows an error message that says "Error cannot start camera. Reboot cellphone". I've done factory reset and I've done software repair twice however the app keeps failing. What can I do?
If the software repair do not manage to make the camera app work as intended, I am afraid there is not much else i can recommend that you try other than having the phone examined and possibly repaired by an authorized service center
And since service routines, warranty and consumer laws may vary depending on market, I suggest that you contact your local support team for further instructions.
