Hi, Am Walter from Uganda, my rear camera of my DP7CPRO isn't working? What can I do?

Walter. Try first booting into Safe Mode to test whether a third-party app is causing trouble.
If that makes no difference, you could try a different camera app from the Play Store.
If still no go, the phone may need repair, or a replacement camera module.
