Cant't connect to the camera.Please make sure to close other apps that may use camera or flashlight.
I have try to close and reboot the phone but still same problem occur
Please advice. TQ.
I suggest you to flash the ROM of your phone with SP Flash Tool choosing the 'Firmware Upgrade' option. http://community.umidigi.com/for ... peid%26typeid%3D162
If that doesn't help, then your phone should be disassembled to check the connection of the camera to the motherboard. However if you want to keep your warranty valid or can't manage that, you should return your phone to your reseller for a replacement.
Well, you just didn't say that you got this error with 3rd party apps, not with the stock camera app.
This issue is known (already discussed in some other threads) and the developers are working on it. We're waiting for the update.
