Have you ever try opening your android phone camera and it giving a error saying "Can't Connect To Camera", This has happen to so many people especially you want to snap in a public place and it giving you this type of error. It is frustrating though.
Scroll down to Camera and tap on it
STEP 3 (Three) - ROOT REQUIRED
>> Download Camera Fix CM Apk – Playstore>> Launch the app and tap on Restart camera to fix the issue. (Root needed).
I am sure, the problem will be fixed. In some case, If cleared Camera data, force stopped it and rebooted the device. The error might disappeared after that.
Kindly comment and share.
