Is my Android device vulnerable to CVE-2019-2234 and How can I mitigate this before a firmware upgrade?

>**Background Info:** CVE-2019-2234 is a serious vulnerability or (maybe an APT) which allow other apps to record videos, take pictures, and extract EXIF data without having permissions. > >**Edit:** This question is other devices rather than Pixel & Samsung I've tested this PoC (changed package name to my camera's package name) to check if is this possible on my (non Pixel) device, but all I have is the camera activity has been launched without starting recording or taking pictures. **Launch Camera:** adb shell am start-activity -n com.android.camera/com.android.camera.CameraActivity --ez extra_turn_screen_on true -a android.media.action.CAMERA --ez android.intent.extra.USE_FRONTAL_CAMERA true **Launch Video:** adb shell am start-activity -n com.android.camera/com.android.camera.CameraActivity --ez extra_turn_screen_on true -a android.media.action.VIDEO_CAMERA --ez android.intent.extra.USE_FRONTAL_CAMERA true **Question** **Part 1:** If this device is vulnerable are there other extras to add to make the PoC work and proof that it's vulnerable? or just it's not? **Part 2:** If the device is vulnerable, what would be the best mitigation solution for this?
