The camera behind the phone sprayed alcohol. Why didn't it show up?

Alcohol has no effect on the camera. Maybe your camera is broken.

The rear camera is the camera on the back of the phone. 1. Open the phone settings, swipe down to find privacy, click Enter, and then click Camera. 2. Then check the application of the camera you want to open. 3. If it can't be solved, you can try to restart your phone. 4. If it still doesn't work, click Settings, General, Restore and Restore all settings.
