Can the black screen of the front camera of Apple 8 phone be turned off?

1, the running memory is not enough, the system can't respond, and the black screen restarts or crashes.

2. Some programs will inhibit the system, causing the production system to restart or run slowly.

3. It may be cell phone poisoning.

4. It may be the virtual welding of the cpu motherboard of the mobile phone.

Second, the solution:

1. Check whether the camera is blocked.

2. If you use a third-party camera software, I suggest you take photos with your own camera function to see if there is a black screen.

3. If the camera doesn't work, please turn off the phone and restart it.

4. If you still can't take photos normally, it is recommended to back up the information (contacts, text messages, photos, etc.). ) and try to restore the factory settings.

If the problem still exists, it is recommended to take the mobile phone, purchase invoice and maintenance card to the local after-sales service center for testing.

Common troubleshooting of mobile phones:

Fault symptoms: the camera of the mobile phone is blurred.

First, the lens is dirty.

The lens glass on the back of the mobile phone is easily stained by fingers or other things. If not cleaned in time, these stains will seriously affect the quality and clarity of the picture, resulting in blurred photos.

Solution: wipe the lens with glasses cloth and wipe off the stains.

Second, the focus.

If the focus is not accurate, the picture will be blurred.

Solution: When the auto-focus of the mobile phone can't focus on the subject to be photographed, you can tap the position of the subject on the screen of the mobile phone to realize manual focusing.

Third, the lens jitter.

When taking pictures, press the camera button, the phone is unstable or the lens is shaking. The photos taken in this way are not clear either.

Solution: Keep your hands steady when taking pictures. If necessary, you can put your mobile phone on it with the help of stable objects (such as tables, stones, trees, etc.). ) to maintain stability. Of course, it is also a good choice to buy a tripod for your mobile phone.
