Samsung s2 1 front camera has a leaked black screen.

If the mobile phone displays a black screen, there are many reasons, such as system problems and software conflicts. The damaged screen will be displayed as a black screen. It is recommended to try the following:

1. If the screen is always black:

Press and hold the power button for more than 10 second, and then try to turn the machine on and off again. If the fault still exists, it is recommended to send the mobile phone to the nearest service center for testing.

2. If the screen is black sometimes:

1. It is recommended to uninstall the third-party plug-ins running before the black screen.

2. Back up mobile phone data (phone book, SMS, multimedia files, etc.). ) and restore the factory settings.

There is water mist on the lens of the mobile phone, probably because there is water or moisture in it.

There is water mist on the lens of the mobile phone, which may be due to water ingress or fog before and after the camera gets wet. You should think that if your mobile phone is flooded, I suggest you don't try to turn it on to prevent internal components from being damaged due to short circuit inside the machine.

In this case, first remove the card, and then find a hair dryer to blow at the card hole to see if the fog on the camera has dispersed while blowing. If it is loose, blow it for a while and try to dry it. If this method doesn't work, we have to repair it.
