What if Samsung c7 always cuts off many screens automatically?

There is an automatic screen capture phenomenon on the mobile phone. I suggest you:

1. Check whether third-party screen capture software is installed and try to uninstall it.

2. Check whether the screen capture function is turned on in other third software, such as the screen capture function of shaking the mobile phone in QQ.

3. Back up data (contacts, text messages, photos, etc. ) and try to restore the factory settings.

4. If the problem still exists, it is suggested that you take the machine, purchase invoice and maintenance card to the local Samsung after-sales service center for testing.

The address information/customer service telephone number of Samsung service center can be inquired in the following ways: please log in to Samsung official website-click on the after-sales service in the upper right corner-click on the search for Samsung service center-select the province and city where the product type to be inquired is located on the left side of the interface, and the service center in the city can be automatically searched.

Tip: If there is no service center in your city, please contact the after-sales service centers in neighboring cities first and ask if you can check and repair by mail or express delivery.
