The mobile phone is broken. What should I do if I press it and there is no response?

Because there are too many customized software in the mobile phone, it is recommended to brush the mobile phone after going to ROOT, and don't download too much software. If there is not enough ROM, the screen will get stuck.

Solution:

1. Check whether there is a film on the phone. If you have any suggestions, cancel the film on the screen and try again.

2. If the touch screen of the mobile phone is completely out of order, I suggest you restart the machine and observe it again.

3. Try to update the mobile phone system version (note: please back up the data in the device before upgrading).

4. If it is invalid, back up the data in the device (contacts, text messages, photos, etc. ) and try to restore the factory settings.

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

Maintenance method of mobile phone screen:

1, oil stain and sweat, etc.

Mobile phone screen is very afraid of conductive media such as oil stains and sweat stains, which will make the touch of mobile phone screen unresponsive or drift, so if you find oil stains, sweat stains and other substances, dry them as soon as possible.

2. Static electricity

Although the current touch screen is very hard and wear-resistant, static electricity, a very unstable factor, can easily break through the capacitive screen. Although the surface of the capacitive screen will be treated with a layer of antistatic treatment, it does not mean that it can withstand the instantaneous voltage brought by human static electricity.

3. Magnetic field

If you put a small magnet on the screen, you will soon find that the capacitive screen has a temporary fault, which will cause a permanent fault after a long time. Therefore, we should try to avoid close contact between mobile phones and speakers or other magnetic objects.
