What is the reason why Xiaomi 10s is not so smooth?

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 data, contacts, text messages, photos, etc. In the device, and try to restore the factory settings. If the problem still exists after the above operation, it is recommended that you take the machine, purchase invoice and warranty card to the local after-sales service center for testing.
