Disable the Assistant Touch

Apart from the auto-lock, the other method you can use on your iPhone is sensitive touch. It ensures your device can recognize slower touches faster.

If it has an issue, this can also affect the functionality of other features. If the auto-lock function is not working appropriately, you should disable it.

Simply open the accessibility menu and turn off the sensitive touch.

Step 2. Wherever required, you should provide the passcode for the lock button.

Revise All Settings on Your Phone

If any of the above methods don’t work, you should reset the settings on your device. Once you do this, everything will be set to default. You don’t have to worry that your data will get lost.
