When the screen is lit, instead of swiping the screen to unlock, you can perform the unlock gesture by waving your hand over the screen.
Unlocking without touching on Vivo Y53 is done as follows:
Step 1: Go to 'Settings' and select 'Smart motion control.'

Select 'Smart motion control'.
Step 2: Choose 'Touchless operation'.

Choose 'Touchless operation'.
Step 3: Turn on 'Touchless unlock'.

Enable 'Touchless unlock'.
That completes your setup process. Wishing you all success.
