Instead of swiping the screen to unlock when it lights up, you can simply wave your hand over the screen to unlock.
Unlocking without touching on Vivo Y55s 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.
