There is a lag when opening an app that is locked<BR />2. The all will be in unlock state untill the screen gets off<BR />3. Masked apps are not working untill they are unmasked and also notifications are not hidden.<BR />4.It will not ask for password so anyone can easily unistall it Wed, 13 Jan 2021 09:40:05 GMT Krishna0512 2021-01-13T09:40:05Z https://r2.community.samsung.com/t5/Tech-Talk/App-lock-feature/m-p/6720947#M137414 Please provide in-built app lock feature for Samsung A71, using external apps we can do it but when Android has the feature in it i think samung should enable it.
