One UI

[Rathindra]

Every Smartphone brand provides App Lock feature with their OS but Samsung still lacks here . Today Every Samsung user has to download third party app for locking their App . Secure Folder is not a substitute of App Lock as many users don't use Secure folder . Samsung must provide this feature with One UI . It is users demand. 

Hope Samsung will consider this with next update.
