Samsung is bringing an important set of security features and quality-of-life improvements to a couple of smartphones. The update is dubbed AltZLife and is only available on the Galaxy A51 and A71 smartphones in India. Some of these features will probably be made available on other smartphones as well, but AltZLife in its entirety has been specifically designed for the Indian market.As the title says, one of the major features included in the update is the so-called “ultimate private mode.” It’s a neat feature that lets Samsung smartphone users to quickly switch between normal and private mode by simply double-clicking on the power key. But that’s not all that the private mode does.

For example, you’ll be able to switch from the normal Gallery to a private Gallery on the fly. The same goes for apps like WhatsApp or Messenger where you can switch to private modes with a simple double click. All private versions of these apps are secured by Samsung Knox in the Secure Folder of these phones.
