I have Samsung Galaxy M12 on stock Android 12. When I'm reading about Samsung features on the internet (including -related questions here), sometimes I found that I don't have such features on my phone, like Secure Folder.

What are the possible reasons for the lack of features?


1 Answer 1


There are at least 4 possible reasons:

  • Device model
  • One UI Core
  • Android Go
  • Android versions

Device Model

Newer Samsung phones and tablets tend to have more features despite having the same Android version (One UI version). Example:

One UI Core

One UI is Samsung's customization on Android OS available since Android 9 Pie for the Samsung Galaxy series. While it packs many additional features outside of AOSP, there is also One UI Core, the stripped-down version of One UI usually found on budget models such as Galaxy M and A series.

Some known missing features:

Android Go

Android Go is an Android variant optimized for devices with low memory spec. Although not Samsung-specific, some features may be disabled:

  • Notification Access
  • Do not Disturb
  • Picture-in-picture
  • VR helper services
  • Zen mode

Android versions

Android versions also affect which features are available on the device, although this is also not really Samsung-specific. (Since there are too many differences, please refer to Wikipedia for the summary of each version)

  • Possible addition: Notification history (One UI Core? Device Model?)
