How to set up Focus Mode on a Samsung device with Android 12

Annoyingly, and you’ll run into this often as an Android user, your smartphone’s menu structure might look slightly different if it’s not using the “stock” software. In particular, Samsung runs its One UI software on top of whatever version of Android your phone is using, and it has its own version of a Focus Mode.
Head to the Settings panel on your Samsung device.
Tap Digital Wellbeing & Parental Controls.
You’ll see a tiled interface. Tap on the top one to enter Digital Wellbeing.
Scroll down the page to the category Ways to disconnect.
Select Focus mode.
You’ll notice Work time and Me time have already been populated. Tap these to edit them, or start your own.
On the next screen, Samsung will ask you to choose the apps you can access in Focus mode. For instance, the Work time setting only allows you to use the clock app, Galaxy Wear, for accessing a smartwatch, Messages, Phone, Play Store, and Settings panel.
You can add more apps to the list by tapping on the Edit option.
When you’ve finished selecting apps, tap on Duration and choose how long to enforce this particular focus profile. Choose by the hour or until you manually turn it off.
