Samsung Galaxy: How to Set 60Hz or 120Hz for Any App

Quick summary: By default, Motion smoothness on Samsung Galaxy phones is set to Adaptive, which runs at up to 120Hz most of the time. Setting it to Standard drops the whole phone to 60Hz. But you can also pick individual apps to run at 60Hz and save battery, using Samsung’s Good Lock app.

Step by step

1. Open the Galaxy Store and search for Good Lock. Install it if you don’t already have it, then open it.
2. Find the Display Assistant module in the list (the order varies) and tap the download button. On a foldable you may need to tap it again on the next screen.
3. Open Display Assistant and tap Standard refresh rate apps.
4. Tap the plus sign. You’ll see a list of your apps. Pick an app that doesn’t need 120Hz (I picked the call screen app), then tap Add. Repeat for as many apps as you want.
5. That’s it. It starts working right away. When I opened the AMC Theatres app, it ran at 60Hz and still felt smooth, while using less battery.

Remove an app from the list

Long press the app and tap Remove at the bottom, or tap the three dots, tap Remove, and pick the app. It goes back to running at 120Hz.

Other Display Assistant extras

While you’re in there, you’ll also find options to keep the screen on for 30 minutes (longer than Samsung normally allows), a brightness limit profile, faster adaptive brightness changes (up to 4x), and a screen curtain mode that saves battery when the phone is running for a long time without you looking at it.
