Refresh Rate
Switch your screen between 60, 90 and 120 Hz with a single tap.

Refresh Rate is a root app for Android that lets you control the display refresh rate with one tap. It reads the rates your panel actually supports, so it isn't tied to a specific device.

Compatibility

ROM	Status
AOSP and AOSP-based ROMs	✅ Works
HyperOS / MIUI	⚠️ Untested
Other OEM ROMs (One UI, ColorOS, etc.)	⚠️ Untested

Tested on a Poco F5 running an AOSP ROM. On OEM ROMs the system may ignore or override the chosen rate. If you try it on one, please open an issue with the result.

Features

• Fixed rates: 60, 90 or 120 Hz, depending on what the panel supports.
• Dynamic mode: the system moves between the lowest and highest rate as needed.
• Quick Settings tile: shows the active rate on its icon and cycles through rates on each tap.
• Battery saver aware: shows when battery saver is capping the rate, both in the app and on the tile.
• Reapply on boot: restores your last choice after a restart.
• Force via SurfaceFlinger (experimental): locks the mode directly in the compositor when the system keeps switching it back.
• English and Portuguese (Brazil), with per-app language on Android 13+.
• Material You, light/dark theme and themed icon.

Requirements

• Android 12 or newer
• Root (Magisk, KernelSU or APatch)

Installation

1. Download the latest APK from Releases.
2. Install and open it.
3. Grant root access when your root manager asks.
4. (Optional) Edit Quick Settings and add the Refresh rate tile.

How it works

The app runs commands through su and writes the AOSP refresh rate keys:

settings put system min_refresh_rate  <hz>
settings put system peak_refresh_rate <hz>

It also writes user_refresh_rate, a key used by some OEM ROMs. AOSP ignores it; it's there for compatibility, with no guarantee it works.

With Force via SurfaceFlinger enabled, it also sends:

service call SurfaceFlinger 1035 i32 <mode index>

This is an internal, undocumented call. It lasts until reboot and only applies to fixed rates.

Building

GitHub Actions builds the APK on every push to main. To publish a release, create a v* tag (or a release with a new v* tag on GitHub):

git tag v1.1 && git push origin v1.1

Signing uses a keystore stored in the repository Secrets:

Secret	Content
KEYSTORE_BASE64	Base64-encoded .jks keystore
KEYSTORE_PASSWORD	Keystore password
KEY_ALIAS	Key alias
KEY_PASSWORD	Key password

Without these Secrets, main builds are signed with the debug key and tag builds fail, so no release is ever published with the wrong signature.

To build locally with the Android SDK installed:

gradle assembleRelease
