In the restless world of Android customization, where users chase every extra frame per second, a curious tool has surfaced: Refresh Rate Changer 30 by RC Modz. The name alone sounds like forbidden fruit for mobile gamers and performance tweakers. But what exactly is it, and should you even think about installing it?

Let’s dive in.

Key Features of Refresh Rate Changer 30 by RC Modz

Before diving into the Refresh Rate Changer 30 by RC Modz APK install, let’s explore what makes this tool stand out: refresh rate changer 30 by rc modz apk install

  1. Manual Refresh Rate Control – Force your display to 30Hz, 48Hz, 60Hz, 90Hz, or 120Hz depending on your device’s hardware.
  2. Per-App Profiles – Set specific refresh rates for individual apps (e.g., 30Hz for YouTube, 120Hz for Call of Duty Mobile).
  3. ADB-Free Operation – Many refresh rate changers require a PC and ADB commands. This modded APK bypasses that for rooted or vulnerable devices.
  4. Overclock Capabilities – On select devices, it can push the refresh rate beyond factory limits (use with caution).
  5. Battery Saver Mode – Automatically switch to 30Hz when battery drops below 15%.

These features make it a favorite among power users and mobile gamers who want granular control without digging into system files.

How to uninstall or revert changes

  • Disable any overlays or accessibility permissions first.
  • Revoke root/ADB permissions if you granted them for the app.
  • Uninstall the APK via Settings → Apps → Uninstall.
  • Reboot device.
  • If refresh rate was changed via settings, revert with: adb shell settings delete system peak_refresh_rate adb shell settings delete system min_refresh_rate or reset display settings in Developer options.

Alternatives to Consider

Before sideloading an obscure APK, try these safer options: Unlocking Smoothness or Rolling the Dice

  • Built-in Battery Saver – Most Android phones already lower refresh rate to 60Hz in battery saver mode. Some (like Samsung) offer a “Standard” 60Hz mode in settings.
  • Galaxy Max Hz (for Samsung) – A well-known, safer app that allows dynamic 48Hz–120Hz control without forcing unstable 30Hz.
  • AutoHz (Root only) – For rooted users, this is the gold standard for per-app refresh rate control.
  • SetEdit (Settings Database Editor) – A more transparent, open-source tool to manually edit refresh rate values (requires careful reading).

Using an App (If Supported):

  1. Install Magisk Manager (if you haven't already). Magisk is a systemless rooting solution that allows you to modify system files without actually modifying them.
  2. Find and Install an Xposed Module or a specific app like FPSMeter or SetXFrameRate that can change the refresh rate. Some modules in the Xposed Framework allow you to do this.
    • Open Magisk Manager, go to the menu, select "Downloads" or "Modules," and look for anything related to refresh rate or frame rate modification.

Step 4: Configure the App

  1. Open the Refresh Rate Changer app.
  2. Grant any necessary permissions (such as "Display over other apps" or accessibility permissions) for the app to function correctly.
  3. Select your desired refresh rate (e.g., 90Hz or 120Hz) and tap Apply.
  4. Launch your game to see if the smoothness has improved.

Installation steps (general APK side-loading)

  1. Backup device and important data.
  2. Enable installation from unknown sources for the installer app (Settings → Apps → choose browser/file manager → Install unknown apps).
  3. Download the APK from the source to your device.
  4. Open the APK file and follow install prompts.
  5. Open the app and grant any requested permissions (Accessibility, overlay, or ADB/root as required).
  6. If the app requires ADB, connect device to PC and run recommended commands from the developer (typically via: adb shell or adb shell pm grant ...). Follow developer instructions precisely.
  7. Reboot if requested.

How Does It Work? (The Technical Side)

Modern Android phones (especially those with LTPO displays like the Samsung Galaxy S23 Ultra, OnePlus 11, or Pixel 7 Pro) already have dynamic refresh rates. But many mid-range or older high-refresh phones only switch between 60Hz and 120Hz. They can’t go down to 30Hz natively.

This APK uses Android’s hidden developer options and system APIs to override the default refresh rate behavior. Specifically, it: Manual Refresh Rate Control – Force your display

  1. Accesses the SurfaceFlinger service (which manages screen composition).
  2. Modifies the peak_refresh_rate and min_refresh_rate properties.
  3. Forces the display driver to accept 30Hz as a valid mode, even if the manufacturer didn’t enable it in the stock UI.

When successful, the phone’s display physically refreshes 30 times per second. Scrolling becomes choppy, but the GPU, CPU, and display panel consume significantly less power.
