How to Force & Lock 90Hz/120Hz Refresh Rate on Android (No Root Required)

High refresh rate displays (90Hz, 120Hz, and beyond) are now standard across most modern Android smartphones. However, many OEM skins (including Xiaomi HyperOS/MIUI, Samsung OneUI, Realme UI, and ColorOS) aggressively throttle display panels back to 60Hz whenever you launch media apps like YouTube, TikTok, Facebook, Google Maps, or select mobile games to conserve battery life. This jarring fluctuation between fluid animations and sluggish scrolling creates an unpleasant visual experience. This tutorial provides a verified, step-by-step guide to force and lock 90Hz or 120Hz globally across every installed application without requiring root access.

1. Refresh Rate Dynamics: 60Hz vs. 90Hz vs. 120Hz

Refresh rate represents how many individual frames a screen can draw per second. The differences in responsiveness and battery draw are clearly measurable:

2. Download SetEdit & Device Configuration Tools

You can acquire the verified SetEdit system database editor directly through the official repository below:

3. Method 1: Tweak via SetEdit (Android 11 & Older)

This straightforward approach functions on devices where custom system table permissions remain accessible without specialized ADB elevation:

1. Launch the SetEdit app on your device.
2. Ensure the top-right table selector is configured to System Table.
3. Tap + Add new setting located at the top of the parameter list.
4. Create the following three entries sequentially, specifying your preferred refresh rate (e.g., 120 or 90) for each:

peak_refresh_rate -> 120 (or 90)user_refresh_rate -> 120 (or 90)min_refresh_rate -> 120 (or 90)

Realme / OPPO Note: On select ColorOS and Realme UI iterations, assigning a value of 1 to peak_refresh_rate permanently forces the panel into maximum refresh mode across all third-party software.

4. Method 2: Wireless Debugging ADB Commands (Android 11 to Android 14+)

Modern Android versions enforce tighter security models that prevent unprivileged apps from editing the system table directly. You can quickly bypass this restriction using native Wireless Debugging via tools like LADB, Brevent, or Shizuku:

1. Navigate to Settings > Developer Options > enable Wireless Debugging.
2. Use split-screen multitasking: open the Wireless Debugging pairing dialog on one half, and your on-device ADB shell (e.g., LADB) on the other to pair via port and 6-digit code.
3. Once paired, execute the following shell commands sequentially:

settings put system peak_refresh_rate 120.0settings put system user_refresh_rate 120.0settings put system min_refresh_rate 120.0

For Xiaomi and Redmi smartphones running HyperOS or MIUI, execute this single targeted command instead:

settings put system user_refresh_rate 120

6. Reverting Changes & Troubleshooting

• How to Restore Stock Defaults: Open Settings > Display > Refresh Rate and toggle the selection back to Adaptive or standard 60Hz. This resets all modified system table values back to OEM factory profiles.
• Handling Reboots on Strict ROMs: If your vendor skin restores 60Hz after a reboot, use automation utilities such as MacroDroid or Tasker to automatically dispatch the wireless ADB command upon device boot.
