FAQ

Does akiHz require root?

No. akiHz uses Shizuku to access the refresh-rate-related system settings that ordinary Android apps cannot change directly. You still need to start Shizuku after restarting your phone, but you do not need to unlock the bootloader, install Magisk, or modify the system partition.

Why does Shizuku need to be running?

Android restricts access to the settings akiHz needs. Shizuku provides a local, permission-controlled bridge to those settings through wireless debugging or ADB. akiHz asks for authorization through Shizuku and does not receive unrestricted root access.

Will it work on my phone?

akiHz detects the rates reported by your display and includes strategies for several Android manufacturers. It has only been personally tested on a Xiaomi phone, however, so other devices are not guaranteed. If automatic detection chooses the wrong settings, you can try the OEM override or create a custom profile.

Where can I get help or report a problem?

akiHz is a personal project provided as-is, without a support commitment. The repository is not accepting support requests, bug reports, compatibility requests, or feature requests. The complete source is public under the MIT License, so you can inspect it, fork it, and adapt it for your device.
