Galaxy Max Hz Donation is a donation app designed for Samsung devices that allows users to send a donation to tribalfs on XDA for those who can't donate using PayPal. Donation will also unlock GMH's premium features on your particular device. This app is free to use and available on the Android platform.

Galaxy Max Hz primarily caters to Samsung devices, so compatibility with other brands is not guaranteed. This app offers a range of refresh rate features, allowing users to adjust the minimum and maximum refresh rates, switch between adaptive and high refresh rate mode, and configure different refresh rate settings for every application. However, these features are only available to devices with multiple refresh rates.

In addition to refresh rate features, Galaxy Max Hz also offers screen off mods, such as force lowest Hz on Screen Off/Always on Display, auto power saving mode while the screen is off, Quick-doze Mod with adjustable maintenance window interval, and auto sensors off while the screen is off (experimental). Other features include Refresh Rate Monitor with quick settings toggle, Resolution Switcher with quick settings toggle, and Tasker plugin support.

Please note that some features may not work on some devices with updated OneUI4.0+. To know more about Galaxy Max Hz, check FAQs in XDA.
