Tribalfs edited this page Aug 26, 2025 · 5 revisions

Starting OneUI6.0 (Android14), installing/updating the app requires doing it using ADB or an advanced apk installer.

Using a PC:

Execute the adb command:

adb install --bypass-low-target-sdk-block [path to the apk file]

Example:

adb install --bypass-low-target-sdk-block "C:\Users\tribalfs\Downloads\galaxy_max_hz_v8.1.apk"

with the apk file located at C:\Users\tribalfs\Downloads\galaxy_max_hz_v8.1.apk.

If you have no ADB tool setup yet, follow steps 1 to 6 of How to grant WRITE_SECURE_SETTINGS, which you will also need to do after installing the app.

Without using a PC:

Option 1: You may install and use Install with Options app - with Bypass Low Target SDK block option enabled - to install Galaxy MaxHz.

Option 2: Using LADB to execute

adb install --bypass-low-target-sdk-block /sdcard/galaxy_max_hz_v8.1.apk

with the apk located in the root of your device internal storage. You have to follow LADB's setup guide to enter adb shell (not non-adb shell). Move the downloaded gmh apk file to the root of your device internal storage and execute the above provided ADB command. Setting up LADB will sometimes require a few attempts to be make it pair successfully. Rebooting the device maybe needed. Video walkthrough

Google play protect warning when installing

Google play protect may prompt warning like this or this when installing the app for the first time due to the app's usage of old sdk, you can just ignore it and click "More details" and "Install Anyway". Please check FAQ #1 for the related info/explanation and privacy related concern.**

After install and or after OS update, you may need to allow restricted settings

You may also need to "Allow restricted settings" to the app. You need this if some Galaxy MaxHz settings won't stick and won't work properly. Open Settings > Apps > Galaxy MaxHz > Click top right menu and Allow restricted settings. Menu will be hidden once done. If you haven't done it yet but the menu is not shown, go to Settings > Accessibility and turn on > Galaxy MaxHz. It should show a prompt that you have to allow restricted settings first. Then check again if the menu is already shown.
