Can’t see your screen in the bright sunshine?

This app is here to help! It turns your screen’s maximum brightness level up by 20%.

There are many smartphone models that have the High Brightness Mode (HBM) hardware setting built in, including Samsung, Motorola, and OnePlus phones. See below for a list of compatible devices.

Most devices with HBM hardware have two settings: Max Brightness and the maximum HBM setting. Max brightness is your normal brightness level and it can be controlled using the Android System Settings app. The HBM setting gives you an extra boost of brightness, and it can only be controlled using this app.

What is HBM?

HBM (High Brightness Mode) is a hardware setting built into the Samsung, Motorola, and OnePlus phones that allow you to turn your screen’s maximum brightness up by 20%.

It is required to use HBM and it is turned on by default.

On many phones that have HBM, the brightness cannot be changed from the settings, and even if you find the settings, you may not be able to change them.

This is not a settings app, it is an app that will let you change the HBM setting and also change the threshold for triggering HBM.

You will get the screen maximum brightness, but up to 20% more brightness on compatible devices.

How do I activate it?

It is very simple, just install this app on your phone. If you already have the app installed, you will be able to use it right away.
