High Brightness Mode

Can’t see your screen in the bright sunshine?

This app triggers an extra high brightness mode that is built in to many phones with AMOLED screens, including most Samsung, Motorola and OnePlus phones. See below for a list of devices with high brightness mode (HBM) capability.

Even if your phone does not have the special HBM hardware setting, this app will force maximum screen brightness, which is really handy when you are outside in the sun.

HBM does not require root on Samsung devices, but the screen can will be brighter if your device is rooted. With root, this app can force maximum brightness beyond what is available in system settings.

HBM now requires root on OnePlus devices!

HBM requires root on the Nexus 6/6P, Pixel, Pixel XL, Pixel 2 and Motorola phones. Root is required because HBM is a special hardware setting, it does NOT simply increase your brightness slider to max. This is significantly brighter than max brightness on compatible devices.

Four ways to activate high brightness mode:
-Auto mode, which turns high brightness mode on or off depending on ambient lighting
-Widget for your homescreen
-Quick Settings tile (Android Nougat or later)
-Manually in the app
