About High Brightness Mode

1. This is significantly brighter than max brightness on compatible devices. -Most Samsung phones, including Galaxy S6/S7/S8 and Note 6/7/8. -Most Motorola phones with AMOLED screens. Requires root. -Nexus 6P, Pixel, Pixel XL, Pixel 2, Pixel 2XL, Pixel 3, Pixel 3XL, Pixel 3a, Pixel 3a XL: Requires a custom kernel such as ElementalX or Kirisakura and root.

2. 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.

3. High Brightness Mode Widget uses a hidden hardware setting to unleash the full potential of your AMOLED screen.

4. 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.

5. On phones with the HBM hardware setting, this app can make your screen up to 20% brighter than the highest brightness setting.

6. For Samsung and OnePlus phones, it is recommended to select the "Disable autobrightness when HBM is on" option if you use the system's auto brightness.

7. Root is required because HBM is a special hardware setting, it does NOT simply increase your brightness slider to max.

8. You can adjust the threshold for triggering high brightness mode and set auto mode using either the app, widget or quick settings tile.

9. HBM requires root on the Nexus 6/6P, Pixel, Pixel XL, Pixel 2 and Motorola phones.

11. This app can maintain high brightness mode even if you turn your screen off and on (and even across reboots!

High Brightness Mode Customer Insights

1. OnePlus should really reconsider not using the high brightness mode of the samsung displays they're using because folks it is a game changer regarding outdoors readability.After clicking high brightness mode slider it goes on then off and the screen is dimmer as it turns the brightness down to about 40% when off.

2. When turned off, it decreases brightness, so that it look like it does something when you turn it on again and it puts brightness back to the max level of the phone, but not any higher.Super basic app easy to follow, worked on my son's old Samsung Galaxy tab a, my TCL 10 5G and my other son's brand new Google pixel 6 which it worked on that one the best.

3. Not sure if it's any brighter (phone is not rooted) but it's nice because my screen has an issue where it won't unlock at low brightness levels, If I hit the High Brightness widget before locking or powering off, it comes back up in full brightness.Absolutely useless app taking money out of your pocket! When you turn it on, it doesn't increase brightness at all.

4. To me that spells fake app, it turns my brightness down to give the illusion its turning it up when its doing nothing at all.Makes no difference to using ordinary screen brightness settings.

5. With my Android phones, if I have the brightness turned down while indoors, the screen becomes completely unreadable when I go outdoors into bright sunlight.

6. But you can set this app so that when you turn your phone back on, the screen is set to maximum brightness.

7. You'll never have to run under a tree or go into a building's shadow, or even go back indoors, to see your screen.Since going from a Galaxy J337V with outdoor mode to an A03s with adaptive brightener, I could not see my camera screen when trying to take photos outside.

8. I can't even see the brightness slider in order to make the screen visible.

9. I think the high brightness mode of the total is simply your device's preset and not a boosted level.

10. The difficulty there was effecting yhe change in a way that would feel natural as an extension of the built-in auto brightness algorithm.

11. When i click it again yes the brightness goes up but thats because its going from 40% to the original 100%.
