Depending on the ambient light, the OnePlus Open adjusts the level of brightness of the display. It dims down in low light ambient light to avoid blasting your eyes with huge amounts of light. The brightness automatically dials up in situations where there’s more ambient light, and it goes to its absolute maximum under direct sunlight to ensure maximum visibility.

The process is a combination of hardware and software; it uses the ambient light sensor to adjust the brightness accordingly. However, the OnePlus Open, a new foldable phone from OnePlus, has a problem with this feature. The phone is a very competitive offering despite some display issues. Luckily, we can easily fix issues with automatic brightness.
It’s not functioning properly, and it dials up the brightness unnecessarily or erratically, or it refuses to dim down at times.
There are a few reasons as to why this may not work well. If adaptive brightness is off on your device, then the feature may break. If you use the Night Mode (Blue light filter) or Reading Mode, this causes issues with auto brightness as well since the color calibration for those modes is different. The same applies if you have the dim mode on.
How to fix the brightness issue on the OnePlus Open
1: Restart your OnePlus Open
Restarting your phone ensures that the entire operating system boots from scratch. It clears unnecessary background tasks and makes way for a smoother experience. Trivial as it may seem, we recommend a basic device restart before trying the other methods. This could easily solve the issue. If there’s a communication issue between the ambient light sensor and the software, a restart could fix that. Restarting fixes all sorts of temporary problems, too.
To restart, you have to just press and hold the power button and tap on restart in the menu. Now, check whether the auto brightness is working.
2: Reset Adaptive Brightness from Device Health
- Open the Settings app on your phone.
- Tap on the “See all” option to view all apps.
- Now, tap on “Device Health Services.” You’ll find this at the bottom of the page.
- Pick the Storage and Cache option.
- Tap on Clear Storage. You’ll also find an option to Reset Adaptive Brightness.
3: Re-enable the Adaptive Brightness feature
- Open the Settings and find the Display submenu.
- You’ll find the Adaptive Brightness option in the menu at the top.
- Disable the Adaptive Brightness toggle.
- Wait for a few seconds.
- Enable the toggle again and wait for a few seconds. Test whether your adaptive brightness feature is working now.
4: Update the software of your OnePlus Open to fix the brightness issue
OnePlus consistently pushes out software updates to the OnePlus Open. This ensures that the software continues running smoothly and is up-to-date with the newest security patches. Software updates also squash multiple bugs in the software. There were a lot at the time of launch. If there are problems with auto brightness on your phone, ensure that it’s on the latest software.
Open the Settings app and tap on the System option. Now, select the System Updates option. Update your phone from here if there’s a new update available.
5: Reset your OnePlus Open to factory settings to fix brightness issues
This is only an extreme solution that we recommend if the problem is persistent after trying all other solutions. This will wipe all the data on your phone, including your apps and photos, contacts, etc, so ensure that you have a proper backup of your essential data. This option is not recommended if you don’t mind manually adjusting the brightness until a fix is out.
- Open the Settings app on your phone and tap on the Additional Settings option.
- Tap on the Backup and Reset option and then select the Reset Phone option at the bottom.
- Tap on Erase all data and confirm the factory data reset. It’ll take a while to erase the phone, and it should restart on its own.
