Fixing The Phone’s Brightness Problems
If you observe abnormal behavior with your Android phone’s brightness, here are a few things you can do to fix it. These tips can resolve your device’s annoying brightness problems.
So, without further ado, let’s get started!
- Check Brightness Settings/Disable Automatic Brightness Adjustment
- Perform a “Soft Reset” on Your Phone
- Use Other Apps to Control Your Phone’s Brightness
- Troubleshoot Your Brightness Problems
1. Check Brightness Settings/Disable Automatic Brightness Adjustment.
If you haven’t checked the brightness settings of your phone, do so. Otherwise, proceed to step 2.
Sometimes, the culprit behind your phone’s brightness going down by itself is the built-in automatic brightness adjustment. In some phones, it’s called Adaptive Brightness, Auto-Adjust, Automatic Brightness, or Auto-Dim.
Go to your phone Settings, look for the Display options, and check if it is enabled. If it is enabled, disable it.
Additional Tips:
- Try to disable the battery saving mode on your device. This feature is another feature that can cause brightness problems with your Android phone.
- In some devices (like ASUS Phones), this option is found within the Customized Settings.
2. Perform a “Soft Reset” on Your Phone.
Whenever I encounter an issue with my phone, the first thing I do is restart my phone. This simple method is like a first-aid for smartphones.
Most of the time, restarting the phone could potentially fix most phone problems. Press and hold the power button of your phone and select “Power Off.” If you see with a “Restart” option, select that instead.
Additional Tips:
- If restarting the phone does not work, Do a power cycle on your phone. To do Power Cycle, remove the battery of your phone, then press and hold the power button for at least 10 seconds.
- If the battery of your phone is unremovable, fully deplete the battery of your phone. Once fully depleted, do not charge the phone. Power it up by pressing and holding the power button five times before turning it on.

3. Use Other Apps to Control Your Phone’s Brightness
If your default brightness slider setting can’t get the job done, use a different app to do the job. You have a few different options at your disposal, but I recommend trying Lux Lite.
Lux gives you more device brightness control than the built-in settings of Android. If the issue behind the brightness of your device is due to the stock setting, Lux will eliminate and also fix android brightness problems caused by it.
To learn more about this app, you can download and install it by clicking the Google Play button below.
4. Troubleshoot Your Brightness Problems
If everything else fails to fix the brightness issue of your device, then the problem could be more severe. To rule out the root cause, follow these troubleshooting steps.
If the problem persists after following the steps above, then it is most likely a hardware issue. I highly recommend checking for the device’s warranty and where you purchased your Android phone for repairs. If you’re not familiar with your phone’s hardware, please do not pry open your phone to try and fix android brightness problem yourself. You could potentially do more harm to your phone.
In most cases, the only way to fix android brightness for hardware problems is to replace it with brand new working parts. In this case, replacing the display LCD could be the solution.
If you have no idea or experience in doing this and want to give it a try, I recommend watching videos on how to pry open and replace parts of your specific phone model. Type “Screen Replacement” on Google, followed by your phone’s exact model.
Before anything else, if you’re going down this path of fixing and replacing the LCD panel by yourself, ensure you have the proper tools needed. I highly recommend iFixit Pro Tech Toolkit.
The iFixit Pro Tech Toolkit includes:
- 64 pcs Bit Driver Kit
- Anti-Static Wrist Strap
- Small Suction Cup
- Opening Tool and Picks
- Tweezers
- Spudgers
- Jimmy
- Magnetic Pad
- Tool Roll
- Nylon Bag
