Isn’t it annoying when the brightness of the display of your Android smartphone fluctuates or changes inconsistently? By default, the brightness settings of your phone will automatically adjust depending on the level of light in the current environment. If the current environment where your phone is exposed is bright then the brightness will be low and if your surrounding is too dark, the brightness will ramp up.
If your brightness settings are flying all over the place, or it keeps dimming even when set to max, then there’s a problem that needs to be fixed. If you’re already at your wit’s end, then don’t worry, we’ve got a few things and workaround for you to try to get your brightness problem sorted out.
Some of these methods change from device to device, so don’t worry if all the steps here don’t apply to you. Follow all of the steps you can until you either get to the end, or your brightness problem is fixed. If you don’t have a hardware problem creating the issue, your screen will be fixed before you’re done reading.
How to Fix Phone Display Brightness Problems?
If the brightness of your phone exhibits abnormal behavior, here are a few things you can do to fix it regardless if the problem is brightness to low, going down by itself or water damages.
Check Brightness Settings / Disable Automatic Brightness Adjust
If you haven’t checked the brightness settings of your phone, do it now. Otherwise, proceed to step 2.
Sometimes, the culprit behind your phone’s brightness going down by itself is the built-in brightness automatic adjustment. In some phones, it’s called Adaptive Brightness, Auto-Adjust, Automatic Brightness, or Auto-Dim.
To ensure that this is not the culprit, go to your phones device settings. Proceed to the display option and check if it is enabled. If it is enabled, disable it.
- Also, ensure that the battery saving mode is not enabled on your device, it’s another possible culprit that causes this issue to save battery life.
- In some devices, like ASUS Phones, this option is found within the Customized Settings.
Perform Phone Soft/Quick Reset
Whenever we encounter an issue with our phone, the first best thing to do is to restart the phone. This is like a first-aid for smartphones. Most of the time, restarting the phone could potentially fix most phone problems.
To do this, simply press and hold the power button of your phone and select “Power Off“. If you are presented with a “Restart” option, select that instead.
- If restarting the phone did not work, give Power Cycle a try. 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 and power it up by pressing and holding the power button. Keep doing this for 5 more times. After that, charge your phone and power it up. See if it fixed the issue.
Control Brightness with Other Apps
If your default brightness slider and settings aren’t getting the job done, using a different app might do the job. You have a few different options at your disposal, but we 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 brightness problems caused by it.

Troubleshooting 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 basic troubleshooting steps.
If by the end of that guide the problem still persists, then you’re out of luck. At this point, it could potentially be a hardware issue. DO NOT pry open your phone to try and fix the problem yourself. You could potentially do more harm than fix it. We highly recommend consulting the device warranty, and where you purchased your Android phone, for repairs.
In most cases, the only fix 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, we recommend watching videos on how to pry open and replaced parts of your specific phone model. Simply type on Google “Screen Replacement” without the quote followed by your phones exact model. Example, screen replacement Samsung S5. Google will provide helpful articles and video guides to help you out.
But before anything else, if you’re really going down this path of fixing and replacing the LCD panel by yourself, ensure you have the proper tools needed. We highly recommend iFixit Pro Tech Toolkit.
