You must have observed your Android screen’s brightness reduce by itself or even turn off when you wanted it to remain on. When you leave your phone screen unattended for a long time, the screen brightness reduces and it becomes dim. This is just one of the many reasons why your Android screen dims.
If you are looking for the answer to how to stop your Android screen from dimming, you’ve done yourself a favor by coming here. In this article, I’ve listed down the main reasons why your Android screen dims or switches off and how you can stop screen dimming due to those reasons.
So grab your Android handset and get ready to fix your screen dimming issues!
Effects of dim screen on eyes
When the screen brightness is high, the blue light emitted from the phone can be harmful to your eyes. Let’s understand this scientifically: As blue light has the shortest wavelength in the visible spectrum, it has very high energy levels.
So when you expose your eyes to high intensity blue light, it tends to damage the photoretinal cells in the eye. This in turn leads to strained eyes, headaches, and blurred vision.
However, dim or low-light conditions are equally harmful to your eyes. In dim or low light, your eyes tend to focus on the screen, causing eye strain and headaches. If your work involves more screen time, be it on the phone or laptop, it is recommended to do eye exercises regularly.
The optimum brightness level for your Android phone or tablet should be the one adjusted by the auto-brightness feature. It changes the screen brightness in response to the ambient light.
Note: The methods listed below work for most Android phones including Samsung, Redmi, LG, HTC, Oppo, and Vivo.
Why does your Android screen dim and how to stop it?
1. Inactivity for a long time
As stated above, if your Android phone or tablet screen is left unattended for a long time, the screen will fade. It has happened to me many a time–especially when I’m taking notes from an ebook and the screen goes dim or simply turns off. Here’s how to stop screen dimming due to inactivity:
How to stop screen dimming due to inactivity?
To stop your Android screen from dimming due to inactivity, you will have to change the screen timeout time.
Follow these steps.
Step 1) Open the Settings app on your Android phone
Step 2) Tap on Display
Step 3) Tap on screen timeout
Step 4) Change the time to 5 or 10 minutes as per your preference
The screen will remain on without dimming up to the time set. You can change this setting using the same steps.
2. Proximity sensor blockage
A proximity sensor is a non-contact sensor on your phone used to detect an object close to the screen. When the phone comes close to any object while on a call, including your face, it turns the screen off to prevent any accidental button presses. Check how to fix screen dimming due to proximity sensor blockage.
How to stop screen dimming due to proximity sensor blockage?
The proximity sensor is located on the top of the phone. Check if the proximity sensor is blocked by an object such as a phone case or cover. Remove any object close to the proximity sensor to avoid screen dimming.
While on a call, you can simply press the power key to turn the screen on. Another way to turn the screen on is by double-tapping it.
To turn the double-tapping feature on, follow these steps.
Step 1) Open the Settings app
Step 2) Tap on Advanced features
Step 3) Tap on Motion and gestures
Step 4) Toggle the “Double tap to turn on screen” switch on
3. Power saver mode
If the power saving mode of your Android phone or tablet is on, it will take over the brightness level of your phone and dim or switch off the screen as needed. The power saving mode ensures optimum usage of your phone’s battery and turns off certain features when not in use to keep your battery up and running for a longer time.
See how to stop screen dimming due to the power saving mode.

Child’s play, isn’t it?
4. Adaptive brightness
The adaptive or automatic brightness feature on Android adjusts the brightness levels automatically and dims the display depending on the environments. When in dark environments, it reduces the brightness and thus saves the battery.
But there’s a way to stop auto-dimming of your Android phone or tablet screen due to this feature.
How to stop screen dimming due to adaptive or auto-brightness?
To stop Android screen dimming due to adaptive brightness, turn adaptive brightness off.
Try these steps:

Some Android phones, like Samsung Galaxy phones, have a feature to dim or turn off the screen using the phone’s front camera. As long as the camera detects your face as you look at the screen, the screen will remain on.
Note: Only devices running Android 10 and above have this feature. The older versions have a Smart stay feature. Enable it from Settings > My device > Smart screen > Smart stay.
Here’s how to enable the feature:
Step 1) Go to Settings
Step 2) Tap Advanced features
Step 3) Tap Motions and gestures
Step 4) Turn on “Keep screen on while viewing”

The most common reason for Android screen dimming is auto-brightness. If the auto-brightness on your phone is on, it will adjust the phone brightness in response to the ambient light. To turn it off, open the notification tray on your phone and turn auto-brightness off.
