Disable Auto-Brightness

The first and most common reason for fluctuating screen brightness is the Auto-Brightness feature. This feature adjusts the screen brightness based on the surrounding light levels.

To disable Auto-Brightness on your device:

2. Select Accessibility
3. Tap Display & Text Size
4. Toggle off Auto-Brightness

For Android:

1. Go to Settings
2. Select Display
3. Tap on Adaptive Brightness or Auto-Brightness (depending on the device)
4. Toggle off the feature

Turn Off True Tone

For iOS devices, the True Tone feature can also affect screen brightness. True Tone adjusts the color temperature of your device’s display to match the ambient light, which can cause brightness changes.

To turn off True Tone on your iOS device:

1. Go to Settings
2. Select Display & Brightness
3. Toggle off True Tone

Disable Night Shift Mode

Night Shift Mode reduces blue light emitted by your device’s screen, which can cause the screen to appear dimmer. Disabling this mode may help with brightness issues.

For iOS:

1. Go to Settings
2. Select Display & Brightness
3. Tap on Night Shift
4. Toggle off the Scheduled option

For Android:

1. Go to Settings
2. Select Display

For iOS:

1. Go to Settings
2. Select Display & Brightness

4. Select a longer duration for the screen timeout

For Android:

1. Go to Settings
2. Select Display
3. Tap on Screen Timeout or Sleep (depending on the device)

Overheating can cause your device to lower the screen brightness to protect itself. If your device is hot to the touch, let it cool down before using it again.

1. Power off your device
2. Remove the case, if applicable
3. Allow it to cool down in a well-ventilated area
