How to Fix Low Screen Brightness at Full Setting on TECNO

If your TECNO phone's screen remains dim even when brightness is set to maximum, it's a hardware concern that needs immediate attention. Low brightness affects visibility and can indicate display degradation or battery issues. This guide provides practical solutions to restore optimal brightness levels.

Steps to Fix Low Screen Brightness on TECNO

Disable auto-brightness: go to Settings > Display & Brightness and toggle off the adaptive brightness option.
Set brightness to maximum manually: swipe down from the top to open quick settings, drag the brightness slider to 100%, and hold for 3 seconds to lock.
Check for power-saving mode: go to Settings > Battery or Power Management and temporarily disable any battery-saving features.
Clean the display and sensors: power off your device and gently clean the screen and ambient light sensor with a soft, lint-free cloth, then restart.
Update system software: go to Settings > About Phone > System Updates and install any available updates.
Factory reset as last resort: backup your data first, then go to Settings > System > Reset Options > Erase All Data.

🤔Note:

If brightness remains low after trying all software solutions, the display backlight or LCD panel may have a hardware defect. In this case, contact TECNO support or visit a certified repair center for professional evaluation.
