Screen flickering can make your phone hard to use. The display might flash, dim, or show random brightness changes that can strain your eyes and ruin your experience. If this is happening on your Tecno Pova Slim 5G, it’s often caused by software glitches, outdated firmware, or adaptive brightness misbehavior.
Below are the most common causes and reliable solutions you can try.
Why Your Tecno Pova Slim 5G Screen Might Be Flickering
- Adaptive brightness or Eye Care mode acting up.
- Outdated system software or display driver.
- Screen refresh rate conflict with certain apps.
- Third-party apps causing visual instability.
- Overheating or low battery triggering power-saving dimming.
Turn Off Adaptive Brightness.
Adaptive brightness automatically adjusts screen brightness based on lighting conditions. However, it can sometimes overreact and cause flickering when light changes too quickly.
- Open Settings, and then tap Display & Brightness.
- Tap Adaptive brightness, and then toggle the switch off.
Once disabled, manually adjust the brightness slider to a comfortable level and observe if the flickering stops.
Adjust Screen Refresh Rate.
A high refresh rate makes animations smoother, but some apps or low-power states may conflict with it. Changing it can help stabilize your display.
- Open Settings, and then tap Display & Brightness.
- Tap Screen refresh rate, and then choose Standard or Auto-switch instead of High.
This change can reduce unnecessary strain on the GPU and keep the screen stable.
Update System Software.
Outdated firmware can cause compatibility problems with display drivers. Keeping your Tecno Pova Slim 5G up to date ensures optimal performance.
- Open Settings, and then tap System.
- Tap Software update, and then tap Check for updates.
If an update is available, follow the on-screen instructions to install it. After updating, restart your device and test the display again.
Restart in Safe Mode.
Third-party apps are often the hidden cause of screen flickering. Safe Mode temporarily disables all downloaded apps to help you identify the culprit.
- Press and hold the Power key until the power menu appears.
- Tap and hold the Power off option, and then select Safe mode when it appears.
If the flickering stops in Safe Mode, uninstall recently installed or suspicious apps one by one after restarting normally.
Turn Off Hardware Overlays.
Hardware overlays help your phone manage graphics more efficiently, but they can sometimes cause visual issues. Disabling them lets the GPU handle all screen rendering directly.
- Open Settings, and then tap System.
- Tap Developer options, and then toggle off Disable HW overlays.
If Developer options are not visible, go to Settings > About phone, tap Build number several times until it says “You are now a developer.” Then retry the above steps.
Check for Overheating or Low Battery.
When your phone overheats or battery is critically low, the system may dim or flicker the display to protect hardware.
Avoid using the phone while charging or under direct sunlight. Let it cool down and keep the battery level above 20 percent whenever possible.
Screen flickering can be annoying, but it’s usually fixable with these simple steps. By adjusting display settings, checking for updates, and managing apps, your Tecno Pova Slim 5G should return to smooth and steady performance.
FAQs
Why does my Tecno Pova Slim 5G screen flicker only when the brightness is low?
This often happens when adaptive brightness tries to adjust the screen in dark environments. Turning it off usually fixes the issue.
Can a screen protector cause flickering?
In rare cases, a poor-quality screen protector can affect touch and light sensors, causing brightness fluctuations. Try removing it temporarily to check.
Should I factory reset my phone if flickering continues?
Factory reset should be your last option. If the problem persists after all fixes, back up your data and perform a reset to rule out software corruption.
