Main Reason
The most common reason why phone screen flickers is unstable display power caused by brightness changes and software control.
Modern phones adjust screen brightness automatically. When the light around you changes, the phone automatically adjusts its brightness to keep the display visible. This quick adjustment can make the screen look like it is flashing or flickering.
Low brightness levels also matter. When the screen is very dim, phones use a method that rapidly turns pixels on and off to save power. Your eyes may notice this as flickering, especially in dark rooms.
Software updates can also affect display control. After an update, the phone may struggle to balance brightness, colour, and refresh rate properly. This can cause temporary flicker until the system settles or settings are adjusted.
High screen refresh settings can add to the issue. If the phone keeps switching between refresh rates to save battery, the screen may briefly flicker during the change.
In simple terms, when your phone struggles to keep the screen light steady, flickering becomes visible.
Other Common Reasons
- Auto-brightness issues – The screen keeps adjusting to light changes too often.
- Low battery or power saving mode – The phone limits display power, causing instability.
- App conflicts – Some apps don’t work well with display settings and cause flicker.
- Screen damage – Small internal damage can affect display signals.
- Overheating – Heat can disturb how the screen receives power.
What You Can Do / How to Fix / Prevention Tips
- Turn off auto-brightness and set brightness manually.
- Increase brightness slightly, especially in dark rooms.
- Restart your phone to refresh system control.
- Update apps and the phone system if updates are available.
- Disable battery saver and test if flickering stops.
- Avoid using the phone while charging if the screen flickers.
- Keep the phone cool and avoid long use in hot environments.
Is This Normal or a Problem?
Small flickers during brightness changes are common and usually normal. They often appear in low light or right after updates.
If the screen flickers constantly, shows lines, or happens even on high brightness, it may be a display issue. In that case, basic checks are safe, but ongoing flicker should not be ignored.

Does battery saver cause screen flicker?
Sometimes. Battery saver limits power and can affect display stability.
Is screen flickering harmful?
Usually no, but constant flickering may cause eye discomfort.
Will restarting fix screen flicker?
In many cases, a restart helps reset display control.
Conclusion
Screen flickering is often caused by brightness and power control issues. Most cases are minor and easy to fix. Simple setting changes usually help. If flickering continues, it’s a sign the screen needs attention.
