Screen flickering is one common problem with a display that is experienced when the screen of the device rapidly flashes, blinks, or changes in brightness. The problem may show itself on smartphones, laptops and desktop monitors as they make it difficult to comfortably utilize the device. In many cases, if there is a flickering on the screen, it can be due to minor issues with either the software that is being used on the computer as well as improper display settings, but in some cases, it may be due to damaged hardware.
Although, the issue may sound like a serious one there are a number of simple troubleshooting steps which can often resolve the issue. Understanding the reason for what is screen flickering can help users quickly identify what the issue is and restore the display ability of their device.
Understanding Screen Flickering
Screen flickering occurs when the screen is not steady in its brightness or image. Instead, the screen may flash repetitively, dim or have unstable lighting patterns.
This problem could be occasional or continuous depending on the cause of the problem. Some users flicker when they watch videos or scroll whereas others flicker randomly throughout the day. Besides the fact that it is distracting, continuous flickering may also lead to eye strain and discomfort.
Both software and hardware problems can become the reason for this problem to exist so knowing the source of where the problem is coming from is vital before a fix is implemented.
Common Causes of Flickering on the Screen
There are a number of reasons why a device screen may flicker. One of the most common factors is the auto-brightness or adaptive brightness feature. This feature automatically adjusts the brightness level of the screen according to the lighting conditions in the surroundings. If the light sensor is not working, the brightness will continue to change and it will flicker.
Another possibility could be night mode or blue light filter settings. These features control the display color temperature to minimize eyestrain, and at times, to interfere with the balance of the brightness of the screen.
Outdated software or system bugs could also be the reason that the screen is not stable. If the Operating system is not updated or has errors, this leads to abnormal functioning of the display.
Additionally, third-party applications could lead to fights with the system’s Display processes. Applications that control screen overlays, themes or brightness sometimes cause flickering.
In some cases, the problem may be caused by hardware problems such as a faulty display panel or disconnected internal connections.
Signs of Screen Flickering
Screen flickering could manifest and show itself in a number of ways depending on the device and the reason for its occurrence. Some users are able to notice the display’s fast blinking, while others will see the changes in brightness suddenly.
Common signs include:
- Repeated flashing or blinking of the screen
- Random brightness changes
- Lines or visual glitches appearing on the display
- Temporary blackouts followed by normal display
If these symptoms are occurring frequently then there should be a troubleshooting that is done to find the cause.
Simple Fixes for Screen Flickering
In many instances flickering of the screen can be fixed with some simple adjustments.
Restart the Device
It is often useful to power off the device and power it back on in an effort to correct a temporary glitch. A reboot interrupts with background processes which can be causing display instability.
Disable Auto-Brightness
Turning off the adaptive brightness may help to stabilize the screen if the light sensor is causing rapid light sensor brightness adjustments.
Turn Off Night Mode
Night light, or blue light filter settings, once in a while may result in flickering. Being able to shut them off for a temporary period of time can help to establish whether they are responsible or not.
Update the Software
Installing the latest system updates can fix bugs that are associated with the display. Constantly updated software usually has adjustments and patches for stability.
Use Safe Mode (Android)
Booting into Safe Mode will give the phone the ability to work without the 3rd party apps If the flickering intensity stops in Safe Mode, it could be because of a recently installed app.
When Hardware Can Be a Potential Problem
If the screen is still in a flicker state even after all fixes in the software, then the problem can be associated with hardware damage. A broken screen or broken connectors on the inside or graphics processing can cause the flickering to always be there.
Physical damage in the form of drops, moisture or overheating may also be a factor in the working of the screen. In this case visiting a professional repair center is usually the best.
Conclusion
Screen flickering is a very frustrating and common problem that can happen to smartphones, laptops, and monitors. In many cases, it is software glitches, brightness settings or problematic apps. Simple fixes such as restarting the device, disabling adaptive brightness or updating the system usually help with these without any delay.
However, if the flickering is something that has persisted on and on even after troubleshooting, then this could mean that there’s hardware damage that needs to be repaired by a professional. Identifying the cause at an early phase can help in avoiding more display problems as well as ensuring a smooth device experience.
