Why is my phone screen flickering?
El flickering It usually manifests as flashing, changes in brightness, tremors, or small ripples on the screen. Although it can cause concern, in most cases it is not due to an irreversible failure nor to physical harm.
Among the most common causes are: software bugs, problems with automatic brightness and, in specific cases, the malfunction of third-party applicationsHowever, hardware damage (drops, impacts, contact with liquids, or battery failure) cannot be ruled out, as this can also cause this annoying symptom. It is essential identify the source of the problem to apply the appropriate solution.
Therefore, the first thing to do is determine whether the error always occurs or only with certain apps, whether it occurs after an update, when the battery is low, or after a shock or exposure to moisture.
Most common causes of flickering on mobile screens
- Software errors and system settings: A faulty operating system update or a poorly optimized app can cause conflicts and flickering.
- Faulty or incompatible applications: Apps installed outside the official store, with bugs, or that are incompatible, can interfere with the panel's operation and cause flickering, especially if it only occurs when opening certain programs.
- Damaged or low battery: When the battery is damaged, swollen, or on the verge of depletion (below 5-10%), it can cause unstable power supply and, as a result, flickering or shaking on the screen.
- Automatic or adaptive brightness incorrectly calibrated: Light sensors may not respond correctly, resulting in brightness fluctuations and flickering, especially during rapid changes in ambient light.
- Charging problems or faulty accessories: A faulty charging cable or charger, or a poor connection, can cause the screen to flicker while the phone is plugged in.
- Physical damage and exposure to liquids: Bumps, drops, pressure on the screen, or contact with water can damage the panel or internal circuitry, causing flickering, lines, or even partial blackouts.
- LCD vs AMOLED Panel: Flickering is more common on LCD screens, especially on low- and mid-range phones, due to the backlighting technology, although it can also occur on AMOLED panels.
Detect whether the source is software or hardware This is the first step toward finding a solution. If the error only occurs in certain apps or disappears in Safe Mode, it's usually software-related. If the screen keeps flickering, even after restarting and restoring, the problem is likely physical.
How to distinguish whether it is a software or hardware problem?
- Safe Mode: Boot your device into safe mode. If the flashing disappears, the issue is related to a third-party app or setting.
- Quick hardware check: Observe if the flickering occurs after a fall, appears with lines, dead spots, or after the device gets wet.
- During charging: If it only appears when the phone is plugged in, suspect the cable, charger, or battery.
- Low battery: If this happens when the battery level is low, it may be due to battery wear.
Practical solutions for screen flickering
- Restart the mobile. A restart closes background processes and can resolve temporary software issues.
- Update the operating system. Go to Settings > Software Update and make sure you have the latest version, as manufacturers often fix known bugs that can affect the display.
- Turn off automatic or adaptive brightness. Go to Settings > Display > Brightness and select a fixed level. This will test if the light sensor is the cause.
- Check suspicious applications. If the flickering only occurs with a specific app, uninstall or update it. Also, check if you have any apps from unknown sources; it's best to uninstall them.
- Boot into safe mode. This way, you can rule out third-party app failures, as only the apps pre-installed by the system will run.
- Check the charging status and cables. If the error occurs when charging, try another official cable or charger.
- Reset the device to factory settings. If all else fails, back up and restore your phone to its original state by going to Settings > System > Reset options.
- Inspect the battery. If you notice that the back is swollen or the phone is getting abnormally hot, take it to a technical service for a replacement.
- Check the hardware. If the flickering persists after all of the above, there's likely physical damage. Only a technician can replace the screen or repair internal circuitry.

- Keep your phone clean and free of dust and moisture. Dirt buildup on the sensors can cause the automatic brightness to act erratically. Wipe with a dry cloth (without wetting the screen or connectors).
- Do not use covers that are too tight. If the case presses on the screen, flickering may occur.
- Avoid overheating the device. Playing for hours or using heavy apps can cause temporary image errors.
- Take a screen test. Many phones include a diagnostic test in Settings or with a secret code (such as *#0*# on some Androids) to check the panel.
- Caution when installing applications developed by third parties. Always install apps from Google Play or recognized brands to reduce the risk of conflicts and malware.
- Avoid unofficial cables and chargers. Low-quality accessories can damage the battery and screen in the long run.
- Please also update your apps. Not just the operating system: an outdated app can cause graphical glitches and flickering.
