Is your Samsung phone screen flashing on and off? This common issue can be frustrating and might indicate a deeper problem. If your Samsung phone screen flashes intermittently, you can fix it using dedicated methods.
You can try a factory reset or safe mode, clean the cache, switch the screen refresh rate, utilize a new charger, check for damage, turn off developer options, update your phone, and turn off adaptive brightness. These solutions usually resolve the problem without requiring a professional repair.
Ways to Fix a Flickering or Flashing Samsung Phone Screen
Here are some proven solutions to resolve Samsung phone screen flickering issues:
1. Disable Auto Brightness
Adaptive brightness changes your screen’s light level automatically. Sometimes, it causes the screen to flicker. To turn it off:
- Go to “Settings.”
- Tap on “Display.”
- Turn off “Adaptive brightness.”
This can stop the screen from flashing when the light around you changes.
2. Modify Display Refresh Rate Settings
Some Samsung devices have high refresh rates (90Hz or 120Hz), which may cause flickering with certain apps. Lowering the refresh rate might resolve flickering. To lower the refresh rate:
- Go to Settings.
- Tap on Display.
- Select Motion smoothness.
- Choose Standard (60Hz).
Reducing the refresh rate stabilizes the screen and eliminates flashing.
3: Update System Software
Samsung regularly releases patches that address display-related issues:
- Connect to a stable Wi-Fi network
- Launch “Settings.“
- Scroll to Software update
- Select “Download and install.“
- If an update is available, follow the on-screen instructions.
- After updating, restart your phone.
4. Change the Charger or Cable
A damaged or incompatible charging cable may cause screen problems. Try using a different Samsung-approved charger or cable to determine whether the flickering is related to power supply inconsistencies.
Tip: Always use cables and chargers that Samsung has approved.
5. Inspect for Physical Damage
Have you spilled water on your phone or dropped it? The screen may flicker as a result of physical or water damage. You should look for:
- Cracks or dents.
- Signs of water inside the screen.
- The screen turns green or black randomly
6: Reset Display Settings Only
Before doing a factory reset, try resetting just the display settings:
- Go to “Settings.“
- Tap “Display.“
- Look for the Reset display settings or similar option (location varies by model)
- Confirm when prompted
- Restart your device
7. Try Safe Mode
Your screen may flicker when using certain programs. Only the standard system apps are used in safe mode. To enable Safe Mode:
- Press and hold the “Power” button.
- Tap and hold “Power Off” until “Safe Mode” shows up.
- Tap “Safe Mode” to enter it.
If your screen works properly in Safe Mode, a third-party app is likely causing the issue. Uninstall any recently added apps to identify the culprit.
8. Clear System Cache
Corrupted temporary files can affect display performance:
- Power off your Samsung device completely.
- Press and hold Volume Up + Power (or Volume Up + Bixby + Power on some models).
- Release when you see the Android logo.
- In recovery mode, use volume buttons to navigate to Wipe cache partition. Then, press the Power button to select.
- Select Yes to confirm and wait for the process to complete.
- After completing, choose Reboot system now.
9. Perform a Factory Reset
A factory reset may resolve your phone screen flashing problem if none of the above methods work. However, it will remove everything, so backup your essential data before doing this.
- Go to “Settings.”
- Tap “General Management.”
- Select “Reset.”
- Choose “Factory data reset.”
Use this solution only after every other method has failed.
10: Contact Samsung Support or a Trusted Repair Technician
If none of the previous steps work, it’s time to seek professional help by contacting Samsung Support or visiting a trusted third-party authorized service shop. Open the Samsung Members app on your device and go to “Get Help” or “Support” to access options like live chat, online support, or finding a nearby service center.
Alternatively, you can take your device to a reputable third-party repair shop that is authorized and provides professional Samsung phone repair services. Be sure to document when the screen flickering occurs—such as during specific apps or actions—to help technicians diagnose the issue more effectively. Also, back up any important data before handing over your device, as some repairs or diagnostics may affect stored information.
Causes of Screen Flickering on Android
You can prevent the problem in the future by knowing why the screen on your Samsung phone is flickering. These are a few of the most typical reasons.
- Water Damage:Even a tiny bit of moisture from the headphone socket or charging port could harm your phone’s internal components. If not adequately dried or fixed, the screen may flicker, show lines, or turn black. In such cases, it’s important to know how to properly remove water from inside phone screen to prevent long-term damage.
- Physical Damage: Dropping your phone on a hard surface might cause internal screen components to crack or become loose. Even if the external glass seems fine, the internal display may be damaged, causing the screen to flash or behave unresponsively. This type of impact is a common cause of LCD screen damage.
- Power Source or Charging Cable Issues: If you use a damaged or inexpensive charging cable or adapter, your phone may receive irregular power. As a result of this power surge or drop, your phone’s screen may flicker or flash abruptly, especially when charging.
Conclusion
The screen of your Samsung phone flashing on and off is typically a fixable problem. Turning off developer options, adjusting the screen refresh rate, switching to a different charger, checking for physical or water damage, updating your phone, going into safe mode, deleting the cache, or doing a factory reset are just a few easy fixes you may attempt.
