Samsung Phone Flickering Screen After Dropping

When your phone screen flickers after a fall, you should identify the cause and apply proper solutions. A loose display flex cable connection or a broken IC chip may cause the screen to flicker. A defective GPU or minimal electrical damage to the motherboard are also sometimes the cause. Static discharge during the fall can harm screen parts while loose internal screws can create pressure on the display elements. 

The screen assembly and proximity sensor issues often show up as visible screen flickering. Professional examination and part replacement can resolve these problems. If you don’t have the skills, time, or tools to perform these steps at home, it is time to call for professional help or visit a trusted screen repair  to fix your Samsung phone’s screen flickering issues.

8 Solutions to Fix Samsung Phone Flickering Screen After Dropping

Try these solutions to fix Samsung phone’s screen display problems:

1. Check for Display Connector Damage

A fall can displace the display connector within a phone’s body, leading to screen flickering.

Fix:

• Power off the phone.
• Remove the back panel to locate the screen connector on the mainboard.
• Firmly reseat the connector and put it in its proper place. If unsure, bring your phone to a technician for professional evaluation and repair.

2. Inspect for AMOLED Screen Damage

The AMOLED displays on Samsung phones require careful handling since they break when exposed to force. A fall can cause:

• Microcracks (invisible to the naked eye)
• Random backlight flickering
• Green or purple stripes and flashing

Fix:

If you notice screen damage, the AMOLED needs replacement. Take your phone to an authorized Samsung repair facility or a trusted technician for professional screen replacement service.

3. Try Using the Phone with an External Display 

Connect your device to an external display if your phone supports USB-C to HDMI output. The screen hardware needs replacement when you observe no flickering through an external monitor. If flickering is present on the external monitor as well, it could indicate GPU or motherboard issues.

4. Look for Damage Around the Screen Frame

Drops can distort phone parts, causing tension between the casing and the display.

Fix:

• Check the borders and corners to verify if they are damaged or misaligned.
• When the device’s screen or housing parts are warped, they apply pressure to the display assembly, producing screen flicker, for which you need repair or replacement services.

5. Address Internal Hardware Damage

A hard drop can harm essential internal components responsible for graphics and performance, leading to issues like flickering, freezing, or sudden shutdowns. In smartphones, the GPU is not a separate, removable part — it is directly attached to the main chip on the motherboard.
Fix:
Since the GPU is fixed onto the motherboard, it cannot be replaced on its own. If it’s damaged, the entire motherboard must be replaced. This is a sensitive and costly repair that should never be attempted by the user. Always consult a professional technician for accurate diagnosis and safe repair.

6. Check the Display Cable

The flex cable links your phone screen to the main board. A hard drop can:

• Loosen it
• Partially disconnect it
• Damage the cable itself

Fix:

An expert can examine the display flex cable for looseness or damage and reseat it or install a new one as needed.

7. Replace the Entire Display Assembly

The extent of the display damage determines whether you need to replace the entire display assembly. Some common signs to look for are screen burns, poor touch sensitivity, and color distortion.

Fix:

Replacing the new OEM screen unit, including the touch screen and display, will restore all device functions.

8. Check the Light Detector

When your light sensor is broken, it disrupts brightness management and creates random flashes regardless of the adaptive brightness setting.

Fix:

Use the Samsung Members diagnostic tool to test the light sensor and replace the sensor module if it is faulty or unresponsive.

3 Reasons Why Your Samsung Screen is Flickering After Dropping

The main causes behind a flickering phone screen are: 

1. Loose or Damaged Display Connector: A drop can cause the screen connector to loosen, breaking contact with the motherboard. This damage can lead to flickering, ghosting, or random glitches.
2. Cracked AMOLED Display: Samsung AMOLED screens are more sensitive. Without surface cracks, internal layers could be damaged, causing flickers or colored lines.
3. GPU or Logic Board Damage: A hard drop can damage the graphics chip or the motherboard, leading to unstable display performance or constant flickering.

Conclusion

Identifying screen flickering problems after drops involves checking if key internal parts are displaced or broken. Check the display flex cable and the display IC chip. Next, you can examine the GPU functionality and test for faults in the motherboard. Check for broken electronics components and damaged internal shield plates.

Determine if you need an entire screen display replacement or inspect the performance of the light sensor. These solutions can help restore your phone’s screen to normal. However, if flickering on your Samsung phone screen continues, the issue is likely related to internal hardware damage.
