Understanding Samsung S25 Ultra Screen Lines

The Samsung S25 Ultra is known for its exceptional AMOLED display—vibrant, detailed, and sharp. However, even the most advanced screens can develop vertical or horizontal lines that ruin your viewing experience.

These screen lines often appear as thin green, purple, or black streaks that cut across the display. In some cases, they flicker or worsen over time. Understanding the root cause is key to fixing the issue effectively and preventing future damage.

Common Types of Screen Lines on Samsung S25 Ultra

  1. Vertical lines – usually caused by hardware damage or loose display connectors.
  2. Horizontal lines – often linked to internal short circuits or software glitches.
  3. Flickering or color-shifting lines – indicate GPU or display driver issues.
  4. Dead pixel bands – show permanent damage to the AMOLED layer.

Why Screen Lines Appear After a Drop or Update

It’s common to notice screen lines after dropping your phone or following a firmware update. Physical impact can loosen the display cable, while software updates might temporarily disrupt display calibration.

In rare cases, moisture exposure or overheating can trigger screen flickering or line artifacts, especially if the internal seal is compromised.


Quick Fixes You Can Try at Home

Before heading to a repair shop, try these simple troubleshooting steps to rule out software issues.

Restart and Safe Mode Boot

Restart your Samsung S25 Ultra. Sometimes, background apps or system glitches can cause temporary display errors.

If the problem persists, boot into Safe Mode to see if the lines disappear. If they do, it means a third-party app is responsible. You can then uninstall recently installed apps to fix the issue.

Software Updates and Cache Clearing

Outdated firmware can cause display driver conflicts.
Go to Settings → Software Update → Download and Install.

Next, clear the system cache:

  1. Power off your phone.
  2. Hold Power + Volume Up until recovery mode appears.
  3. Select Wipe Cache Partition.
  4. Reboot your phone.

This process clears corrupted temporary files without deleting your data.

Factory Reset (Last Resort Option)

If all else fails, perform a factory reset:
Settings → General Management → Reset → Factory Data Reset.

⚠️ Backup your data before proceeding. This step removes all files and resets your device to default conditions—sometimes eliminating deep software glitches that cause display anomalies.


When It’s a Hardware Issue

If screen lines remain after software fixes, it’s likely a hardware problem. Let’s explore what could be wrong internally.

Display Connector Damage

When a phone is dropped, the display flex cable may become partially detached. This causes flickering or intermittent lines. Reconnecting it properly usually fixes the problem, but doing so requires opening the device—a job for professionals.

Water or Moisture Exposure

Even minimal water exposure can short-circuit the display circuitry. Over time, corrosion can lead to green or purple lines appearing. If your phone has been exposed to water, power it off immediately and seek professional help.

Defective AMOLED Screen

If you see persistent or expanding lines, the AMOLED display itself might be damaged. Replacement is the only permanent fix in such cases. Using genuine Samsung parts ensures full brightness and color accuracy after repair.
