Pixel 9 Pro Display Issues: Investigating Screen Flickering and Green Line Problems, Potential Causes and Solutions

Reports have surfaced regarding display issues affecting the Google Pixel 9 Pro and Pixel 9 Pro XL smartphones. Users have reported problems such as screen flickering and the appearance of vertical green lines. Google has acknowledged these issues and has launched an extended repair program to address them.

Common Display Problems

• Screen Flickering: Users have reported their Pixel 9 Pro displays rapidly changing in brightness, as though a switch is being flipped on and off. This can occur in various apps or system-wide.
• Vertical Green Lines: A persistent vertical green line running from the bottom to the top of the screen has been observed on some devices.
• Other Reported Issues: Some users have also noted dull or washed-out colors, inconsistent auto-brightness, and dim wallpapers. In some instances, the screen may have a green or yellow tint, particularly on dark backgrounds.

Potential Causes

Several factors could be contributing to these display issues:

• Software Glitches: Software bugs introduced through updates can sometimes cause display malfunctions. Faulty software can affect color calibration, brightness levels, and overall display performance.
• Hardware Defects: The green line issue, in particular, may indicate a hardware problem with the display panel or its connections. It could be related to a loose flex cable or a problem with the display's DDIC flash memory.
• Physical Damage: Although not always visible, internal damage from drops, pressure, or water exposure can cause display problems. A swollen battery can also put pressure on the display, leading to malfunctions.
• Incorrect Settings: In some cases, incorrect display settings or power-saving configurations can affect screen visibility. Adaptive brightness settings, if not properly calibrated, can also lead to inconsistent brightness levels.

Troubleshooting and Solutions

If you are experiencing display issues with your Pixel 9 Pro, here are some troubleshooting steps you can try:

1. Restart Your Phone: Restarting can often resolve temporary software glitches.
2. Check Display Settings: Verify that your brightness and color settings are appropriately configured. Disable adaptive brightness to see if it resolves flickering issues.
3. Update Software: Ensure that your phone's operating system and apps are up to date. Updates often include fixes for known bugs.
4. Safe Mode: Boot your phone in safe mode to determine if a third-party app is causing the problem. If the screen works in safe mode, uninstall recently downloaded apps one by one to identify the culprit.
5. Factory Reset: As a last resort, perform a factory reset. This will erase all data on your phone, so be sure to back up important files first.
6. Hardware Check: Examine the phone for any visible signs of physical damage, such as cracks or water damage.
7. Extended Repair Program: Google has launched an extended repair program for the Pixel 9 Pro and Pixel 9 Pro XL, covering vertical lines and screen flickering for three years from the original purchase date. Check Google's support page to see if your device is eligible.
