The red line on an Android phone screen is usually due to hardware. If you dropped your device, the display ribbon connector may be loose. In this case, the red line appears because the LCD circuit loses contact with the flexible cable. Since screen replacement isn’t necessarily an easy Android phone fix, it doesn’t hurt to try a few other things before calling it quits. You can test if this is actually a hardware problem by booting the phone into safe mode. If this causes the line to disappear, a simple factory reset or software update could solve your problem.
How do I fix red lines on my phone?

Interestingly, those whose Android phone screens displayed the red line sometimes saw the problem disappear on its own. Others solved the hardware problem by putting the phone in their hands. This last tip probably helped the lost contact reconnect, but before you switch to medieval mode on your Android, do some software troubleshooting first.
A soft reset is a good first step. Press the Volume Down and Power buttons together for about 20 seconds. This won’t erase any of your data, but it will clear RAM and cache, which is exactly what you need. If the red line is still there, booting the phone into safe mode should be your next step: hold down the power and volume up buttons until the safe mode prompt appears. This is a great way to diagnose if third-party apps are contributing to your problem.
If the line wasn’t there during your safe mode excursion, check your phone for software updates. If that doesn’t work, as a last resort, do a full factory reset (you can find this option in the system settings). Make sure to back up your data, because the phone will suddenly go completely vanilla. In the worst case, the red line will still be there. Unfortunately, this probably means your phone has developed a mysterious hardware problem or has a loose connector. The only solution is to get a new screen.
Will the warranty cover repairs?

Don’t panic if a green or red line appears on your Android phone screen. This is a known issue with some phones, like Samsung phones, which, believe it or not, offer free screen replacements if you meet the eligibility criteria. Applicable to S20, S23, and Note 20 models, if the problem occurred within three years from the date of purchase or activation and shows no visible signs of physical damage, Samsung can remedy the problem free of charge.
Google has also rolled out an extensive repair program for Pixel 8 phones that have succumbed to the “vertical line curse.” Similar to Samsung, if this issue manifests within three years of purchase, the tech giant will offer additional coverage. Keep in mind that not all manufacturers are this generous, so you may have to bear the brunt of the cost even if you face a hardware defect.
Other than that, you don’t have many options on your hands. Check your warranty and if that fails, some manufacturers offer resources for self-repair, while others partner with websites where you can purchase DIY kits or genuine replacement parts.
