There are solutions. Vertical lines can be fixed by restarting the device, updating iOS, cleaning your screen, or setting the device back at factory settings.
This is the place to go if you’re currently struggling with it and want to get it fixed quickly.

You may have a hardware problem if the problem persists after trying all possible solutions. These are the solutions.
7. Clean your iPhone Screen
It’s absurd to say, but dirt and dust can cause serious damage to your screen. Screen protectors are often so relied upon that people neglect to clean their screens until they begin to see vertical lines.
You may notice lines on the screen from foreign agents such as water droplets or dust that get between the protector and the screen. This will continue until you properly clean them both.
Take off the screen protector. Wipe the iPhone screen gently with a fiber cloth until you remove any debris.
8. You can cycle charge the battery
The cycle charging of the battery involves charging the phone to 100% and then using it until it runs out to 0%. This could be used to reduce vertical lines after the phone has been charged to its maximum capacity.
9. Adjust the LCD Screen
The LCD cables could become disconnected from the logic board by sudden jolts, or even a fall. It doesn’t necessarily mean the iPhone screen has been damaged.
To check if the vertical lines disappear, gently push the iPhone’s touchscreen back in. To avoid further damage to the screen, use as little pressure as possible. These steps will help you do it:
- Two fingers should be placed on each side (the shorter ones) of the device. Press down with care, but firm.
- The vertical lines should disappear as soon as the pins connecting the LCD cables and the logic board screen are in place.
