Part 3. 11 Ways to Vertical Lines on iPhone Screen

Way 1. Force Restart iPhone

A force restart is similar to taking out the battery and putting it back on. It is going to completely shut down all the apps and programs running on your iPhone. Whenever you see there are lines across the screen, you can fix it easily by hard rebooting your iPhone. After the hard reboot, the lines on the screen may disappear. To hard restart your iPhone, follow the tutorial enclosed below.

iPhone 6 or former iPhones: Press the "Power" and "Home" button on your iPhone simultaneously for around 13 seconds. You will feel the vibration of the phone, then it will turn on.

iPhone 7 and 7 Plus: Press the "Sleep/Wake" and "Volume Down" buttons at the same time until you see the iPhone turn back on.

iPhone 8 and later iPhones: Press the "Volume Up" button and release it quickly, then press the "Volume Down" button and release it quickly; next hold the "Power" button until you see the Apple logo on the screen.

Note: You can also close your iPhone first and wait for one hour. Then open it to see if the vertical lines disappear from screen. This method is to restart the device. The difference is that it requires you to wait for a period of time to restart. A user from Apple community gave this workaround. He speculated that the problem may have been caused by the phone overheating, so just wait a while for the device to cool down.

Way 2. Clean Phone Screen

It might seem ridiculous, but in some cases, iPhone screen lines vertical problem are caused by things as little as water drops or dust. These things can be difficult to notice when you have a screen protector on the screen. If the water drops or dust get stuck between the screen and the screen protector, it is natural that there will be vertical lines across the screen. Therefore, you might as well remove the screen protector, clean the screen with a cloth and see if the lines have gone.

Way 3. Cycle Charge the Battery

Essentially, cycle charging means charging the battery to 100%, then using it until it drains to 0%. When the phone is charged to capacity again, the vertical lines might disappear.

Way 4. Readjust the LCD Screen

It is also possible for vertical lines to appear when LCD cables become disconnected from the logic board during sudden jolts or a fall. A slightly shifted iPhone screen does not necessarily mean that it is damaged; it is just a slight shift.

It might be workable to remove the vertical lines by gently pushing the iPhone's screen back into place to reconnect the cables with the logic board. Make sure that you do not apply too much pressure to the screen in order to prevent the screen from breaking further. The steps are as follows:

• Step 1. Put two fingers on either short side of the device and press down firmly but carefully.
• Step 2. The vertical lines should disappear as soon as the pins connecting the logic board screen and LCD cables are connected.

Way 5. Update iOS Software

• Step 2. If there is an available update, tap on the "Download and Install" button to confirm your update. The updating process will begin, what you need to do is just make sure the Wi-Fi connection is good and wait for the update to finish.
