4. Cleaning the iPhone Screen

The accumulation of dirt and debris can lead to significant deterioration of the screen of an iPhone device. It is not uncommon for individuals to overly rely on screen protectors, thereby failing to perform adequate maintenance on their device until noticeable scratches begin to appear on the screen. The presence of water droplets and dust particles between the screen and the screen protector can result in the formation of scratches on the surface of the iPhone screen. To address this issue, it is recommended to remove the screen protector and gently clean the screen using a soft cloth until all visible streaks and debris are removed.

5. Cycle Charge the Battery

A battery charging cycle refers to the process of charging the device to 100% and then using it until it is completely drained to 0%. This can eliminate any straight lines after the phone is fully charged again.

6. Adjusting the LCD Screen

Vertical lines can also be caused by the LCD cable disconnecting from the logic board due to jolts or sudden drops. In this case, you can gently push the iPhone screen inwards to reconnect the cable wires to the logic board to see if the scratches disappear. Use the lightest force possible to avoid breaking the screen. You can perform this with the following steps:

  • Step 1: Apply gentle pressure to both sides of the device (the shorter sides) with your two fingers.
  • Step 2: After the logic board and LCD cable connection feet are properly positioned, the vertical lines will immediately disappear.
