Practical Example 1: A User Is Looking To Fix Horizontal and Vertical Lines On Android Phone

Why are there horizontal & vertical lines on my phone screen?

Hi everyone,

I have a Huawei Ascend G7(bought in 2015) and didn’t have any screen issues up until a few days ago.

  1. At first I noticed a faint yellow patch in the center of the screen, only visible when the screens dark or tilted at an angle.
  2. Yesterday, thin horizontal blue/black lines appeared on the entire screen but with spaces at regular intervals so that I can still see my screen’s contents and use it.
  3. I restarted the phone and it went away, only to return after 5 minutes. Restarting, in both safe mode and normal, doesn’t do anything now.
  4. I also noticed vertical yellow/green streaks when the screen content’s of darker colors.

The screen is still responsive like it normally is and I can see things on it.

Note: I sometimes use a bit of tissue dabbed in dettol to clean the screen, then wipe it off with paper soaked in a bit of water and then dry it with another tissue. Do you think this could have done something? Also, this started happening out of nowhere, I did not install any new apps.

(I’ll add a photo later on in the day when I have access to a laptop)

Much thanks in advance!

If it gets fixed then it means that the cover that you are using on your phone is giving pressure on your device and due to this you encounter the problem.

If your phone has been exposed to water and it starts to show lines on the phone’s screen, then there could be two possibilities:

In the case of a short circuit, there could be several situations. Anyway, we actually don’t know, if the phone is really short-circuited or not, correct?

Hence, it is suggested that you must first dry your phone:

  • Remove the SIM card, memory card and battery.
  • Now, put the phone in the jar filled with rice.
  • Leave the phone in the rice for 2-3 days.
