Samsung s2 1 has stripes on both sides of the screen, one

What's with the stripes on the mobile phone screen?

Cable problem: the cable of the mobile phone is used to connect the mobile phone motherboard and other modules. When the screen of the mobile phone is unfolded, there are color stripes, which is probably a problem with the cable of the screen. In the past, the damage of flat cable generally occurred in sliding and flipping machines, and this situation was rarely encountered in straight smart phones. However, if you have ever dropped your mobile phone, or continue to use it under severe fever, it is likely to cause the cable to loosen or even burn out, resulting in abnormal screen display.

Motherboard problem: It is less likely, but Apple iPhone6 users have reported the problem of gray edges and touch failure at the top of the screen, because the chips on the motherboard are easier to be soldered. Software problem: Unlikely, it usually happens after firmware upgrade or wallpaper replacement, and the abnormal screen display has nothing to do with hardware.

If it is determined that it is a software problem, Android can brush the machine, and if the wallpaper has influence, it can be replaced and restarted. However, with the continuous progress of mobile phone technology, there are fewer and fewer colored bars on the screen of mobile phones. If your mobile phone has been in service for a long time, it should be the simplest and rudest way to change it directly.
