8x8 screen point touch drift solution peng 17:24:11 reply to my 818 has also appeared float, or even appeared screen do not touch. Here we will share the summarized causes and solutions:
There are three main reasons
1: software problems. Solution: hard boot. If the ROM cannot be flushed.
2: screen cabling problems. Solution: disassemble the machine and pad the adhesive tape on the screen.
3: The screen touch screen is in contact with the machine's front shell edge, resulting in multi-point sensing. The solution is to remove one of the following dust circles in the front shell, or string down 2 ~ 3mm. (In the Red Circle in Figure 15)

The software accounts for a very small number of problems with the machine of friends in the jar, and a small part of the problem is the wiring problem, and most of them are actually the contact problems between the touch screen and the front shell. It will take some time for a pen to be written after the host is split because the contact between the screen and the front shell is not so compact. After a period of time, the press is very tight, and the problem occurs again, another possibility is that, after a tape is inserted in the cable, the motherboard and the screen will be put under a little pressure after the pen is inserted. The screen cable is the right bottom of the front of the screen. The lever principle is as follows, there is a lot of pressure here, and there will be less pressure on the lower left side of the screen. So immediately recurs after the pen is pulled out! After a while, it failed because of a long time. The tension between the screen and the motherboard gradually offset the pen pressure, and the design defect pressure in the lower left corner came back!
You can take a closer look at the large gap in the upper part of the screen of 818, with few or even no gaps in the lower part, especially in the lower left corner. This is a design issue. Most screen offset friends are in the lower left corner, right? Which of the remaining friends is in the lower right corner? The top half of the screen has a problem. It must be another reason!
