[How-To] Ghost touch - fixing ghost touch

[stevenma61]

up to this morning, the ghost touch did not come back.

edit:
the flex cable i reposition/adjuted is the lcd flex cable, not the digitiser flex cable..

Hey man, thanks for good info! But is still does not make sense, how adjusting LCD flex cable helped you solve ghost touching? I had this issue on a few phones (they were branded, not china phones). Ghost touch can disappear sometimes and then re-appear. Make sure that it is not this situation, because in my experience NOTHING CAN FIX THAT!!! I always ended up changing digitizer or the whole screen (in case or samsung galaxy R, where it is not possible to change digitizer separately).
So just test it at least one week and see if it actually fixed it! Because it still does not make sense to me....

yes. it look strange, but as we know, electronic are sensitive,

because the flex cable does not sit in the proper position , when the contact over lap the contact, it behaves strange.

for my case. once i put the screen flex cable all the way to the end, once i start the phone, in just 30 second. then the screen jump from one page to another , sometime menu pop up,

then i repostion the flex cable, then i on the phone, then there is no more jumping.
so i am quite sure because of the short cicuit craeted by screen flex cable, then the touch jump.

if u look at screnn flex cable, it is much complicated than the digitizer flex cable, the digitizer is straight all the way, but not the screen cable, . for screen cable and the cable connect the main board to the bottom(mic, and media speaker), the cable is complicated also. u cannot put the cable all the way, if the cable was not cut in properly.

that is why , for workers who install all this to complete a phone, they just try to put the cable all the way in the socket , in most of the cases, it works, but for some cases, if the cable was not cut/manufactured and the socket a little bit out of postion. then it create a short circuit after the phone is on, once the contact get heat, it expand.

if u r lucky, u might use it for few weeks, if u r not lucky, then u can use it for few hours.

so try to look at the flex cable carefully, and u think it might not siiting in the right position, then adjust it.

Anyway, it is good to try, at least i tried mine, and it is workng.


Edit
to troubleshoot a problem when the problem only comes in a while, it is hard
but for my case, it is easier, because , once i on the phone, the ghost touch appear, so once i repostion the cable, then there is no more ghost touch.
