recently, my friend gave me back the JK12(jiake).
at first, the touch screen is not responsive, after i did the reset, then the screen become "ghost touch"
I had read about it before with the Inew6000 in china forum, but i always thought that , it must be a software issue.
Until few days ago, i took back my friend's phone, after trying to do all the rom, tweak, still no luck, then i realised that it was a hardware issue.
tried to do something tought on the web, heat under the sun,dryer blow. but all with no success.
So, when i took out the screen's flex cable n examined carfully, i saw the contact point are so tiny and complicated, then i realised that , it might be the contact point is not sitting in the right position, they might have a short circuit that cause the ghost touch.
So i pulled out the flex cable bit by bit, and tried to on it, finally, i get the flex cable sitting in the right position.
Now , the phone is back in normal condition.
Hope this will help people who have ghost touch
