Hi!
I have broken the display on my Z2.
I have ordered a new one online and changed it. Soon I realized it's not working properly (ghost touches and unresponsive screen). After looking for a solution, I found out that this may be a grounding problem.
Since i saw, that the new display didn't come with adhesive covers for the chips on the flex cable, i have fitted them from the original display, but the problem still persists.
So how do I properly ground the display?
Does the bottom metal part of the display flex cable, have to touch the metal part of the frame? I suspect that sometimes it doesnt (new display didn't have the grey adhesive, the original had - but I can't remove it). Do I have to fix it with some kind of conducting adhesive?.
What about the top metal part of the display flex cable? Must it touch (ground) somwhere or it's not neccessary?.
Do I have to be carefull that some parts of the flex cable doesnt touch some other part of the phone?
BTW, I know the display isn't faulty because if I remove the back cover, sometimes i get perfect screen rensponse (maybe i ground it with my hand).
Thanks in advance.
