So i have recently received my nexus 7 tablet and right from the start i notice the touchscreen was having problems registering input and sometimes giving “ghost” input making the tablet do random things.
Here is a video showing the so called “ghost” input:
And the not registering of input:
As you can see, these issues make the nexus 7 quite unusable. Since i dont like sending my unit back to Asus and wait 3-4 weeks for RMA i decided to open up the device and see what the problem was.
Opening the nexus is quite easy, just use your finger nail or something else to pry open te back. Once open you should see something like this on the right side:
There is a black piece of foam tape on the cable attached to the touchscreen. when touching this tape or slightly pusshing down on this part of the device touch input starts to go crazy. I have noticed this also happens when the cover is closed and you push down on the spot where the tape is.
So this probably means the ribbon cable gets flexed too much or maybe shorts when pressure is put on the back of the tablet.
Put a little piece of platstic right under where ribbon cable comes up from the screen:
Close the cover and done!
WARNING TO READER!
This fix may not help for you! It seems there are multiple problems regarding the nexus 7 touch input. This fix worked for me and i have never had a problem since i’ve dont this little fix. If this did not work for youdont forget to take out the little piece of plactic before you send your nexus for RMA!
If this ruins your nexus 7 i am not responsible. It’s your hardware and you screwed up.
A few extra photo’s since i’m and do not actually show where the plastic part goes.
