    the 5 screws holding motherboard are very very loosen by default this lead to weaker grounding ,just tighten them and you are done, or keep bending the phone
    I haven't opened the phone up, but the 5 screws are immediately seen once you get the phone opened up? I have a newer green Lumia 1520 and I've hit a tile a few times on the home screen, but whether it's me or the false tap is hard to determine. If I start encountering this issue more I'll open it up and use your advice. Also if you say just tightening up these screws seems to help, it might be worth it to pull the screws out and add a drop of blue thread locker to help with the fact that the phone is large and may be more susceptible to slight flexing.

    Mine is revised to 5.0.0.1. Probably a good idea to send it in for repair. They seem to be able to fix it at a good extent now.

    How long did the whole process take to have your phone sent in and returned? If not long I may just send it in. Although I haven't really seemed to encounter the issue, but I also haven't had my 1520 long. Oh, also what was your previous hardware revision?

    Also when it comes to this issue I've tried some of things you mentioned, simply just holding down a tile in the Windows central app and it never clicked on it. I've violently swiped up and down on home screen, settings, and app list. Even scrolling through forums through IE I've yet to click on a random word or zoom in. I have a Venue 8 Pro so I'm painfully aware of how a tap instead of a swipe registers. I also don't have the double tap to wake enabled. With that enabled was when I did have a few instances of hitting a random tile on my Start Screen and opening an app.

    To help deciding if there is a correlation between revision numbers and this problem, my hardware revision is 6.2.0.0. I don't have the problem but then many people of all revisions probably don't have it either.

    I would also think the hardware revision would vary based on what model you have. RM-937/938/940. On board memory, Qi, wireless bands, etc. So I would agree that there may not be much to put on hardware variation. If anything you'd think having the little bit newer Green AT&T/1520.2/RM-940/whatever you want to call it should have whatever fix unless they literally just started changing it. I would almost go with what Hesham said about the grounding and the screws being loose. I also see a lot of people talking about gap between screen and case. So I'm thinking the plastic housing is slightly more prone to flexing, over time the screws holding the motherboard may become slightly loose, and then the housing flexing a little allows the phone to not be quite as tightly fit around the screen. So now it's not all as nicely wedged together as it could be. Seeing as the pushing on the phone seems to fix things, it might then re-seat everything and kind of put more pressure between the motherboard and housing giving better contact even though the motherboard may not be tightened down as well as it could be.

    Worst case scenario I'll just send mine in under warranty if it really starts happening.

    About 3 days. I took it personally to the repair center though. My previous revision was either 3 or4.

    I'm on PFD and I have the issue all the time. I think that the glass screen protector that I have is contributing for the problem. Anyway, th problem is still there.

    I had to open my 1520 to replace the camera that was faulty. I didn't notice the screws were loosen. And I screw them correctly when mount all the part back. The scroll-tap issue is still there.

    Hardware version: 6.0.0.0

    Did you checked the grounding just near the camera module maybe you just widen the gap between main board and grounding while remounting it back

    I have noticed an increase in problems regarding tap/scroll sensitivity the more apps I have pinned to the home screen, can anyone one verify this?
    I have a selection of different sizes, small/medium and long tiles pinned.
    when I reset the phone it's all fine and dandy with all medium square tiles on start up, but as soon as I start customising the start screen with different sized tiles, the problem seems to get worse to the point where I've had enough. I took it back to the shop where I got it from and after an hour of them testing they said there was no problem with it, as soon as I get it back in my hands, well....what can I say?
    They're obviously not going to replace the handset as in their eyes it's doing fine.

    Well, I wasn't aware of this when I did the operation, maybe I'll open it again to see that, but the back plastic cover doesn't like my way to open the beast =p

    Is this grouding the piece of metal fiber glued on the screen? Cause it went back and I had to use some light glue to maintain it while mouting back the components (sorry for my approximated English).

    I can try to replace it with one more thick if I can find that kind of tape.

    I removed my screen protector yesterday and havent had any swipes register as taps since then. For sure iremoving the protector has affected my device.

    I personally dont think my device has a hardware problem, I think its software related making the screen too sensitive. I hope it gets fixed in Denim, if it doesnt, it never will. I went to Nokia Service center yesterday to talk about this. I asked them is this a known issue, they claimed not. They said bring it in and they will check it out. They said if it needs to, they will use the device for days, to see and confirm the problem and if its there they will fix it.

    I dont know, I thought I will wait for Denim and if its still there I probably will take it in. Although like I said before, I havent had any since removing the screen protector.

    EDIT: HW revision 5.0.0.1

    I see a similar issue on my HTC One, though admittedly not to the same extent. I'm not convinced there's really an issue, or maybe I'm just not understanding what the issue is.

    I have already read the explanation in this topic a few time, but since my phone is not opened and the photo of the service manual is not really clear, I was just wondering if it could be this piece of (grouding?) tape I had hard time with when assembling the parts. I'll see when 4ill open it again. And if the problem is just a gap, is it impossible to put some piece of paper on the other side of the motherboard like a wedge that will work as if the phone was bending in the good way? I'll try this.

    I do a new post rather than editing the previous one to bump it out since I maybe have found a solution.

    First I checked the good contact between the LCD grouding and the motherboard by putting some piece of paper behind the contactor. But I still had the sensitivity issue.
    So I looked more precisely at this lcd grounding component. I find out it also connect to the back of the camera. Since there are different pin to connect to the motherboard and to the camera, and reading some electrics arc could happen between the camera pin and the motherboard metal piece used to do the contact, I used tape to isolate the part of the motherboard where the arcs could land:

    http://forums.windowscentral.com/att...lcd-ground.jpg

    So I just put (plastic) tape on the previous selected area.

    The screen scrolling of my 1520 is now really smoother, and I can play Secrets and Treasure without firing bullet in space cause of false touch (that was nearly impossible to finish my daily playtime without having this issue before). I still did not have any issue with the Windows Central app (which happened a lot before) and the scrolling is now as smooth as on my lumia 920).

    I'll change the tape for electrical tape next time and will cover more accurately the area, because I did not cover the edges and it could be the source of the really rare sensitivity issue I have now.

    I use high sensitivity touchscreen setting and glance background since I did not see any differences while activating them or not.
    (Note: since the paper wedge bent my connectors, I was forced to let them in place, but I think it's useless if your connector pins are not bent in the wrong way).

    PS: I apologize for my English, I did my best.


    EDIT: It lasted 5 days, now the ghost touch is back.
