    After a complete wipe/reflash/upgrade it's better but still there. Certainly at this point it is good enough that I'm willing to overlook it for the most part but all I have to do is spend 5 minutes with my Wife's 1020 or my 822 (which is a media player/remote these days) and it's not to hard to figure out that the 1520 still isn't completely there yet in this regard.

    I tend to agree with those that feel this was some kind of fundamental hardware design issue and that while the firmware/software updates have brought it a long way, I'm not expecting it to ever truly be 100% fixed.

    Thank you guys!

    When the Cyan-Update is available in Germany, I will install it with the Nokia Recovery Tool and if the issue should still be there, there will be trouble between MS and me.

    Can I validate that I am having the same issue as others?

    My "random tap issue" is the screen just starts to go crazy, lots of taps, scrolling, and capacity button clicks(can feel my phone vibrate like i am hitting one of the three buttons). Cortana will come up, start screen will display, and the multitask display will come on. Just seems like a thousand fingers are touching my screen.

    My biggest issue with this is it hangs up my calls, or hits the hold button if I take it away from my face at all. Really is annoying. As far as people thinking this is a hardware issue, I didn't have this issue before 8.1, maybe others did. This phone was perfect before going to 8.1 DP, and now 8.1 on AT&T.

    Sometimes my phone locks up when trying to unlock and I assume it's the same issue. Too many things "touching" the screen making the phone appear to be locked up. To me, it's all the same issue.

    OMG... That sounds crazy, man! Please make a clean install with the Nokia Recovery Tool.

    I did a clean install before updating to 8.1 RTM. I used the recovery program to go back to 8.0, then upgraded to 8.1. Then did another hard reset after upgrading.

    What I haven't done is rolled all the way back to 8.0 for any length of time to see if issue went away. I assumed I was having the same problems as other talking about screen issues so I want to confirm before I spend time troubleshooting or if I need to go trade this one in for a new one. I purchased the warranty from the MS Store but I don't want to trade it in just to trade it in.

    Is it not possible to make a clean install directly with 8.1?

    The Cyan update seems to be sensitive on how it is installed. I have tried several ways, but the one that works the best and gets rid of screen sensitivity, lag etc.. completely is this:

    1 - Downgrade to WP8 using Recovery Tool. Don't use any backups.
    2 - After setting up the intitial WP8 (MS account etc) DO NOT HARD RESET...
    3 - Go to Settings and turn on Wi-FI for when screen is off. Do not touch any other settings
    4 - Update to Cyan OTA
    5 - After the update, when on the final screen asking about Advertising ID, Update Store apps etc, the phone should automatically restart before you can do anything. I would wait on this screen before pressing 'Done' to see if this happens.
    6 - DO NOT HARD RESET!!!
    7- Also make sure you don't use a backup. Do a fully clean install.

    Both times that I have done this the phone has been superb. No lag, problems or screen sensitivity issues.

    I think the critical step is the restart after Cyan has updated. It didn't happen every time if I set up WP8 fully. Any time the restart didn't happen the screen was not good and the lag was noticeable... This may be a bug in the Cyan set up process. Who knows, but my 1520 is nigh on perfect after doing it this way. I have done it this way twice and both times the restart happened after Cyan was updated. Which I think is the critical part...
    Any other method doesn't seem to work as well... Phantom taps etc

    Hope this helps and you get the same results!!!

    I did a hard reset and I don't have a screen issue. I wiped after downgrading.

    Great that the hard reset works for you. In my case the hard reset method introduced all sorts of screen problems and lag.
    The method I outlined hopefully will help those who are still getting problems even after a hard reset.......

    Can't guarantee it will help, but I hope so!!!! Just seemed strange that doing it that way made the phone restart automatically with all problems gone afterwards....

    Installed the Cyan update straight from 8.0 today. I had the restart mentioned in Step 7 of Geddeeee's post. I'm afraid the swipe/tap/scroll but is still very much alive and well on my device . Such an incredibly awesome phone otherwise.

    Oh well, I knew this was a hardware issue the entire time, so I didn't have my hopes up. Thanks for trying, Geddeeee!

    That's a pity... Silly question: Did you also let the store update all the system and apps after the install? Maybe clutching at straws, but you never know!!!

    It seems that the problems with the screen on the 1520 is variable from device to device, and not easy to replicate. Maybe that is the problem that MS is facing.

    Last resort... Try a hard reset and see what happens???

    I have the same problem. Did not understand the third point. How can you turn on Wi-Fi when screen is off ?

    I've had my 1520 for two days now with a fresh install of AT&T flavor Cyan/8.1 and have run into the ghost touch a couple times. It generates a tap instead of an intended swipe. Very annoying!

    The default sensitivity setting for the 1520 is set to high. Try changing it.

    I also had the restart and I did let update all the apps, but the touch-issue is still alive. I will contact Nokia/MS today, that is very frustrating.

    The 'phantom tap' issue makes no difference if it is High or Normal..

    WPCentral posted this recently regarding Lumia1520 issues including the screen sensitivity issue:

    My hope is the forthcoming Lumia Cyan firmware update finally straightens out those quirks, which to me seem like calibration issues, and nothing dire.

    (From Following New Article): Here's why the Lumia 1520 is still my favorite Windows Phone | Windows Phone Central
    I submitted a news tip a while ago linking to this thread, saying that the issue is still present in Cyan. It doesn't seem like WPCentral considers it newsworthy, as I haven't seen anything on the main page. It's a shame because the more press the issue gets, the more likely it is to be addressed or at least commented on by Nokia
