    i really love the new 10.5" and got a "perfect screen" ... however, two things: a) sometime it takes forever to turn it on (full start up) ... meaning... i have to keep the top button pressed for a 4 sec before it starts and b) while the apple logo appears during the start up there is for a second a brief white static flickering line on the screen.... appears only during the apple logo start up screen and very brief... random location and not with every start up (maybe every 3rd start up).

    debating whether i should return immediately OR wait for a week to see if it gets worse OR wait and use and file a warranty claim down the road if it gets worse. if it's a software issue it can be fixed but a lose display connection freaks me out (especially if it goes south post warranty)

    anybody with the same issue?

    i ended up buying a second iPad and after inspecting (it was virtually identical but without the static white line flickering during start up) - I returned the other one.

    Mine takes the same 4 second press to get it to start so that is normal. But I see no static line flickering upon start so glad to exchanged.

    Enjoy!

    Mine has the flickering white line. Do you guys think it's a software issue or a hardware issue? I might reinstall iOS this weekend to see if it'll fix the issue.

    i cleaned my ipad back to factory settings before returning it and the flickering was still there. definitely a hardware issue IMHO ...

    Did you clean/reset the iPad or did you reinstall iOS with iTunes? 2 different things...

    Just reset to factory. The second one was fine so didn't feel the hassle to play around more

    Just to chime in,

    I bought a 10.5 model past Monday (256, Cell+Wifi).

    When starting up, it would show a line in a very pronounced way like described here.

    Incidentally, that was not the only weird thing: when using the Pencil for handwriting in apps like MS OneNote but e.g. also the Nebo app, which shows a dedicated Pencil dialog on first install, any inking done would result in very jagged lines.

    I have posted my findings on Ask Different and MS communities prior to finding this thread.

    In summary, when I compare strokes by the pencil in OneNote between my original 9.7 inch iPad Pro and the new 10.5 inch model, using the same pencil, with a well attached tip and using the same note, lines written on the 10.5 would be choppy, wavy whereas on the 9.7 everything looks very natural.

    The effect is shown in following images: first the Old iPad:

    [​IMG]
    Next the new one:

    [​IMG]

    Some might say 'oh but these are large zooms' but on the devices itself, even at 100% scale, you can immediately tell the text written on the new device is looks 'off'.

    Another nice example:

    Screenshot 2017-06-23 14.22.57.png

    In the pencil test dialog of Nebo, things were even worse:

    [​IMG]

    With that final image, please note it only happens in the first dialog Nebo throws at you after installing, i.e. the 'test your pencil' dialog. Inside the actual app, a lot of stroke smoothing is applied anyway so there, everything again looks fine).

    I accounted for all potential sources of this that I can control:

    1) Checking the pencil is fine, even installed a new tip
    2) Resetting the device, resetting OneNote
    3) I went on the exchange the iPad
    3) In some apps like Apple Notes, Goodnotes and Notability, everything is as before (no shaky strokes).

    Now this is where it gets interesting:

    The new iPad also shows the 'startup line' but less pronounced.

    It also has the same pencil issue but ... less pronounced.

    I do not wich to cause a stir but this seems odd.

    At this moment, it could be many things:

    1) An actual HW issue
    2) An issue where, given the re-vamped display, pencil polling or latency or whatever changed in such a way that handling pencil data in apps needs to be updated in some cases (a lot of processing needs to be done by apps on inking data if you check the iOS API docs).

    I would love to hear from other 10.5 users on their experiences here: particularly if they see the same inking behaviour in OneNote.

    So I did not mean to hijack this thread but the issues with the lines was also so apparent and correlates with the extent of the inking issue I am seeing that I thought it might be worth mentioning here.

    @KrisJa - try to narrow down the issue to hardware versus software by using the native Apple Notes app instead of OneNote.

    @masotime : My post mentions that the issue is not apparent in Apple notes.

    However, that might not be a reliable test as it is unknown whether the strokes that are recorded in certain apps are, or are not, filtered by the app somehow. You can see examples of this in this webpage for programmers on handling pencil input.

    The only reliable test would be to use an actual 10.5 device with the OneNote app...

    Also, interestingly, and before anyone brings it up, the demo devices in the store all run an old version of OneNote (15.27 - 160930) vs the most recent App Store build (16.2.1 - 170616). Here again, handling of pencil input might have changed between versions so it is again not a reliable test.

    None of the demo units have the issue in that old version of OneNote.

    So again, any 'real-life' testes of the latest OneNote with a 10.5 device would be nice to hear about.

    I reloaded iOS with iTunes and my issue has been resolved

    Edit: nvm... it still flickers. Guess I'll get AppleCare just in case it gets worst. The screen is good tho. Just don't want to get a replacement with a bad screen

    @clxa38 Would you mind running OneNote and checking the other issue I mentioned? Seems like nobody here is able to :s
