    Been having murder with my iPhone 7 the past few days, freezing, unresponsiveness, whole springboard vanishing leaving me with nothing but a wallpaper, apps refusing to open when pressed (they don't crash, they just flat out don't open).

    Looking through the crash Logs I've found multiple labelled "DumpPanic". I'm no developer, but I've always known regular panic logs to be bad news.

    Can anyone here shed some light on DumpPanic? Probably means a Genius Bar visit, just looking for a second opinion.

    Already done. No noticeable improvement sadly.

    Could you elaborate on your various 'symptoms'? Particularly on when the SpringBoard disappears and when apps don't open. What were you doing before the issue occurred, or is it sporadic? Does a reboot fix the issue? Do you have any third party apps installed (including those requiring you to install a profile to install)?

    Well, basically:

    1. Opening Mail, then attempting to 3D Touch OR regular tap on an email to preview it would see the email change to grey (letting you know its been tapped) but doesn't actually open. The app then freezes entirely until force closed. The same happens in Messages.
    2. After the above happens, tapping on ANY app icon on the home screen would see the icon change colour, indicating its been pressed, but the app won't actually open. It's as if the system is trying to open the app, but can't and decides to give up on the action. This also happens on its own occasionally, without the first point occurring.
    3. After point number 2 happens, within a few seconds, the whole system ui disappears, leaving me with a blurry background wallpaper (I've uploaded an image to the post showing what I mean). When its in this state, nothing responds except for the physical buttons, no notification centre, no control centre, there's no icon to press on the home screen, and notifications don't come through. This state can't be fixed without a force restart.

    I've attempted to Update from recovery mode to avoid the hassle of setting up as a new phone, but the problem remained. I then did a complete restore from Recovery, and set up as a new device. Even after this, the DumpPanic files appeared again.

    I've done some research to find that DumpPanic is the process by which the system dumps a Kernel Panic file into the Analytics for diagnosis. What I can't find however, is if this means the phone is actually having a Panic, or is just flirting with one. There's no actual Panic.ips in the Analytics yet, which is something good at least.

    I've had a similar problem as well, never happened before with my still newish iPhone 7 plus only since the last ios update...could be a software issue?? Hard rebooting always solves the issue though.

    There are a few things that may be derived from your symptoms:
    1. Persistent software bug that's device related (not iOS's fault)
    2. Some sort of issue with the 3D Touch module
    3. Data corruption with the storage chip on-board your device
    I highly suspect it's an issue with the 3D Touch module (or the touchscreen per say) because the touch response stops working after the issue occurs. I say this because the symptoms you described require the touchscreen to trigger. If full restores don't do the trick, I'm afraid you'd have to get it checked out or replaced at an Apple Store or Apple Certified Service Center.

    P.S. You may want to try pushing with a little force on all 4 corners of your screen. I have no confidence in this method, but it's the only thing I can think up of.

    I had suspected this too, however the issue also occurred when 3dtouch was not used. I'll book it in at the bar this week for a check up either way. Its worth noting that Ive been using a 7 plus for several months with none of the above issues, and they began showing up within a month of restoring my backup to a 7.
