    As mentioned in this thread that a field test app gets installed during the out of box experience.
    https://forums.windowscentral.com/microsoft-lumia-950-xl/479624-cannot-select-time-zone.html#post3761751

    When I initially got the L950 XL, only a handful of LTE bands were selected in the app. However I don't have that screenshot and I was able to pin the app to the start screen. But with the new store update you can't.

    However, we can now share the app so without further ado this is the link to the field test app: https://afflnk.microsoft.com/c/15922...2F9NBLGGH2NWH2

    So this means we can pin a custom tile using a tile creator app and pin the "website" for easy launching.

    Now what does this app do exactly?

    Well, it contains a tonnne of data which I will not posting except the relevant screenshots (as they contain very key identifying information - therefore i would suggest no one posts any screenshots about their phone other than the default bands that are ticked off or not).

    Installed during OOBE:

    Field Test App:

    The last box at the end is for SIM related parameters, however what we really need is band locking and system info, the latter is to only confirm if VoLTE is indeed supported.

    The former - Band locking is the most important as it confirms what bands are supported by your phone, the ones you can enable or enabled by default.

    As you can see by default, Band 41 is disabled for me which I enabled - Just incase Microsoft wishes to remove our access to this very erm "engineer" focused app lol.

    There is an earlier version of the field test app too. Came on the Nokia models and some of the earlier Microsoft Lumias. You can add that one too to your upload if you want. Let me know if you need that package.

    Edit: Actually, I wonder if this one from the store determines the version needed and installs the needed one automatically?...realizing this is the one from the store, and not your personal down load lol...
