    Hi everyone,

    I'm using a double SIM device, and I set my setting is automatically updates new update and builds. Last year, I was very happy because of a build with a great function of Phone app: vibrate when the call answered, and most of apps run smoothly. It seems build 10549

    But in next build till now, that function was removed for double SIM device, and now I meet some issues with other app (viber, weather, evernote..)

    So, can anyone help me to solve this? Can I reinstall a previous build of Windows 10 Mobile? (like 10549 )

    Thanks and regards :)

    No you can't. You can only install builds that current in terms of their built rings:

    * Fast
    * Slow
    * Production

    The production build is only applicable for phones that were originally sold with Windows 10 Mobile pre-installed.

    Hacking a build from any other source isn't recommended as there's no way you can trust the contents of that image and there's no way of knowing whether you'll receive any further updates.
