What are the known issues in Windows 10 Mobile build 14356?

As you know that, the fast ring builds are delivered from the development branch and hence there is a possibility of issues which are already known/unknown. The build is to provide you an option to try out the new features/improvements and fixes to give Microsoft a heads-up with the new changes and/or to report problems. Insiders are doing this from the first day. If you are one of them, try this build too and experience the new changes ahead of other users. If you are keen to be interested on going with a stable build, move to slow ring or release branch. Here's the list of known issues currently available in this Windows 10 Mobile build 14356:

  • Microsoft is still continuing to investigate battery life issues impacting certain devices. Already they fixed a few bugs that improve battery life but are still working on it to further improve the battery life.
  • Microsoft is investigating data issues with some Dual-SIM devices where cellular data doesn’t work correctly with a second SIM. Several issues relating to cellular data with Dual-SIM devices have been reported by Insiders with the last two Mobile builds and they are investigating these reports.
  • In some cases, the new Cortana features highlighted above may not work. Restarting your phone should fix the issue and get the features working.
  • After installing this build, you may notice your Quick Actions icons are not in the same order. This is a side effect of the fixes/changes we made to Action Center. To re-arrange your icons to your preferred order, just go to Settings > System > Notifications & actions > (Quick actions) and touch, hold and then drag to re-arrange icons to whatever position you want.
