Microsoft has started rolling out Windows 10 mobile insider preview build 15215 to fast ring yesterday. As you know that these Windows 10 mobile builds are not from the ” redstone3 ” branch rather they are from the ” feature2 ” development branch. So there are not many changes and no addition of any new feature as well. These builds from feature 2 branch generally have bug fixes and performance improvements.
Here are the few of the changes that Microsoft has mentioned in their change log:
- They have fixed an issue where removing the headset would not move the call audio to speaker
- Improvement in power consumption and performance of app
- Notification mirroring has been fixed
These are some of the known issues in this build:
- The about page of the phone currently shows the copyright date to 2016 while it should be 2017
- WeChat may crash in some cases
There won’t be any “falls creators update” for Windows 10 mobile as of now. The future of Windows 10 mobile is still in the dark until Microsoft will tell anything to us.  If you want to download this build go to setting > update and security >join the windows insider Fast Ring and update from there.
Tell us if you find any other issues other then mentioned above.
