Microsoft released the new build 15043 for Windows 10 Mobile last week which brought a couple of new features and minor changes, which isn’t a surprise since Windows 10 Preview builds are now in the release branch of the Creators Update.
In fact, the main focus of Windows 10 Preview builds 15043 and 15042 are bug fixes and system improvements. The list of improvements in these two builds is quite long, which means Microsoft is slowly polishing the Creators Update for the public release. But, as usual, the new build also causes some issues to Insiders who install it both on PC and Mobile — and the Windows 10 Preview build 15043 is not an exception.
Microsoft warns Insiders that they won’t be able to install any speech packs on Mobile on this build. Additionally, if you want to add a new card to Microsoft Wallet, you’ll also have to wait for another Windows 10 Mobile Insider Preview build. For now, there’s no known solution for any of these issues. The only thing that can be done is wait for Microsoft to release a new build. However, since the development team is now focused on fixing bugs in Windows 10 Preview releases, you shouldn’t have to wait for too long.
