Microsoft is working at full speed on improving Windows on PCs, but on the other hand, interest in revamping Windows 10 Mobile seems to be dropping just as fast, with every new build bringing only boring improvements that can barely be noticed even by hardcore fans.

Living proof is Windows 10 Mobile build 15228, which was officially rolled out today with a bunch of fixes, but with no new features.

The company hasn’t even provided a list of known issues, and this obviously doesn’t mean that no bugs exist in the operating system, as there still are lots of problems that need to be addressed before Windows 10 Mobile can truly be considered a stable platform.

What’s new in Windows 10 Mobile build 15228?

The new build 15228 comes with a fix for notifications, including SMS and calendar, experienced with Fitbit trackers, as well as improvements for the Bluetooth connectivity with Garmin wearable devices.

Microsoft says it has also fixed crashes reported while using the Photos app, as well as a bug impacting email accounts and reported in the previous builds.

“We have fixed a deployment issue in where if an admin uses ActiveSyncCSP to provisioning email account on device running the Windows 10 Creators Update without providing a valid password, and the email server enforces a limited number of denied access retries, then the server will lock out the email account,” Microsoft explains.

Windows 10 Mobile build 15228 also improves battery performance, and it’s all thanks to a fix for a bug causing Camera app preview and capture mode to eat up 30 percent more power than they should. And last but not least, there are also fixes that should make it possible to play video in landscape mode without any issues.

All in all, this is just a bugfixing release, and as far as new features are concerned, nothing is confirmed so far, which leaves us hoping that there’ll be a day when Microsoft kicks off the highly anticipated overhaul with new features and improvements across the OS.
