Microsoft has been hush-hush about Update 2 for Windows Phone 8.1, the second semi-major update for the operating system. The reasons should be obvious as the company is instead putting all resources on Windows 10 Mobile, which is the real future of the OS.
As a result of this priority shift Update 2 (aka GDR2) is only going to select phones as an upgrade. So far, the only Lumias confirmed as getting updated are the Lumia 735 and Lumia 830, while the Lumia 640, Lumia 640 XL and LG Lancet ship with the newer OS already installed. The HTC One on Verizon and BLU Win HD LTE also have been updated.
So what is in Update 2? Microsoft has now published the changelog on their support site. However, it is not the whole story, so we will add a few more things that have been found in using the upgraded operating system.
Windows Phone 8.1 Update 2 (Microsoft)
As far as build numbers Update 2 starts at Build 15127 and so far goes up to Build 15148. These other additions have been observed by users as being a part of Update 2.
There are also likely under the hood fixes and adjustments as the performance. Even on devices like the Lumia 640 Windows Phone 8.1 seems to be very efficient when compared to Update 1.
There’s no word on when the Lumia 735 and Lumia 830 will get the updates, as some GB/UK and French versions are already receiving the new OS. Owners of those devices can check for updates under Settings > Phone Update or consult Microsoft’s support page to see if their phone is getting build 15148 or later.
As to why Microsoft is not pushing this update for the Lumia 1520, Lumia 930 and other devices, our guess would be the company focusing resources again on Windows 10 Mobile. It is not clear why Preview for Developers is not being utilized either, although it now seems clear that that program is now retired in favor of Windows Insider.
