We earlier reported about two GDR updates lined up for Windows Phone 8.1 with Windows Phone 9 targeted for end of 2014 to early 2015. GDR2 especially seems more interesting as it has been tipped to add some “broader hardware support”.
Now, we have some more info about this and as per our sources, GDR2 may add support for 2K resolution display and Snapdragon 805 processor. Seems, Windows Phone 8.1 has support for only two new resolutions QHD 960 x 540 and 854 x 480 and up to Snapdragon 800 in processors. But, if the tip has to believed, next Windows Phone 8.1 Builds are already getting tested with 2K resolution display and Snapdragon 805 support. We caught one such device on GFXBench sometime back.
The rumor is also that GDR1 will just be bug fixes and so on, no new features which would explain how/why it could come quick.
