Chassis Requirements for WP8.1 GDR1 revealed

Microsoft’s OEM dev site continues to be a rich vein of information to mine regarding the next minor version of Windows Phone 8.1, GDR1.

The latest to arrive is the Chassis Requirements for handsets running the OS. Most of the features remain unchanged from earlier versions of the OS, but there are a few surprises.

One of them is that Windows Phone now supports qHD resolution (960 x 540) scaled from 720P. The OS still does not support the newer super high resolutions however, being limited to Full HD (1080p)

Also interesting is that a proximity sensor is now a hard requirement, surprising given that the Nokia Lumia 630 and 530 does not feature one.

Also unfortunate is that there does not appear to be any support yet for the newer Snapdragon 810 processors.

Microsoft has dropped performance requirements for MicroSD cards in WP8.1, and can compress the OS partition to enable more free space in 4 GB handsets.

See the full list of specs after the break.
