A little bit of background work – OS 14157 happens to be Windows Phone 8.1 Update 1, which means users need not have to enroll with the Preview program. Apart from that, this would make the Nokia Lumia 930 similar to the HTC One for Windows on Verizon, being an official, non-preview handset to be on the receiving end of Windows Phone 8.1 Update 1.
Among some of the improvements where one can expect include better stability and performance, enhancements to its imaging capability, an enriched display performance, Cortana support thrown into the mix for those living in UK and China, Start screen folders, a customizable snooze for the alarm clock and other usability improvements. Do bear in mind that this would remain as the Lumia Cyan update, and it should not be thought of as the Lumia Denim.
