NONE OF THESE ARE WORKING FOR ME ON CYAN. IT IS EXACTLY HOW IT WAS ON BLACK.
•Equalizer now works through the speaker – The graphic equalizer found under Settings > Audio on non-Cyan devices is limited to just headphone usage. Nokia has finally expanded this to the phone's speaker too, letting users have fine-grained control over music. Update: the EQ does not work through Bluetooth devices.
•Dolby Headphone is now Dolby Virtual Surround – Also under Audio is Dolby Virtual Surround which is explained as "Surround sound enhancement for headphones enabled only for 5.1 audio". Functionally, the two may be the same, but it does add some new features like…
•Dolby dialog enhancer – "Improves the dialog clarity for movies," which is pretty self-explanatory
•Record audio for videos in Dolby Digital Plus 5.1 – On the Lumia 930 (and possibly Lumia 1520, Lumia Icon) users can optionally choose to record audio for videos with Dolby's new 5.1 technology. Dolby Digital on the Lumia 930 represents the first time achieving this in a smartphone, and it should prove to be impressive
•Brightness Profile – Users can set the default average brightness for their phone. Unlike the Lumia 630, which has controls for all three levels (low, medium and high), the Lumia 930 has a single slider. My guess is this sets the median, default brightness
•Color Profile – With Lumia Cyan there are now three presets (Standard, Vivid and Cool) in addition to Advanced, which lets the user modify three settings, including color temperature, tint, and color saturation via sliders
•Bluetooth 4.0 LE – Some Windows Phones had Bluetooth 4.0 LE enabled with Update 3 last year, but the Preview for Developers disabled it due to changes made by Microsoft to the stack. Lumia Cyan re-enables this feature for things like Nokia Treasure Tag or smartwatches. Official apps for smartwatches and other connected devices are coming later this summer once Cyan achieves a larger rollout.
•Living Images – Also announced earlier, Nokia's Living Images briefly records a second or two before the photo gets taken. When viewing the image through Nokia Camera or StoryTeller, users can see the image animated, giving life to the memory
•Miracast support – Found under Settings > Project my screen, certain Lumias are getting full support to wirelessly stream content, or mirror the phone's display on Miracast devices such as PCs and TVs. You can watch my demonstration of this on the Lumia 630
