Note: Although some 'XL' owners in Europe have the update too, my UK unit doesn't. Anyway, be patient if you don't see this yet, it's a err.... 'roll out'(!)
The new firmware update today is distinguished in the second number block by '00053', e.g. 01078.00053.16236.35017. A reminder that 'firmware' in this context is low level code that sits between the chipset microcode and the main operating system (i.e. Windows 10). Think of it as device drivers, software that interacts at a low level with the hardware in your smartphone.
The improvements in this release include:
- Wi-Fi connectivity improvements, including fixes for Wi-Fi connection dropping randomly and a Wi-Fi scan occasionally not returning any results. In truth, I've had precisely zero issues with Wi-fi, but I know that others have been less lucky. Hopefully this update will make things more reliable all round.
- Ditto for Bluetooth connectivity improvements. Again, I've not had issues, but others have had dropouts and inconsistencies with car kits, especially. This update should help.
- Support for double tap to wake enabled. This works fully as advertised and has been much requested, though do note that the necessary always-on touchscreen monitoring at a low level does mean a little extra battery drain. I'd estimate around a couple of percent a day. So it's your call whether to enable this or not. I think I'd rather have the extra battery juice, since I'm very happy using the phone's side button to power the screen on.
- 'Stability and reliability improvements'. Who knows what these involve, but less bugs is always good, so....
- Camera improvements - see below.
- Cellular connectivity improvements, including a fix for a problem that caused occasional network loss for some users.
- Audio quality improvements, including fix for a problem that caused voice call audio to get scrambled for some users.
Hopefully one or more of the above should get you excited in terms of improving your day to day use of the Lumia 950 and 950 XL.
Although the changes are subtle, here's the imaging changelog, to do with how Camera talks to the physical hardware in the 950/XL:
- The low light contrast and color capture have been improved.
- Auto-focus is significantly more reliable, also in low light.
- There's a fix for a problem that was causing slow motion capture to skip frames for some users.
Taking back to back shots (using multiple units with different firmware) that demonstrated the low light improvements proved tricky, but the example below shows the auto-focus and capture changes fairly clearly. The focussing was MUCH more reliable with the new firmware - the old software would often 'lock' when the lens position wasn't perfect.
Here's the test scene, mocked up in a corner of my bedroom. Just a small 10W energy saving lamp, use your mouse or pointer to compare the 'old' firmware with the 'new':
[NOTE: the comparator is broken as I write this. Rafe's fixing it. In the meantime, the images are one above the other etc, old, then new.]
The differences are subtle, but I did note a higher ISO (64, not 50) was used and that there's extra colour in the 'new' shot. Plus the focussing was spot on, unlike that when shot with the old firmware, which proclaimed a focus lock on the pens and glass but which turned out to be not quite perfect. As you can see if we crop in to 1:1. Again, old firmware first, then new:
Auto-focus in low light is still slower than on phones with laser auto-focus, but at least it works more reliably than it did. And hopefully low light shots will be even better, helped by the usual excellent OIS in the 950 pair.
One shame is that there's still no use of the full set of four microphones when shooting video, so I guess that'll have to wait for either a new Camera update or new firmware again.
