Today, Microsoft released the first Redstone build of Windows 10 Mobile to the fast ring, build 14267. As Microsoft promised, the new build is only available to the Xiaomi Mi4, Microsoft Lumia 550, 950, and 950 XL.
The new build did come with its fair share of new features; however, before you take the plunge into those new features, you're going to want to know the risks.
There's only one known issue for the build. Oddly enough, there are seven things that were fixed. One would think that the fixes would be reserved for a cumulative update.
Without further delay, here's what got fixed and the known issue for Windows 10 Mobile Insider Preview build 14267.
Here's what got fixed:
We fixed an issue where shape writing would ignore every second word when typing into a text box on a website in Microsoft Edge.
After installing the Polish keyboard, typing a word that should be accented now offers the recommended accented word. For example – if you type the word “milosc” it should properly autocorrect to “miłość”.
We have resolved an issue where you could not hide the navigation bar in Windows Phone 8.1 apps like WhatsApp, Twitter, Weibo, Flixster and others.
We fixed an issue where videos recorded onto SD memory cards would result in a large number of dropped frames.
There should be improved app launch reliability and certain crashes that were causing the phone to reboot are also fixed.
We’ve polished the Live tile animations and improved the logic for refreshing Live tiles.
We’ve made reliability improvements for keyboards with large dictionaries such as the Hinglish keyboard.
Here is the known issue:
Visual Voicemail notification and delivery is not working in this build; causing devices to not receive any new visual voicemails. You can manually check your voicemail by calling your voicemail to listen to any new messages. You can call your voicemail within the Phone app by clicking “…” > Settings > “Change more settings for Phone” > “Call voicemail”; this will also leave the Voicemail call in your history to make checking voicemail easier.
Update: Gabe Aul has updated the post an additional known issue that Lumia 550 users should take note with, Microsoft is recommending that you skip this build, if however you have already upgraded, there are a couple of workarounds you can try to recover.
ADDED 2/20 – Several Windows Insiders with a Lumia 550 have reported an issue where their phone no longer charges or connects via USB after upgrading to Build 14267. If you have a Lumia 550, we recommend holding off going to this build. If you have hit this issue we recommend rolling back to Build 10586 using the Windows Device Recovery Tool. You will need to connect your phone to your PC via USB first, open the Windows Device Recovery Tool and choose “My device was not detected”, choose “Lumia” and turn off your phone and let it reboot in order for the Windows Device Recovery Tool to detect your phone and reinstall. If you need to download the image, your phone may reboot back into the OS, once the image finishing downloading completely – reboot your phone again and it should begin reinstalling Windows 10 Mobile.
If your Lumia 550 is really low on battery, switch your phone into flashing mode by turning your phone off first and press power button and then volume up until you see a lightning bolt on your phone’s screen. This will allow your Lumia 550 to charge. You should let it charge a bit before using the Windows Device Recovery Tool to roll back to Build 10586.
