The first Windows 10 Insider Preview since Microsoft announced the Creators Update last week is now available. Build 14959 is rolling out now to PCs and phones in the Fast ring, bringing new features, and various fixes and improvements.
You can check out what's been fixed (and what hasn't) for PCs here. Before you install the new build on your Windows 10 Mobile device, you might want to be aware of the various fixes that it brings, as Microsoft explains:
- The data usage page in Settings via Settings > Network & wireless > Data usage has been updated with performance and UI improvements.
- We fixed issues preventing Insiders from adding cards to Wallet and paying using tap to pay.
- We fixed an issue resulting in being unexpectedly able to close Start in the task switcher.
- We fixed an issue resulting in certain options for default calling app via Settings > System > Phone > Default apps from being unexpectedly missing.
- We fixed an issue causing apps that play media in the background, such as Groove Music, to stop when Battery Saver turns on.
- We fixed an issue Insiders may have experienced where the phone would get into a state where copy/paste wouldn’t work until the device had been restarted.
- We fixed an issue where Settings might hang after unchecking “Let apps automatically use this VPN connection” in VPN Settings.
And you should definitely read through the known issues before installing build 14959 on your handset:
- If you used the previous ‘date change’ workaround to update to Build 14951 or Build 14955: Please don’t use it any longer! The Microsoft account (MSA) ticket on your device needs to expire and then you’ll be offered today’s build. If you changed your date by 30 years… you’ll want to do a device reset.
- You will be unable to install additional languages, keyboards, and speech packs on your phone for the next few weeks. If you have existing languages, keyboards, and speech packs installed – they will carry over when you update to new builds. You just can’t install any new ones. If you do a hard reset of your phone on these builds – you will also be unable to install additional languages, keyboards, and speech packs. You can use Windows Device Recovery Tool to go back to Windows Phone 8.1 or Windows 10 Mobile, install any languages, keyboards, and speech packs you need and then update to the latest build in the Fast ring as a workaround.
If you're not prepared to deal with those issues, you should avoid installing the new build by opting out of the Insider Program temporarily, or switching to the Slow or Release Preview rings, where you'll get more stable builds with fewer issues.
Given that this is pre-release software, and may well include bugs and problems that even Microsoft hasn't anticipated, you should always avoid installing Fast ring builds on your primary handset.
