As promised, on June 16, 2015, Microsoft is rolling out Windows 10 Mobile build 10136 to the Fast ring of update. The new preview of the operating system for mobile devices brings a number of new features and enhancements over the previous build, such as new tweaks in the users interface, Cortana and built-in apps improvements, fixes, and a lot more.

However, Microsoft explains that build 10136 isn’t completely ready, there is one bug that causes the upgrade to fail for users upgrading from Windows 10 Mobile build 10080, as such the company is only offering the new build for phones running Windows Phone 8.1 and have configured to receive new builds from the Fast ring of updates.

The software maker advise any Windows Insider that wants to try the new build to roll back to Windows Phone 8.1 using the Windows Phone Recovery Tool first. Then users can download the Windows Insider app from the Windows Phone Store and configure the phone to the Fast ring of updates again.

“This is required because of a migration bug affecting upgrades from 10080 to this build so we are not supporting that upgrade path.”  Microsoft explains.

Of course, if you’re already running Windows Phone 8.1, simply install the Windows Insider app, register as an Insider, and configure the phone to receive new builds via the Fast ring.

In addition, Microsoft says that it’s supper important to note that after the upgrade is done, the Lock screen will appear frozen without date or time. The workaround is to simply wait for about 10 minutes until you see the time and date again, then you can unlock your phone.

Here is what’s new in Windows 10 Mobile build 10136

Now that you know how to upgrade your phone to the latest build, let’s look to the new changes and enhancements Microsoft is releasing with this build:

User interface changes: In build 10136 there are a number of subtle UI changes, among them, you’ll find the PIN pad is no transparent and slides up over your Lock screen images instead of displacing it. There are new fonts, icons, and new layouts, and overall the operating system feels more complete.

Cortana: The team has made tweaked the cards in Cortana’s homepage and in the hamburger menu. There is also a new dark theme make it feel more integrated into the operating system. In Windows 10 Mobile build 10136, tracking flights and packages has been enabled, so you can track this kind information as soon as new emails arrive. Now alerts work, going home and the airport are also enabled again. Additionally, you can ask the digital assistant about weather, current information, stock quotes, and more.

Photos and Camera: There are also a few new changes in the Photos app, tap on a month to get a list of months and jump to photos taken in past. You can double-tap to zoom in a photo, and the app also includes a number of performance and reliability improvements.

If you’re running build 10136 on a Lumia 640, 640XL, 930, Icon, or 1520 make the Lumia Camera Beta your default camera app. Microsoft explains that the Lumia Camera Beta is the same app as the Windows 10 Camera app, but with additional features for Lumia devices.

One-handed use: For users using a phone with a 5-inch or greater display, Microsoft is making easier to use the phone with one hand. Press and hold the Start button and the screen will slide down to reach items at the top of the screen. To slide the screen back up, tap the black space at the top of the screen, or press and hold the Start button on more time. (The company warns that the new feature take a few tries before you can get used to it.)
