Microsoft has just made Windows 10 Mobile Build 10136 live now. Only thing you need to do is to roll-back to Windows Phone 8.1 using WPRT, if you are already running Build 10080 on your devices. If you have followed our coverage and already rolled back to Windows Phone 8.1 then you are all set to go. Launch Windows Insider app and choose “Insider Fast” from options and then check for updates.

Build 10136 official changelog:

Here is what’s new

Tons of fit and finish changes: There are far too many subtle changes in the UX to cover. You’ll notice some obvious ones right away, like the PIN pad is now transparent and slides up over your Lock screen image instead of displacing it. You’ll see many changes to fonts, icons, layout, etc. and the UX will feel more complete than what you used in 10080. We’re doing a lot of refinement to the UX right now and you should see more of that work in the next build we flight.

Improvements to Cortana: Cortana’s experience has gone through a rich set of improvements and is now very close to our final design. We’ve made adjustments to cards in Cortana’s homepage and in the hamburger menu. We listened to feedback from Windows Insiders and added the dark theme colors to Cortana’s UI to make our UI more cohesive with the rest of the OS. Tracking of your flights and packages has also been enabled so whenever you get an e-mail with flight or package information they show up in the Cortana experience and Cortana will also alert you about them. Alerts for going to work, going home and the airport are also enabled again. Further you can ask questions to weather, currency information, stock quotes and more and get the answers directly inline. That makes it easy to quickly check on multiple locations or stock tickers. To explore further and get the full experience you can tap on these results.

Photos and Camera improvements: In the Photos app, tap on a month to get a list of months so you can quickly “jump” to photos you may have taken a while ago. You can also now double-tap to zoom on a photo. The Photos app also comes with performance and reliability improvements. If you’re running this build on a Lumia 640, 640XL, 930, Icon, or 1520 – check out the Lumia Camera Beta and make it your default camera app. The Lumia Camera Beta is the same app as the new Windows 10 Camera app but with additional features that light up based on Lumia hardware. Let us know what you think!

One-handed use: if you have a device with a screen of 5 inches or greater, it’s now easier to use your device with one hand. Press and hold the Start button and your screen will slide down so you can reach items at the top of your screen. To slide the screen back up, tap the black space at the top of the screen, or press and hold the Start button again. One-handed use will also naturally time out after several seconds and return to your regular view.

We’ve fixed some issues from Build 10080:

  • We have fixed the MMS bug in Build 10080, and you should receive MMS messages normally.

  • We have fixed the issue where touch will stop responding on the Lock screen preventing you from swiping up to unlock your phone.

  • We have fixed some visual glitches in Action Center when expanding/collapsing.

  • We have fixed the issue where the text in the People app was too small.

  • When you toggle the Wi-Fi quick action in Action Center, it now disables/enables Wi-Fi instead of taking you to the Wi-Fi Settings page. This was one of the top 5 pieces of feedback we heard from Windows Insiders.

  • Your Start screen background should be scaled correctly now.

  • You can add a detailed status to display on your Lock screen from apps like Outlook Calendar without having the Settings app crash.

  • We also fixed the issue where a mouse cursor would appear when pressing the back button on your phone.
