Microsoft recently released another build (10149) of the Windows 10 Mobile Insider Preview, and it introduces a number of important features and improvements. Curious to see what Microsoft’s next big update has in store for mobile users? This is the build to try—and you can upgrade directly to this build without flashing your phone back to Windows Phone 8.1 if you’re still running Build 10080.

Among the new features, Build 10149 includes general UX improvements, updates to Cortana, the ability to automatically upload photos to OneDrive, and Microsoft Edge, which is the company’s exciting new browser. Unfortunately, all your bookmarks, cookies and favorites in the previous Project Spartan app will be lost, so be aware before updating.

The update to the Microsoft Edge branding is mostly just for the name swap; Microsoft also moved the address bar down to the bottom, which the company said was done based on feedback from the community.

Otherwise, there isn’t anything terribly new in the latest Windows 10 Mobile build. Microsoft urges users to check the Store Beta to download the latest updates for apps—updates for things like Outlook Mail, Calendar, Movies & TV, and more, which are all being updated independently by Microsoft in an effort to get new builds out to users.

Below is the list of fixes and known issues in this latest build. Windows 10 is scheduled for a July 29 release, though the final mobile update isn’t expected to hit until later this year.

Here are some things we fixed
  • We have fixed the issue first reported with Build 10051 where Call + SMS filtering would not work after upgrade.
  • We have fixed an issue where text notifications weren’t appearing for incoming messages.
  • We have fixed an issue where the Podcast app wouldn’t work.
  • We have fixed some issues where apps were having trouble installing or updating via the Store Beta.
  • We have fixed an issue where the navigation bar couldn’t be hidden.
Here are some known issues
  • Some people may encounter an 80091007 error trying to upgrade to this build from Build 10136. If you hit this error, sit tight – we’re working on a fix. Or if you want the new build right away, you can use the Windows Phone Recovery Tool to go back to Windows Phone 8.1 and then upgrade to Build 10149.

  • The Insider Hub is removed in this build. Don’t worry, it will be back in future Insider Preview builds.

  • Sometimes the PIN keypad won’t be shown after swiping up to unlock. The workaround is to swipe down to get to Action Center and try to open a notification or Settings to invoke the PIN keypad to unlock your phone.

  • There is a very rare situation where you are unable to unlock your phone after entering your PIN and it keeps letting you type even though you entered your pin correctly. If you hit this – leave the phone alone 1-2 hours before trying to unlock again. This is caused by a TPM issue that could get worse and require you to reflash if you get into this state and power off the phone.

  • If a Gmail account is set up on the phone, the Messaging app may have issues and both incoming and outgoing messages may not work. If this issue is hit, simply reboot your phone to get it working again. We are aware that the Messaging app may behave badly in this state.

  • There is a known issue where apps or games are installed as trial versions even though you have previously purchased them. In-app purchases on Windows 10 Mobile are not functional yet as we migrate the function to the new Windows Store.

  • In certain cases, the colors in some apps may appear off. For example – the titlebar in the Outlook Mail app is orange.

  • There might be some cases where notifications in Action Center appear blank.
