Along with a list of what's new and improved in the just released Windows 10 Mobile preview build 10136, Microsoft's Windows Insider head Gabriel Aul has offered a list of what fixes has been put in the build compared to the older 10080 version. There's also a list of what issues are still around with this build.
Here's what Aul says has been fixed in build 10136:
- 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.
Here's the list of issues that some users might encounter when using build 10136:
- After upgrading, you will still see duplicate tiles for apps like Search and Phone under All Apps.
- If you have too many PIN unlock attempts, you'll see the "enter A1B2C3" reset experience. However, there is an issue in this build where after you enter the code you won't see the PIN pad. The workaround is to press Emergency Call after entering the code, then press Back and you'll be able to enter your PIN.
- We recommend disabling the double-tap-to-wake feature on some Lumia devices by going to the Settings app then Extras > Touch > Wake to prevent any accidental PIN unlock attempts.
- There is an issue that may cause Skype not to work after upgrade. The best workaround is to uninstall Skype on Windows Phone 8.1 before you upgrade to this build and then reinstall it after upgrading. If you miss that step though, you can usually resolve by uninstalling it and reinstalling from the Store once you're on 10136. If you're having issues installing new Language Packs in this build, see this forum post.
Keep in mind that for this build, users will have to have Windows Phone 8.1 installed on their smartphone in order to get this newest build, and that people with the older 10080 Windows 10 Mobile preview build will have to downgrade to Windows Phone 8.1. Aul says:
"The upgrade experience is something that is very important for us to get right, so you should definitely expect that we'll address the migration bug that affected this build. In general, we expect that you should be able to upgrade build to build without having to flash back to 8.1."
