So, second preview build for Windows 10 for Phones is live now and we posted the official changelog and list of supported phones. Time to talk about some known issues with the Build 10051. In case you are still undecided about joining the Windows Insiders it is better to know about the issues first.
This is preproduction software going out to the Fast ring – so you should expect to see some bugs. The list below are some of the ones that we thought you should know about up front, and it’s worth reading carefully. We’re working to fix all of these in future builds.
- There might be situations in which auto-upload of your Camera Roll to OneDrive may not be working. Please be sure to back up your photos especially if you need to use the Windows Phone Recovery Tool to go back to Windows Phone 8.1.
- The Office Hub has been removed from this build. You won’t be able to open Word, Excel, PowerPoint or OneNote files in this build. Preview versions of the universal Office apps will be available in the coming weeks.
- We are redoing how text messages are handled and processed by Cortana so in this build text messages cannot be read out over Bluetooth.
- After upgrade, some apps that have been installed onto a SD memory card will fail to launch. To fix this, uninstall and reinstall the apps.
- About 1% of the time, incoming phone calls may not play a ringing sound.
- Call + SMS filtering will not work after upgrade.
- For people upgrading their phone from Build 9941, there is a bug in which your phone’s MMS settings will be lost after upgrade. The new Messaging app doesn’t yet have the ability to re-enter these settings. You will need to use the Windows Phone Recovery Tool to go back to Windows Phone 8.1 and then upgrade to this build to get MMS working again.
- Also for people upgrading their phone from Build 9941, the tiles on your Start screen for the Camera and Photos apps may be missing or corrupt. You will have to unpin any corrupt tiles and re-pin the apps to your Start screen.
- On some phones, due to a scaling bug the dismiss button won’t be visible when an alarm is triggered. To stop your phone from “alarming “just touch the arrow and swipe up on the notification and off the screen to end the alarm.
- On phones with 512MB of memory, apps can randomly crash due to an issue with memory management.
- Flight mode cannot be enabled.
- Data connections can’t be disabled.
- You may need to re-pin the Phone app after upgrade.
- The Insider Hub is now included on Phone but may fail to launch on some phones.
