Windows 10 build 14393 now available for Insiders on PC and phone

Microsoft is pushing build 14393 for Windows Insiders for PC and phone today, featuring a whole batch of new bug fixes for you to enjoy. I've heard whispers, alongside other reports that claim this build is the one that'll roll out to the public on August 2nd.

From today's announcement:

Improvements for PC

• We have improved the reliability of Start, Cortana, and Action Center.
• You should now be able to mount iPods as USB mass-storage devices.

Improvements for Mobile

• We fixed an issue resulting in rapid battery drain when Visual Voicemail syncs voicemail messages on Dual SIM devices like the Lumia 950 XL.
• We also fixed an issue causing some battery drain on older devices like the Lumia 535, 640, 735, 830, 930 and Icon.
• We fixed the issue causing Voice Recorder to not show up consistently as an option for Call Recording. A app update was released last Friday that fixes this issue. Make sure you have the app version 10.1607.1931.0.
• We fixed several issues impacting Dual SIM capabilities. Using a device with two SIMs should work as it should.

Known issues for PC

• We are aware of certain cases in which Surface Books and Surface Pro 4's may bugcheck (bluescreen) due to a camera driver issue. An updated driver will roll-out via Windows Update soon that will fix this.

Known issues for Mobile

• We are continuing to investigate W-Fi issues on certain devices.
• Turning off Bluetooth can sometimes result in freeze, crash, or reset. See this forum post for more details.
• Wallet users are prompted for a PIN twice when using tap to pay from a locked phone. You can enter their PIN twice and tap as usual once the phone is unlocked. A fix for this will come as a Wallet app update via the Store.
• REMINDER: We have changed the backup format for Windows 10 Mobile devices to reduce the size of the backup stored in OneDrive. As a result, if you do a backup on a device running the latest Windows 10 Mobile Insider Preview builds and move back to the released version of Windows 10 Mobile (Build 10586) and restore from your backup – your Start screen layout won't restore and remain the default Start layout. Your previous backup also gets overwritten. If you need to go back to Build 10586 temporarily, once you are on Build 10586 you should disable backup so it doesn't overwrite the good backup from Windows 10 Mobile Insider Preview builds. We will stop noting this going forward.

We're just 2 very short weeks away from the official launch date for the Anniversary Update, so it makes sense for Insiders to start testing the final bits now. Over the next couple of weeks, Microsoft will be flighting a number of hotfixes and patches to build 14393, all in preparation for a day-one patch that the public will download on August 2nd.
