So, Windows 10 Mobile Build 10581 is here and while the build comes with direct upgrade path from older builds, there are some known issues and precautions you should know beforehand. You can read the official changelog by clicking here.
Build 10581 known issues:
- As with previous builds, after applying this update the device may appear at a black screen for about 5 minutes when transition between the spinning gears and the final stages of update. Just be patient and it should progress past it. Exact time will vary by device.
- You will be unable to set your default save locations via Settings > System > Storage and will not correctly reflect the current storage settings. If you are using a SD card in your phone, it will show up as a garbled name in Storage settings. Whatever you had configured for your save locations in the previous build will be the same.
- After moving some apps to a SD card, those apps might crash. The workaround is to reboot your phone and those apps should work fine thereafter.
- Deploying Silverlight apps through Visual Studio to your phone won’t work in this build. You can deploy UWP apps to your phone without any issues.
- If you restore a backup from a phone that had a different resolution, you may end up with a corrupted Start experience. The workaround is to go to Action Center (which won’t be corrupted) then Settings > Personalization > Start and apply a different background picture.
