Known issues for Mobile
- If your phone has additional speech packs installed – this build will fail to install on your phone with an 0x80188319 error. This is why we polled Insiders about language pack usage this week. Based on the response, we decided to push forward and send the latest bits. This issue will be fixed in the next build we release. NOTE: Removing speech packs will not correct the issue. Your device will continue to try and download and install the update and fail. It is recommended you move to the Slow ring until this issue is fixed.
