After pushing Build 14393.594 to PC insiders in Release Preview Ring, Microsoft has now pushed Windows 10 Mobile Build 14393.594 to Mobile Insiders. The Build is now available and can be installed using Phone updates.
Microsoft may be planning to release the first non-insides cumulative update on Patch Tuesday ( January 10). The push of Build 14393.594 may be for the testing and feedback before it or any newer build finally rolls out to non-insiders.
The Build 14393.594 may bring many fixes and improvements to issues faced by users with the last release build 14393.576. The changelog for Build 14393.594 is not known yet, but we will update this article once it is available.
Thanks Matheus Vinicius for the tip. Cheers!!
