Yesterday, Gabriel Aul stepped out from the coding confines of Microsoft to talk about Windows 10 Mobile and the next Insider build. Windows 10 Mobile build 10240 evidently has a severe enough bug to prevent its distribution to Insiders, leaving people on build 10166 instead. The good news is an even newer build is coming, likely in a few days ? so either later this week or early next.
This intro brings me to something I and many others have noticed when using these builds: do a hard reset (aka master reset) for a better Insider experience.
I realize that this is a rather cumbersome task, especially if you have lots of game saves and customizations. However, if you want the best experience it does seem doing a fresh install or hard resetting after an update is your best bet. Wiping away the old and letting the OS do its thing on fresh hardware is a superior experience.
