A Windows 10 Mobile Insider build (10536) that was mishandled by Microsoft has made some phones useless. According to the firm the build was only intended for certain phones but was mistakenly made available to other handsets.
Microsoft is working on a fix for those Windows Phone owners with a dead device.
Microsoft has acknowledged enthusiast frustration over a lack of high-end flagship phones, and has stated it is focusing on them. Chris Capposela, CMO for Microsoft, stated at a conference in NY that the company has "massively retrenched" around Windows 10 for phones.
Capposela went on to say that Micrsoft wants to build a premium flagship phone for Windows fans.
