Microsoft rolled out the first Windows 10 Mobile Redstone build a couple of days ago for new Lumia phones, including 950, 950 XL, and 550, but it appears that this last model is actually hit by a critical bug after the update.
Lumia 550 running Windows 10 Mobile build 14267 might not be able to charge anymore and in a statement released today, Microsoft confirmed that it’s indeed aware of a bug that’s particularly affecting this model.
Company engineers said that Lumia 550 owners whose devices are impacted by the bug should return to Windows 10 Mobile 10586.107 because for the moment, there’s no workaround available.
“Several Windows Insiders with a Lumia 550 have reported an issue where their phone no longer charges or connects via USB after upgrading to Build 14267. If you have a Lumia 550, we recommend holding off going to this build. If you have hit this issue we recommend rolling back to Build 10586 using the Windows Device Recovery Tool,” the Windows development team said.
