Today I suddenly noticed my 1st gen nest hub screen shows somewhat likea burn screen 90% of it is darkened and have what appears to be several and very thin black vertical lines in the darkened space, I got the device on 2020 so is not that old and have not suffered any drop or other kind of impact. Already factory reset it and problem stays the same.
