As you said, the Android phones were developed by Nokia before the acquisition was made. They were initially released by Nokia just before the acquisition went through. Also, I suspect you mean Windows Phone - Windows Mobile stopped being a thing in 2010, if I'm not mistaken.
I have a Nokia X1 and it's what you'd expect from a budget phone - low spec so a fair amount of lag. No Google Play but then the phone is aimed squarely at emerging markets (although there's a way to enable Play on the X1 anyway). The part I like most is that it's dual-SIM.
