I got the Moly X1 today, thought I'd post some pics comparing it to my wifes 640XL. I did no performance comparision as it is running WM10 version .29 and my wife has 8.1. When the 640 XL is updated I'll run some tests. Notice there is no glance on the X1.
What carrier are you one? Also cand check if the moly has the field test app by going into the dialer and typing in ##3282# then go to Settings. Select Manual for Network type then check Supported LTE bands. Does it support LTE Band 12? I'm wondering you can enable more LTE bands.
I am on StraightTalk (AT&T) here are the bands.
All the band of this mobile phone is 2G:Quad Band 3G: B1(2100) / B2(1900) / B5(850) 4G: B2(1900) / B4(1700) / B5(850) / B17(700) (US).
Update! Both my my wife's 640XL and my Molly are running the same os. Not a difference between speeds. So, 640XL has bigger screen and Glance while Molly has better screen and more RAM. IMO the 640XL has a better camera too.
