I know its getting old to ask, but i cannot understand why you support crapy devices such as lumia 635 and below , maybe it is more correct to state crapier than ATIV S, and you do not support ATIV S with far more superior camera and specs for specific app
but also for a majority of new microsoft apps.
I don't understand, have I not payed to purchase this windows phone device?
I am not obligate to spend another penny to buy a new lumia phone, but you are obligate to support every device if specifications are up to the level for each app.
