Nokia Lumia 635 specs

My issues don't lie with this budget phone per se as with decisions by Microsoft. Microsoft eliminated an app called Lumia Storage Check that provided the function to store maps for offline use on to the SD card. With no reasonable explanation the company built a brand new Here app for Android phones with the added function of supposed storage on SD. The reviewer below oddly reviewed the 635 harshly after it was already being cleared from store shelves to make way for its successor, the 640. I offered a more balanced review as I was waiting for a decent budget phone and purchased it upon it's immediate release in the U.S. and I was not displeased with the phone--it served it's function. I was happy with it.
