Schoening yeah i agree i think some of these people(not all) don't realize what going into a native exporter. Look at unity they have 100s of people working on their exporters and they still suffer on alot of devices because android like TiAm said has just become bloated and a lot of manufactures have terrible drivers or have skins that make gaming impossible(looking at you Samsung)
So you have to write things in your exporter just for these devices. Android has a terrible fragmentation issue. Your not even guaranteed OpenGl they all have different versions sometimes they even have a custom version. Making a Native Android exporter would be a massive under taking that even Unity or Unreal cant really get right(they export to a much smaller subset of devices).
