I asked my community which devices they are using and then focused my application over a few makes and models specifications. Just to make sure that when the app was published it would work on the majority of the game's fans gadgets.
Keeping the community up to speed about tested models and those to come left the community less likely to leave negative comments, and I would apologize for the waiting game.
Maybe I was lazy by doing this, but feedback would surprisingly be centered around a specific range of Samsung Smartphones. I would have been wasting time and resources trying to get my app going for models of phones and OS's NOBODY in my close ranged community was using.
More like strategically seizing "Smartphone and OS's" terrain little by little focusing on the most obtainable one first.
But, yeah, that's me.
