Aroo? I thought BlueStacks was the only game in town, and most of my attempts to use it have been extremely frustrating for one reason or another. What other ones did you try, and what made DuOS superior?
I think I tried BlueStacks and Andy, plus one other I'm not recalling the name of, offhand. I don't think I tried GenyMotion (I think that's the right name).
I know some were using VirtualBox, and wanted to force install a specific version. I already have VirtualBox set up with some virtual machines, so don't screw with my setup.
Others, I kept seeing graphical glitches. For example, in FF Dimensions, I could see the seams between tiles due to bad stretching/filtering going on.
It's been a few months since I went through all of this, so I can't remember exactly which was which as far as my issues with them are concerned. I did end up with DuOS, as I found the performance to be decent, haven't noticed the same tiling graphical glitches, and it seems to handle full screen well enough. Coupled with an app to lock the rotation, I can force everything to the orientation I choose. I have run into some issues with a couple apps here and there with certain orientations, but that's likely due (in some part) to my monitor's unusual resolution (21:9 monitor) and the developers setting the screen size based on a more "normal" screen aspect ratio.
Edit: I will note, DuOS is like $10, but you can get a trial version to test with... and it's a lifetime license, so updates are free.
