It's not optimized for mobile. 
weak or not, it serves the purpose to test unity games if a project is not optimized the experience is the same with a mid-range cell phone you get a performance of 20 fps or 30 is not ideal one wants a fluid game around a good fps I calculate that 60 - 100 is optimal
Yes,this was an experimental thingy and I hope new android build for a rework will operate much better
