I think one thing I would mention, though, my experiences are throughout times from 201X to today, and I attempted playing on my android phones very lightly, though for a REASON:
Android seems to be really, really poor system for gaming. While iOS even early on, was really good. Android seems to have extremely variable input lag (Touch screen) and Sound vs. Video latency differences all around, and this is different from phone to phone, so have fun figuring out where your particular phone stands.
I wanted to use controllers with my android phones and every phone I had, one being nVidia Shield Tablet, made for gaming, but all of them handled bluetooth controllers horribly. Extreme latency at best, outright constant dropouts, stuck inputs and other unbelievably unplayable results. This has been a constant with DualShock 4's, 3's, and several phones from OnePlus, Samsung, Nokia (Now HMD in phone market) and so on. The best controller I have for android is 8bitdo's earlier pad that works the best; but still has significant input lag compared to anything else like a Switch, a Vita, etc.
From here, touchscreen latency is always better on android as I tested but touchscreen controls have not had anything revolutionary to make them feel good, they almost always suck for general gaming. While the default is to not play anything on my phone just about 30 days in a month, if I played something on my phone my favorite games were Professor Layton HD edition(s), Super Mario Run, and Sudoku. Phones are a real fun platform to play electric sudoku with, though DS Kawashima one is excellence without many assists baked in and enabled by default.
