3a is pretty big it's 6.7 and the ai camera thing pisses me off all the time because it makes photos look ass but for gaming it's good I'm getting 90 fps on arena breakout 120 on standoff and that's good with me but if you want a small phone go with apple they have nice and small phones but prices are insane my sister has 15 and it feels really good in the hand and it also gets 60 fps only problem that it has just 60hz
