Don't simply judge a phone performance by just a game. I totally understand your feeling, however, from what you mentioned, I could see it's only happened to the specific games (王者榮耀). You may complaint about the "low latency" as you wish, but before that, do provide some recording to identify where the real problem and not just simple write few words then want people to hear from you (or do something to you)
Another one thing, shout and complaint about the phone's problem like what you are doing only if you have experienced the same problems (touch sensors problem) to games, UI and etc (show with the video recording as evidence) . Otherwise, do mind about how you ask for help when you need some assistance from others.
