Latency when recording screen on iphone 6s

Greetings friends, I see that the phone slows down and I lose quality in the image, presenting latency in it, I have cleaned the ram and cache, what else can I do, thanks

Are you using a screen recorder app? If so, that is most likely the issue. GO4 is very RAM hungry as are most recording apps. There is probably not much more you can do about it other than replace your device with one that has more RAM. Running both apps at the same time will do that.
