When playing a game on my phone and someone calls. Phone doesnt ring.

This is a solution i know of from a previous model if you are launching your games via Game Launcher try swiping from the bottom of the screen to the top while you're in a game > Tap the Game Booster icon in the bottom left > Priority Mode, and toggle this option off. But it will be the priority options of the games/launcher stopping the call notifications that I do know Hope this helps
