Just got a new phone (OnePlus Nord 3), turned refresh rate HUD in developer settings and I see some parts of the system and some apps display 120 Hz but I have problem noticing any difference, same with my wife’s Redmi Note 12, i have to look very carefully and maaaybe I notice some different, not sure
120 is about latency more than anything else. When you play a game in 120 you notice how fast the reaction to your controller presses are making gameplay super smooth. On a phone, I can’t imagine that being as noticeable for day to day use.
