iOS 15.4 beta adds support for 120Hz refresh rate in all apps

Apple's latest iPhone 13 Pro and Pro Max flaunt 120Hz ProMotion displays, but only a handful of apps support 120 frames per second. Mostly system apps at that. Well, with the upcoming iOS 15.4 software, Apple is finally adding support for all apps to make use of the buttery-smooth experience. It's worth noting that the iOS 15.4 is currently in beta.

For now, iOS 15.4 is still in beta and the information comes from a developer saying that he got the news from "someone at Apple". He posted a screenshot as proof.

Yay, got a little message from someone at Apple today that this is fixed in the iOS 15.4 betas and all apps automatically get 120 Hz animations on supported iPhones going forward, and just confirmed myself. (See attached, 1/120 = 8.33 ms) 🥳🥳🥳 https://t.co/EtZ9zkrM6S pic.twitter.com/04cl8uLb11

It looks like Apple was able to squash the Core Animation bug that wouldn't allow animations to go beyond 60 fps. However, we can't confirm whether all apps will run at 120 fps automatically or some developers would need to tinker with the code of their apps as well.
