Don't Install Because There's Not Much There
If you're looking to try new features, avoid the iOS 12.4 beta for now.
Most iOS x.x betas bring new features to try ahead of the official release date. That makes iOS 12.4 is an anomaly.
The first two iOS 12.4 betas don't have any new features. Instead, it looks like the update will be used to launch Apple's new credit card later this year.
Apple employees are reportedly using the beta to test the new Apple Card ahead of its launch this summer.
The company might bake some usable features into upcoming iOS 12.4 betas, but as of right now, there's nothing there.
