The app removed the ability to hit the equals button repeatedly to perform additional calculations.As of iOS 18.3 beta 2, Apple has restored this behavior to the Calculator app so that repeating operations can be completed like they were before.Beta 2 also provides various bug fixes and performance refinements, but is otherwise light on new features.How to install the public betaExisting public beta users can find todays beta 2 update by opening Settings Software Update on your iPhone.If you arent yet running the public beta, youll first need to join Apples free Beta Software Program to enroll your device. Then the software update will appear in the Settings app for you.Overall, iOS 18.3 has so far proven to be a very minor update.
