I would say so, yes in my case. The 12 Pros has 6GB of RAM. For me on my 12PM, that keeps it feeling smooth and I deal with minimal app reloads, significantly less than any iPhone with 4 or less GB of RAM. Feels like it’s futureproofed in a sense since this year is the first time the iPhone has more RAM than that (15 Pros have 8GB)

On iOS 17, newly autocorrected words and sentences are temporarily underlined so that you can easily see the corrections. If you’re unhappy with any correction, you can tap on the underlined word or words to view what you originally wrote, as well as other autocorrect options.

If you haven’t updated, you should. Sounds like it will be the solution to your problem
