The RAM management isn’t perfect but it does a pretty decent job.These are the biggest issues I see. I have in the past had a dev recommend to reduce apps in the app manager to see if it helps (usually did)
Apple seems to have frequent issues with being to aggressive or too passive on RAM management.
- App locks when trying to open a movie, photo, or document.
- App launches but reacts sluggishly.
- App won't launch at all or locks in load process.
I do find I am doing a lot less than say a couple OS generations back.
All the issues you mentioned should go away with closing just the one app 99% of the time and a rare occurrence in and of itself. But it is a software and being as sophisticated as it is these days issues are inevitable. Closing an app or hard reset should take care of it as others have mentioned.
