The iPhone 18 Pro has been out exactly a month now and they still haven't pushed a fix for the popping/crackling speaker issue:

I still get crackling or popping many times a day.
Also, the annoying render stutters during scrolling across many apps haven't been fixed since iOS 26 was introduced (they were probably there before, but Liquid Glass made it worse). Even the iPhone 18 Pro suffers from it (also checked on iPhone 17 Pro and iPhone Air).
Meanwhile, my underpowered P10P with GrapheneOS renders scrolling super smoothly.
