I updated my iPhone 6S to iOS 10 and as always I immediately reset all settings and configure it from scratch. However I've noticed that the call volume and the speaker volume is way lower than with iOS 9 - and I have it set up to max volume. I compared it to my father's 6s, which is still on the latest iOS 9, and the difference is quite noticeable. Has anyone else experienced this issue since updating your 6S to iOS 10????
