I've been running the latest iOS beta on my iPhone X for the last month -- and so far I'm quite pleased. If you're wondering what to try first -- I'd steer you to the Do Not Disturb feature, as it has been my favorite up to this point. So much so -- I've had it on for literally three weeks. I'm missing notifications and calls left and right, but wow -- it works so much better than the previous version.
You can give it a try too -- so long as you have an Apple Dev account.
You need an active Apple Developer account to get the beta.
