I and others have commented have had problems playing music in the car through USB. Any possible fixes in 12.1.1?
 
Release Note added to wiki

Remaining Issues to test on this build
  • Lock screen orientation glitch in the Control Center: If you have screen orientation lock enabled, and then change the state of "Increase Contrast" in Settings, for example enable it, your lock orientation icon will be fully white instead of red.
  • Some apps like Google Maps and Clash Royale will lag on iPhone X and above: Open the affected app, for example Google Maps. Do not do anything else, just minimize your brightness to the lowest. Now, you will see the app's FPS number has been drastically decreased, try to do circles in the map, you will see it is laggy. To make it smooth again, you can: A) Start screen recording or B) Increase brightness.
  • Folder in Dock bug - swipe to widgets and then back to home screen: it will blink.
  • Grouped notifications glitch - Expand, collapse and then expand again a grouped notification quickly, it will have a glitchy animation.
  • Text in the home bar in apps such as WhatsApp, FB Messenger and MyFitness Pal will glitch when swiping between screens causing the text to become closer together
  • On an iPhone X, XS, and XS Max, if your home screen have multiple pages, go to a different page other than main, then swipe up to get to your main page. After you quickly want to open anything in the Dock, you can't, you need to wait a few seconds to be able to do it.
  • Lock screen time & lock status glitch: using your locked iPhone, swipe from right to left two times quickly. For the second swipe, your time and lock status will disappear.
  • Notification center missing background: Lock and unlock your phone. Then open an app, and quickly pull down the notification center. It won't have background for a few seconds.
  • Landscape mode control center bug: Open anything in landscape mode, for example a YouTube video in full screen. Open your Control Center, swipe from right to left, then close CC. There will be a stuck bar at the top of your screen for a few seconds.
  • App crash bug: Open the app switcher. Tap on an app, swipe it up to close, but while its closing tap on it - > glitchy crash.
  • Adding the first widget in the available widgets list will have a glitchy animation.
  • Safari: "add to home screen" - when there is just one home screen, it does not show the recently added icon. It does create a 2nd home screen page but when you swipe left the icon is missing. After a reboot or waiting for several minutes, the icon may appear.
  • Since iOS 11.4 still can’t initiate ‘album’ playback via Siri on the watch with music that is locally stored on phone.
  • When iCloud Keychain and text replacements are enabled, text replacement won’t be offered anymore when trying to login. The specific text replacement is overwritten with “Password”.
  • Some Text Replacement may not work

I don’t see the option to turn off the physical sim on the XS. Under the eSim I have the option.

I thought 12.1.1 allowed you to turn off the physical sim?
It is definitely there for me, I can turn either line off now.

The carrier settings have been updated for me, I wonder if is dependent of that?
 
Im also gonna stay on public unless anything major is changed, always tempting tho

Any performance improvements? I've had the TMo XS and I've had problems with upload speeds, wondering if this will finally fix the issue.

Too early to say - am still at the office, and my speed / signal here is terrible in general. Seems about the same right now, but I can't fault that on the XS Max.

I should mention, my issue has been download speeds as compared to my wife's iphone X Qualcomm. This only seems to happen in low-signal areas as well. We tend to get the same number of bars, but my download speeds in these locations would be half hers. I'll try go back to a known trouble-spot to test on my way back home. At this particular location, resetting network settings would momentarily lead to matching performance with her X before dropping back down a few minutes later.
 
Swipe to unlock now moved to top of the screen after failed unlock face id attempt.
