When new combinations toggle is turned off, the home+power button doesn't work for taking a screenshot.
When the toggle to show the homebar is enabled, the homebar doesn't have an inset so it overlaps the tabs.
The flash and camera quick toggles on the lock screen doesn't works (seems to be only an issue on iOS 12.0 to 12.1).
When using the Modern (Large) status bar in apps other than Apple's stock one the status bar is the default one instead of the iPad one.
The phone overheats for some reasons and it's causing battery drain.
When using the iPhone X like keyboard, the globe and the microphone doesn't have the same spacing as the stock iPhone X spacing.
Suggestions :
Make the rounded corners optional.
Make an option to completely disable the homebar and not the fading thing.
Add the FaceID padlock glyph on the lockscreen, the padlock would unlock when the phone has been unlocked with Touch ID. This tweak does that but it's broken on iOS 12.
Add an option to disable the gesture to switch between apps when the keyboard is present.
Add an edge protection when the keyboard is present.
