adb uninstall com.android.systemui.SwiftDark.Livid.SamsungS8AOSP
Like clockwork, about a month later the BTU phone gets it after the XEU and carrier branded ones do.
Edit*
Pro tip for anyone who is using Substratum themes. You WILL cause SystemUI to force close at boot after installing a system update unless you uninstall any overlays for SystemUI first!
I had to fire up ADB with the phjone on the "SystemUI has stopped" dialogue and uninstall the SystemUI overlay:
Code:adb uninstall com.android.systemui.SwiftDark.Livid.SamsungS8AOSP
It takes a while, but ends up with a Success, and the phone will go to the lockscreen. On XDA some went a whole nine yards and ended up factory resetting their phones in recovery in the past, which is a bit extreme....
No need at all, as long as you've got ADB.
Ah might need to click the popup on the phone to allow permission the first time, but that particular adb command might not need it. Worth trying.
That sucks.
I comple6ely forgot about uninstalling the Substartum SystemUI overlay and just mashed restart when prompted by the update.
You might have an alternative way before you reset though. You can enter recovery mode which gives you ADB access. I've not used it this way before, but you might have the ability to uninstall packages this way too.
My s8 seems to have a weird bug. I can be on the phone in a call and If someone tries to call me while I'm on the phone it rings in the background and it gives me the option to accept or decline as if I've got two phone lines.
Very weird. Anyone else experienced this
