LiveActivity using colorScheme to adapt to dark mode in iOS 26 system does not work

The system keeps returning colorSchema = .dark, unable to switch

What API are you using that is having this issue? Can you please share a code snippet showing how are you trying to switch please.

Yes，I have same problem. Any one fix the problem?

Here is my sample code: struct BroadcastLiveActivityGradientLayerView: View { @Environment(.colorScheme) var colorScheme

private var localImageName: String {
    colorScheme == .light ? "icon_LiveActivity_broadcast_grid_light" : "icon_LiveActivity_broadcast_grid_dark"
}

private var baseBackgroundColor: Color {
    colorScheme == .dark ? .black : .white
}

var body: some View {
    ZStack(alignment: .topTrailing) {
        baseBackgroundColor

        let colors = LiveActivityColor.broadcastBackgroundColors(colorScheme)
        LinearGradient(
            stops: [
                .init(color: colors.last ?? .clear, location: 0.0),
                .init(color: colors.first ?? .clear, location: 1.0)
            ],
            startPoint: UnitPoint(x: 0.81, y: 1.29),
            endPoint: UnitPoint(x: 1.29, y: 0.17)
        )

        Image(localImageName)
            .resizable()
            .aspectRatio(contentMode: .fill)
            .frame(width: 179, height: 149)
    }
}

}

Based on my testing, @Environment(\.colorScheme) starting from iOS 26 behaves differently for Live Activities:

Inside the Dynamic Island, it always returns .dark.

For the banner / Lock Screen section, the value appears to be determined by the current wallpaper/background context rather than the system Light/Dark Mode setting. For example, a light-colored wallpaper should result in .light.
