When installing Briar on the Huawei P8 Lite 2017 (Android 7.0/EMUI 5.0.1), the "Protect Briar" button in the setup wizard opens a screen with power management controls that seem to be the opposite of those on older devices like the Ascend Y330 (Android 4.2.2/EmotionUI 2.0).

Users might think they need to change the setting for Briar, which would have the opposite of the intended effect.
