Power management setup doesn't work on some Huawei devices
Some Huawei devices running Android 10 throw a SecurityException when we try to open the App Launch settings (#2270 (closed)).
!1602 (merged) fixed the crash by catching the exception, but we need to update the UI so that it shows instructions for opening the App Launch settings manually.
These instructions will involve several steps and may be hard for users to follow. Unfortunately this means on affected Huawei devices, users are unlikely to succeed in protecting Briar from being killed.
Affected devices:
- Huawei P40 Pro without Google apps
- Huawei P30 Pro
- Huawei Mate 20 X
- Huawei Mate 20
Not affected:
- Huawei Y6P
- Honor 8A
