To add onto the phone section: (1) Disable any biometric authentication, and (2) turn/keep it off whenever there’s a chance that it will be siezed.

1. While the first amendment protects you from being required to give up your phone’s pass code, there’s no protection against someone just holding the phone up to your face or fingerprints to unlock it.

2. While your phone is never totally impenetrable, it is significantly harder to access in its BFU state (before first unlock). Most commercially available cracking tools will only work if the phone is in it’s AFU state (after first unlock).

Anecdotally, I’m running Kubuntu on a Dell 7280 with a 4 cell battery as my personal computer, which gets an hour or two of websurfing and home network experimentation per day, and I’m having to charge up once or twice a week. I dunno how that stacks up to other devices or distros, but I really barely think about my battery.

I actually really don’t like this feature, but I just went and checked on my S21, as well as my work S20, and both of them have a Flash notification option, which flashes the camera LED when a notification goes off. Is that what you’re talking about?
