They do, and they’ve shared the counter measure (lockdown mode) with the world.
If a nation state will individually target someone, they don’t need to doom scroll on insta (nor do they need to). Locking down the phone to the bare minimum for these kind of people is the appropriate level of response.
I don’t know Android. Sorry. Doesn’t locking down to very very limited hardened features goes against everything Android is (highly flexible customizable for power users who’d want to do that kind of stuff)?
If the feature can be turned on and off by the user then I don't think it goes against anything right, they'd still have the power?🤔 but locking down everything doesnt seem like a great fix for the average user. Bug fixes should be the real fix
As much as I want to believe this is effective, all it looks to do is turn your phone into... a phone.
If they can get cell records, they can track you.
SMS isn't end-to-end encrypted, once it leaves your phone to the network it's fair game. Given that Russia controls Russian Telecom, you can be fairly certain that a phone call and an SMS are monitored.
At that point, you're left with the old school one-time pad. And I can bet on Russia being Russia, so if they see a one-time pad in use, they're just going to pick you up and beat you to death until you talk.
I've had Lockdown mode on since it's been released. I miss having 2FA code autofilled from text messages, and there's the occasional website that'll need to be whitelisted as it may display an emoji instead of a custom font... but aside from that, it's barely an inconvenience.
Your telco is always going to be a weak point in a scenario like this, but better that than your phone because a hostile actor sent you a text message that embedded silent persistent spyware.
