Android Auto notifies of speed traps in the USA, but not cameras as far as I know. However, AA is the best map program I ever used. The voice activation is easy to use and directs at a 98% efficiency rate.
Don't know if they are legal in the UK, but my Escort 360 includes every kind of radar, laser, speed traps, camera alerts, you name it. There is one thing radar detectors always need to keep in mind. If you are shot with instant-on radar, just take out your license, registration and insurance and sign the ticket. Even Escort admits that under professional use of instant on, by the time the detector detects, it's too late. Hope this helps.
