I have zero regerts going to GrapheneOS. Still, I understand wanting to go back to a dumb phone. I miss the old internet.

Anybody notice a stock “Now Playing” app has automatically downloaded on their Android without their knowledge at some point?
Because I definitely want my phone always listening just in case there’s a song I don’t know that can be identified by an app I’m not even aware of!
God I need a dumb phone.

Now playing has been a thing since the pixel 3. I think it works by having an on device set of hashes for the starts of songs and listens for them snippets to then show it on your lock screen for what would be the duration of the song or until it hears another.

Thank you for giving me more background here! I was vaguely aware of this feature but believe I disabled it earlier on (along with other unused features and app permissions en masse) so the surprise app was a shock. I’m tech-aware but not savvy at this point so I just risk mitigate where I can.
I don’t have experience with Shazam or similar for context, so do most apps like this utilize snippet hashes on device? (headed to wiki but thought I’d ask)

I read up about it a while back, so anyone pleas correct me. It works like this I think: An audio sample is recorded, chunked into overlapping windows, which are converted into a spectagram (the black, blue, yellow, red image of frequency vs time). Idk at which point what is send to the server but to me it would make sense to keep the data amount low by sending after the next step: From the spectagram, the algorithm searches for high spots or notable “pixels” in the spectagram. It then notes the relative position between many spots, not only the next but lets say 10 per spot (propably more, as just a pair of 2 numbers are super cheap and small). We then hash these relative vectors. So we now have a list of frequency vs time vectors hashed in unique strings of our recorded audio windows. In the database we have all songs send through the same algorithm and stored. We then just compare our hashes from the recording to the database and find the song with the most matches.
Its pretty smart and I suppose there are additional filters to speed up the process and make it more reliable. Its just so simple, I love it

Shazam is likely a bit more complicated and accurate since you’re sending data to an online service and you actively check a song at any time.

It was a Pixel feature that they turned into a standalone app.

Man, knowing nothing about what you’re talking about and being confidently paranoid is an amazing way to actually miss the ways the corpos are fucking you.
It’s too complicated to even begin to describe why what you’re saying is embarrassingly wrong, and that’s actually ok, not knowing how your phone works is not something against you, being confidently incorrect and not even wanting to learn is.tubthumper@lemmy.world 1 day ago
Thanks, man. Been having a shit week. Literally just noticed this standalone app today. Have actually had problems with paranoia before. Though it should go without saying to anyone that my second paragraph has an obvious /s attached it.
But again, thanks so much for telling me I’m embarrassing and I don’t want to learn anything, even if I posted this on a literal no stupid questions page, with an open ended question, akin to “does anybody else…?”
Yeah, okay. I do want to learn.
I especially want to learn to make sure I never explain anything to anyone like you just did to me.

Isn’t that purely on device?
Candice_the_elephant@lemmy.world 2 days ago
It is. Unless you have you’ve attracted the attention of a state level spy agency, then it’s a useful tool in the arsenal of weaknesses on your device.

I don’t think they need you to have the now playing thing working to do that
