How many FPS is the Samsung S23?
*On Galaxy S23 Series, users can record approximately 0.5 second of video captured at 240fps and digitally enhance the video to 960fps with approximately 16 seconds of playback. Playback time can be edited in Super Slow-mo player. *Digital zoom magnification varies by device

Yes, this seems a great camera rate - but the app expansion is also available on my S10+ it has the same frame rate, video recording time and playback speed. It doesnt have the bigger fps rate, but I can shoot for 6-8 seconds and get 14 seconds of playback time.
I think this is all because of the Super Slow motion function it now has.
When I bought the phone new, it didnt have that.
It was put on as an upgrade at some stage - I didnt notice it until I went to shoot the UFO vids.
I can confirm it works though - if thats any consolation.

I'm thinking of upgrading my old Samsung phone to this new phone for the higher frame rate.
I think there is a problem though when (on my old phone) in processing/transferring the higher frame rate - I need to sort that out and see what's going on. It still seems to playback with less frames per second, though the footage is taken the higher frame rate.
Are you thinking of getting this phone Adam?

Maybe on my days off

Seems like it could be alot of fun
