Everytime i film videos on my front camera it lags and if i move a little it's not smooth at all and looks like i've been filming through 10yo phone... Especially it gets bad if i film when its darker or through snapchat.... I've had s20 before this, and never had a problem, but now with newer model i can't film videos? Is there any way to fix this?
Have you checked the FPS and quality you are shooting at? It is possible the video is "stuttering" because you are shooting at a lower framerate and resolution.
As for low light situations, the way Samsung tries to brighten images/videos through processing can introduce some grain and motion blur.
Snapchat is a known issue, on Snapchat's end. Instead of using the native camera app, Snapchat chooses to screenshot the viewfinder, for whatever reason, resulting in low quality on Android devices.
