While speedrunning Portal, I've always tried the trick where I get the radio from the room near the beginning and put it next to the door at a slanted angle. I would soon figure out that there was a glitch where you could skip that entire section and go to the last part of the chamber. I've tried the trick and failed many times. One time I did it but I haven't been able to replicate it. Since then, I've always had to the trick with the radio. Does anyone know any easier trick?

do u mean the camera or is it actually the radio

Check any speedruns on the site and you'll see the ways there are.

It's the radio

It is easier to do with a camera, it is also faster.

Oh really. I need to use the camera. Thanks!
