If you open the pause menu close the pause menu and then with specific timing open the phone you will be able to walk around and interact with stuff but the phone menu will still be open. this allows you to skip certain cutscene buy exiting the phone menu with ESC at the right time. Below I added some uses I found.

Getting run over but not dying

Skipping pondering over traffic jam

Here check the website: https://www.rail.co.il/ So yeah... I think its good that we agree to not touch that button

I was trying a new glitch in the game that uses the "To the railway website" Button and i spammed that sucker so much the site crashed!

I managed to recrate the glitch!

So in the part of the escalator, in the third escalator if you go between the two sets of stairs in a very specific place you can keep going up the escalator without the animation you just walk normally if you want you can even go back (I could not recrate it yet but I am trying)

Well hello there

I recently found a glitch that seems useless to me but maybe someone else will find it useful. If you pick up the phone at the beginning of the game you can press tab and esc quickly one after the other (I do not have a method) eventually the game will run normally and your character will be able to move freely but the pause menu will be open
