Awesome! Thank you so much. I have been looking for this forever.
Using the method you mentioned, I have managed to calculate hex code for 18:9 smartphones (or 18~20:9 phones with a notch)
It's 0x40000000

For anyone who wants to use this, simply replace 0x4017B426 with 0x40000000 from the original post and activate the cheat. Don't load state after activating the cheat, use the in game save point.
