Ps4 : NPC dialog bubble size

I'm a bit desesperate...

Earlier today, I read somewhere that you could change the size of the dialog box with the touchpad and R3 durrings cutscenes... I played around a bit and it worked, except that it put it to the smallest size...
Now, i tried to reproduce what i did and I just cant :( I'm not sure if it a question of timing of pressing the button but now I can't really play unless I read the logs in the chat box...

Can anyone help me ?

ps: I did search and google it but I only get result from around feb 22-23... which nobody know how...

hmm sorry i cannot be of more help as i had the same issue when first switched to PS4 (beta was the same)
I recall using the touch pad and then you have to drag over the hand to the corner of the box to enlarge it i believe.
hopefully someone else can be of more help

It work with the chat but not the dialog with NPC.

From what I read, I am doing it right, but I'm not fast enough. R3 and the touchpad are not the most responsive button, so it might be why I'm having a hard time...

Yeah the touch pad is super sensitive. I will try it out tonight and if find anything will report back my findings
