the USB connector is a box that is not open to the inside of the phone, at least every one i've seen. I've even seen a couple of phones where the box that held the USB connector also had a speaker in it. I guess a headphone jack could be put inside of a similar box, but the main difference is all the contacts in TRR plugs are spring metal that are attached to the outside of the plastic housing and poke through, and that's if the spec calls for any sort of reinforcement. The simplest headphone jacks are just spring metal in empty space.
I sent this to my gf, but performance is very bad (Intel N4100, hw acceleration turned on), what can be the reason? One would say modern integrated graphic can run animation like this without issues.
I cut alcohol completely 4 years ago. One day I released that it is too harmful for me and to people around. It was not about having fun anymore, it was about drinking, having little please from it and then regretting that. That was a breaking point for me.
