I find that I slip into the same habit sometimes – specifically, when I’m typing something where perfect grammar will come off as overly formal, but I’m stressing a bit over what level of informality is appropriate. It taxes the frontal lobes, which means that my thoughts are disjointed in a way that ellipses just make sense with. I think it’s so widespread among older people because when they were first introduced to instant messaging, they weren’t sure how they would come off, and then it became a habit. But that’s just me guessing.

I cannot into computers, but draining the capacitors before rebooting has fixed this issue for me in the past. Not sure if this is even possible on your device given you’re running Plasma Mobile
