Can I suggest joining "the Toastmasters" https://www.toastmasters.org/ . I found it very educational. I learned that was rushing to fill the "dead air" before I had fully formed my thought (read:sentence).
All my "um"s and "er"s disappeared. You will be fine.
Probably 1+ 6t (that's before it was merged). No bloat nice phone.
Or my old BlackBerry before they stopped bothering to test anything and rested on their laurels. I miss the one place portal everything posted its notifications etc. Android is awful for that.
I like my Pixel 7 Pro (current phone) but I have to have a launcher on it because their home screen sucks.
