Biggest peeve: on the LG phones I had, you could use the volume buttons / menu to silence or turn down individual applications. On the pixel, out of the box you only get a global media volume control.
Also have experience with the stock phone dialler putting up prompts while I am in the middle of doing something else, which never happened on LG. The other big annoyance is the timer portion of the clock app is significantly harder to use.
All that said, I will happily take stock android on the pixel any day over any Samsung product.
On a computer (a real computer), the first words would be something like "On Firefox 106.0.2 64-bit", but phones have such abysmal user control that most of the time we don't even know what programs we're running.
In android, every app version is found in the exact same place on my phone:
Settings > Apps > (select an app) > very bottom has version number. App details takes you to the full details page in the play store, which shows the full name of the app and the publisher name.
Right now, this is my only major gripe on an otherwise great phone.
