First concert abroad - etiquette question

I’m from the US and this will be my first show in the UK. I’ve been to many concerts at home and usually try to not be the guy ruining someone else’s time. (Ex: Standing the whole time while the rest of the section is seated, holding my phone in the air taking video the whole time, excessively screaming, etc.)

Any UK-centric concert etiquette I should know about that I might not have considered?

Can’t wait for this!
