I’ve been using Google Pixels since they were Nexus phones and just activated my new 14 yesterday. It’s a little weird but I like it so far. I do miss twire instead of twitch, YouTube re-Vance’d, and Firefox with Adblock. What does a long term android user like me need to know/install/settings tweak/etc?
One piece of advise I can give; do not try to replicate your android experience on iOS. More than likely it will leave you frustrated. Make the switch with an open mind to a new way of doing things and you will have a much better time.
