In the US, the only time you’d have to boil water before drinking in most places is if there’s something wrong with the water system and they put out a “boil water” advisory, and that’s pretty rare. It’s definitely not something you have to on a daily basis. Some people will use water filters but it’s not usually a necessity.
I use Libre Camera. It’s OK. I suspect Google Camera is better but I don’t feel good about installing it.
