The camera is fine but I prefer to use googles camera app. Both work.

I looked into this a while ago. It seems the best you can do is to try to look the most “average”. All attempts to obfuscate details other than “average” make you stand out even worse.

I used it for a few months. Mostly with snikket. It worked fine for Android but I had problems getting notified on an iphone.

I wear a hoodie most of the time. I don’t mind if you feel suspicious of me; one reason I have a hood up is because I don’t want to engage with random people. Sounds like you would go out of your way to avoid me so mission accomplished.
