I just had to uninstall/disable Google+ app to get rid of the annoying "Google Photos" app. I think the "auto awesome" is feature is f****** stupid. I just spent an hour crawling through my /system/app directory looking for the package to delete as root, after I found out that it wasn't easily disabled/uninstalled like any regular app.
I can't wait until Ubuntu mobile is more stable. When it is, I am ditching Android. I'm tired of how companies like Google, Amazon, Facebook, etc., all want to snoop on every bit of your private photos, emails, text messages, etc. They all want to be your "one and only" application, and that's unrealistic.
Sorry, I'm a bit annoyed right now. I don't mind Google+ as a social platform, but I do think it was stupid of them to force their stupid photo **** onto the whole world by making it a mandatory part of Google+ mobile app. Screw that...I will just use the mobile site if necessary.
