My phone exists mostly for YouTube, WhatsApp, and providing a wifi hotspot for my desktop computers. (It is irritating that much about the phone itself assumes that the mobile broadband is a fallback, and that I have a separate internet connection to give me wifi. I don't. It sometimes refuses to install updates over mobile broadband, and insists that I find a wifi connection from somewhere, by going out to a café or something.)
