OnePlus One Queries?
1. Will it work? Yes. Because although some of the network band frequencies match with some in Australia, OnePlus did not launch the OnePlus One in Australia. According to this YouTube video, he used the Optus network and it worked fine: https://www.youtube.com/watch?v=OdZWn-ys... 2. That's a tough one, depends on what you define as better. The One has more customization options, because it runs CyanogenMod out of the box. So, themes, can be changed right away. The One has the ability to let you choose between capacitive or on screen buttons. Nexus devices will receive updates from Google much faster than the One, only because OnePlus has to modify the updates first before pushing them to the phones. However, the One is updated faster than other phones from Samsung, HTC, LG, etc. The operating system basically looks like the stock android on the Nexus 5 with slight differences here and there. 3. You can buy it online. However, make sure you get the International version. The chinese version only works in China. Try sites like ebay, amazon, etc. to find the phone. 4. Android is already the default OS. Mine is running Android 4.4.4 KitKat.
