Sony Xperia Pro-I is an absolutely monster smartphone as it houses the industry-leading 1" smartphone camera sensor in a smartphone. Not only that, the Xperia Pro-I is also the first smartphone in the world that can record 4K videos at 120fps and be able to preserve all 120 frames. Sony plans to sell the handset for the eye-watering price of $1,800 which is ridiculously high for what it offers and that's the reason, this smartphone is strictly for professionals in my opinion.
