Sony Xperia C3 photographed next to Xperia T320
Both the T3 and C3 have 720p displays, but the latter is a bit larger, because its screen measures 5.5-inches, while the screen of the T3 is a 5.3-inch one. Other differences: the Xperia C3 comes with a wide-angle 5MP front-facing camera (which allegedly makes it the word’s best selfie phone) that you won’t find on the T3. However, the Xperia T3 also has something that the C3 lacks: a stainless steel chassis.
All in all, the two new Xperias have a lot of common features, including Android KitKat, quad-core Snapdragon 400 processor, 1GB of RAM, and 2,500 mAh batteries. The Xperia C3 is the mint-colored handset below, while the T3 is the purple one. Let us know which one you like best!
