Today, XperiaBlog reportedly confirmed some of the features of the upcoming handset, also noting that this is the same device previously rumored to be codenamed Xperia Sirius. According to the blog, it’s been confirmed that the D6503 / Sirius features: a 5.2-inch display with 1080 x 1920 pixels, a 2.3GHz quad-core Snapdragon 800 MSM-8974-AB processor (which may also be included in HTC’s rumored One+ / M8), Adreno 330 GPU, 3GB of RAM, a 20.7MP rear camera, and a 2.1MP camera on the front.
We still don’t know if the D6503 / Sirius will be called Xperia Z2. Sony might announce the new handset at MWC next month, possibly alongside the 5-inch Xperia Canopus.
Some screenshots allegedly presenting the UI of the D6503 were posted by XperiaBlog, as well as in a thread at the XDA Developers forum. It’s said that the screenshots date from November 2013 - that’s why they show Android 4.3 Jelly Bean running on the device. But the handset should run Android 4.4.2 KitKat at launch, so the UI will be different. You can see the screenshots below.
