2013 has been the year of the full HD smartphone, where the latest devices blur the line between phones and tablets. There's been plenty of flagship releases already, but there's still more to come.
The biggest buzz right now seems to be around the Sony Xperia Z Ultra. The company claims the 6.4in smartphone is the world's slimmest with a full HD display.
Not to be outdone, Huawei claims its new Ascend P6 is the "world's slimmest smartphone". It also has an "industry leading" 5-megapixel front-facing camera.
Finally, large smartphones seem to be as popular as ever and ASUS has just jumped into the game with the Fonepad Note FHD 6. It's a 6in Android smartphone that comes with a stylus and it's likely to compete directly with Samsung's Galaxy Note II.
