I have a phablet (cell phone) that I bought from China which is a knock-off of the Galaxy Note 3. It's a 5.7" screen but I'm curious why it is that utilities such as CPU-Z and two others all report it as a 4.6" screen.
I mean it is not just the size of the phone's screen that makes it good but also the other features such as ram, cpu, rom and camera. A good combination of these specs plus a good looking design will make a great phone. You can also just go for a 5 inch screen since you will get better resolutions.
