After a lull in rumours regarding the Galaxy S4, GSMArena has revealed some specifications for the upcoming smartphone. The latest rumours include a 4.99in Super AMOLED screen with a full HD 1080p resolution. See Samsung Galaxy S3 review

If this is the case, what we might as well call a 5in display will have a whopping pixel density of 441ppi. It is thought that Samsung will show off the 1080p screen at CES in January. Group test: What's the best smartphone?

The Galaxy S4 will take on Apple's iPhone 5. That is, if we haven't got the iPhone 5S by the time it arrives.

Another rumour suggests that the Galaxy S4 will use an Exynos 5450 processor, a quad-core Cortex-A15 chip. It's supposedly a quad-core version of the Exynos 5250 which powers the Google Nexus 10 tablet made by Samsung.

Lastly, the S4 will supposedly have a 13Mp rear facing camera, a possibility for the Galaxy Note 2 which never came to fruition. "Samsung can't have three consecutive generations of Galaxy S phones using the same camera, can it?"
