Samsung Galaxy S5 'Prime' Edition Rumours Point To Quad HD Pro Phone

The Samsung Galaxy S5 will be released next week - and it's almost certainly going to sell millions upon millions, attracting users with a best-ever screen, fingerprint sensor and heart-rate monitor.

But if the rumours are true, Samsung might have something even better in the works.

Persistent rumours about a supposed 'Galaxy S5' prime have swirled around the company for weeks, with many speculating it could feature a spectacular Quad HD screen and impressive processor upgrades.

Samsung has always denied the story, and has made no outward signs that such a phone is forthcoming.

But a leaked GFXBench benchmark test for a yet-to-be-announced SM-G906S smartphone from Samsung might have just revealed it anyway. The test suggests the device has a quad HD display, and is presumably in a late stage of testing.

Take a look at the video above to find out more.
