Rumours of the Samsung Galaxy F are refusing to die down, so as unlikely as a second Samsung flagship this year seemed (or a third if you count the Galaxy Note 4), it looks like it's happening.

The latest rumours are a little different though, as while it was largely expected to have a Galaxy S5-matching 5.1-inch display or above, the Korea Herald is reporting that it will have just a 4.7-inch Super AMOLED screen.

By Samsung's standards that's pretty small, especially for a flagship and we'd heard previous rumours of a QHD display, which seems unlikely at that size point. But it makes some sense, as that's exactly the same size as one of Apple's iPhone 6 models is rumoured to be and with reports claiming that the Galaxy F will arrive in August it could turn up just in time to sway buyers from Apple's alternative.

Small and slim

That would then leave the Galaxy Note 4 to tackle the rumoured larger 5.5-inch iPhone 6. So it makes some sense. That's not all the Korea Herald had to say though. Apparently the Samsung Galaxy F will also be metal clad, as expected, and come in at a super-slim 6mm thick, which would make it substantially thinner than the 8.1mm Samsung Galaxy S5.

It's also said to come with an Exynos 5 Octa processor and will reportedly be called the Samsung Galaxy S5 Alpha or the Samsung Galaxy S5 F when it launches, although the Korea Herald claims that it's internally referred to as the 'card-phone' due to its slenderness, according to industry sources.

We'd take all this with a pinch of salt though. 6mm is awfully slim and this is the first time there's been any mention that it might have a 4.7 inch display.
