The Lumia 925 has a high definition touch panel display, a slender alloy body and the latest version of Windows Phone 8 onboard.

It follows in the footsteps of the Lumia 920, by sporting a dual core processor and 1GB of RAM, which is more than enough to make Microsoft's mobile operating system feel fast and fluid.

The Lumia range has become Nokia's flagship family of smartphones in recent years and is spearheading a resurgence for the once dominant Finnish mobile manufacturer.

It is widely held that Nokia makes the best Windows Phone devices and the Lumia 925 certainly does not detract from this reputation.

What makes this phone particularly appealing, is its highly responsive touch panel display, which works well with the already fluid Windows Phone interface.

Although this software offers something quite different from Android and iOS, it is still intuitive enough to appeal to first time users and is gradually growing its market share, both in the UK and internationally.

It was initially rumoured that Samsung would be upping the diagonal size to 6.3 inches, although this was subsequently contested, as other sources reported that a 5.9 inch screen is more likely.

Now, however, yet another potential screen measurement has been thrown into the mix, courtesy of a leaked image published on a Chinese website and reported by TechRadar.

This latest rumour suggests that the Galaxy Note 3 will in fact have a 5.99 inch display, making it as close to 6 inches as makes no difference.

Other information provided by sources apparently close to Samsung, claims that the Galaxy Note 3 will have an eight core processor, 3GB of RAM and the very latest version of Android onboard.

The exact size of the Galaxy Note 3's touch panel is not as important as the one fact that does seem to stick, which is that Samsung is going to make this device bigger than any of its predecessors, by quite a significant screen margin.

While the Galaxy Note 3 will still use the OLED technology found on previous iterations, it is reported by the OLED Association that this time around, it will feature a flexible, plastic frontage rather than a rigid glass covering.

As well as making the phone's display far more durable, since it can absorb impacts without shattering, it will reduce the weight and thickness of the Galaxy Note 3.

This is good news for fans of super thin smartphone designs, although there are some insiders who offer conflicting opinions about whether or not Samsung is actually going to be able to produce its first flexible smartphone this year.

Sources believe that Samsung has actually encountered problems with the manufacture of the flexible displays, with current processes related to sealing the screens taking too long to complete.

If it has to go back to the drawing board, then it might be impractical to include a flexible screen in the Galaxy Note 3, ahead of its predicted September launch.

The Galaxy Tab first emerged as a rival to the iPad, although it has failed to find the same traction in the market as Apple's device.

This has not stopped Samsung from progressing the range each year and these new models sound suitably well equipped.

The 8.0 inch iteration will sport a resolution of 1280x800 and come with a relatively modest 1.5GHz dual core processor. Samsung has allegedly managed to make it thinner than the iPad Mini and only a little heavier.

The 10.1 inch Galaxy Tab 3 will follow in the footsteps of its smaller sibling in terms of screen resolution and processor, while actually having less RAM, for some reason.

Hopefully, Samsung has realised that to take on the iPad, it needs to make its tablets a more affordable proposition. There are of course other touch panel Samsung tablets on offer, such as the eight inch version of the Galaxy Note, so the company will, effectively, be competing against itself.

But a new range, known as the Galaxy Mega, is being developed which, according to TechRadar, could eclipse even the Galaxy Note 2 in terms of sheer screen area.

The Galaxy Mega will be offered with either a 5.8 inch or a 6.3 inch touch panel display, which will come close to matching full tablets for screen real estate.

The 5.8 inch model is actually going to be a mid-range offering, with leaks suggesting that it will have a single core 1.4GHz processor and a display with a sub-720p resolution. With fewer pixels than the Galaxy Note 2 stretched across a larger area, the screen might not be quite as impressive.

Those who would prefer the larger 6.3 inch Galaxy Mega will find it equipped with a dual core processor, eight megapixel camera and Android Jelly Bean.

Samsung seems convinced that consumers want bigger and bigger touch panel displays, but the Galaxy Mega range might be one step too far in the wrong direction.
