Samsung has been reportedly testing two variants of the upcoming Note, rumoured to be called the Galaxy Note 6. Apart from the flat screen, a curved screen variant is also in contention, which is expected to sport a 5.8in screen with qHD resolution at 1440x2560 pixels.

Even in terms of hardware, both the models share most of the features in common, which includes the use of Samsung's Exynos processor. The Exynos-bound model is meant for the European market.

According to sources quoted by GSM Helpdesk, the prototype of the Note 6 being tested apparently use Snapdragon 823 and Exynos 8890 chipsets. Other key features are 6GB RAM and internal storage of 32GB, with support for micro SD card for additional storage.

The Note would come on board with Google's latest Android N. The source further adds that the phone will pack a battery comparatively bigger than any other Galaxy device at 4,000mAh.

It would not be impossible to include the 4000mAh battery, provided Samsung manages to make the Note 6 slightly thicker than the current Note 5. A similar strategy helped Samsung pack bigger batteries in its Galaxy S7 and S7 Edge, according to Sammobile. Samsung would launch only a single variant of the Note 6 as the successor to the Note 5 and S6 Edge+, but it is still not clear whether the flat or curved screen variant would see a market release.
