This is allegedly the dual-SIM version of one the Samsung Galaxy Mega 6.3 DUOS. It is a huge phone. The DUOS variant is pretty much identical to the single-SIM Mega 6.3, aside from the ability to have two SIM cards in it. Everything else looks the same.
The handset is going to come equipped with a 6.3″, 720p LCD display, 1.7 GHz dual-core Exynos processor, 1 GB of RAM, 8MP camera (2MP front), microSD card slot and Android 4.2.2 Jelly Bean. This could replace your tablet.
We don’t have an availability date yet, but it should arrive soon if you are looking for a huge phone.
