I have been reviewing dual sim jellybean phones since the start of the year but only in the past month has it become quite exciting seeing new models from various makers release with better and better features and at an ever increasing affordability.
first their was the Galaxy Grand with one of the first dualsim 5inch jellybean widely available in the market but shortly after i gave the Lenovo P770 the crown as the best all around as it changed the game with extra long battery life and mobile charging (also works with usb mouse and keyboard

dualmic dualcam dualsim dualcore.
then Cherry came out with another game charger the Omega HD with superb camera and display with aesthetics to match that the P770 can only drool over however it had three things that fell short of winning a permanent place in my pocket. battery life, lack of dual mic, and the chip was just a tad underpowered for the display it was carrying resulting in faster power drain even on simple tasks.
But now there is a new game changer again...
the O+ 8.15
set to be released tomorrow at 9,990 promo 12,990 regular price
more and more it closes the gap on the P770 essentials i come to rely on with lovely upgrades thats hard to pass up at 8.4mm thin, thats actually slimmer than the Galaxy S3.

leapfrogging other makers by including 4.2.1 out of the box with some respectable specs under the hood at under 13k is remarkable. i'll be running a more complete hands-on review of the unit when it arrives tomorrow. but on paper the one thing i can't ignore is the underwhelming battery capacity which is among my top requirements. got to love the Lenovo P770 for its stamina
