Oregon Based US Electronic Manufacturer, InFocus is certainly preparing a high-end phablet with some top of the range specs. The phablet in question is the InFocus M5503 which has been put through its paces on GFXBench.
The InFocus M5503 packs a 5.7-inch LCD display, 1920 x 1080 pixels resolution, a true octa-core Mediatek MT6752 cortex A52 CPU which clocks at 1.7GHz, ARM Mali-T760 GPU, 2GB of RAM and 16GB space of internal storage (13GB user accessible).
The device is listed as having a back and front facing 12MP camera (maybe 13MP); both cameras are capable of recording 4K (3840 x 2160 pixels) videos. The InFocus M5503 only supports Single SIM; supports Wi-Fi, Bluetooth; GPS and 3G connectivity. It also uses accelerometer, gyroscope, compass, proximity & light sensor options; it would run on Android 4.4.4 Kitkat OS.
One point of interest is the front facing 13MP which can also record 4K video. We hope the device goes official soon so as to get the full detailed information.
