The X4 is Bluboo’s first 4G-supported product. It uses a combination of MediaTek’s new MT6582M (quad-core processor with 1.3GHz frequency) and the MT6290. According to official reports, the Bluboo X4 supports TDD-LTE and FDD-LTE 4G internet as well as WCDMA/TD and GSM.
Despite supporting many kinds of internet networks, the X4 is not a high-end phone. It has an IPS display screen that is only 4.5 inches and only has FVGA resolution (854 x 480). Its memory is not that special either. It has 512M RAM and 4GB ROM. It sport a 2mp/5mp dual-camera and its operating system is the new Android 4.42 kitkat.
It’s worth mentioning the Bluboo X4’s design. The frames are split in the middle by a black line. Its measurements are 134.3×65.5×9.6mm.
Like the X2, the X4 should be released overseas first. Whether or not it will be released in China remains to be seen.
