The tweet from @S_leak states that the Galaxy J (2016) will be powered by the unannounced Exynos 3457 chipset. The latter contains a quad-core CPU and the Mali-T720 GPU. 1GB of RAM is inside and Android 5.1.1 is pre-installed. The OG Galaxy J1 is driven by a dual-core 1.2GHz CPU with the Mali-T400 GPU. 512MB of RAM is aboard.
The original Galaxy J1 was launched last February, so it wouldn't be too far out of the question to expect a sequel to be unveiled soon. Still, we do suggest taking this story with the proverbial grain of salt. Perhaps we will soon see the Galaxy J1 (2016) certified by the FCC, or TENAA. If that happens, you will be able to put away the salt shaker.
The Samsung Galaxy J1 (2016) is apparently on the way
