The Samsung Galaxy Grand 2 was announced late last year but only now we find out that the mid-range 5.25" Android phone has an LTE version. That version carries the model number SM-G7105 (model numbers for LTE-enabled devices end in 5).
The device is not official yet, but its user manual (PDF) and its SAR information have been uploaded to the Samsung site. The SAR search tool returns two devices – G7105 and G7105L – but the L model hasn’t been tested yet (it's probably a carrier-specific version).
Skimming through the user manual, nothing seems to have changed in terms of specs but then there's no info on the chipset (which likely has changed). We're waiting for the official specs to go up to confirm if there have been changes to the quad-core chipset.
The Samsung Galaxy Grand 2 also comes in the G7102 version, which is a dual-SIM model, but that's a 3G-only device.
