Sony's Xperia X lineup didn't seem to have attracted too much appeal from customers, but what matters is for the Japanese company to redeem itself in the eyes of its most loyal fans.

The next devices coming from Sony are likely to be presented next year at Mobile World Congress, which set to take place between February 27 and March 2. This means that we are still four months away until the supposedly reveal of the next Xperia phones.

However, the first details on unannounced Sony smartphones have just emerged at the Eurasian Economic Commission. Two presumably Xperia handsets that go by the model number G3112 and G3121 have been spotted, but no additional details on specs are available yet.

The only thing that makes us believe these phones will be revealed next year at MWC is the model number, which follows the same pattern as the previous phones introduced by Sony at the same trade fair: Exxxx in 2015, Fxxxx in 2016.
