Out of the trio of Sony smartphone models which have been given the nod of approval by Postel, one of them could very well be the Sony Xperia Z4. So far, we have been furnished with the devices’ model numbers, although it would not be too far off the mark to come up with some assumptions of our own.
The E6533 is interesting to look at – with the Xperia Z2 bearing the model number D65xx, alongside the Xperia Z3 carrying D66xx, hence it would be interesting to note that the letter would denote the year of its release, hence “E” would be for 2015. Elementary, my dear Watson! Hence, should the alleged Xperia Z4 be certified already, you can be sure that a release is not too far off from the horizon.
