Take this rumored leak with a grain of salt as Motorola still hasn't officially confirmed the news.
We have already come across the leaked news of Motorola working on its third generation handset. The front features of the phone is much similar to the earlier launches of Moto G but the rear seems to give a fresh look. The camera, flash and the Motorola Logo are all together connected via a metal or plastic strip which overpowers the conventional textured back look.
The sources doesn’t reveal any new specifications, but from what we have heard so far, the Moto G (2015) won’t be bringing in a lot of improvements over its predecessor. It is expected to feature a 5-inch display, Snapdragon 410 processor, 1GB RAM, 8GB internal storage along with microSD card slot. It is also probable to feature a 13-megapixel rear camera, 5-megapixel front-facing camera, and a slightly bigger 2,300mAh battery. It is most likely powered to run on an Android 5.1.
As with all such leaks, we would advise you to take it all for an assumption. As for a launch time frame, just like last year, Motorola could be looking at unveiling the third generation variants of the Moto X, Moto E and Moto G in September this year.
