Lenovo-owned Motorola has reportedly commenced testing on 2016 series Moto X flagship smartphone.

A Twitter user, Roland Quandt, has spotted the Moto X3 on Zauba.com, an Indian based export-import logistic company website. In the manifest, we see that two units of Moto X3 have been imported from the U.S. to New Delhi (India) for testing purpose. It also reveals that device features 5-inch screen with single-SIM slots.

Other key features such as display resolution, processor, RAM, storage and camera are still scarce at the moment. But, we expect these details to surface online sooner as the company has already announced, it will be unveiling three devices — entry level Moto E (2016), mid-range Moto G (2016) and a high-end Moto X — later this year.

Just a week ago, two Moto E series models — XT1700 and XT1706 — were spotted on GFXBench performance testing site, revealing their key features.

Both the devices were found to have same spec-list. They reportedly featured 5-inch HD screen, 1GHz MediaTek (MT6735P) quad-core CPU, Mali-T720 graphics engine, 16GB inbuilt memory, 2GB RAM, 8MP camera on the back and 5MP snapper on the front. Many believe that  XT1700 and XT1706 are single-SIM and dual-SIM variants of Moto E (2016).

Going by the aforementioned reports, Lenovo might be in the final stages of Moto series development.

If history is taken as any indication, Lenovo is expected to pull the wraps of the new generation Moto E and Moto G series in a couple of months and the marquee Moto X series a month later.
