Archos is a French company with its main focus being the European market. The company is well known due to their re-branded smartphones.
Archos already have re-branded some Nubia phones, like the Nubia M2, which became the Archos Diamond Alpha. Now the company is going further and turned the recently announced Nubia Z17S, hence becoming Archos Diamond Omega.
As a result of this, the Archos Diamond Omega retains all the specs found in the high-end variant of the Nubia Z17s. There no differences apart from the Archos logo on the phone’s rear.
