The Lumia 535 is the first handset from the line to dump the Nokia brand. The Microsoft Lumia 535 made its debut Monday, notable for being the first Lumia handset to lose the Nokia label. Microsoft bought Nokia’s phone business in April for $7.2 billion in a deal that allowed the division to continue to produce phones with the Lumia name adorned on them. The deal also allowed Microsoft to keep using the name Nokia on new phones for a brief time, but that brand is being phased out in favor of the name Microsoft Lumia.
