A new vivo phone just passed the Chinese certification, 3C, with a model number V1922A and the interesting part is the charger that came with it. It's rated at 44W suggesting that this is a high-end device we are dealing with here. It's only natural for vivo to implement its fast charging tech into its top-shelf phone so we have a very good reason to believe it's a NEX successor - perhaps the NEX 2? Unfortunately, this is the first time we hear about a phone with this model number so we can't be entirely sure. We still need more information to paint a full picture and it's only now...
