When HMD released Nokia 6 moods were optimistic, because people thought that Nokia 6 will be able to rival with other Samsung's or LG's devices. On paper phone looked quite okay, but not so powerful as it was thought previously. The main disadvantage was its processor - Qualcomm Snapdragon 430, and Nokia wants to solve this problem during the coming year by releasing upgraded version of Nokia 6.
It's rumored that Nokia 6 in upgraded version will have Qualcomm Snapdragon 660 processor. Apart from processor device will receive bigger amount of internal storage (32GB) and RAM (4GB). Probably Nokia 6 will be presented during January 2018, but it's unknown when phone will be available for purchase.
