Is not flagship phone gap should be 2 years 0r 18 months instead of 1 year

Personally, I think that 2 years gap is just nice, but if they got all new fresh idea each year and also want to compete who is the best among the best to provide new innovation, nobody can stop them.

So Huawei just launched with 3 cameras, then soon Samsung with 4 camera? Lol maybe

I was just thinking about the camera thing you mentioned - quadruple cameras? Lool.
