mobiles are mature products and the players are strictly in cash-cow or market share mode. nothing of importance is changing.
I've got an iphone se and an iphone 4 and you can't tell me that's the most they can do for 6 years of product development by one of the richest companies in the world. (yes i know that it's faster with more a and more b and more c etc)
Apple needs to drip feed improvements over the next x years to keep sales up so we can't expect anything game changing.
"The Others" are trying this and that but nothing seems to be sticking, probably not able to drive consumer desire enough.
so if nothing is happening, what is the post-phone next-big-thing to get into?
