With the pace of smartphone evolution moving so fast, there's always something waiting in the wings. No sooner have you spied the latest handset, that there's anticipation for the next big thing.
Here we look at those phones that haven't yet launched, the upcoming phones for 2018. We've now taken Sony's latest - the Xperia XZ2 Premium - out of this list because we now got full details on it even though it won't be launched until the Summer.
We'll be updating this list on a regular basis, with those device rumours we think are credible and exciting.
