There just aren't other companies that can roll out a feature like 3D Touch and make it work in a way that suggests the creation of entirely new interface paradigms, and every other phone maker needs to figure out exactly why Apple's cameras are so consistent before they can really compete." [58] Samuel Gibbs of The Guardian commented that the phone "has the potential to be the best smaller smartphone on the market, but its short battery life is deeply frustrating" and described the camera as "not leagues ahead of the competition anymore". [59] Tom Salinger of The Register praised performance, noting that "we're now using phones with the performance of current PCs", but described 3D Touch as "just a glorified vibrator" and "no good ... you still don't know quite what's going to happen until you try it".
