Apparently, in recent years, the race for the title of the thinnest smartphone has stopped – manufacturers release devices just without going beyond the usual framework (on average, it is about 7-10 mm). And what’s the point of making a smartphone as thin as possible if it’s inconvenient to hold it in your hand? In this review, we present the thinnest smartphones among the popular models on the market. And note the fact that some of the manufacturers only take into account the thickness of the body, while ignoring the camera module that extends beyond the body.
