Huawei was first to announce a phone with pressure-sensitive display - an upcoming edition of the Mate S phablet - and arguably it uses the Synaptics 3700 series to achieve that, calling the technology with the street name Force Touch. The reason that the Mate S version with pressure-sensitive screen is not yet on the market? "Synaptics has been working closely with leading global OEMs and LCMs to deliver this new dimension in touch with force-enabled smartphones expected to ship in early 2016," says the company in its press release.
Well, Samsung is allegedly also on the light-tap-and-hard-press bandwagon, and the source says it will be incorporated into the Galaxy S7, which wouldn't be hard to believe, given its release timeframe for Q1, and the fact that the iPhones already have their 3D Touch tech built in, so the competition in the pressure-sensitive display field is only going to grow up from here.
