The foldable phones are coming, that much we can all agree on. Multiple manufacturers have announced their intentions to produce a folding device, Google is building support for them into Android, and we’ve even seen the first such phone actually make its way to market in China. At Mobile World Congress (MWC) in Barcelona next month, rumors suggest more announcements are in store from companies ranging from Huawei to Motorola and even Oppo. But outside of an implicit agreement that folding phones are going to happen, there’s close to no consensus about what the best form for them actually is. Through various early teases, announcements, and patent filings, we’ve seen a range of different form-factors proposed. Ask four different manufacturers what form their folding phone will take, and you’ll get four very different answers.
