While we wait for foldable phones from Samsung and Huawei to go on sale, Sony is apparently working on flexible display technology, but in this case we're talking about a rollable phone rather than a foldable one. Tipster Max J from AllAboutSamsung says he has real information about the prototypes being built at Sony. Please note that we're talking about prototypes here, so details could change before a general release. A rollable phone from Sony could be unveiled by the end of the year, rumor has it, with a Snapdragon 855 chipset and Qualcomm X5 modem 50G chip. With these features, don't expect a cheap starting price. Given the lack of hard evidence to back up these claims, we wouldn't bet on your home just yet. However, this is an interesting index of the next step that Sony and the rest of the industry should follow.
