Will 2019 enter the era of folding mobile phones? Mobile phone is flat, cool to no friends

What kind of mobile phone are you going to buy next?
Better camera, longer battery life, or foldable mobile phone?
This new high-tech product folds up to the size of an ordinary mobile phone, and when it is rolled out, it is equivalent to a tablet computer. There is no need to worry that the screen is too small to use.
Samsung, Huawei and Motorola will soon launch their own foldable mobile phones. Whether you buy them or not, 2019 will be a brilliant year for foldable mobile phones.

Other than sharper screens, better cameras, or improved battery life, there really haven't been any massive changes to the structure of the smartphone in over 10 years now. But it seems like 2019 is set to buck the trend.

Recently, we've had squeezy phones, curved phones, notched phones, and now, we are getting bendable phones. Unlike the gimmicks of years past, these might have some value.

Companies like Samsung and LG have shown off flexible displays at trade shows for years, leading some to believe that there would be a future where we'd roll up our phones like a newspaper.

That future has been slow-moving, but this year at the CES electronics trade show in Las Vegas, electronics manufacturer Royole showed off the FlexPai, which it calls the first “fully flexible display” electronic device. In plain English: that's a smartphone that folds out into a tablet.

Even though it's being folded over itself, the FlexPai's display doesn't snap or bruise—which, definitely don't try with your current phone's display. It's meant to replace the need for two devices, by being two devices in one. A developer model of the phone is available now, for a paltry $1,318.

Samsung, the world's largest phone manufacturer, plans to release a folding phone this year, which it teased in late 2018. It showed off a prototype of the device, seemingly encased in a housing to hide its real shape, which seems to work similarly to Royole's, except that the screens will be on the inside, like a book.
Science and technology lead the times and the times lead the trend. The times are developing and science and technology are progressing.
