The Foldable Smartphones

Like the old-school clamshell phones of the 1990s, your next smartphone can flip open to reveal its screen and fold up when you are ready to put it away.

The question is: is it really something that we like anymore?

Tech firms like Samsung, Motorola and Huawei definitely hope so. A few years back, many of us realised that the smartphones we had were still really fine, and their replacements were just marginally stronger, but before upgrading, we kept on to our phones longer and longer. Which damages the bottom lines of those businesses.

So handset vendors flood us with so-called foldables in an attempt to come up with something fresh and innovative that would make us spend our dollars. They include the 1,00,000 rupees Galaxy Z Flip from Samsung, which was launched on Tuesday, and the 1,05,000 rupees Motorola Razr from Lenovo, which was launched last month.

The science of folding screens is definitely interesting and worth keeping an eye on.But the consensus among consumer technology experts , hat before even considering buying one, you and I should definitely wait for the products to mature. Here's the reason.

For these lightweight screens that are used with these foldable phones, one of the fascinating aspects about an OLED screen is that there is no glass pane on top of it. It sounds intuitive, yeah, but it's not actually an obvious thing. So all it means is that when you touch and communicate with that device, when you interact with that screen, when you interact with the screen, you don't touch a glass pane. The real computer itself, which is a small plastic monitor, you touch.

The Pros -

A foldable phone's primary advantage is that you can appreciate a wide screen that takes up less room in your pocket.

Cons Are Mostly There

With many downsides, Foldables arrive.

Foldable gadgets rely on versatile OLED, a much thinner display technology than conventional screen panels. In order to make our phones and smart watches slimmer, gadget manufacturers have used flexible OLED for years. For instance, the Apple Watch uses a flexible display, but since it is protected by solid sapphire crystal, it is not bendable.

You have to lose any rigidity to make devices bend. In general, flexible foldable screens are covered with a rubber coating that can be scratched or breached more readily than the durable glass that covers conventional phone displays. (Samsung said its Z Flip uses an ultra-thin, foldable glass that will allow you to fold 200,000 times and unfold your phone.)

It remains to be known, but not least, if the electronic hinges of folding phones are going to survive the time test. Early reports of possible hinge issues on the Razr are available: some reviews said the hinge is incredibly close, rendering it cumbersome to fold and flip the phone open. After 27,000 cycles using a robot, CNET, the software review site, said the hinge of its Razr research device broke.

Bottom line -

It's too early to say if it would work for foldable phones. Technology would likely become cheaper and more stable in a few years.
