Samsung Galaxy S9: What happens if the phone gets these six features?

We have compiled a long list of features that are rumored to include Samsung Galaxy S9 when it launches next month at the Mobile World Congress, the program for everything related to mobile devices.

Meanwhile, at CES, the show of every kind of technology (not just mobile), we saw many innovations that could find their way into future phones like the Galaxy S9.

Realistically, most of these features would show up far ahead, if they do, but at least one new technology we saw is a strong bet to appear on Samsung's first phone for March. If it does, it would fix the most maddening fault of the Galaxy S8.

First screen fingerprint sensor

An unpublished and unpublished phone from the Chinese Vivo is the first to demolish a fingerprint reader embedded in the screen . Technically, the sensor lives below the screen. We met with Synaptics, the company that created the fingerprint reader, to verify it.

Why it's important : It was rumored that this kind of technology was in old Samsung Galaxy phones and in the iPhone X. It was not, but it is rumored to be for the Galaxy S9. A fingerprint reader on the screen allows device manufacturers to use the entire phone screen for their applications, without reducing the active area to make room for a physical button.

A screen reader would also allow Samsung to solve the obvious problem of its fingerprint reader uncomfortable and difficult to place on the back of the Galaxy S8 and the Galaxy Note 8 – all the way to the right of the lens the camera.

Flexible electronic and roll-up screens

This 65-inch TV panel is wound up in a casing: could a phone do that too?

Sarah Tew / CNET

LG made a television screen that physically rolls down on his housing when he finishes watching it, so he is not looking at an ominous black mirror.

It's too early for phones to follow suit, but the fact that technology exists in a consumer product gives us the hope that one day it can be miniaturized and applied to phones. The dreams of folding and rolling screens have been a moon-throwing project for R & D departments for years.

We have seen concepts such as the 2017 C-Plus wristband phone, but now we are seeing small steps. Samsung, however, promised a foldable phone sometime in 2018. We hope it's better than the ambitious ZTE Axon M that is deployed in a mini tablet.

The challenge : While Samsung and LG made flexible displays successfully years ago, we've also seen flexible glass, getting components like batteries and chips to bend and flex is still not sustainable.

Phones that power the docks … again

The Samsung DeX docking station allows you to use your Galaxy phone as a computer, by displaying the contents of your phone on any large monitor.

But the game brand Razer takes the concept a step further by using the Razer phone as a trackpad and processing engine for a laptop base that would not otherwise be turned on without the phone. They call it the Project Razer Linda .

Play in progress:
Look at this:

A hypothetical home for the Razer phone


Why it could be great : phone manufacturers have tried it since 2011. Asus did it too, using a phone to feed a tablet. The technology did not understand. While some of us maintain some healthy skepticism that Project Linda will not be able to provide the same power or experience to make a laptop with phone fuel worthwhile, the idea to use a phone coupled by more than just its processor is brilliant, and we would like Samsung to be applied to phones like the Galaxy S9 or Galaxy Note 9.

Telephones that charge other phones

Chris Monroe / CNET

Resistant Catmaker showed the S41 a phone with a huge 5,000 mAh battery that can be used to charge other phones. Then, say your friend needs a recharge. Not only can you become your power hero, but you can also set a limit to the amount of charge you can extract.

Cat does not even use the new USB-C technology that makes it possible to transfer data and energy between devices; the S41 still uses Micro-USB.

This is a trick : battery life is very important for buyers, so phone manufacturers burst trying to make devices that last longer and charge faster, so they can get and keep as much power reserve as possible.

But having the option to help someone with a quick recharge of the phone would help set the phone apart from the crowd, especially if the phone owner can recharge his smart device before his friend, either wirelessly or by a cable.

Shutter that physically blocks the webcam


Now he sees you, now he will not.

Josh Miller / CNET

Slide a small switch on Lenovo Smart Display (the new Google shot on a smart screen for your home) and a shutter on the front camera, which gives you a very clear guarantee that nobody can see you. Lenovo also added the function to two new laptops .

Security is a hot topic, especially in a year marked by major data breaches and hackers. If you find yourself putting duct tape on your laptop's webcam or if you know someone who does, you understand the appeal of this change.

How likely is it that this will reach the phones? : quite unlikely. Phone users use the front camera a lot for selfies and video chats. A shutter would be an additional expense and another component that could be broken.

Designers would also have to place it on the body and, even if it is thin, it would take up some space; Not too convincing when it comes to making the devices thin and light.

Sensors that track your food and your health


A sensor on your fingernail? Ick. But your phone makes sense.


L & # 39; Oreal provided us with a nail wear sensor that measures your exposure to harmful UV rays.

Motorola announced a Moto Mod accessory that measures vital elements such as its heart rate temperature and blood pressure.

And a company called Osram showed an LED chip that could turn your phone into a scanner that measures the chemical composition of your food and medicine. (We have seen something similar integrated into a telephone last year in fact.)

Sensors make sense : Sensors are very important for photography, facial recognition, scanning Fingerprints, security and physical fitness Take up space and add expense, but most of the right ones will greatly expand the power of a phone.

Samsung's high-end phones are already measuring your heart rate, but expanding to other health-related activities, such as taking your temperature, will attract many … as long as the readings are accurate and convenient to take.
