South Korean technology launched in 2019 the Galaxy S9 generation. They are two very conservative high-end Android smartphones and identical to the previous generation. However, by 2019 Samsung should surprise with bold Android devices.
Firstly, by 2019 we will begin to see the fingerprint reader under the screen. Something we have already found in the Huawei Mate 20 Pro, among other recent smartphones. Therefore, for the year we will see a redoubling of efforts on the part of Samsung.

First and with the fingerprint reader already under the screen, the South Korean is already planning the next step. Therefore, it should not only go through the folding smartphones and screen as well as a new approach to the front cameras.
In this sense we now have an indication that Samsung is developing and testing a way to place the front camera under the screen. That is, placing the self-camera already built into the smartphone display behind the screen. Something that would transform the front panel look of Android smartphones.
Samsung tests new approach to notch concept
Secondly, it becomes very easy to imagine an Android smartphone where the screen essentially occupies the entire front panel. A device in which the camera does not oblige manufacturers to implement a notch or single mirror on top of it. An Android smartphone where the screen doesn't have to wrap around the camera and various sensors. An Android device where the screen can be the sole protagonist of the front panel without distractions or design imperfections. This is Samsung's current ambition.

Thirdly, we have seen several manufacturers trying to work around this on their Android terminals. Take a look at the Xiaomi Mi MIX 3 which will have a full sliding tab on which will be the selfie cameras as well as the necessary sensors. Look at the thousand and one smartphones with a notch to host the front camera and its sensors.
Next generation of high end Android will be able to implement the news
Imagine now a smartphone that does not need any of these solutions. Where the front camera is no longer a hindrance nor does it require curious maneuvers in the design and mechanics of smartphones.
That's exactly what Samsung will be doing by testing various prototypes of various Android smartphones with a new approach. All of this so that Samsung never has to "surrender" in the fashion of single or notch.
However, this technology will still be at a very early stage, with no proven success or viability. Still, it will not be foolish to say that by 2019 we may see some already functional prototypes.
In short, this technology could well hit the Samsung Note 10 by mid-2019 or, more conservatively, by 2020.
