How to use the new fingerprint reader to unlock Galaxy S10, S10+, and S10e?

· Leave a Comment

use the new fingerprint reader to unlock Galaxy S10, S10+, and S10eSamsung dramatically changed the fingerprint reader (fingerprint sensor) on Galaxy S10. An in-display ultrasonic fingerprint reader is used in Galaxy S10 and Galaxy S10+.

With the removal of Iris scanner on Galaxy S10, many owners will have to use the fingerprint scanner to quickly unlock Galaxy S10.

This Galaxy S10 how-to guide explains how to register fingerprints and use the fingerprint reader to unlock Galaxy S10, S10+, and S10e.

What’s new in Galaxy S10 fingerprint reader?

Galaxy S10 (and Galaxy S10+) is the first smartphone with an in-display ultrasonic fingerprint reader, which is one of the most notable new features of Galaxy S10.

Instead of scanning your fingerprint using capacitive or optical methods, ultrasonic fingerprint sensor uses sonic pulse waves to find out the 3D structure of your fingerprints.

Similar ultrasonic technology has been used in biomedical imaging in hospitals for decades and saved many lives.

Generally speaking, or technically, the ultrasonic fingerprint reader can get the real 3D info of your fingerprints and therefore it could potentially be far more accurate than the traditional capacitive fingerprint reader.

Do not confuse this in-display ultrasonic fingerprint reader with the in-display optical fingerprint ones (as in a few OnePlus and Vivo phones). The optical fingerprint reader is the slowest one. It is even slower than the traditional capacitive fingerprint reader.  And the optical one is the least secure because it is essentially a kind of 2D photo recognition.

For Galaxy S10e, a traditional capacitive fingerprint sensor is mounted on the power button as illustrated in Galaxy S10 layout. The position is at least better than the fingerprint on Galaxy S8 (see Galaxy S8 layout) or S9 (see Galaxy S9 layout).

What are the major limitations of the in-display ultrasonic fingerprint reader on Galaxy S10 and S10+?

Although the in-display ultrasonic fingerprint sensor sounds cool and is actually the most secure (accurate) fingerprint reader, there are some inherent limitations of this new sensor on Galaxy S10:

  • Many screen protectors will not work nicely with the in-display fingerprint reader. The sonic waves are affected by the air between the screen and screen protector. Therefore the sensor may not function properly even if a small air bubble is trapped by the screen protector.
  • You need to know where to press your finger.
  • The matching sensitivity is not rocket science. If Samsung set the sensitivity too high, you may have to press several times. If it is set too low, it will not be secure.

So, as explained in the top 10 disappointing and missing features of Galaxy S10, I prefer the fingerprint sensor on Galaxy S10e.

How to register fingerprints for the fingerprinter reader on Galaxy S10?

To use the new fingerprint reader to unlock Galaxy S10, you need to register your fingerprints first.

The procedure of registering (adding) fingerprints is identical for all 4 Galaxy S10 phones. But in this guide, we will use Galaxy S10 for the illustration.

Understand the layout of Galaxy S10, S10+, and S10e

· 2 Comments

Galaxy S10 layout (layout of Galaxy S10, S10 Plus, and S10e)You need to understand the Galaxy S10 layout to properly use your Galaxy S10, S10+, or S10e.

The 4 models of Galaxy S10: S10, S10+ (S10 Plus), S10e, and S10 5G, share similar, but not identical design. The layout of these 4 Galaxy S10 phones is slightly different.

Because S10 5G has not been released yet, this Galaxy S10 guide will explain the layout of Galaxy S10, S10+, and S10e.

Why do you need to know about Galaxy S10 layout?

Galaxy S10 is not a revolutionary product. So, you can find some similarity between the Galaxy S10 layout and Galaxy S9 layout.

But the difference is also obvious.

Exploring the Galaxy S10 layout allows you to:

  • Locate the buttons: Power button, Bixby button, and volume buttons.
  • Locate the ports including multifunction (USB Type C) port and headphone jack.
  • Locate the SIM card tray.
  • Locate the antennas.
  • Locate the cameras and sensors.
  • Locate the wireless charging coil.
  • Locate the speaker and microphones.
  • Locate the fingerprint sensor.

Anyway, you should spend a few mins on understanding the Galaxy S10 layout. It will pay off immediately when you avoid some mistakes (e.g., piercing the microphone on the top with the SIM card ejection pin) or learn to use some special features or tricks.

The major differences among Galaxy S10 layout, Galaxy S10+ layout, and Galaxy S10e layout

The differences in specifications of Galaxy S10, S10+, and S10e are reflected in the device layout.

Here is the list of major differences among Galaxy S10 layout, Galaxy S10+ layout, and Galaxy S10e layout:

  • Size.  Galaxy S10+ is the largest and Galaxy S10e is the smallest. Galaxy S10 lies in between.
  • Front camera and the hole.   Galaxy S10+ has two front-facing cameras. The hole in the infinity O display is elongated and larger than that in the other two siblings.  Galaxy S10 and S10e only have one front-facing camera.
  • Rear cameras. Both Galaxy s10 and S10+ have 3 rear cameras. Galaxy S10e only gets one.
  • Fingerprint scanner. Both Galaxy S10 and S10+ have an in-display fingerprint scanner. The fingerprint scanner in Galaxy S10e is mounted on the power button.

The relative locations of the buttons, sensors, antennas, ports, speaker and microphones, SIM card tray are almost identical.

Layout of Galaxy s10+ (Galaxy S10+ layout)

The front view of Samsung Galaxy S10+ layout is shown below.

In the front, you can find:

  • Touch screen

The touch screen occupies about 90% of the front side of Galaxy S10+.

You can use various Galaxy S10 touchscreen gestures to interact with the phone.

  • Edge screen

Edge screen is part of the touch screen. You can activate either the left side or right side of the touch screen as edge screen.

You can use some special edge screen features like edge lighting and edge panels. The edge screen on Galaxy S10 is similar to Galaxy S9 edge screen. You may refer to this guide on how to use the edge screen.

  • Fingerprint scanner

Top 10 disappointing or missing features of Galaxy S10

Top 10 disappointing or missing features of Galaxy S10Galaxy S10, S10e, S10+, and S10 5G set the standard for the flagship smartphones in 2019. There are many new features and improvements in both hardware and software.

But they are far from perfect. There are some missing features in all 4 Galaxy S10 phones. Some features may also be very disappointing.

This post summarizes the top 10 disappointing and missing features of Galaxy S10.

#1. The most disappointing and missing feature of Galaxy S10:  Iris scanner is gone

Iris scanner was first introduced in the explosive Galaxy Note 7. Most owners did not get the chance to try it before the phone was recalled, and re-recalled.

In Galaxy S8 (and S8+), the iris scanner works reasonably well. Many Galaxy S8 owners actually used the iris scanner because of the awkward location of the fingerprint scanner.

Obviously, the iris scanner was improved dramatically in Galaxy S9. It is faster than all other unlocking methods including the fingerprint scanner because of the less-ideal location and smaller size of the fingerprint scanner. If you are using a case or cover for Galaxy S9 or S9, it is not easy to reach the fingerprint scanner.

When more and more owners realized and started to enjoy this unlock feature, Samsung removed it in Galaxy S10.

None of the 4 Galaxy S10 models has the iris scanner.

The reason given by Samsung is the lack of bezel space for the iris scanner.

But if they can punch a hole for the front-facing camera(s), why cannot punch another hole for iris scanner? Here is the Galaxy S1o layout.

#2. The most demanded but missing feature of Galaxy S10:  freely remapping Bixby button (key)

Bixby is quite good if you compare it to Siri.  But if you compare it to Google Assistant, which is shipped with all Android Pie phones, Bixby is far behind.

But Samsung pushed Bixby so hard that a dedicated hardware Bixby key was introduced in Galaxy S8 and S8+, and all subsequent Galaxy phones get the button below the volume keys.

The most annoying part is that you cannot remap the button for other more useful features. e..g. Launching the camera or using it as a camera shutter button, if you have no intention to use Bixby, or have no intention to use the Bixby button.

In Galaxy S8 and S9, you can disable the Bixby key by letting it do nothing when pressed. If you turn off Bixby Voice in Bixby settings, the long press gesture of the Bixby key will also be deactivated and do nothing.

But in Android Pie update for Galaxy S9, S8, Note 9, and Note 8, Samsung does not allow you to disable Bixby button. You have to choose a single press or double press to launch Bixby. You cannot assign “do nothing” to either of the gesture. Even worse, the long press gesture will always launch Bixby Voice directly. And you cannot turn off Bixby Voice!

Top 10 new features of Galaxy S10

The top 10 exciting new features of Galaxy S10

· Leave a Comment

top 10 new features of Galaxy S10As Samsung’s flagship smartphones in 2019, Galaxy S10 (include Galaxy S10e, Galaxy S10+, and Galaxy S10 5G) packs the latest technology Samsung has or can access. So, you can expect some exciting new features of Galaxy S10.

It is impractical to discuss all new features of Galaxy S10 in one post because of the long list of the new features of Galaxy S10. For the hardware specifications, you may check this post. For Galaxy S10 layout, you may check this guide.

In this post, we will explain the top 10 most exciting new features of Galaxy S10 most owners will enjoy: Dynamic AMOLED with HDR 10+, infinity O display, ultrasonic in-display fingerprint scanner, Bixby Routine, ultrawide camera, wireless PowerShare, Android Pie and One UI, Digital wellbeing, recording 4K UHD video with HDR 10+, and fast wireless charging 2.0.

Of course, Galaxy S10 is far from perfect. There are also some disappointing and missing features of Galaxy S10 as discussed here.

The most exciting new feature of Galaxy S10: Dynamic AMOLED with HDR10+

Samsung flagship phones traditionally have the best display.  No other smartphone makers can match Samsung when the display is discussed.

In Galaxy S10, Samsung updates its Super AMOLED to Dynamic AMOLED.

So, All four Galaxy S10 devices (Galaxy s10e, Galaxy S10, Galaxy s10+, and Galaxy S1o 5G) all have a Dynamic AMOLED screen.

This AMOLED is somewhat different (and better) from the screen in Galaxy S9 and other Galaxy phones.

In a nutshell, the Dynamic AMOLED on Galaxy S10 supports:

  • Higher brightness (up to 1200 nits peak luminance). You can use the screen even directly under the sunlight.
  • Larger dynamic range.  From black to white, you can see more “colors”.
  • HDR10+.  In addition to static dynamic metadata, HDR10+ also supports dynamic metadata. Therefore the brightness boundaries can be set and changed on a frame-by-frame basis. Galaxy S10 (all models) is the only smartphone certified with HDR10+ up to now (February 2019).
  • Lower blue light emission.  You will feel more comfortable to use the screen in all lighting conditions. Galaxy S10 screen (all models) was certified by TÜV Rheinland.

Dynamic AMOLED is probably the most exciting new features of Galaxy S10. It is available in all four models: Galaxy S10, Galaxy S10e, Galaxy S10+, and Galaxy S10 5G.

The most innovative workaround of Galaxy S10: Infinity O display

All smartphone manufacturers are working hard to reducing the bezels.

But there is a limit because of the front-facing cameras.

So far, to solve this problem, other smartphone manufacturers follow iPhone X: using a notch, which can be quite ugly (subjective).

Samsung finds an innovative workaround for this issue: punch a hole for the front-facing cameras.  It looks far better than the notches.

And in Galaxy S10, Samsung calls it infinity O display. All 4 Galaxy s10 models use infinity O display. Galaxy S10+ and Galaxy S10 5G get a bigger (and elongated) “hole”.

The most talked new features: the ultrasonic in-display fingerprint scanner

Specifications of Samsung Galaxy S10, S10 Plus, S10e, and S10 5G

Get to know Galaxy S10 specs (and Galaxy S10+ specs, Galaxy S10e specs, and Galaxy S10 5G specs)

· 3 Comments

pecifications of Samsung Galaxy S10, S10 Plus and S10eAlthough software plays a more and more important role in today’s smartphones,  many potential Galaxy S10 buyers are still eager to know what are the specifications of Galaxy S10.

Based on early leaks and rumors, specifications of Samsung Galaxy S10 are almost certain in most aspects.

This post summarizes the key specifications of Samsung Galaxy S10, S10 Plus, S10e, and S10 5G.

How many models of Galaxy S10 will be?

Almost certain, tThere will be 3 are 4 Galaxy S10 models with slightly different specifications:

  • Galaxy S10.
  • Galaxy S10+ (Plus).
  • Galaxy S10e.
  • Galaxy S10 5G (in selected markets only).

Galaxy S10 is targeting mainstream users. S10+ (S1o Plus) is targeting hardware enthusiasts, who want to get everything available. Galaxy S10e is targeting buyers who want a smaller phone.  All these 3 Galaxy S10 models will be available globally on March 8, 2019.

Galaxy S10 5G is the only 5G capable phone in the market now. It will be available in Q2 2019. Because the 5G network is only available in very limited regions and carriers, Galaxy S10 5G will be available in selected regions.

The specifications of Galaxy S10, S10+, S10e, and S10 5G  are slightly different.

Of course, Galaxy S10+ will be the most expensive one among the three (the pricing of S10 5G is still not available now). S10e will be the cheapest.

Key features in specifications of Samsung Galaxy S10, S10 Plus, and S10e

Samsung Galaxy 10 is the 1oth generation of Galaxy S series phones.  Samsung needs to use this historical device to showcase its leadership in the oversaturated smartphone market.

In addition to the annual upgrade of CPU, there are some interesting and major changes in Galaxy S10 specifications.

The infinity display will be pushed to the limit: the top bezel is not enough for the camera lens and a hole in the display has to be punched.  So, Samsung just named it infinity O display.

So, instead of a notch, you will see the punched area for the front cameras as shown below.

Key features in specifications of Samsung Galaxy S10, S10 Plus, and S10e

The fingerprint scanner will now be embedded under the screen in Galaxy S10, S10+, and S10 5G. And it uses ultrasonic 3D scanning technique.  There is no button or cutout for the fingerprint scanner.

On Galaxy S10e, the fingerprint scanner will be embedded in the power button on the right side of the phone.

Wireless charging has been a standard feature since Galaxy S6. Now, Samsung will add the wireless PowerShare (reverse wireless charging) into Galaxy S10.  You can use your phone as a wireless charger to charge other devices.

Galaxy S10, S10+, S10e, and S10 5G will be powered by Android Pie with the new One UI.  Actually, if you have updated your Galaxy S9, S9+, or Note 9 to Android Pie, you are using the One UI already.  You may enjoy the night mode, navigation gestures, the new Recents panel, and some other new features.
