How to use Galaxy S10 wireless PowerShare to charge other devices?

simon · Leave a Comment

You can use Galaxy S10 wireless PowerShare to charge other devices wirelessly using Galaxy S10’s battery.

Galaxy S10 (including Galaxy S10, S10+, S10e, and S10 5G) can be used as a wireless charger to share Galaxy S10 battery with other devices.

This Galaxy S10 new feature guide explains the details of Galaxy S10 wireless PowerShare feature, how to use it to charge other devices, and answers some questions you may have when using the wireless PowerShare.

Update: with Android 10 update, you can now set the battery limit for Wireless PowerShare. Please refer to this guide on how to set the battery limit for Wireless PowerShare.

Please also note, Galaxy S20, Galaxy S21, Galaxy Note 10, and Galaxy Note 20 all support Wireless PowerShare. So this guide also applies to all these phones.

What is Galaxy S10 wireless PowerShare?

Wireless charging is not new. Samsung added it as a standard feature since Galaxy S6.

But using the phone as a wireless charger to share the phone battery with other devices is still new.

Huawei named this feature as wireless reverse charging and introduced it in Mate 20 Pro (in 2018) and P30 Pro. Samsung introduced this feature in Galaxy S10 (all 4 models) and named it as wireless PowerShare.

Galaxy S10 wireless PowerShare lets you share the battery juice of Galaxy S1o with other devices that support Qi wireless charging.

Technically, you can still use Galaxy S10 as usual when you share the battery with other devices.

You can even use wireless PowerShare when you are charging Galaxy S10 battery through a USB cable.  For example, you may have only one charger, but you need to charge both the phone and a Galaxy Watch.  In this case, you can connect the wall charger to charge the Galaxy S10 battery. At the same time,  you can use wireless PowerShare to charge the watch.

In a nutshell, Galaxy S10 wireless PowerShare adds a Qi wireless charger on the back of Galaxy S10. And the charger can use Galaxy S10 battery to charge other devices wirelessly.

Limitations of Galaxy S10 wireless PowerShare

Wireless PowerShare is very convenient, and it works with any devices that support Qi wireless charging.

FYI, most recent mobile devices including iPhone support Qi wireless charging. All Samsung gadgets with wireless charging support Qi wireless.

But wireless PowerShare has some limitations including:

  • Charging speed is slow. There is no fast charging. The maximum charging capacity is 5W. The actual charging speed is substantially lower than this. So, Galaxy S10 wireless PowerShare is mainly designed for accessories like Galaxy Buds, Galaxy Watch. It may be a temporal solution of sharing the battery with other phones. If the other phone also has a USB C port,  you can charge it faster by directly connecting Galaxy S10 to that phone with a USB-C to USB-C cable.
  • You may have to remove the covers or cases for Galaxy

How to use the new fingerprint reader to unlock Galaxy S10, Note 10, S20, Note 20, S21, and S22?

simon · 4 Comments

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+.

Galaxy Note 10 and Galaxy S20 also used identical in-display ultrasonic fingerprint reader.

With the removal of the 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+, Note 10, Note 10+, S20, S20+, S20 Ultra, Note 20 Ultra, s21, S21+, S21 Ultra, S22, S22+, and S22 Ultra.

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, an 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.

You may check this guide to understand the limitations of using the fingerprint reader to unlock Galaxy S10, S20, S21, and S22.

Top 10 disappointing or missing features of Galaxy S10

simon · Leave a Comment

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 we also noticed some missing features of Galaxy S10.

Galaxy S10 (all 4 models) 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. Iris scanner is gone: the most disappointing and missing feature of Galaxy S10

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 from Galaxy S10. You have to use your face (face recognition) or fingerprint reader to unlock Galaxy S10 if you do not want to type the PIN/password.

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 the iris scanner? Here is the Galaxy S1o layout.

Also, if you do not like the cutout (hole) for the front camera, you can use Galaxy S10 virtual bezel to hide the cutout.

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

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 Galaxy S10 camera app 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.

Top 10 new features of Galaxy S10

simon · 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 the 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”.

If you are not a fan of the punched hole, … Read the rest

This post explains what the Galaxy S10 Guides community does and how the Galaxy S9 guides are organized.

What does the Galaxy S10 Guides community do?

Galaxy S10 guides @GadgetGuideOnline is an online community for Galaxy S10 owners and by Galaxy S10 owners.

It is an owner-help-owner community for owners of Galaxy S10, Galaxy S10+, and Galaxy S10e. Galaxy S10 5G will be also covered.

For many Galaxy S10 owners, access to the “official” support can be:

  • Inconvenient. There may be very limited Samsung support centers in some regions. You do not want to drive a few hours to the support center, wait a few hours in the queue if you can get the answer or solution through a community like Galaxy S10 Guides here. Also, most support centers only open in office hours when you may have to work.
  • Ineffective. In the support centers, the standard procedures have to be followed. Very often, you have to reset the phone and have to wait a long time.
  • Costy. If your Galaxy S10 is out of warranty (e.g., you bought it from other regions), the cost of the visit to the support center can be quite expensive.
  • Inadequate. In most regions, the support for your Galaxy S10, S10+, S1oe, and S10 5G is limited to hardware and pre-installed apps.

Of course, for hardware related issues, you have to visit the local service center because they have all the tools software to test the hardware.

But for software related issues or feature related questions, you can find the solution or answer without wasting time in the service center.
