How to use Galaxy S20 face recognition (face unlock)?

By Leave a Comment

use Galaxy S20 face recognition (face unlock)You can use Galaxy S20 face recognition to unlock the phone (face unlock) by just looking at the phone.

Because the in-display ultrasound fingerprint reader on Galaxy S20 ( and S10) is hard to use and is slow, many Galaxy S20 owners have to use face recognition to unlock the phone and find that face recognition (face unlock) is faster than the fingerprint.

This Galaxy S20 guide explains what Galaxy S20 face recognition is, how to use and manage face recognition to unlock Galaxy S20, how to register your facial features for face unlock, and limitations of Galaxy S20 face recognition.

Galaxy S20 face recognition (face unlock) works identically on Galaxy S20, S20+, and S20 Ultra. So this guide applies to all of these three models.

What is Galaxy S20 face recognition (face unlock)?

In addition to using a PIN or password, you can use your biometrics to unlock Galaxy S20 (and other Android phones as well).

Galaxy S20 implements two biometrics features:

  1. Fingerprint.
  2. Facial recognition.

Please note, Samsung stopped using (the most promising) iris scanner since Galaxy S10. You can find the iris scanner on Galaxy S8, S9, Note 8 and Note 9.

So, you can use your fingerprint and face to unlock Galaxy S20 if you want. By default, both fingerprint and facial recognition is not enabled.

Android included face unlock since Android 4.0 (Icecream Sandwich). Of course, it is less accurate than a fingerprint reader. Prior to Android Nougat (Android 7.0), it is easy to fool the phone with a photo.

In recent releases, Android has greatly improved facial recognition. It is fast enough so that you do not need to wait too long. It is accurate enough so that you cannot cheat it with a photo.

Of course, the face unlock on all Android phones is still considered as “less” secure than the fingerprint.

When Samsung ditched the iris scanner (and the intelligent scan), Samsung did NOT add an IR camera. So, on Galaxy S20, face unlock purely relies on the selfie camera. It is NOT comparable to Apple Face ID.

You may consider the Galaxy S20 facial recognition if you need an alternative to the inferior in-display fingerprint scanner.

Why is Galaxy S20 face recognition (face unlock) important?

As mentioned, in most Android phones, the traditional fingerprint reader works very well. You just put your finger on the reader, and it can wake … Read the rest

How to unlock Galaxy S20 to Home screen directly (without swiping on Galaxy S20 lock screen) with face recognition?

Many Galaxy S20 owners want to reach the Home screen without swiping on Galaxy S20  lock screen when using face recognition to unlock Galaxy S20.

As Galaxy S20 uses the inferior and inconvenient in-display fingerprint sensor,  most  Galaxy S20 owners find the face recognition (face unlock) is the most convenient way to unlock Galaxy S20 quickly.

This Galaxy S20 guide shows you how to unlock Galaxy S20 to Home screen directly without swiping on Galaxy S20 lock screen when using face recognition on Galaxy S20.

The face recognition on Galaxy S20, S20+, and S20 Ultra works identically. So, this guide applies to all of these 3 Galaxy S20 models although only “S20” was used in the text.

5 worst features of Galaxy S20, S20+, and S20 Ultra

By Leave a Comment

top 5 worst features of Galaxy S20, S20+, and S20 UltraGalaxy S20, S20+, and S20 Ultra will be one of the best selling flagship phones in 2020, although there are some missing features and poorly implemented features.

This Galaxy S20 guide explains the top 5 worst features of Galaxy S20, S20+, and S20 Ultra: in-display fingerprint scanner, curved screen, no headphone jack, no QC 3.0-, and the price.

In-display fingerprint scanner: the worst of the worst features of Galaxy S20

Samsung introduced the ultrasonic in-display fingerprint sensor in Galaxy S10.

It’s probably one of the worst features in S10 and S10+. Luckily, you can still choose Galaxy S10e if you need a better fingerprint reader.

The in-display fingerprint reader in most cases is less accurate, slower, and inconvenient. It is an example of meaningless innovation for smartphones.

Samsung since then added this not-ready features to all of their “flagship” smartphones to differentiate them from other Android phones (because only a few Chinese brands used similar or even worse in-display fingerprint read).

If you skip the fingerprint reader, then you have only the less secure face recognition for biometric authentications.  The default behaviour of face recognition in Galaxy S20 is that you have to swipe on the lock screen after the phone is unlocked. You need to follow this guide to disable the stay on the Lock screen.

All of the three Galaxy S20 models (Galaxy S20, S20+, and S20 Ultra) use the same in-display fingerprint sensor.

If you need a normal fingerprint reader, you should eliminate Galaxy S20 from your list.

Although Samsung claimed they improved the fingerprint sensor, for example, a larger touch area (see Galaxy S20 layout) and faster recognition, it is still inferior to most of the capacitative fingerprint readers found in many middle-range smartphones.

You will feel the pain sooner or later. Especially, in the dry winter, it is almost impossible to use the in-display fingerprint reader.

So, we consider the in-display ultrasonic fingerprint scanner is the worst of the worst features of Galaxy S20, Galaxy S20+, and S20 Ultra.

Curved screen

Samsung “invented” the curved screen in Galaxy Note Edge (Note 4 Edge) with a separated curved edge screen, which nobody likes.

Samsung is so proud of their curved screens that they want to make it a signature feature of their top-tier smartphones, although it reduces the usability of the phone.

Since Galaxy S6,  the curved screen became an option: you … Read the rest
