How to use a micro SD card on Galaxy S20?

By Leave a Comment

use a micro SD card on Galaxy S20Samsung always supports the micro SD card support on all Galaxy S and Galaxy Note phones except on Galaxy S6 and Galaxy Note 5. Galaxy S20 can support a micro SD card up to 1TB.

But the support of the micro SD card on Galaxy S20 is different from that in stock Android.

This Galaxy S20 guide explains the supported micro SD card features on Galaxy S20, the requirements of using a micro SD card, how to add and manage the SD card, how to move apps to the micro SD card and how to mount and unmount the SD card on Galaxy S20, and how to choose an SD card for Galaxy S20.

In this guide, Galaxy S20 refers to Galaxy S20, Galaxy S20+, and Galaxy S20 Ultra.

Does Galaxy S20 support adoptable storage so that I can use the micro SD card as internal storage?

No, Galaxy S20 does not support the adoptable storage. But Galaxy S20 does support moving apps to the micro SD card.

Since Android Marshmallow (Android 6), Google introduced the adoptable storage to let you use the micro SD card as internal storage. It essentially increases the internal storage capacity at a far lower price.

Of course, due to performance limitations of the micro SD card, most flagship Android phones do not support the adoptable storage. Some, for example, Google Pixel phones, do not have a micro SD card slot at all. The adoptable storage support can be found in many middle-range and budget Android phones.

The other option is to use the micro SD card as portable storage, where you can save your own files, for example, your music or media collections. Apps can also request to access the portable storage to download and save large files.  The “flagship” (usually means expensive and overpriced) Android phones with a micro SD card support, often only support the portable storage.

Unlike other Android vendors, Samsung chose a proprietory way to support micro SD card. It is somewhere between adoptable storage and portable storage.

  • You cannot format the micro SD card as the internal storage on Galaxy S20.
  • But you can move most apps to the micro SD card if you want.

Actually, this is a better implementation than the adoptable or portable storage, because

  • The micro SD card is portable.  You can share the media files on the SD card on any

How to use and manage SIM card on Galaxy S20?

How to use and manage SIM card on Galaxy S20?You need a SIM card on Galaxy S20 if you want to connect the phone to a mobile network for voice,  or data, or both.

Of course, you can use Galaxy S20 without a SIM card (you can use WiFi/Bluetooth/USB for connections). But it does not make sense to buy a Galaxy S20 if you plan to use it without a SIM card. You can get a WiFi-only tablet at a far cheaper price.

This Galaxy S20 guide explains the size of the SIM card on Gallaxy S20, possible configuration for the SIM card tray, how to use the SIM card on Galaxy S20 with or without a micro SD card,  and how to use two SIM cards and eSIM on Galaxy S20.

The detailed explanation of eSIM support on Galaxy S20 can be found here.

What is the SIM card size on Galaxy S20?

Like most other phones released in recent years, Galaxy S20, S20+, and S20 Ultra all use nano-SIM cards only.

A nano-SIM card is the smallest one among the 4 possible SIM card sizes for mobile phones:

  • Standard.
  • Mini.
  • Micro.
  • Nano.

Most carriers now issue 3-in-1 SIM cards (as shown below).  In this case, you can detach the largest part as a mini-SIM. Then you can get a micro-SIM card from the mini-SIM. A nano-SIM card can be detached from the micro SIM card.

You should keep the “waste” because they can be used as an adapter for micro-SIM (from nano-SIM card), or mini-SIM adapter (from micro-SIM). Some old tablets and MiFi (mobile router) may still require a larger SIM card.

If you are using a phone bought within the last 10 years, very likely,  the phone is using a micro SIM card or a nano-SIM card.

It is possible (and simple) to trim a nano-SIM card from a micro-SIM card. But it is recommended to do it in the handphone shop using a properly-sized clipper. Do not use scissors.

Here is a list of some popular phones that use nano-SIM card already. If you want to migrate to Galaxy S20 from these phones, you can keep using the existing SIM card.

  • Samsung Galaxy S6, S7, S8, S9, S10 and all their variants (e.g., S10, S10+, S10e, S9, S9+, S8,  S8+, S7, S7 Edge, S6, S6 Edge, and S6 Edge+).
  • Samsung Galaxy Note 5,  Note 7 FE, Note 8, Note 9, Note 10, Note 10+,

Everything about eSIM support and use eSIM on Galaxy S20

By 2 Comments

Galaxy S20 eSIM support and use eSIM on Galaxy S20Galaxy S20, S20+, and S20 Ultra have eSIM support in most regions.  But your carrier may not support eSIM on Galaxy S20.

This Galaxy S20 guide explains what eSIM is, the advantages of using eSIM on Galaxy S20, how to check eSIM support on Galaxy S20, how to add eSIM Profiles on Galaxy S20, and how to use eSIM on Galaxy S20 together with physical SIM cards.

You may check this guide on how to use the SIM card tray and the physical SIM cards on Galaxy S20.

What is eSIM?

Traditionally, you need to get a SIM card from your phone company to make and receive phone calls, send and receive text messages, and use mobile data.

The SIM card is your ID. It is unique in the whole global mobile networks. The mobile operators use the SIM card to identify the company issued the card, whether this card can connect to their network or not, and what resources (mobile plan) you can use if you can connect to the network.

As the SIM card is unique, you have to get the physical card from the carrier. When you change carrier, you cannot use the old SIM card, and you have to get a new SIM card from the new carrier.

The process can be painful. Sometimes, you have to visit a physical store and queue there for one or two hours for the tiny SIM card. Or sometimes, you have to wait a few days before it is delivered to your mailbox.

It is even more painful or some frequent travellers who prefer using a local SIM card (to avoid exacerbate roaming charges). Every time, when you reach the destination airport, you have to walk around the airport to get a local SIM card. In some countries, the SIM card sold in airports is usually not good for value.

eSIM, embedded-SIM (or more officially, embedded universal integrated circuit card, eUICC), was proposed to tackle this issue (and other provisioning issues). The standard is maintained by GSMA.

In a nutshell, eSIM is embedded storage for SIM cards in your phone. You can save each SIM card info as a Profile.

And, you can save multiple Profiles on it. GSMA does not limit the maximum Profiles you can save on one device. It is only limited by the storage capacity and the size of each Profile.

But where is the power button? If you are an owner of  Galaxy Note 10  (or Note 10+), then you may find the power button (side key) is not relocated back to the right.

If you want to record an audio clip (especially in the interview mode), you probably need to know the location of the two microphones.

If you want to use NFC, use wireless charging, or use wireless PowerShare, you need to know the location of antennas and coils.

If you are new to the in-display fingerprint sensor, you need to know where to put your fingers on.

#1. The screen

About 90% of the front part of Galaxy S20 is what Samsung called “Dynamic AMOLED 2X” screen.

By Leave a Comment

Unbox Galaxy S20: items in Galaxy S20 boxOnce you unbox Galaxy S20, you need to understand the items in the Galaxy S20  box and know how to use them.

This Galaxy S20 guide illustrates the contents in Galaxy S20 box and explains to you how to use them (including the phone, wall charger, clear back cover, USB cable, USB-C headset with additional ear tips, and  SIM card tray ejection pin).

The contents (items) in Galaxy S20, S20+, and S20 Ultra are almost identical except the phone, although there are significant differences among these 3 models.

So, in this guide, Galaxy S20 refers to all of these 3 models: Galaxy S20, S20+, and S20 Ultra.

What is included in the Galaxy S20 box?

As shown in the picture below, after unboxing Galaxy S20, there are at least following 7 items in the Galaxy S20 box:

  1. The phone.
  2. Clear cover.
  3. USB-C cable.
  4. Wall charger.
  5. USB-C (AKG) headset.
  6. Additional ear tips (small and large).
  7. SIM card tray ejection pin.

Understand the contents in Galaxy S20 box

Now, let’s go through the items in the Galaxy S20 box one by one.

#1. The phone: Galaxy S20, S20+, or Galaxy S20 Ultra

Of course, this is the main and the most expensive item in the box. Others are just “accessories”.

In many regions, Samsung does not offer a one-for-one exchange. If you find any problems after leaving the counter, you need to claim the warranty.

So, you should check the phone on the spot. If there are any issues, you can choose not to accept the item.

Because of the ultrasonic in-display fingerprint reader which is one of the worst “innovations”, some tempered glass screen protectors will not work with the fingerprint sensor.

In most regions, Samsung pasted (pre-installed) a plastic screen protector on the screen already. The quality of the screen protector is actually quite good. And most importantly, it works nicely with the in-display fingerprint reader.

If you need a screen protector, you should not remove it before you get a new one. If you try to re-apply the screen protector, very likely, you will get many bubbles.
