Review of the product design of the Galaxy A21s

Rating of the ease of carrying it around and getting it in and out of bags or pockets

When deciding whether to buy an Galaxy A21s, the first important factor is its size. Smartphones are used daily, and so it is important how easily they can be carried around and pulled out of bags or pockets. This review assesses how easy it is to carry the Galaxy A21s around and put it away.

Ease of grasping it in your hand to carry around

The Galaxy A21s is easily held with one hand, and its size allows it to be firmly held. It is small enough to be held in one hand together with things like a wallet, but this may be a bit difficult for ladies with small hands.

Ease of carrying it around when placing it in your pocket

It doesn't feel strange even when you put the Galaxy A21s in a pocket. In addition, when sitting on a chair with the phone in a pocket, it can be kept comfortably as it doesn't get caught on one's clothes or body.

Ease of getting it in and out of your pocket

Sometimes taking the Galaxy A21s out of your pocket doesn't go so well as it gets caught on fabric easily. It's safe to assume that some people will find it stressful that it is difficult to take it out smoothly.

Ease of getting it in and out of your bag

The Galaxy A21s is a size that allows you to take it in and out of your bag and use it with ease. Also, since it is compact, even if your bag is small it won't get too bulky which is convenient.

Assessment of user-friendliness and ease of handling

It is important to consider the ease of using the phone in one hand. It can be said that it would be very useful if it is easier for you to send emails and instant messages or answer calls using one hand while cooking or using your computer. Here, we have reviewed the Galaxy A21s by focusing on the ease of using it in one hand and the ease of typing in letters.

Ease of grasping the phone in one hand

To many people, the Galaxy A21s is of a size which allows it to be operated with one hand. Still, for people with small hands, it may be a bit difficult to do so. It becomes slightly larger when a case is added, and depending on the person, I think this may make it slightly harder to operate with one hand.

The weight you feel when using the phone with one hand

The Galaxy A21s feels too heavy to operate with one hand, so the device wouldn't be a good choice even if you are just going to use it for a short period of time. We suggest that you hold it tightly with both hands as it may hurt your hands if you use it with just one hand for an extended period of time.

Ease of pushing the upper button on the screen using one hand

When using the Galaxy A21s with just one hand, it is quite difficult to press the button on the screen edge. We suggest you operate the device with both your hands rather than pushing your luck with just one hand.

The size of the buttons on the App

The buttons on the Galaxy A21s are displayed quite large. Because of this, it is difficult to press something by mistake and it feels very easy to use. Even with games that use small buttons, it's difficult to press something by mistake making it very easy to play.

Ease of typing in letters using the flick function

Keys on the Galaxy A21s can be pressed even when held with one hand, but your grip may weaken when trying to flick the buttons at the edges. As a result, it may become unstable in the hand when flicking quickly, but it won't be easy to drop as long as you are careful.

Ease of typing in letters using the keybord funtion

If you aren't being careful it is really easy to mistype when using the Galaxy A21s with two hands since the buttons are so small. In addition, typing at high speeds is pretty difficult and I can't say its very suited for it.

Assessment of whether it is suitable for standard use

Assessment of whether it is suitable for standard use

For people who use their smartphone on a daily basis, high performance is a rather important factor. When the performance is not good enough, then, for example, applications don't work as they should or the screen is difficult to see, and this causes stress. This review looks at whether the performance of the Galaxy A21s is suitable for making phone calls, messaging, or using SNS.

The size of the letters and the ease of operation

Because the display of the Galaxy A21s is much larger than ordinary phones, characters are displayed quite large. Therefore, it is suitable for reading long bodies of text and exchanging long messages while doing research.

Ease of reading sentences

Since the Galaxy A21s displays characters smoothly, it can display them beautifully. Even when viewing small characters, the jaggedness of the character outline is not at a level seen during normal viewing and is displayed very naturally. Because of this, it is difficult for your eyes to become tired and make the phone suitable for reading long bodies of text.

The beauty of the overal screen

The Galaxy A21s can display photos and videos beautifully. While people with good eyes can see jagged outlines when they look at the display up close, it is not really something of concern.

Ease of writing sentences

The Galaxy A21s has enough screen space even when typing and the screen is hidden by the on screen keyboard. Because the sentences being typed can be seen clearly, the phone's screen size makes it suitable for typing and editing large bodies of text such as office documents.

Does it have sufficient performance to make calls and send emails?

Whether it be a phone call, mail, or during a chat, the Galaxy A21s provides smooth performance. Even when using the phone in demanding situations, you can use the phone comfortably since there will usually be no lag.

Does it have sufficient performance to search for things and using Social Networks?

If it is just SNS such as Facebook and Instagram, and some internet searches, the performance is enough. As a result, you will hardly ever find yourself frustrated or annoyed when using this phone.

Does it have sufficient performance to do other tasks while searching for things and using Social Networks?

Even if you start multiple apps at the same time or switch between apps frequently, you will have smooth performance. It can be said that the performance is more than enough if you just do research and SNS.
