Detailed review of Oppo A91's features

Here's our thorough explanation of whether you should buy the Oppo A91. We thoroughly evaluated how easy it is to hold, its operability, processing performance, multi-tasking performance, and more. We also reviewed how much we recommend it when compared to other models.

Review of the product design of the Oppo A91

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

When deciding whether to buy an Oppo A91, 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 Oppo A91 around and put it away.

Ease of grasping it in your hand to carry around

The Oppo A91 is a size that can easily be held in one hand. Even when holding it along with other things such as a wallet, its size makes it difficult to drop accidentally.

Ease of carrying it around when placing it in your pocket

It doesn't feel strange even when you put the Oppo A91 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

The Oppo A91 has a size that makes it relatively easy to keep and take out. While it sometimes get caught when sticking out of the pocket, I think it is just a matter of getting used to it.

Ease of getting it in and out of your bag

The Oppo A91 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 Oppo A91 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

The Oppo A91 is a size that allows you to have a firm grip even while using it. Since your hand is kept stable, it is difficult to accidentally drop the phone, and it is very easy to use. Since the original body size is small, the phone is still easy to hold even when using a case.

The weight you feel when using the phone with one hand

The Oppo A91 is a slightly heavy smart phone so using it with one hand for a short period doesn't cause any pain, however when used for long periods continuously it can hurt your hand. If you add a case and accessories it feels even heavier. It is preferable to use the phone with two hands and a proper case.

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

When using the Oppo A91 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 Oppo A91 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 Oppo A91 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 Oppo A91 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 Oppo A91 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 Oppo A91 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 Oppo A91 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 screen of the Oppo A91 can display pictures and videos quite vividly. This makes it great for enjoying videos and games dynamically. It has a very beautiful screen.

Ease of writing sentences

The Oppo A91 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 Oppo A91 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.

It is hard to find cases where its performance is lacking from the perspective of CPU performance, and you can even say it is excessive. In addition, it has way more memory compared to normal smart phones. From the perspective of memory, I don't think you will ever feel there is not enough memory. Conversely, it is way too capable for uses such as searching the Internet and messaging.
