Entry class smartphone "OPPO A55S 5G" for 5G

The focus of OPPO A55S 5G is that it supports waterproof and dustproof properly.For the first time in the OPPO A series, it supports high -level waterproof and dustproof, equivalent to IPX8 / IP6X.In addition, the screen is 6.The advantage is that it is as large as 5 inches and supports 5G and 4G dual SIMs and ESIMs.

The color is black and green.I tried a green model.The back is a greenish milky white color reminiscent of a green porcelain pottery, soft and friendly.The logo has a small neat design, and the side is a green plating finish that matches the color on the back.

The thickness is 8.It is 2mm, and it is thinly finished as a waterproof smartphone in the 30,000 yen range.From the back to the left and right sides, it has a shape that draws an arc, and does not impair the sense of stability when holding it in your hand.

In addition to USB Type-C as an external terminal, 3.Equipped with 5mm earphone jack.Built -in monolas speaker.

Like the conventional OPPO smartphone, the screen protective film has been pasted from the time of shipment, and a clear case is included.The charger and cable are not included.

The resolution of the display is also compatible with high -speed drive with full HD + (2,400 x 1080 dots) and refresh rate 90Hz.Combined with the light and light body for the screen size, e -book applications were displayed comfortably.

The chipset adopts Quarcom's Snapdragon 480.The memory is 4GB, and it is a configuration that can be covered roughly if it is a simple application centered on SNS.As a smartphone with the same configuration, there is a 20,000 -yen Zoomi smartphone "REDMI NOTE 10 JE" sold by au and UQ Mobile.

The specifications around the communication are substantial, and mobile communication supports 5g SUB-6 frequency bands.However, millimeters are not compatible, and the band N79 used by NTT DOCOMO is not available on SUB-6.

I tried 5G communication on the UQ Mobile line, but in the new frequency band area, I checked high -speed communication that was actually approaching 500Mbps.The display of the website and the preview on the Twitter application were also crispy.

The OPPO A55S 5G for dual SIM is inserted with NANOSIM card x 2 cards, and can be used simultaneously with 5G + 4G LTE.Because ESIM is also supported, the combination of nanosim + ESIM is also OK.

Wi-Fi is Wi-Fi 5 (IEEE802).Supports up to 11ac/a/b/g/n).It is not compatible with the latest standard Wi-Fi 6.

The back camera looks three eyes, but actually has a two -eye configuration.It is a combination of 13 million pixels wide -angle cameras and 2 million pixels depth cameras.

The camera part has three circles that look like a lens, but the middle is not a camera but a logo called "AI".Is the manufacturing cost reduced by diverting the design of another model of the three -eye camera?

The camera app has standard shooting functions such as portrait, night view, and panoramas, and supports up to 5 times more digital zoom when shooting still images.Since there is no wide -angle lens, the degree of freedom to choose the angle of view is low.

Photos of the camera tend to be described as "clear and clear".It tends to look slightly faded than the real thing.

I was also worried that when I started the camera immediately after launching the camera, the blur was large and that the color was not stable in the night view mode.The sweetness of the tuning around here may be expected to be improved by the post -release update.

OPPO A55S 5G is originally 4GB of memory capacity, which is small as a smartphone for Android 11.In the app that communicates to the open, or an application that requires severe operations, you may feel a little slow in response as you use it.

In the game app, I tried "Pokemon GO", but although it was not comfortable, I was able to play.There is also a problem that display collapse occurs in the scene that switches the screen, so it is certain that it is not a smartphone for the game.

Also, when I tried a major video playback app, I was able to play YouTube, Amazon Prime Video, and Disney Plus apps smoothly with full HD resolution.

What I was particularly concerned about during the trial was that video playback was applied with the "NHK Plus" app.The drawing of the video was not in time for the audio playback, and the screen display was delayed by about 30 seconds.

The sound shift in the video playback application is reported on SNS, etc., in the entry class and middle -range class smartphone released by OPPO in the past.Except for NHK Plus, similar symptoms have been reported in "DAZN".In the OPPO's high -end model "OPPO Find X3 Pro", I have no display delay in the NHK plus app.It seems that it occurs mainly for entry models with low memory capacity.

As a countermeasure, if you enable "high performance mode" by setting the battery from the terminal settings, the symptoms will be alleviated.However, the symptoms of the screen drawing slightly jerky remained.

The battery capacity is 4000mAh a little larger.If you turn off the "high performance mode" and use the power saving mode effectively, it seems that you can use it for 2-3 days without any problems.

However, if you use an app like an NHK plus that is difficult to use unless you are in high performance mode, the battery life will be shorter.As a trial, I continued to play videos for about two and a half hours since the full charge, and when I tried using a web browser for about 30 minutes, the battery level was 54 %.Depending on the situation, if you take it out in the morning and charge it at night, it seems unlikely that the battery life will be a problem.

Charging supports up to 10W (5V/2A).Cable and charger are not included in the main unit, and it is necessary to prepare a charging environment for USB Type-C separately.

One of the weak points in OPPO A55S 5G is biological authentication.Fingerprint authentication is not installed, and only "face authentication using an in -camera" is supported.Face authentication is authenticated using only the data obtained by the in -camera.It is a type that does not use a dedicated sensor, such as Apple's FaceID, and is said to be inferior to the accuracy of authentication.

This face authentication cannot be registered with a face with a mask.You may find it somewhat inconvenient in the corona that you don't know how long it will be prolonged.However, as far as I tried, even if the photos taken on the tablet terminal showed OPPO A55S 5G with a tablet display, it was not unlocked.

If you summarize the good points of OPPO A55S 5G, it will be as follows.

On the other hand, the processing performance is also appropriate for the price.There are places where you are worried about incompatibility with some video apps.Regardless of the image quality, the camera is worrisome.

Nevertheless, in a smartphone that supports 5G and waterproofing, there is no doubt that it will be inexpensive.If the price is set in the first half of the 30,000 yen range, if you aim for the timing of selling MVNO sale, you may be able to get it in the 10,000 yen range.

The 5G is now on the way of development, especially in Tokyo's 23 wards, so high -speed communication is available in many places.It will be worth choosing this OPPO A55S 5G as a smartphone that people who want to try 5G at reasonable prices take it first.
