OPPO A77s comes as an attractive option for users who want a different experience from the previous A7 series line. This is because the A77s carries a variety of all-first features, most of which are derivatives of more expensive products.
So , if sophisticated friends are interested in proposing to this device in the near future, it’s a good idea to first listen to what the advantages and disadvantages are.
Advantages of OPPO A77s
1. Luxury design with fiberglass skin
The A77s has a Sunset Orange variant with fiberglass leather material. Luxurious and comfortable when held. The texture is like lychee grains, smooth and silky to the touch, and not easily soiled by finger marks. To get such luxurious materials, OPPO carried out the coating and baking process 6 times.
As well as being sleeker, the coating is also more durable than other imitation leathers. In our opinion, OPPO has been quite successful in presenting a high-end mobile-style display on phones whose prices are much more pocket-friendly.
2. 90Hz screen
This cellphone screen is supported by a 90Hz refresh rate for smoother image movement. There is also All-Day AI Eye Comfort with a maximum brightness level of 600 nits during the day and can drop to 2 nits at night. That way, our eyes will be more comfortable looking at the screen for a long duration.
3. The camera supports Bokeh Flare Portrait
OPPO A77s is also the first member of the A7 series to have the Bokeh Flare Portrait feature. Sophisticated friends can create photos with artistic neon bokeh effects in the form of charming light balls.

4. RAM expansion up to 8GB
In addition to the default RAM of 8 GB, sophisticated friends can add more RAM up to 8 GB. So the total reaches 16 GB. Steady for multitasking.
5. Long lasting battery
The 5,000 mAh battery is very sufficient to accompany your activities all day long.
6. 33W SuperVOOC dan Charging Port Protection
33W SuperVOOC support allows charging up to 50 percent in less than 30 minutes. In addition, for the first time in the A7x Series line, OPPO has added Charging Port Protection technology. As the name implies, this feature is useful for protecting the battery charging process. For example, when the charging port is wet, the charging process cannot continue.

7. Already supported Multi-cooling System
The Multi-Cooling System is usually only available on the more expensive series of phones. Its function is to keep the temperature from getting hot so that performance remains stable when playing games or running other heavy applications. That way, you can play longer without worrying about decreasing performance.
8. Ultra-Linear Dual Speaker
OPPO A77s is equipped with Ultra-Linear Dual Speakers (dual speakers) to present audio with a better and clearer surround effect. There is also Ultra Volume support so that the sound sounds louder but still optimal, aka not broken, and 3D Dolby Atmos Ringtone.
Disadvantages of OPPO A77s
1. HD+ screen resolution only
Even though the performance of the HD + screen makes performance lighter, it must be admitted that in some conditions content will look more satisfying at Full HD + resolution.

2. The screen design still has bangs
The A77s screen still has waterdrop bangs. It would be more modern if it had a punch hole.
3. There is no ultra-wide camera
Yes, there is no ultra-wide camera. We found this lens to be quite useful for everyday use scenarios.
4. The results of the photos still need to be improved
Sometimes the photos look less than optimal, especially for indoor shooting. The selfie camera is still lacking in detail.
5. No NFC
In its price class, some competing cellphones are equipped with NFC.
Those are some of the advantages and disadvantages of OPPO A77s. This smartphone is sold at USD $222,99.
