amazon OPPO A91 reviews
Modern design
With less battery capacity on OPPO A9 (predecessor), OPPO A91 has reduced the weight to only 127g. While the body size of the A91 is 160.2mmx73.3mmx7.9mm, respectively, 1.2mm thinner than the A9.
Thus, OPPO A91 continues to inherit the design sophistication of A9. Besides, the device still ensures a good grip when holding, despite possessing ideal thinness compared to smartphones on the market today.
The back of OPPO A91 is finished from glass imitation plastic, an option suitable for more than $280. This back also uses the same color-changing effect as many mid-range smartphones today, quite beautiful but not impressive enough.
The front of OPPO A91 is a minimalistic notch-shaped screen that looks quite fit. In addition, many applications and games now have solutions for this type of screen optimization. Therefore, the notch will not cause much trouble to affect the user’s daily experience. The commendable point is that OPPO A91 supports super-sensitive fingerprint scanning technology 3.0 under the screen, providing very fast unlocking capabilities.
The screen of OPPO A91 uses a 6.4-inch AMOLED panel, Full HD + (1080 x 2400 pixels) with an aspect ratio of 20: 9 for a sharp display. In addition, the phone is also equipped with eye protection mode with DC dimming 2.0 technology.
Powerful performance
OPPO A91 is powered by the octa-core 12nm Helio P70 processor (the current P-series flagship chip from MediaTek), which combines 8G + 128G memory. Since today’s mobile games are almost impossible, bringing the same performance on high-end smartphones is difficult for OPPO A91.
Not stopping there, the device also has two built-in game optimization tools, HyperBoost 2.0 Plus and GameBoost 2.0. Users can feel significant improvements in touch response speed, network stability, and game frame rate when using. At this point, the performance of OPPO A91 is great compared to the price of more than $280.
OPPO A91 owns a diverse Camera system
OPPO A91 is one of the few mid-range models with a cluster of 4 sensors up to 48MP. With the support of HDR technology, OPPO A91 can fully capture night photos with high resolution, harmonious light, and pretty good details. The phone’s four cameras have the following parameters, respectively:
– 48MP main sensor (combining 4 pixels into one large pixel, 5x zoom).
– 8MP ultra-wide-angle sensor with 119-degree viewing angle.
– 2MP macro sensor (take close-ups with high detail).
– 2MP depth sensor.
OPPO A91 gives very good portrait photography with the above equipment, whether in backlit or night mode. The image produced is full of details and realistic lighting.
At the same time, the camera of OPPO A91 also has an AI beautification function. The new algorithm is based on 137 analysis points on the captured human face, which can automatically determine gender and age, thereby automatically optimizing, making the subject’s skin look smooth and natural. The good news for those who love portrait photography is that the front (16MP), rear, and video cameras support this feature.
A smart user interface, large battery capacity
ColorOS is inherently an interface that resonates in China and won many compliments from world technology fans because of its convenience. On OPPO A91, ColorOS 6.1 is customized on Android 9.0 Pie, which brings a rather flattering menu, many smart features and helps to improve performance.
OPPO A91 is equipped with a battery with a capacity of 4230mAh, large enough to meet the user’s daily use needs. In addition, the phone also supports VOOC 3.0 fast charging technology, which helps users fully charge the large battery in just 1 hour.
OPPO’s VOOC 3.0 fast-charging technology uses a solution to maintain the same voltage and increase current, improves charging speed, and supports safe charging while playing, suitable for gamers not wanting to abort the match if the phone is about to run out of battery.
