amazon OPPO A91 reviews
The modernity is thus brought by the OPPO A91, which boasts a minimal 127g weight reduction in terms of battery capacity from OPPO A9, its predecessor. While the body size of the A91 is 160.2mmx73.3mmx7.9mm, respectively, 1.2mm thinner compared to the A9.
Thus, OPPO A91 has turned into inheriting the design sophistication of A9. The device still manages to be ergonomically designed, though with ideal thinness compared to smartphones on the market today.
The reverse side of OPPO A91 is a glass imitation plastic finish, a well-suited choice more than above $280. This rear also boasts the same color-changing effect as many mid-range smartphones today, very pretty yet not quite impressive enough.
There is the minimal notch-shaped screen in front of OPPO A91 fitting quite well with a lot of apps and games nowadays having solutions on how to optimize their apps for such screen types, thus the notch will not be much of a hassle when it comes to the user’s general experience. The commendable point is OPPO A91 has super-sensitive fingerprint scanning technology 3.0 under the screen, which provides very fast capabilities for unlocking.
The screen of OPPO A91 has a 6.4-inches AMOLED display, Full HD + (1080 x 2400 pixels) with an aspect ratio of 20: 9, which makes the display sharper. Furthermore, the phone has eye protection mode using the new technology for DC dimming 2.0.
Powerful performance.
In addition to that, the unit housed the two built-in game optimization tools, HyperBoost 2.0 Plus, and GameBoost 2.0. A user can noticeably feel differences in touch response speed, network stability, and an increase in their game’s frame rates when using. Currently, the performance of OPPO A91 is amazing for more than $280.
OPPO A91 has camera systems diverse.
OPPO A91 is among the very few mid-range models boasting clusters of 4 sensors up to 48MP. Thanks to HDR technology, OPPO A91 can capture its night shots with high resolution, balanced light, and pretty good detail. The camera has the following specifications for its four cameras:
– 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 (takes roughly close images with high detail).
– 2MP depth sensor.
With all that, OPPO A91 is capable of portrait photography that is more than acceptable, both with light from behind and within the dark. There are loads of detail and realism created in the final image.
A hair-and-chin tracking system with AI beautification is simultaneously observed on the OPPO A91 camera. The new algorithm works upon 137 analysis points on the captured human face and can, therefore, automatically determine gender and age, thus allowing for optimization that achieves a smooth and natural look on skin. As far as portrait lovers are concerned, 16MP front, rear, and video cameras offer support to this feature.
User interface with smart features, massive battery
ColorOS is an interface with a flair for China and earned its praise across the world, thanks to its convenience. On OPPO A91, ColorOS 6.1 is customized on Android 9.0 Pie, which presents rather flattering menus, multiple smart features, and an enhancement that helps the performance.
The OPPO A91’s battery comes with a capacity of 4230mAh and is sufficient for fulfilling the user’s day-to-day use. The phone also supports VOOC 3.0 fast charging technology, which allows users to charge the large battery in just 1 hour.
It is a charging solution packed with VOOC 3.0 fast-charging technology by OPPO that maintains a consistent voltage and increases current, improving charging speed while delivering a safe experience for gaming sessions, so one would not want to kill the game if the juice is about to run out.
Software Plus User Experience
The A91 runs on ColorOS 6.1, which is based on Android 9.0 Pie, out of the box. While Android 9.0 was slightly outdated even during the A91’s launch, OPPO’s ColorOS incorporates its own set of features and customizations aimed at augmenting the overall user experience. OPPO has, however, released updates starting from the launch, including an upgrade to ColorOS 7, being based on Android 10, which gives a refined and modern experience.
ColorOS 6.1 and ColorOS 7 Feature Highlights:
Visual Design- ColorOS 6.1 offers a clean, minimalist design with a focus on smooth animations and easy navigation. ColorOS 7 brings refinements with an even cleaner appearance, better iconography, and a more developed system-wide dark mode. These visual updates are subtle yet do their bit to present a more up-to-date feel to the system.
Customization- OPPO gives an extensive amount of customization possibilities in ColorOS, permitting users to change everything from icon styles to home screen layout to system theme to the system font. The Theme Store offers various themes, wallpapers, and icon packs for the user to further customize his or her device.
Gesture and Navigation: ColorOS retains the good old navigation buttons alongside gesture-based navigation. The gesture controls are intuitive and fast, making app transitions feel smooth and immersive. Users can jump in and out whichever navigation they prefer, which adds flexibility to their experience.
Game Space: For the gaming freaks, A91 has OPPO’s Game Space that optimizes performance and minimizes distractions at gaming times. Game Space blocks notifications, increases graphics, and allows you to monitor real-time system performance metrics, giving you a more concentrated experience only for games.
Smart Sidebar: Smart Sidebar-a great feature that quickly gives you access to the most commonly used applications and tools. It can be accessed by swiping in from the side of the screen-easy multitasking or switching from one app to another without going to the home screen.
Security Features: ColorOS has a lot of security features including an app locker, private safe, and also the mentioned in-display fingerprint scanner. An app lock lets you lock particular applications using a password or fingerprint. A private safe is a secure place on your device where you can put sensitive files, encrypting them.
However, ColorOS has some downsides, despite all the features and customization options. The skin is alien from stock Android and at the same time purists who are after the really vanilla Android might frown at such an OS. It can be a little heavy-handed in its management of battery life, aggressively closing background applications to save power, which sometimes leads to missed notifications or problems multitasking.
Audio and Multimedia Experience.
The audio experience of the OPPO A91 is mixed. It has a single bottom-firing speaker, which is decent for sound quality but lacks the depth and richness of dual-speaker setups found on some POC competitors. This speaker would suffice for casual media consumption, such as watching YouTube videos or hearing music in a quieter environment, but it would be useless in noisy settings or when playing anything with a heavy bass.
Thus, having the 3.5mm jack is a big plus for those users who still want to use their wired headphones. The output through the headphone jack is good-a clear mids and highs, with respect to bass leaving a little to be desired. Users might want to pair this with good headphones or external speakers for a wholly entertaining audio experience.
The A91 is also compatible with Bluetooth 4.2 for accessing audio wirelessly, but it does not support newer codecs such as aptX or LDAC, technologies which would have improved the sound quality when connected with Bluetooth headphones. Indeed, the Bluetooth connection is fairly stable and reliable; nevertheless, audiophiles would find the lack of advanced codec support constraining.
For video playback, the AMOLED display of OPPO A91 does exceptionally well. It is really a pleasure to watch a movie or a TV series where the colors are bright and deep blacks are striking. The phone would support Full HD playback on streaming platforms like Netflix and YouTube with a very sharp and enjoyable viewing experience. The wide color distribution of the display combined with reasonable brightness levels ensures that the content looks well both indoors and outdoors.
Competitors and Alternatives
There is a stiff competition in the mid-range smartphone segment opposing the A91 from various manufacturers. Some of the best competitors include:
Xiaomi Redmi Note 9 Pro: The Redmi Note 9 Pro sports a largely similar performance as compared to the A91, with a slightly larger battery and more rugged build. A 48MP quad-camera setup along with a 6.67-inch mammoth display adorn this smartphone. However, from an aesthetic and screen quality perspective, the AMOLED display and slimmest design of this OPPO device shall cater to the whims of the population.
Samsung Galaxy A51: Another strong competitor is the Galaxy A51, equipped with a Super AMOLED display, a quad-camera setup, and Samsung’s One UI, applauded for its ease of use. Reputation and software support are added assets for the A51. But when it comes to value for an affordable yet feature-filled alternative, the A91 seems to a better bet.
Realme 6 Pro: Realme, a sub-brand of OPPO, deals in the Realme 6 Pro, which comes with a higher refresh rate display (90Hz), a very strong Snapdragon 720G processor, and an all-around camera. This particular device has offered smooth transitions, particularly in gaming, but actually, users might still depend more on the AMOLED screen on the A91 for color accuracy and contrast.
Vivo V17: Alternatively, the Vivo V17 also offers an AMOLED display, a quad-camera setup, and a bunch of camera features such as Super Night Mode and Ultra Stable Video. It also has a more refined software experience with FunTouch OS, which in certain cases is preferred over ColorOS. Yet others might find strong appeal in the slim design and fast charging of the OPPO A91.
Ultimately, the above options are subjective and depend on what you value most in deciding a smartphone: display quality, good camera performance, the software experience, or a good design. The OPPO A91 has a well-rounded mix, but preference will always lead to which phone among these will suit anyone best.
Pros and Cons
Pros:
Stylish and Lightweight Build: Holding and using an OPPO A91 is a pleasurable experience because of its slight build and lightweight design. The gradient finishing on the back adds unique style.
Impressive AMOLED Display: The 6.4-Inch AMOLED is the real deal here, offering rich colors, deep blacks, and outstanding contrast for media content consumption.
VOOC Fast Charge: With a very fast charging mechanism like VOOC 3.0, this phone gets charged in no time, putting less time for recharging and more time in your hands.
Versatility of the Camera Setup: The quad-camera system gives freedom to users to capture all types of shots, from wide-angle landscapes to close-up macros.
In-display Fingerprint Sensor: The optical in-display fingerprint sensor is quick and reliable, adding to the modern look of the device.
Expandable Storage: With 128GB of internal storage, this option for expandable storage via microSD provides ample space for apps, media, and files.
Good Battery Life: The 4,025mAh battery ensures the phone stands a moderate day’s use while fast charging helps top it up quickly whenever needed.
Cons:
Old Software: The A91 was launched on Android 9.0 Pie, which was outdated even then. Some users might prefer a new software experience, but the phone has been updated since.
No NFC: The absence of NFC functionality hampers mobile payments and other NFC-oriented services via the phone, which might pose a disadvantage to some users.
Single Speaker: The single, bottom-firing speaker is good, but it does lack almost any of the depth and richness that competitive phones with a dual-speaker layout offer.
No 4K Video: Basically, while 1080p is an acceptable standard for low-end smartphones within this price range, it would leave some customers high and dry who are expecting something more in the video department.
Plastic Body: The plastic build is great, however, some customers might like the more expensive feel of glass or metal.
Conclusion
A good blend of design, performance, and features at an equally attractive price makes OPPO A91 a well-balanced mid-range smartphone. Slim and light, it is arguably one of the more transportable devices in this category; the AMOLED display presents a visual experience equally as good as some more expensive phones. The versatile quad-camera configuration can take a variety of photos, well-suited for users wishing for more flexibility in their mobile photography, making this phone qualify for casual photographers.
Quite a few plus points: fast charging, reliable in-display fingerprint sensor, and expandable storage. Still, the A91 has its limitations, and the software that was old when launched, lack of NFC, and no 4K video recording may draw some users away. The single speaker and plastic build aren’t exactly shortcomings but rather restrictions that some users may keep in mind while comparing OPPO A91 with the other smartphones in the same price category.
