Display and audio

It has a 6.44-inch OLED display with Full HD+ resolution (2400 x 1080 pixels), which translates to a pixel density of 408 PPI. The screen display has good brightness, contrast, color accuracy, and viewing angles. It also supports HDR10 for enhanced dynamic range and DCI-P3 color gamut for more comprehensive color coverage.

The display has some features that improve the user experience, such as a Sunlight Screen that adjusts the brightness automatically under solid sunlight, a Moonlight Screen that reduces blue light emission at night, a Dark Mode that saves battery life and reduces eye strain, and Always-on Display that shows time, date, notifications, and other information when the screen is off.

In addition, it has a single bottom-firing speaker that produces decent sound quality for its price range. Thus, it can get loud enough for casual listening, but it lacks bass and clarity at high volumes. Besides, it supports Dolby Atmos for surround sound effects when using headphones or external speakers.

Performance and battery life

Also, it has an Adreno 610 GPU for graphics processing. Hence, it can handle basic tasks such as web browsing, social media, messaging, video streaming, and casual gaming smoothly and without lag. However, it may need help with more demanding tasks such as multitasking, heavy gaming, photo editing, or video recording. Surprisingly, it has a 4000mAh battery that can last a full day of moderate usage or up to two days of light on a single charge. 

Camera and video

The OPPO A73 CPH2099 has a quad-camera setup on the back that consists:

• 16MP main camera with f/2.2 aperture;
• 2MP monochrome camera with f/2.4 aperture;
• 2MP portrait camera with f/2.4 aperture;

The primary camera can take decent photos in good lighting conditions, with accurate colors, sharp details, and balanced exposure. Nevertheless, it may suffer from noise, blur, or loss of detail in low-light situations or when zooming in.

Also, the ultra-wide camera can capture more scenery in one shot, but it may introduce distortion or chromatic aberration around the edges of the frame. Besides, it has a lower resolution and dynamic range than the primary camera. The monochrome camera can add depth and contrast to black-and-white photos, but it may only be helpful for some users.

In particular, the portrait camera can create a bokeh effect or background blur for portrait shots. Still, it may not accurately or consistently detect edges or separate the foreground from the background.

Moreover, this phone has a 16MP selfie camera with f/2.2 aperture on the front that can take good selfies in daylight or indoors with sufficient lighting. It also has an AI Beauty mode that can enhance facial features or smooth skin according to user preference. Also, it supports electronic image stabilization (EIS) that can reduce shaky footage to some extent.

Furthermore, it has some camera modes that can enhance the photography experience, such as:

• Photo. The default mode allows users to adjust settings such as flash, HDR, timer, filters, aspect ratio, etc.
• Video. It allows users to record videos with options such as Flash, EIS, filters, etc.
• Expert. The mode will enable users to manually adjust settings such as ISO, shutter speed, white balance,
• Focus mode, etc.
• Panorama. This mode lets users capture wide-angle photos by moving the phone horizontally or vertically.
• Portrait. This phone allows users to take portrait shots with a bokeh effect using either the rear or front cameras.
• Time-lapse. This mode will enable users to record videos at accelerated speed by capturing frames at longer intervals.
• Slow-motion. It reduced the rate by capturing frames at shorter intervals.
• Google Lens. Using Google’s image recognition technology, the mode lets users identify objects or information.
