Detailed Review of Oppo A15 Phone
1. Design and Display of Oppo A15
First off, let's talk aesthetics. Oppo A15 sports a glossy plastic finish that reflects light beautifully but is prone to fingerprint smudges. Despite its large size with a 6.5-inch display, it's quite lightweight (around 175 grams) and feels really comfortable to hold. If you have smaller hands, you won't find this phone uncomfortable or unwieldy to use. The overall interface of Oppo A15 is genuinely sleek, solid, and devoid of any 'cheap' vibes.
At the back, you'll find a square-rounded triple camera setup placed at the top left corner. Oppo A15 also features a rear fingerprint scanner and face recognition unlock. Both of these functions work quite well.
2. Visual Display and Audio
Oppo A15 offers you a large and bright display with a waterdrop-style LCD screen, HD+ resolution, and 480 nits brightness. The display quality is fairly decent for its segment. Additionally, the device also comes with automatic brightness adjustment feature.

The screen provides a relatively great viewing experience, sometimes it's easy to forget that it's not the screen of a more expensive device; HD videos look crisp and sharp. Although colors aren't as vibrant as you'd get from a higher-end screen. The built-in speakers are a bit underwhelming - decent quality and you're accustomed to it, but it lacks depth and bass, resulting in a somewhat 'tinny' listening experience. However, this is understandable for budget devices.
3. Camera
At this price point, OPPO has done quite well in ensuring your photography needs are met with the triple rear camera setup featuring a 13MP primary lens, 2MP macro lens, and 2MP depth sensor. The front selfie camera is 5MP and presented in a waterdrop-style notch. Along with it are some included features like Portrait mode, Night mode, Panorama, and HDR. While it may lack the extensive photography features found on pricier devices, it still covers the basics. Video capabilities are also quite basic, allowing you to shoot at 1080p and 30fps.

4. Configuration and Performance
OPPO A15 is equipped with a MediaTek Helio P35 processor, paired with 3GB of RAM and 32GB of built-in storage. If you need more than 32GB, the microSD card slot on the device can expand it up to 256GB.
So, Oppo A15 offers users a basic-level smartphone with decent performance but nothing groundbreaking. It will suit tasks like work and light entertainment.

Oppo A15 features a 4,230mAh battery, which is large enough to last you through a full day of use. However, the device's charging speed is quite slow as it only comes with a standard 10W charger.
