    Verdict

    The Vivo V21 5G (8GB + 128GB) is an ultra-slim, mid-range smartphone with a 6.44-inch 90Hz AMOLED display and a MediaTek Dimensity 800U processor, notable for its exceptional 44MP selfie camera featuring Optical Image Stabilization (OIS) and dual LED flash, making it ideal for vlogging and night portraits. Key specs include a versatile 64MP OIS triple rear camera setup, 8GB RAM (expandable via virtual RAM), and a 4000mAh battery with 33W FlashCharge support. Major pros are its excellent, OIS-stabilized front and main cameras and sleek, lightweight design. Potential cons include the lack of an official IP water resistance rating, no 3.5mm headphone jack, a single mono speaker, and a processor that can struggle with demanding 3D games compared to other phones in a similar price bracket.

    What customers like about vivo V21 5G (8GB + 128GB)?

    • Exceptional 44MP front/selfie camera with OIS (Optical Image Stabilization), autofocus, and dual LED flashes, making it ideal for vlogging and sharp stills.
    • Sleek, stylish, ultra-slim design (around 7.3mm thick) with a premium-feel matte finish that resists fingerprints.
    • Vibrant 6.44-inch AMOLED display with a 90Hz refresh rate and HDR10+ support, providing a punchy and smooth viewing experience.
    • Solid everyday performance for general tasks, supported by an 8GB RAM and the MediaTek Dimensity 800U processor.
    • Good battery life (4,000mAh) that can last a full day or even two with light use, and fast 33W charging support.
    • Generous base memory configuration (8GB/128GB) which is expandable via a microSD card slot.
    • Includes an in-display fingerprint sensor, a feature often found in more expensive phones.
    • Funtouch OS 11 (based on Android 11/12) is described as lightweight and smooth compared to previous versions.

    What customers dislike about vivo V21 5G (8GB + 128GB)?

    • The MediaTek Dimensity 800U processor is considered mid-powered for the price point and struggles with high-end gaming or resource-intensive tasks, with performance lagging behind competitors.
    • The main rear camera performance (64MP) is inconsistent and can be mediocre, sometimes producing muted colors, artifacts, or struggling in low light, especially compared to the excellent front camera.
    • Lack of expected features in its price range such as IP-rated water resistance, stereo speakers, a 3.5mm headphone jack, or wireless charging.
    • The ultra-wide and macro cameras are generally disappointing, with the 2MP macro lens considered nearly pointless by some reviewers.
    • The design includes a 'water drop' notch instead of a more modern hole-punch cutout, and the plastic build feels less premium than some rivals.
    • The single bottom-firing speaker is easy to cover up and does not get very loud.
    • Some users reported issues with camera software updates causing lag in video recording or poor white balance in sun exposure.
