The “Shockproof Crystal Clear | 360 Degree Protection | Protective Design” back cover case for the Vivo Y20 typically offers the following key features:
🛡️ Top Protective Features
-
Shock-Absorbent Bumper: The edges are usually made of Soft TPU (Thermoplastic Polyurethane), often featuring reinforced corners or “airbag” technology to absorb the force of accidental drops and impacts.
-
360 Degree Protection: This indicates comprehensive coverage. The case wraps securely around all sides of the Vivo Y20.
-
Raised Edges (Bezels): The case has raised lips around the camera module and the front screen to lift them off flat surfaces, preventing scratches when the phone is placed down.
-
Durable Material: The back is usually a hard, clear PC (Polycarbonate) or Acrylic for maximum protection against scratches, while the bumper remains flexible for shock absorption (a dual-material design).
✨ Clarity and Design
-
Crystal Clear Transparency: The back panel is designed to be highly transparent, allowing you to showcase the original color and design of your Vivo Y20 without obstruction.
-
Anti-Yellowing Technology: Many high-quality clear cases are treated to resist UV degradation and yellowing over time, maintaining their crystal-clear look.
-
Sleek & Lightweight Profile: Despite its protective features, the case is usually engineered to be slim and lightweight, avoiding excessive bulk.
-
Micro-Dot Pattern: Some cases feature an almost invisible micro-dot pattern on the inner back panel to prevent the case from sticking to the phone’s surface, which avoids unsightly “wet” marks or bubbles.
⚙️ Functionality
-
Precise Cutouts: The case is specifically molded for the Vivo Y20, ensuring full, unobstructed access to all ports (charging, headphone jack), speakers, and the fingerprint sensor (if on the side).
-
Responsive Buttons: The volume and power buttons are covered by the bumper but are designed to remain tactile and easy to press.
-
Wireless Charging Compatibility: This type of case is typically thin enough to support wireless charging if your Vivo Y20 model supports that feature.
Overall, it’s a popular choice for users who want maximum protection without hiding their phone’s aesthetics.
