The design and build quality are solid, with a plastic back. The screen is large and bright, but lacks protective glass. Performance is smooth, but camera quality could be improved. Battery life is decent, with fast charging. The device has various functions and sensors, but lacks water resistance. The operating system is user-friendly, but could use more updates. Call quality is good, with stable connections. Overall, the phone offers decent value for its price. | ||
