Hi friends, vivio v5s mobile has a very good feature but the main default I found with this product is that the battery capacity is very low to use its full potential. The main attractive of the phone is front camera. The features are good but the money value is very high when compared to other phones. A person who loves photography the most can buy this phone. Heating of the battery while charging is also problem with this phone. Sound is excellent and it is good to hear with headphone. Body is slim and it can be hold in hand firmly. Body looks beautiful and excellent way of design.
