I give importants for the internal memory capacity. It has 64 Gb internal storage space. Its amazing to get a mobile phone at this price. The sound quality is excellent. Vivo V5s has 4GB ram. I was using a Samsung dual core mobile phone. It doesn’t supports 4G network. Vivo V5s supports both 4G and 3G networks. The resolution also very good. The design is very beautiful and good looking. I am very happy with Vivo V5s. I like it verymuch.
