I am using this phone for last 3 weeks. And the performance of this phone is great. Both cameras are realy owesom in sufficient light but in low light the camera performance is okay. Display is very bright and again the sound quality is great. The 3 gb of ram is best for playing high games. The Rom of 16gb is not so good it can be come with 32gb. And battery is okay if you use the phone for full day you have to charge it twice.
The functions of camera like slow motion is great. This phone is perfect for multi tasking and there was no lag problem in this phone. The touch response of screen is great. UI is great.
But the phone is over priced. I purchased this phone from local store. If online service is not awalaible in your locality you can buy this. Vivo is best phone in offline market. Otherwise the phone is superb.
