Im use this phone I got this phone two days ago from local shop for 8000, l like it very much. Best thing is the battery backup charged it full for one and started using watched youtube video for almost one hour befour it goes 1% down on wifi with half brightness. Using vivo phone that my friend has v1. Security features are good like visitor mode. Value for money. If not using 1% battery lasted for 2 hours.
