Use the phone once and you will feel like cursing the brand time and again. Vivo U20 is one of the worst releases from the company. No one has expected the handset to be good for nothing. It has got Qualcomm Snapdragon 675. I do feel that companies with great reputation must not give chance to any user to accuse them for performance reasons. It is such a shame for them. When people trust a brand, it becomes their duty to take care of every expectation of every single user. Even if it is not possible, the company still can make it work lag free at least. And sadly the company could not even do so. People hail the company for more than one reason. And even the company strives a great deal to bring distinction. But this device, Vivo U20, has dashed all the hopes one can have from their handset.
