Vivo's new flagship killer is designed with gaming and strong performance in mind. To achieve this, it combines a Snapdragon 8 Elite Gen 5 with 24 GB of RAM and even integrates a fan into the smartphone's chassis. Unfortunately, this comes at the cost of one great feature, although the affordable price remains unchanged.
