Customers are saying

Customers recognize the Galaxy S23 Ultra 512GB's exceptional camera quality and long battery life as significant strengths. Many appreciate its ease of use and the large, high-resolution screen, with some also highlighting the included stylus and ample storage. A minor drawback mentioned by a few customers is the absence of a microSD card slot for expandable storage.
