As of my last knowledge update in January 2022, the latest smartphone technology was marked by several trends. Foldable smartphones, exemplified by models like the Samsung Galaxy Z Fold and Z Flip, showcased a shift towards innovative form factors, offering users expanded screen real estate without compromising portability. 5G connectivity became increasingly prevalent, promising faster data speeds and more reliable connections, transforming the way users interact with mobile networks.

Camera technology saw continuous advancements, with multiple lenses, computational photography, and AI enhancements improving photo and video capabilities. 

High refresh rate displays, reaching up to 120Hz, became standard in premium devices, providing smoother scrolling and enhanced gaming experiences. Biometric authentication methods, such as under-display fingerprint sensors and facial recognition, continued to evolve for enhanced security.

It's crucial to note that smartphone technology is dynamic, with new developments emerging regularly. Since my knowledge extends only up to January 2022, I recommend checking the latest sources and reviews for updates on the newest smartphones and their technological features.
