As someone who uses phones for many tasks, the performance difference is not something I can overlook. The smoother scrolling experience thanks to the 90Hz display, combined with the added camera quality is something I value.

While the Samsung Galaxy A03s might be tempting for its lower price, the Nokia G21's overall package—including better performance, a smoother display, superior camera, and the latest software updates—makes it a much more compelling option in my eyes. It's a device that is not only good today, but will perform better over a longer period of time.
