Samsung Galaxy Z Fold 5
You may not need the Samsung Galaxy Z Fold 5 to get the latest features thanks to the One UI 5.1.1 update rolling out to all Samsung foldables, but the new book-style foldable is sure to be first in line to get future updates and patches.
Samsung Galaxy Z Flip 5
The Samsung Galaxy Z Flip 5 may not be a substantial upgrade over its predecessor, so you might not feel the urge to upgrade — unless, of course, the much bigger exterior screen is a killer feature for you. No software update could get you a big hardware upgrade like this.
