Samsung is currently expected to launch up to 4 new foldable devices this year, 1 of which will be a next-gen Galaxy Z Flip. Fresh renders of this clamshell phone have popped up with the same main camera module as the Galaxy S21 or S21+. Should this rumor be correct, it could launch with triple rear cameras and more space for a front-facing display.
