It was launched in limited quantities and was quite a hit.
Samsung is now rolling out the April security patch to the device (SM-N935F) in Cambodia, Indonesia, Malaysia, the Philippines, Saudi Arabia, Thailand, and Vietnam. After the update, the phone will be on firmware version N935FXXS8CUD1.
We don’t have our hands on the changelog yet but, roughly speaking, it will fix some vulnerabilities within Android and Samsung’s software.
You can get the update by going to Settings – Software update – Download and install.
