I would have to agree with you, some devices do not make it easy to replace the battery. The Galaxy J3 V is very simple. Remove the phone's back cover by placing a fingernail in the notch on the side of the phone and gently lifting the back. Remove the battery by placing a fingernail in the release notch at the bottom of the battery and lifting it toward you. Then you simply do these steps in reverse with the new battery.
