With Samsung phones, even if you try to disable the Messages app and install, for example, the stock android Messages app, it will pop a very annoying nag screen on your home screen warning you that the Samsung messages app is not the default, and the only way to remove that is to Force Stop the Samsung Messages app, which then restarts... The best thing to do is give the phone to someone who doesn't have a phone with the warning that it is full of crapware.
