Chosen Solution

I cant send a text because I get a message that keep saying that the Samsung keyboard has stopped

Not exactly a solution, but maybe a workaround, Try installing a third party keyboard, it should be possible to do without using the built in keyboard. Try Swiftkey If that still doesn’t solve the issue try backing up your phone and resetting it. Connect it to a computer and pull everything off of it, this should also be possible to do without using the phone’s keyboard
