How can I make the keyboard bigger on my Samsung Galaxy J7?

[amigaloca]

I hit the wrong keys a lot when I type using my Samsung keyboard? Is there anyway to increase the overall size of the keyboard, so the letters and numbers are bigger?

Go to Settings>Language & Input, and select the Samsung Keyboard option. That should show you all of the options for the keyboard. If there is no option to increase the size of the keys, then consider one of the many 3rd party keyboards available on Google Play. Swiftkey and Gboard (Google Keyboard) are both good options.
