The only thing i missed in textra was the ability for "Google Voice Typing" which is the little microphone under the button on the left of the space bar when LONG PRESSED. But if the microphone is not in the list under that button here's how to get it on a Galaxy S5 - Settings > Language and input > click on "Default" under keyboards > click on choose keyboards > then put a tick in "Google Voice Typing. Samsung keyboard should already be selected as the default keyboard. Now you will have the Microphone.
