I have a Tecla Shield (Tecla | Access technology hands-free) hooked into my wheelchair to be able to use my joystick to control my phone. Right now I am using the Tecla app, but the app has it's own keyboard that doesn't have word prediction. This makes texting or emailing difficult when you are a wordy person. I am told that if I use Samsung's Universal Switch I would be able to use the built in Samsung keyboard. I do not see this option available on my S5, nor do I have the option for Google's Switch Access even though I am running android 6. I just received this phone as a birthday gift a few months ago and upgrading is not an option. Is there any way that I could get Universal Switch or Switch Access on my S5?
