Android knows that we all have different needs
Android is for everybody, and that includes people who need help seeing/hearing or otherwise operating their device. To this end, there are system-wide accessibility settings baked right into Android, and you can control them through the Accessibility section to the Settings app. It’s right at the bottom near "About phone" and developer settings.
Your own device may have much, much more — the LG G3, for example, has enough to fill a post all its own — but so long as you have Android, you should at least have these.
Open it up and let’s explore it together.
