Android accessibility options for blind and hard of hearing users

A look at some of the accessibility options available in the Samsung Galaxy S 21 and other devices with Android 12.

You might have end users within your company that are either blind, deaf or hard of hearing. For those users, consideration must be taken to meet their needs. The need for accessibility doesn’t stop at the users’ desktops, because they must be able to leverage technology like any other employee. Thankfully, most smartphones have accessibility features built in so that the device works with them, not against them.

The newest iterations of Android offer a number of features that can easily enable the mobile device for those who are blind, deaf or hard of hearing. I will use the Samsung Galaxy S21 particular device to illustrate how Android works when accessibility is in order. Not all needs can be met, but these options can go a long way to help out many users.
