The process of disabling Real-Time Text (RTT) functionality on Android devices involves adjusting settings within the device’s operating system. This functionality allows for text-based communication during phone calls, essentially displaying typed text in real-time to the recipient. Disabling this feature prevents the transmission of text during calls.
Disabling RTT can streamline call functionality for users who do not require or utilize real-time text communication. This can reduce the complexity of the calling interface and potentially prevent unintended text transmissions during voice calls. The introduction of RTT was intended to improve accessibility for individuals with hearing or speech impairments; however, its utility varies across users.
