This has led to the fact that nowadays the best teletypes for communication not only use wireless communication capabilities, but also switched from traditional printers to liquid crystal displays. Next, it will be detailed what is a teletype in "Android" or on other devices.

The main target audience of teletypes are people with hearing impairments. For them, this function is a very convenient tool for communicating, as well as receiving and transmitting information.
