The use of this android-based mobile phone is very easy to convey a message to the intended person. Like being able to send messages via WA, Telegram, Instagram and other applications. So in this way humans are faster in sending a message. Although it is not widely used, there are still people who send messages via SMS, and not everyone also has a mobile phone with an Android operating system.
