Audible alerts for incoming calls on devices utilizing the Android operating system encompass both the sound a phone emits to notify its user (ringtones) and the audio a caller hears while waiting for the call to be answered (ringbacks). An example is the default chime signaling an incoming call on a standard Android phone, contrasted with a customized song a caller might hear instead of the standard ringing sound.
These audio customizations play a significant role in personalizing user experience and brand identity. Historically, basic tones were the sole option, but the advent of digital music and mobile technology enabled users to select and even create personalized audio signals. This personalization offers a form of self-expression and can serve as a marketing tool for businesses. The availability of diverse audio options has become a standard expectation for mobile phone users.
