Bubbles in messages refer to a feature in Android devices that allows users to create a floating icon for a conversation, making it easier to find and respond to messages. Bubbles are built into the notification system and float on top of other app content, following the user wherever they go. Users can expand bubbles to reveal the conversation and collapse them when theyre done. Bubbles can be enabled by opening the Messages app, going to Settings, and enabling the Bubbles feature. To create a bubble for a conversation, users need to swipe down from the top of the screen, touch and hold the chat notification, and tap Bubble conversation. The blue speech bubble next to a contacts name in an iPhone indicates that the corresponding number is capable of accepting text messages (either SMS or iMessage) . The conversation bubbles in Verizon Messages+ dont signify anything by default, but they can be customized by users as a way to organize their contacts.
