Drone is a "9G" mobile phone operating system that appears in Grand Theft Auto V based on Android. It is featured on all cell phones manufactured by BitterSweet, Badger and Whiz Wireless. BitterSweet's drone phone is based upon the Samsung Galaxy SIII or Samsung Galaxy Ace 2.
Its main competitor is iFruit OS which is featured on iFruit phones.
Drone is humorously described as copying the iFruit, similar to the real world accusations of Android copying Apple.
Periodically, the player will receive emails from various characters, or even companies promoting new items in stores. For some personal emails, the player can choose to 'reply' to the sender, and a scripted message from the protagonist will be sent, advancing the conversation. Emails from retailers sometimes come with a link that can be opened in the browser.
The text messaging function of the phone allows the player to receive texts from various characters. Viewing a text usually prompts the player to call the sender, often to advance a part of the story.
