The basic features of the handset beyond call functionality include an alarm clock, a calculator with tip calculations and unit/currency converter, calendar, stopwatch, world clock, and notepad. The phone allows creating an
In Case of Emergency (ICE) contact list for emergency access when the device is locked. The user interface of the Verizon device only has English and Spanish display languages.
Storage The
Juke includes 2 GB of pooled internal flash memory, of which up to 22 MB is available for pictures, ringtones, sounds, and applications, while 1.87 GB is dedicated storage for music only. The phone does not have a microSD card slot, therefore users cannot expand storage beyond what's available.
Phone and media management Over-the-air
V CAST music downloads are not available. The handset does rely on V CAST Music Manager software as another way to transfer music to the phone, and that program only supports Windows XP, Windows Vista and Windows Media Player 10, but not Mac OS X or any other operating systems. Music is transferred through an MTP device allowing Windows, Linux, and Android users to download music files from their computer, while Mac OS X requires Android File Transfer for its MTP access. The phone's non-music storage is accessible with
BitPim, an open source and multi-platform application to access CDMA phones of various cellphone manufacturers.
Music player The device's music player supports
MP3,
Windows Media Audio (WMA and WMA Pro), and
Advanced Audio Coding (AAC and AAC+) file types by default, instead of converting all formats to the WMA format, like most other
V CAST phones require. Though it can't play
MIDI,
SMAF, PMD, QCP, and
iMelody files in its music storage as they instead have to be loaded into its phone storage in My Sounds (or My Ringtones). Music player features include an equalizer and 3D sound settings, playlist creation and music playback by artist, genre, and album. The music player's UI skin can show a visualizer, album artwork or lyrics. When in use, the music player can mostly work in the background; it pauses for phone calls, but stops for outgoing calls, at app launch, and at music synchronization.
Messaging In addition to text messaging (SMS), the device also utilizes picture messaging, which among other things allows saving received pictures and audio, including setting the latter up as ringtones. The phone supports sending and receiving e-mail. The handset also includes Mobile Instant Messaging, which uses data calls, and supports
AOL Instant Messenger,
Windows Live Messenger, and
Yahoo! Messenger. These protocols are no longer supported as of 2015; for example, Microsoft has migrated its users from Windows Live Messenger to Skype. Mobile instant messages are charged per Verizon's text messaging plan. ==Operator-dependent features==
