As the app's user base grew, so did its compatibility with various operating systems. In 2012, WhatsApp became available on Android devices, including those running Android 4.0 (Ice Cream Sandwich) and later versions. However, it wasn't until 2013 that WhatsApp optimized its app for Android 4.4 (KitKat), which included Android 4.4.2.
