Snap’s biggest project for the coming year is to reengineer its Android app. Snapchat has been notoriously slow and buggy on Android smartphones, and is virtually unusable on lower-end Android devices that have slower processing speeds and lower quality cameras. Such is the curse of a social media platform based on data-intensive content like photo, video, and augmented reality. Snap’s goal is to make its Android app 20% faster in 2019. Snap executives have been cagey about when this update will be ready.
