Xperia Assist

This release does not have a Play Store Description, so we grabbed one from version 2.2.A.1.3:

The Xperia Assist application learns how you use your phone and adapts to give you our smartest and most personal experience yet.

The application brings a personalized introduction to Xperia essentials and gives contextual tips, exposing Xperia’s hidden gems and potential optimizations. These smart tips are intelligently selected based on your usage patterns and device surroundings. They are simple to understand and the content is rich with beautiful design.

Xperia Assist also brings you smart reminders to support you in your daily life. For example, if you forget to call someone back or switch off an alarm by mistake, you will be gently reminded.

This application uses analytics software to collect and aggregate statistics to help us improve this app and our services. None of this data can be used to identify you.

PLEASE NOTE that you must have at least Android 8.0 Oreo or higher in order for Xperia Assist to work except for Sony Xperia XA1 Plus.
