HU. Received an email from Samsung for participating in the The Ultimate Test Drive Offer from last year so check your email! YMMV
Looks like you will get to keep the phone after 6months.
Thank you for signing-up to try Samsung's cutting-edge Galaxy phones under the Samsung
Ultimate Test Drive (SUTD) program.
While our teams re-evaluate on how best to take the SUTD program forward, we wanted to introduce you to a different program that Samsung has been running for several years now - Samsung Device Insights.
This invitation-only program is designed to include you, the customer, in the process of making sure our products and services remain best-in-class. As a part of this study, we will provide selected candidates one of Samsung's latest Mobile devices such as Galaxy S7, Note 5 and others. Installed with our proprietary Samsung Mobile Insights App, it will help us to understand how you use our phones – things you like, things you don't – without much effort expected from you after the initial set-up. After 6 months of using the phone as your primary device and meeting the program requirements, the phone will be yours to keep!
