Heads Up! Just received this email from Samsung.
You have been invited to participate in Samsung Device Insights Program. This study will allow Samsung to gain insight into how customers use smartphone and make improvements to products and services.
As a part of the program, we will provide selected candidates one of Galaxy S8 and Galaxy S8 Plus which you are required to install with Samsung Device Insights App. That will help us understand how you use your phones – things you like, things you don't. After 12 months of using the phone as your primary device and meeting the program requirements, the phone will be yours to keep
BTW: I previously sign up the insight program but never received any survey.
