Introducing the Care+ Diagnostics app, which is exclusively accessible to customers who are enrolled in the Samsung Care+ Program. You can now easily run diagnostics on your enrolled device when you purchase a plan within this program. If your plan is eligible, you have a generous 10-day window from the Plan Purchase Date to complete the diagnosis. To begin the diagnosis, you must receive a valid activation code via email. Once received, you can begin the diagnostic process. You'll need a second smartphone or tablet to capture images of your enrolled device for the diagnosis. The app will walk you through the diagnostic instructions, ensuring that you capture all of the required images correctly. After capturing the necessary images, the system will analyze the device's health based on the diagnostic results, determining whether or not the diagnosis was successful. If your diagnosis is successful, your plan will be activated, granting you access to the Samsung Care+ program. Don't worry if the diagnosis fails; you will have a second attempt to perform the diagnosis. This gives you a better chance of addressing any potential issues with your device. Please keep in mind that if both diagnosis attempts fail, your plan will be canceled. Download the app and enjoy the convenience and reliability that Samsung Care+ offers.
