This is a notice to inform you that the “Smartphone Emerging Technologies” course will close for new learner enrollment on September 17, 2018. Since you have already enrolled, you will continue to see it on your Coursera Dashboard as long as you remain enrolled in the course. If you are interested in earning a Course Certificate for this course, please upgrade or apply for Financial Aid by September 16, 2018, if you have not already done so. In order to earn a Course Certificate, you will need to complete all graded assignments, including peer reviews, by March 17, 2019. After that point, no new assignment submissions will be accepted for Certificate credit. The reason to close this course is because a new upgraded "Emerging Technologies: From Smartphones to IoT to Big Data" Specialization has been prepared and will be launched in a few weeks. This new upgraded Specialization includes 4 courses titled “Big Data Emerging Technologies,” “Smart Device & Mobile Emerging Technologies,” "IoT (Internet of Things) Wireless & Cloud Computing Emerging Technologies," and "AR (Augmented Reality) & Video Streaming Services Emerging Technologies." These four courses (which all include projects) include the contents of the former courses, but with much more new state-of-the-art technologies added. Among these courses, I highly recommended you to take the “Smart Device & Mobile Emerging Technologies” course because it includes new details on smartphones, smart watches, 1G ~ 5G mobile technologies, smartphone OSs (Android and iOS), and the ranking of smart device services/products, along with smartphone mobile network analysis projects. While we hope that you will be able to complete the course, you can find more information about requesting a refund (https://learner.coursera.help/hc/en-us/articles/209819043-Request-a-refund) or unenrolling from a course (https://learner.coursera.help/hc/en-us/articles/208279756-Unenroll-from-a-course) in our Learner Help Center. We sincerely thank you for your interest and contributions to this course. In addition, we sincerely hope you will be interested in the new courses as well.
