Hello Joy,
Thanks for using the forums, you can find an article on the subject here on Komando.
The iPhone 6, 6 Plus, 6s, 6s Plus and SE must have been running iOS 10.2.1 or later, and the iPhone 7 and 7 Plus devices need to have been running iOS 11.2 by Dec. 21, 2017.
Apple has agreed to pay anywhere from $310 million to $500 million to settle the lawsuit. The settlement still needs approval from the court before it’s official, but if it’s approved you could receive $25 for each iPhone owned.
