Does seem very odd that it takes 3 years to get around to suing over a device that was first released in 2016... just upgrade and get over it.. and how many devices did it actually affect? If it were as bad as it always gets made out to be, it would not have taken this long to get to this point.. Course let Sammy have a crummy device, and no one cares to bother to sue..
The 3 years is more indicative of patience with Apple to fix the issue. They have not done so. Simply upgrading and getting over it is not the customer experience a company can or should live on. Nor is it an experience that customers, who drop thousands on this company's devices, should have to simply stomach and move on.
