My Note 4 accidentally upgraded yesterday after numerous attempts to not allow it. I now have no 4g access but wireless works. I run a business with this phone and need access at all times to my emails. Can this install be reversed back to the other OS? Can a class action lawsuit be filed against Verizon and Samsung for not giving us the option to install the update. This is similar to the Microsoft lawsuit with IE as a default web browser! Just my .02 on this horrible OS without any testing being done before the release.
