I am currently on 4.1.2. Running stock settings and have not rooted. Prior to the update released this year, I was able to use app2sd to move 3rd party apps onto my external SD. Since the update, it no longer works. I contacted both Verizon and Samsung to find a solution. Both have told me no. Anyone experiencing the same issue? I don't like removing apps that I use a lot to make room for other apps I want. Thanks.
