Maybe its time to root that phone! Samsung Galaxy phones are relatively easy to root, and you can pick and choose what version os you want, as well as have the ability to stop OTA updates to the os.
Every device in my household has been rooted and none of us have had an issue with them since rooting them! As a bonus, our phones/tabs have been much faster loading apps and doing stuff on them!
Just throwin' out a different idea to fix the entune issue once and for all. I'm a "KISS" kinda guy, if the phone works without issues, why update the os, or any of the apps if there's no problem? Surely I don't need any more bloatware on the phone from Verizon (my carrier), so being able to stop all of that is more than reason enough to root everything I own.
