Would you mind sharing with us what types of issues you are seeing? I searched Lollipop on the internet and notice that other users with the Samsung Note 4 are experiencing issues since installing the latest Lollipop 5.0 for Android.
If you would like to reach out to us with your cell phone number and a way to reach you at email@example.com we can see what we can do to alleviate some of these issues you are experiencing on your device.
Thank you, Tennille
