I am a little nervous to install a major update from Samsung. With the 6.0 update it got into a boot loop and I had to completely reset the phone. I might wait a week and see what other people say about it.
I disagree. You have the built in Samsung cloud backup (search for "backup" in settings). You can temporarily backup your entire phone and the data is available to you for 30 days for free. Have you tried this yet. It does a phenomenal job restoring when things go horribly wrong with an update.
