This update doesn't make sense to me. If I install, then it should be complete when finished installing. I feel Samsung is holding my notes hostage until I agree to the add on, which, as noted by many here, is "from an unknown source." This update is poorly executed, Samsung. LongHiker, I hope you are right that it's safe.
I fixed it. You have to click on the "package..." icon when it pops up and then click the setting gear that pops up. Then turn on the button allowing access to install. This is so dumb!!! Samsung is losing my interest real fast. There's so many cool things now on apple phones. Never thought I'd say that. Come on Samsung! Get it together!!!!
I found you. I made a new post reposting your suggestion. I was wanting to give you props. Thank you so much. My husband was having a fit so I had to save the day. I found your post. Told him what you suggested and it worked. Thanks!!
