Well, I have had the two experiences with Swappa. The first one wasnt good, but second one is great. The seller Circas is terrific. Not only was my Note 9 exactly as described, but there is even a warranty on the device until May next year.
I dont really care personally that its going to be done with security updates soon. Its still a great device with certain features that no phones have had since, and I still have a device getting regular security for awhile, so no problem there.
I am mulling over whether I should return this though and get the 512/8GB RAM version for a little more future proofing. I dont really feel like paying an extra 80 dollars though when this is already a budget purchase lol only thing I would utilize is the 8gb of RAM, and I dont think its worth it for just that.
