Samsung bait and switch
I had a S7 Edge that I was really happy with. Then recently they changed their contracts, and my phone started popping up a notification that I had to sign in to my Samsung account and digitally accept the new contract, to continue using my phone. I did NOT agree to some of the terms in the new contract. So I declined to "accept" it. Queue my phone popping that notification over the top of everything, every 60 minutes. Prompting me that I had not yet accepted the new contract.
Contacted Samsung, only to be told that there was no way past it, I had to accept the new contract. For a phone I owned and paid for outright. So would they buy the phone back at the same price I purchased it for? No.
Im with a Huawei P20 Pro now. Samsung has turned into a fetid steaming mess.
