I am thinking of getting a Galaxy S6, second hand, as it's considerably cheaper than what I'd expect.
That said, I am slightly worried about grabbing it after hearing horror stories of buying second hand phones.
I am going to see the seller in person, so I think I could test few things before finalising transaction.
I've been thinking of checking these, but I am not sure whether I have a complete list:
1. Water Damage Seal
2. IMEI/SN check
3. Check whether KNOX counter has been tripped
What else would you guys check if you were in my posistion?
EDIT: After meeting with the seller and checking the phone, I've decided to grab the phone (it was cheap and she didn't seem to be scamming).
I've checked with Samsung Australia and transferred the warranty to my name as well (I've checked that this was possible before purchasing it).
I would check the seller him/herself. Most dodgy people are amazingly bad at disguising themselves as not dodgy so if they give off a bad vibe (I'll let you use your imagination on what a bad vibe could be) then it was probably too good to be true. Think of a good excuse and retreat.
Also, unless it's a low value item, I discriminate against sellers with bad spelling and grammar. Even the bad vibe of dodgy sellers permeates through their written communication.
