Sorry if it's not the right place to ask but I've done a lot of searching to little avail. I'm wondering if it's a normal practice for unlocked international phones to come in unsealed boxes from sellers. I purchased Note 4 N910C from Amazon and returned it cause it came unsealed and tampered with. Then purchased Note 4 N910F, similar story, perhaps less tampered. Checked B&H, at least they're honest about it (in replies to customer questions) and say that those phones come in unsealed boxes because the distributor opens them to, I guess, remove the regional SIM-lock? Amazon policy does not allow such practice. Is this normal? Or am I getting refurbs sold as new? At $900 for the F model, I kind of wanna be sure. Why nobody seems to talk about it? If I'm wrong, links to discussions would be welcome.
