When I checked out the Note 9 in Bestbuy it was obvious that the screen was both brighter and sharper than my iPhone X screen. I then went and bought the phone in Anonymous Store (Canada) since they had the best deal. When I got the phone home I noticed the brightness of the iPhone X was greater than that of the Note 9. Just to make sure I hadn't changed any settings I did a factory reset of the phone, but the brightness didn't change even after setting everything to its maximum settings. I then took my phone into bestbuy and saw the one on display was significantly brighter than mine. I then took it into several other stores and mine was always dimmer. I then took the Note 9 back to the anonymous store and saw the same thing with the one on display, it was brighter than mine. I asked the store worker to swap it out for me and he refused. I then asked for a refund, he said ok where's the box, I then went to my car and got the box and got to see another store worker who told me he is not surprised that the phones being sold are not the same as the ones on display. He told me the Samsung phones were not reliable where as the Apple Phones on display are the same as the actual phone being sold and are reliable. I was stunned, to think that this was being done. Now I cannot vouch for what he said because I only got to try the phone that I had bought, but not good if this is the case. I just want to warn people that they need to make sure the phone you get matches the specs that are advertised. The Note 9 specs for its screen should make it way brighter than the iPhone X and not the other way round as was with my experience. Buyer beware. I have posted this because I could not find anyone else who has written about it.
