I'm sorry but that is pure ******** I've been trying to get a disabled person a tablet and had to get an Android one because of the lack of mouse input on the iPad (which is his only input option) So I tried the Samdung Tab 3 8" 4G because it had one of the newest Android versions where you could configure a home button on the screen (again to use with a mouse only).
Well, the mouse somehow stopped working after two seconds of inactivity because of a stupid error in the way the tablet handled USB power, the wifi version worked without problems (we tried it in the store) but the 4G (and otherwise identical) version didn't.
Well, we called Samsung Denmark support, when I told him the model number he was incredulous, he didn't believe me, and he couldn't find the model on his website (I kind of knew that because searching Samdung.dk for the model number came up empty) Long story short he was unable to help and promised to call back after checking with his superiors. Never called back.
We also took it back to the store and they also promised to call back "after checking with his guy at Samdung" he as well never called back, so we had to take the tablet back for a refund.
Meanwhile I was calling Apple support to exchange a faulty USB Apple charger and a pair of EarPods, well the service representative apparently did something goofy, because the support emails I got with info on how the repair/return was going had some funny foreign names instead of my own, I contacted support to let them know, and this extremely helpful, attentive and apologetic almost to a fault, said that she would monitor the situation, and call me back when I had returned the items (in the return UPS envelopes), lo and behold, when the faulty units were safely back in apples hands and I had gotten me a brand new pair of EarPods and a new charger, she called me and apologised for the weird error, and again assured me that everything was good.
That is good support, that is what makes customers happy, that is why I will shy away from anything Samdung makes, that is why I have a hard time believing this study.
Could you imagine a phone conversation with apple going like this: "Hello, thank you for calling Apple, my name is McIntosh how can I help you?" "Yes I have this iPad that doesn't work!" "Hold on there cowboy, did you say iPad? I'm afraid I don't know what you're talking about, can I have the model number on that bad boy?" "Model number I really don't know, it's an iPad! an iPad mini to be exact?" "iPad? are you sure? I'm afraid I can only find iPod and iPhone in our system, Sir are you sure the model number is iPad?" "Yes I'm god damn well sure it is!" "Well I can't find it so I'm afraid I can't help you" and so on...
(edit: I might have spelled Samdung wrong a couple of times, seems there's a problem with my "s" key wireless apple keyboard)
