Yeah that's unfortunately not how disagree works. You can disagree with opinions but facts are not something that we agree on they just are, and they are, independent of our opinions about them. So if you have accesd to factual information, and persist in statements that contradict said facts, then that is called lying. Now I am by no means trying to suggest that you are a liar so please do not take this that way. what I'm saying is that the iPhone is objectively not as bright nor easy to read in direct sunlight using the correct automatic settings. This is not a your mileage may vary type of situation this is an objective fact proven through the actual value, in this instance measured in nits, of each display when it actually hit speak brightness under these conditions. To state that it is otherwise would be dishonest and so when presented with access to the factual information on this matter, it would be okay to say that I had not noticed that this is the case to date but it would not be okay to state that you disagree with the information as it stands. what could perhaps make a case that there may be variation between units whereas some iPhones may achieve a higher peak brightness and some galaxies may achieve a lower peak brightness, in which case we would just assume that you were able to present some sort of data that this is the case and that those variances are extreme enough in order to justify the conclusion that Up Is Down and In is Out. The only alternative would be to concede the mistake and agree that we can move on by mutually accepting the facts. And indeed that probably would be the most honest and most acceptable alternative.
