All options are personal. Some people are used to using iPhone or are big fans of Apple, they may never use Samsung. For them, they may know that Samsung is better than iPhone in some aspects like camera, resolution and battery, but they don't care, according to them, they may think that Apple is easy and simple to use, so they choose iPhone. On the contrary, some people may differ, they may just do like Apple or the big fan of Samsung, so they ignore all the advantages of Apple, instead of choosing Apple, they may prefer side screen, want to change themes every day, they may want the camera from 16 megapixels, so they prefer Samsung. According to my interview, I also tried to ask what the best-selling product is this year, but he said he can't answer this question. What he said was that “it depends on which one comes out now. If Apple just released a new phone recently, Apple absolutely sells more, but if Samsung just released a new phone recently, without a doubt Samsung sells more. But because of the multiple choices offered by Samsung, they may have a greater preponderance.” In fact, I even took a survey to ask my ten classmates which cell phone they are using right now and why they choose this one. The result is interesting because all of them are using an iPhone right now, no matter if iPhone 4s 5 or 6, they prefer Apple instead of choosing Samsung. Two of them said they have the Galaxy series, but think Apple is easier to use. Most of the answer to why he chooses iPhone is because iPhone is easy and simple, some people said, because he likes Apple, and one person said because everyone uses iPhone. Based on these answers, we can say that the iPhone indeed influences the way people use it
