1. If I wanted to make a list of complaints about the iPhone; I wouldn't. There are tons of them.
2. Even if I decide to do that, I wouldn't sign a 2-year contract and purchase an AU$1800 device. At my company, we had 20+ devices to test apps we develop. I could've just used one of them. OR I could have used all the iPhones we had (4, 5, 6, 7, X) and make a list of complaints about each of them individually. I was really excited when I bought it.
3. This is exactly what my article is about. It is a well-engineered phone with nice software that lacks testing in "real-world scenarios" and has a poor user experience. I'm aware of the sensors. I work with them on a regular basis. To put the phone in your pocket, you have to hold it first and you are touching the screen. If you own an iPhone, just make a call, place it on a table, lock the screen, and randomly tap on the screen and tell me what happens. During a phone call, I would expect the screen to be locked, no matter what.
4. Can you show where/when my second point (disabling shutter-sound) is contradicted? I'm not talking about muting the phone. My point is about disabling the shutter sound without changing the top-level volume of the device. It is impossible. You have to silence the device.
5. I checked this one and it doesn't happen on Galaxy devices either. Apparently, this is a functionality that changed with recent smartphones. In the past, even if you turn off the device the alarm would work. I guess I haven't been in a situation to test this with my Galaxy device in a long time.
6. English is not my native language, sorry about the grammar.
