What is more accurate in the way we look in reality?

I know in certain mirrors you can look skinnier and taller and in others you look shorter and fatter and that goes the same for a camera. But in the mirror it looks like I have really short legs and a really long torso but on a video my legs look only slightly short. Which one should I believe? (the video was filmed on an iPhone 6s )

Does iPhone use data/Wi-Fi for texting?

I've been an android user for years now and just got a 5 so I'm totally new to this. Overnight turned off my data and Wi-Fi to conserve battery (as I always have with my android device), in the morning when I turned on my Wi-Fi I received a bunch of texts that were sent hours ago. Does this mean without Wi-Fi or data I can't text nor receive texts?

Data usage is not an issue for me since it is unlimited for me but I feel that it would become a hassle to constantly leave your data on to receive texts. Or maybe that's just me since I've been in the android world for so long.

What exactly is cellular data? - 1

I'm so confused about my iPhone data. I just got an iPhone 4 and I got a message saying I'm almost above my data limit. But I'm not exactly sure why. So can someone tell me what data is and if I turn it off and use Wi-Fi am I still using data? Can I still be charged? Oh I never intentionally used Internet without Wi-Fi. That's mostly where I'm confused.

My iPhone's volume turns up by itself?

I got a brand new iPhone 4S and it just randomly decides that the volume needs to be turned up. WTF?! It's not the case because I took it off and it still does it. It never turns down, only up. It mostly happens when I play games. This is so frustrating!

How to edit a video on Windows or using iPhone?

I've been required to write a "video essay." For my video, I did something similar to a "draw my life" video, with a whiteboard and markers. I'm done filming it, and I have several little video clips of me drawing and writing. How do I go about it from here? I just need to put all the clips together, speed it up, and then do a voice-over. I have an iPhone and a Windows computer; is there any software that works best for my needs?

How did Apple get such loyal customers?

Working for a cell carrier, broken iPhone are extremely common. I starting to think everyone either broke a iPhone know know someone who has. Yet people who know they are unsafe with phones continue to buy them. Apple some how convince them that it okay just buy another one, and they do? Apple the only company I know that can rip it customers off and they're happy about it.

I know it not the case iPhone is so great that nothing else will work for them because they refuse to consider anything else. They have no clue as to what the competition is doing.
