Lol, most of those are hilarious. Apple maps was never broken, in an unusable state, or showstopping in any way. It had a somewhat clumsy start but by no means was that a reason to avoid an apple device. The iPhone 4? Did you legitimately have an issue? I never used a case with mine and didn't have any issues. All smartphones at the time would lose signal if cupped a certain way in the hand. Battery issues in the 6S? The ones that cropped up years into use? The ones that were relatively minor and were good to go after a free replacement? I run IT for a couple of companies and the three cases of the bum 6S battery were all over one year old and frankly the users were happy that Apple was giving them a new battery for free. I literally have no idea what you're talking about on the rest of them mentioned.
I mean, go ahead - blow up the worry for yourself, but there isn't a world where any of what was mentioned made it a bad call to purchase an iPhone at any time.
And the Samsung thing? Call me when that happens to Apple - you can't compare across the aisle at this point as Apple has never, ever had a widespread issue as showstopping as that. The best thing about Apple is that they have a solid track record on hardware, and can generally be trusted. I'm going with "trust Apple" until they disappoint, then I'll be skeptical.
