Your points replied to:
1. Disjointed navigation between apps (non stacked based) (This is your preference I don't like stacked, like it is in safari I prefer the card layout)
2. No global back and task buttons (You just swipe left from the left side of the screen its much more simple than swiping up the virtual controls to then click back)
I think you didnt get I am saying. Maybe you are not familiar with Android.
I am talking about how to navigate between opened apps in a logical manner via the stack and global back.
A very common use case.
1. You are doing something (say reading e-book). Notification comes in (whatsapp/email/whatever). Say whatsapp
2. Click notification to view message. Inside the message is a web link. You want to see the link before replying.
3. Click on weblink to open web page. Inside the webpage there is also a youtube video
4. Click on video to view.
On Android after I have done with (4), I tap global back button and I am at (3) to finish the article, then I tap back button again and I am at (2) to type and send my reply and then I tap back button which takes me back to what I was doing before in (1).
Using Iphone, you have to use your task manager to switch back and forth to previous app every step of the way and making a conscious effort to remember what you were doing before and which app to move back to up the chain. This is so much more tedious require effort and steps/taps. Imagine navigating web-pages (i.e. apps) without a "back" and solely relying on "url history"
3. Convoluted Settings implementation (Convoluted compared to Android??? Wow. Android has the most messy settings menu i've ever seen. Can hardly find what I'm looking for, again showing More isn't better)
Iphone: While in app, press home, find and open main "Settings", scroll through long list to find and change items related to app, open task mgr, switch back app.
Android: While in app, press menu, select and change settings value. Done.
Need I say more
4. No support for shortcuts (Short cuts for what? You're most used apps show up when you pull down on the screen for easy access)
Not talking about app. How about shortcut on homescreen which takes you directly to battery screen in "Settings" (or any specific screen in any app - e.g add new contact screen). Or a direct sms to one of the numbers of a contact. Or shortcut to open a specific PDF file in the internal storage directly.
5. Slower scrolling rate (I haven't had any issues with scrolling speed on either devices.)
I have no issue app opening milli-seconds slower is a deal-breaker either (well, many here like to tout the A11 processor). My original point was if galaxy opens an app in 0.5 secs and even if iphone 8+ can open the same app 10x faster at 0.05 sec, so what? Does it affect usability? Don't think so.
But what matters more is the Iphone scrolling rate is still slower. In order to scroll through the same long page/list, it takes 3-4 times as many swipes compared to Android (..ios11 is better but still nowhere near the scroll rate of android). Having to swipe 3-4 times more is much noticeable and detrimental to usability than 0.45 sec longer.
6. No USB host support (Something I don't need)
7. No user accessable file system. (The file system is something I don't like on android)
It just shows you preference is rule of thumb here. You like what you like, I've never knocked anyone who uses android it doesn't bother me I don't care. I prefer iOS and therefore continue to use iPhone. I tried the S8 cause i loved its design an OLED screen but android was hard to adjust to.
I am not knocking anyone preferences. But making a preference sounds like it is better overall without even knowing fully (or not wanting to know the benefits) how the alternatives work is not right.
e.g. above USB support. I have friends with iphone that are very apprehensive about taking 4K videos while on holidays/outings due to running out of space (before they make it back home/hotel to offload). For me I just bring along my credit card size SSD drive which I just plug directly into my S8+ via usb and offload videos in phone directly anytime at USB3 speed.
