Yea, there are things about iOS that I really like. Force Touch on previewing photos and web links without opening them is very nice. It's even more convenient that using S-Pen's air view, cause Force Touch works system wide(mostly).
And Encryption backup on iTunes is the absolute best. Sure Helium, Titanium, and etc on Android are options, but it's not close to being as reliable, especially when restoring to a differ model device.
I just switched from the S8+ to the Note 8 as my main device.
Getting used to Android ..... I can understand when people say that, up to a certain point. But some people just refuse to adjust. And IMO, it's really not a big adjustment.
The apps ..... I see almost no differences in 99% of the cross platform apps I used. Apple does have more exclusive apps though, especially education and medical apps. But I personally never came across an app that I had to have on me at all times that wasn't cross platform.
But I will admit, those that invested a lot of $$$$ over the years on apps, it's a hard pill to swallow paying again on a differ platform. But that goes both ways.
The unlock .... You mean the finger sensor?
Lack of Sync ... Restoring App data along with log-in info from using iTunes encrypted backup, that's the only thing syncing on iOS has over Android.
I can be on my desktop, then on my laptop, and go to my tablet, then go on my phone. All my Chrome tabs, history, and saved log-in info are synced. Cloud accounts like Google Drive, One Drive, DropBox, synced, contacts, calendar, photos, and etc. I use Enpass for my password manager on every device. Quickbooks also. Video and Music services, synced. My text messages and messenger services(like Whatsapp) synced. What else do I need to sync? My whole life is synced. LOL
There's so much syncing going on, that I have to manually adjust one of my Google accounts and Samsung account not to restore everything.
Anyone that complains about syncing options is just too lazy to transition beyond iCloud.
There was a time on Android when restoring app folders, icon/folder placement, and widget placement was non existent, and was a huge annoyance. But that's been resolved for years now.
Having your iPhone Calls and iMessages connected to your Mac, and all your other iOS devices. That's more of integration, not syncing. Apple wins at that. Sure they are alternative apps on Android like Samsung SideSync and AirDroid which work well. But it's just not as fluid as the integration with iCloud.
Now that I think about syncing ... I pretty much understand why Apple refuses to allow users to choose default apps. iCloud syncing would not seem so seamless and simple if users default app usage varied at a large spectrum. You can only have a one size fits all ecosystem if you force users to do things your way.
