I just got an iPhone 6S Plus 128GB. Although iOS has some significant drawbacks when compared to Android, it also has some very significant advantages which many people keep denying. Here's what I instantly noticed:
Advantages:
1)When I am without cellular connection for a while(basement of a building, subway, etc) as soon as I am out of there, the iPhone reconnects almost instantly. Android always takes around a minute give or take a little and rarely, it never even reconnects and I have to restart the phone to connect again. Never an issue with the iPhone. And no, my issue wasn't device specific. I had this problem on several Android phones over many years up until I got the iPhone.
2)When I turn on my GPS the iPhone gets my position instantly or in a very short amount of time. With Android, its a hit or miss. It may be somewhat quick, but it may also take much more than a minute. Sometimes it will get completely stuck and I will have to try again.
3)When making calls the iPhone almost always connects the call quickly. With Android, there are sometimes weird glitches, delays etc, before I can start hearing the other side or the call is connected.
4)When checking Weather, the current weather shows up instantly or very quickly. On the Android, it may sometimes take quite some time before this information comes up.
5)The fingerprint sensor is excellent... But, there's really no fingerprint sensors in the Android world outside of Nexus 6P and 6X. Please don't mention Samsung. Samsung phones are really, really bad. Only the camera and design is good. I am speaking from a very, extensive experience.
Really, when people say the iPhone is a phone that "just works" they mean it! Android may have all these extra great bells and whistles, but its all very finicky, and nothing is ever guaranteed.
Drawbacks:
1)There is no back button on the iPhone. Words can not describe how annoying it is to keep pressing that home button all the time, and having to keep closing the background apps all the time. It's an old, outdated system that should have been refreshed and revamped a long time ago. Apple is trying to play it safe and no change too much, but it's ridiculous really. It feels like using a phone from 10 years ago.
2)You cannot close all the background apps at once! Only up to 3 at a time. WHY?! Just.. WHY?! Stupid... Crazy.. Ludacris...
3)There is no notification LEDs. Again.. WHY?! Because Steve Jobs didn't have it in his design originally? But it's 2015!!! Madness....
4)There is no easy.. or reliable free way to transfer all your text messages from Android to iPhone. This is very upsetting.
5)The "live photo" feature is a useless gimmick. It's just totally irrelevant.
6)The "timeless" design is getting old. No, it's actually already old. Ancient even. It's time to move on! About 5 years ago.
7)Why is there STILL no quick charge? Not that it's a huge issue because when charging with an iPad charger it charges almost as fast as quick charging phones.
