Best Smartphone Operating Systems

The Top Ten

1 Google Android

Best OS because you can costumize almost everything without root.

No doubt, if you own an Android smartphone, you know what I'm talking about. As an Android user, you can feel that the phone BELONGS to you. Full customization, no restrictions, easier to have and cheaper to get.
"Android all the way"

Android One is the as good as it gets

Android OS is what Apple OS failed to accomplish, even if it does sometimes crash.

2 Android Pie

More improved user interface, more tools added,.

BEST os. Better than Google Android.

Does some things I do not ask for

3 Apple iPhone OS

I like android but they really can't compete with the fluidness and overall simplicity of ios. No one beats apple at software.

Compared to Android, it has LESS features and apps and everything, and it's on the stupidly expensive above-value iPhone.

IOS 7 is just a clone of Android.

I changed my iPhone for a Nexus 5X, and after using Android 7.1.2 I have no doubt, I will go back to iOS phones. - Jukass

4 Microsoft Windows Phone

Windows phone OS are great they are not ram hungry. And very powerful apps and games can be used in windows phone with a low specification phones. And it's better than android and iOS In all ways. It's faster than all os. The only lacking is a small apps store but the store is now getting day by day.

Smart resizable tiles allow you to mod your entire phone to suit your individual use and content type needs. IOS widgets attempt the same but are limited to one screen with limited customization ability. IOS and Android currently lead the App Store battle but Windows 10 mobile is a far superior OS. IF/When Microsoft figures out how to make app porting easy (or unnecessary) they could easily leapfrog the others.

Windows phone os awesome, nothing to like windows, my vote goes to windows phone, popular future os

Unbelievably fast and stable. But Microsoft has experimented with its own remedy, the general lack of applications available to the platform prevents its expansion - Jukass

5 Nokia Maemo

Billy said it was great!

A full open source os. They even rub network penetration testing... It's the ultimate hacker os with proper linux os access to terminal. You can do anything to it... more customizable than android or meego... It is the besr

6 Linux MeeGo
7 RIM BlackBerry OS

I've used most operating systems and BlackBerry 10 is my favorite.

Menu items missing or slow to respond, Device temperature warmer than usual and Applications not opening.! - mwasoge

It is the best os I've ever use

I'm sorry... Best architecture, high security

8 Android Oreo
9 Microsoft Windows Mobile

I think windows phone has not got the proper attention that is why its being ignored by many people. The fastest OS for phone.

The Contenders

11 Microsoft Windows RT

18 ColorOS

Best android os... It's east to use

19 Ubuntu Touch

I'm sure this OS will compete with Android and iOS (which I both hate) and take a big market share like both Android and iOS. Here is a video that shows what its all about: http://www.YouTube.com/watch?v=h384z7Ph0gU
No other mobile OS has such awesome features and great patents!

Now using Tizen must admit that apart from lack of apps I'm presently surprised
