Android Ice Cream Sandwich vs Apple iOS 5 best features

This will be the one of the most difficult comparisons to be done. For one thing, Google and Apple have both recently unveiled huge changes that respectively make their mobile operating systems far more powerful, and in some ways more similar to each other. For another thing, weighing the pros and cons of each platform against the other is a scenario that's played out daily among many people who are deciding which phone to buy.

Android Ice Cream Sandwich 4.0	Apple IOS 5
Bold, powerful UI For those who already use it, there's nothing hard about Android. Yeah, you have to know that sometimes you need to access the menu or long press for more options, and there are some extras you can get by swiping in certain places on the screen. But no other major OS can top Android's flexibility in terms of customizing the multiple home screens with stills or moving animations; widgets galore; and apps, apps, and more apps. Ice Cream Sandwich ups the ante by making widgets resizable, too.	Dead-simple UI You can't argue with the idea that when you pick up an iPhone, you already know how to work it. There are increasingly more hidden tricks: taking screen shots, opening the "multitasking" menu, accessing universal search, operating the notifications pull-down, and launching voice actions (or Siri), but for the most part, what you see if what you get, and there aren't any hidden menus in the apps. Those standardized icons are easy on the eye, too.
Turn-by-turn voice navigation For many people, this is the platform's ace-in-the-hole. Broken out from maps, Google's turn-by-turn voice navigation for driving directions can effectively replace your in-car dash or GPS navigator--and possibly save you hundreds of dollars.	Siri Probably iOS 5's most buzzed-about feature, Siri is the voice-triggered assistant with an attitude that replaces the Voice Control app. She's fun to talk to the way you would converse with another person, and comes up with some snarky responses to some inquiries that make her the talk of the town. Much like before with voice commands, Siri can create reminders, search for directions, text people, call you a cab, and so on. The real innovation is the flexibility in which you can phrase your questions, like: "Do I need an umbrella today" rather than "Weather San Francisco." Ultimately, the shot of personality is fun, but the abilities aren't substantially different than what's already out there. Besides, like all voice command apps, Siri's comprehension ain't flawless.
Camera tools Ice Cream Sandwich brings on a whole lot of new photo tools, the most significant of which are the photo-editing tools in the image gallery. They include red-eye reduction, straightening, and "hipster filters," whatever those are. The camera app itself adds a useful panorama mode that seamlessly creates a landscape still.	Camera As I mentioned above, this one's stickier because there's no way to completely separate the hardware and software. The camera app interface in iOS 5 is simple to operate, and not very deep, but there's great editing software behind the scenes that help photos render with crisp detail and good color representation, even on an iPhone 4 running iOS 5. HDR mode is a nice plus. However, the camera's lens and image sensor qualities also play a significant part in the making of good mobile photography.
Openness The benefit Android's openness to other manufacturers' custom interface designs is debatable depending on which side of the conversation you're on, but it gives cell phone-makers and carriers the opportunity to offer new features and visual experiences that are variations on the Android theme. Some people prefer stock Android, just as Google designed it. Others appreciate accessing tools and information in ways that Google didn't envision. The company has clearly borrowed some innovations from these custom UIs, like bring able to open a specific app in conjunction with unlocking the phone (rather than unlcoking to the hom page, then opening your app.)	iCloudOne of iOS 5's most significant additions, iCloud does over-the-air syncing from the device to the cloud (no more USB connection to the computer!) and syncs content like apps, music, and contacts, so you can later restore. You can also wirelessly edit photos, manage e-mail folders, and create and delete calendars. iCloud is an excellent resource for syncing music you own.
Facial unlocking Android Beam is fun too, but I think facial unlocking is even more novel, fun, and interactive because it (optionally) uses the front-facing camera to recognize your features and let your into your phone. So smile! It's also wholly unnecessary, but a harmless party trick.	Music integration From the very beginning, iTunes and iPod integration is what made the iPhone a killer. It's simple to store, play, and buy music. iOS 5's wireless syncing forgoes the need to plug your iPhone into the computer to sync songs. Now, as long as it's charging while you're connected to Wi-Fi, you can set it to automatically sync with iTunes.

Android Jellybean top 7 features

Android 4.1, Jelly Bean, is the fastest and smoothest version of Android yet. Jelly Bean improves on the simplicity and beauty of Android 4.0, and introduces a new Google search experience on Android. Here are the top 7 features which make it the best android version yet.

It's smooth and fast as "Butter"
According to Google, Jelly Bean will provide far more responsiveness than its predecessors. 
Transitions are happening very smoothly and Google had accomplished this feat from a project called "Project Butter". Google put Android under a microscope, making everything feel fast, fluid, and smooth. With buttery graphics and silky transitions, moving between home screens and switching between apps is effortless, like turning pages in a book.

More reactive and uniform touch responses mean you can almost feel the pixels beneath as your finger moves across the screen. Jelly Bean makes your Android device even more responsive by boosting your device's CPU instantly when you touch the screen, and turns it down when you don't need it to improve battery life.

Notifications serve you as your personal assistant
Notifications are not the colored text anymore. It will guide your day and allow you to take actions within the notification panel. Android has always put you in control when it comes to staying notified and connected. Now you can take action directly from the notifications shade. Late for a meeting? Email everyone to let them know. Missed a call? Call them back in an instant. And because they’re expandable, you can get an even deeper look into the things that matter most, like multiple emails or photos on Google+.

Bye Bye "Siri", It's "Google Now"
We’ve heard rumors that Google was working on its own Siri, codenamed Project Majel, or whatever you want to call it. Google announced their own version of Apple’s Siri with jelly bean, and it brings just what you would expect. If Google Now detects that your usual route is currently bogged down by traffic, it will redirect you onto a different path which will help you arrive at your destination faster. If you have a meeting on your Calendar, Google Now will direct you to get you to your destination as soon as possible. If you have a flight at a local airport, Google Now will give you information on where your flight gate is, and your flight details.

Touch n Send with Google Beam
Android Beam was supposed to be the next big thing in near-field communication(NFC) . However, it never really took off in Android 4.0 (Ice Cream Sandwich).  To address that in Jelly Bean, the company made it easier to share information by leveraging Bluetooth. Now, users can share images, videos and other data without worrying (too much) about how well the transfer will go.

Favourites can take more space
Android 4.1 introduces improved App Widgets that can automatically resize, based on where the user drops them on the home screen, the size to which the user expands them, and the amount of room available on the home screen. This will allow the users to resize their favoutrite apps as for their preferences.

Think before you write
Android's dictionaries are now more accurate, more relevant. The language model in Jelly Bean adapts over time, and the keyboard even guesses what the next word will be before you've started typing it.
With improved text-to-speech capabilities, voice typing on Android is even better; it works even when you don't have a data connection, so you can type with your voice everywhere you go.

Put all your eggs in one basket
This is not about eggs. It's about jellybean. Put the waste in to your recycle basket.
Android 4.0, Ice Cream Sandwich, made snapping photos super fast; Jelly Bean brings that same speed to the next step: viewing. Just swipe over from camera to filmstrip view to instantly view the photos you just took, and quickly swipe away the ones you don’t like. Now sharing — and bragging — are a breeze.
