WP7 vs. iOS4: Multitasking, Copy & Paste, Suspend

If you’re looking for app switching in the manner supported by iOS 4.0, Windows Phone will disappoint. There’s no Apple-like multitasking supported by the OS at launch. Windows Phone 7 doesn’t totally regress in this regard. This is where the back button comes in.

The back button in Android literally takes you back screens until you land at your home screen, at which point it stops functioning. In Windows Phone, the back button is more like the back button in a web browser - it takes you back, in order, through every app/window you’ve visited.

Let’s say you’re typing a text message and you want to double check something you received in an email. There’s no conventional multitasking support so while you’re in the messaging app you’ll hit the Start button, and tap the email tile to find the message you were looking for. Now to get back to your text message, in a conventional smartphone OS without multitasking you’d hit the home/start button, and launch the messaging app again. That’s how it used to work in iOS. In Windows Phone however, hitting the back button will take you out of the email app and back to the last app you were in. In this case, that would be the messaging app.

There are rules for how the back button works. First, never use it after midnight. The history removes almost all references back to the Start screen with the exception of the most recent one. For example, if this is the path you took:

Messaging -> Start -> Email -> Start -> IE -> Start -> Zune

Continuously hitting the back button would take you to those screens in this order:

Zune -> Start -> IE -> Email -> Messaging

You always get the most recent Start screen in your history in case you, literally want to go back to the screen you were just at. Everything else however assumes that you’ll just hit the Start button if you want to go home and you’ll just traverse through apps you’ve visited.

The history doesn’t grow by using the back button. For example, if you launch the messaging app, hit back and then launch your email, hitting the back button will only get you back to the Start screen.

It sounds like a complex series of rules but honestly it just works for the most part. The back button really shines when you launch an app from within another app. Then there’s no going back to the Start screen, you just switch between the app you’re currently at and the one you were at prior to it. It’s like a one-tap task switcher.

The back button doesn’t completely negate the need for iOS style multitasking, but it gets you around 90% of the way there. Copy & paste is the other glaring omission, but Microsoft has already committed to deliver clipboard functionality in early 2011. We’ve privately seen a demo of the feature working, Microsoft is still ironing out the best way to make it happen within the Metro UI.

Windows Phone does support suspend/resume of apps. When you switch away from an app and later return back to it, the app will pick up where you left off - similar to what iOS4 enabled. All that’s really missing is the ability for 3rd party developers to have portions of their code run in the background and some sort of task switching mechanism.

    "Flipping through pages upon pages of square app icons just isn’t the most efficient way to do it. Folders help reduce the clutter, but they don’t fundamentally address the problem."

    Try placing folders onto the iPhone dock. I've placed 4 folders there. Tap on the folder (in the dock), and it opens up the folder, then tap on the app. This look like 4 mini "start buttons" - very convenient, and looks very good.

    FYI Anand - there's a dedicated Facebook app in the marketplace that was posted today. Actually created by Microsoft, not Facebook. Any chance you can update this article or write another quick one once you have a chance to take a look? The screenshots in the Zune software look interesting, at least.

    The xbox live integration on this alone makes it a much more attractive platform that anything else out there.( i thought I was going to have to buy an xbox for the new plants vs zombies exclusive content, lol) I'm looking forward to WP8. Many persons have sold WP7 short without anything to actually go on, but now, it already seems like the most complete platform out there. Full windows integration, ZUNE, XBOX and Facebook.

    All sounded great for me until IE mobile - What a let down.
    Basically a deal breaker. Other faults I reckon I'd be happy to live with until they fixed them.
    My high hopes sunk :(

    How did this let you down? The article didn't really have much of anything to say negative about the IE browser included in Windows Phone 7. Unless you're just one of those people who hate anything with the name IE or Internet Explorer...

    If you haven't already, try the IE9 Beta for Vista/Win7. It's a huge improvement from their previous versions, and you may just like it.

    Did you read page 9 (Rebuilding a Brand: IE mobile)?

    The benchmarks, blocky text and..
    "Slower page loading times aren’t as big of a deal anyways, since you can leave the browser and go do something else entirely while the page keeps loading."
    This statement instantly reminded me of dial up internet - not a smart phone.
    I don't open a browser to then go and test my multi-tasking or my patience.

    Like I said - I'll wait for now. If IE mobile is fixed I'll seriously reconsider.
    I don't currently have a smart phone and had been patiently waiting for win7 phone as I thought it might be The One - but it looks like I'll continue waiting.

    And I don't think browsers for PC have anything to do with a phone review - Thanks anyhow.

    I dont think the benchmarks matter that much if actual real world browsing is still good, which it is, and that sites are rendered correctly, which they are.
    Compared to the current state of many other phone browsers at the moment IE on WP7 seems atleast decent. Other browsers might have greater speed and specs on paper but they wont run as smooth and they often have trouble displaying certain pages.

    Just read the Engadget review and they also like the browser:

    "we've got to say that web browsing on Windows Phone 7 is actually a really pleasant experience. "

    "Loading the desktop version of Engadget was just a hair slower than an iPhone 4, and just as importantly, rendering new parts of the page as you scroll is plenty fast -- not instantaneous, but fast enough so that you never find yourself consciously waiting for it to catch up. Zooming -- which is accomplished with a pinch gesture, of course -- is buttery smooth. The phone accomplishes this in the same way you're probably used to from other devices: when you first zoom in, it uses the same render resolution so that it can at least show you something without going blank, then it renders the appropriate level of detail as it catches up (Google Maps works the same way on almost every platform). It works well. Zooming in and out of a page -- even when still loading up content -- was super fast in our testing, and rendering happened in a split second, meaning hardly any time spent looking at jagged pixels. We're tremendously impressed with how well the browser works "

    However they go on to mention that because of no Flash (yet, Adobe are working on it) that watching streaming video is out of the question for now as the browser also dont support HTML5 video.

    I was at the launch event in Belgium at the Microsoft HQ and had the chance to ask a few questions. One of which was if they'll be moving to the IE9 rendering & javascript engine once it is finalized. The answer was a resounding yes. The guy also said that they are already using some parts of IE9 as well in addition to IE7 and 8.

    Does anyone know how WP7 will handle updates? I really hope they enforce updates across all the devices so you don't get stuck with old software versions months after new ones have come out like with android.
