Video shows how LG developed its multitasking tool, QSlide
The QSlide feature on the LG Optimus G is a multitasker's best friend. Unlike the multiwindow function on the Samsung GALAXY Note II, which lets you cut the screen in half to use two apps at the same time, QSlide doesn't require the user to use the apps in a cramped space on the screen. With QSlide, two apps are using the device's 4.7 inch screen at once and one or the other app becomes translucent by sliding the QSlide controls. Controlling the level of translucency for each app, the user can watch a video while composing email, send a text while browsing the web, or do any type of multitasking while still using the full 4.7 inch display.

It's a brilliant idea and the story of how it was discovered makes you realize that inspiration can come anywhere, from anything or anybody. While LG's Senior Research Engineer Sebastian Hochan Song was driving in a car with his younger sister and nephew, the windows on the car fogged up. Watching his nephew draw on the fogged-up window from the rear-view mirror, it looked to Song as though his nephew was drawing on a transparent layer over the background of the outside. It was as though he was drawing on two layers and the engineer could see both of them at the same time. With this, QSlide was born.

While LG was able to make the second layer appear right away, controlling the level of translucency was difficult, according to Song. But the concept has been perfected and it is now one of the new features on the LG Optimus G.

Mate at least they are trying something new. And It is always good to appreciate something new in technology if you belong to a tech field.

I'm not trying to be overly critic, but all I see are gimmicks, not a real improvement in multitasking field, something that I realy need in android. Maybe I'm just asking to much from smartphones...

Dude, like Jelly Bean here said, learn to appreciate something new. It might not be useful for you...but doesn't mean it will be useless for others as well. Inspirations come from everywhere, if you know just where to find it, you'll get it right.

True, this is far from the awesome multitasking experience of my GNOTE II. But well, at least they're trying something new.

It will still have the feature that it will run two full apps side by side. This is another way to multitasking on the device.

They are definitely on the right track. Give'em a half a year or so and a couple of handsets later I think LG can pull out a real winner! of course this phone is pretty cool too!

And this phone looks way much better than ip4. With no ugly curves, with sharp edges.

Something that might appear useless for you could world a million for others. When you keep that in mind, you might start learning to respect and earn some respect too.

Samsung and LG has taken multitasking to a whole new level in Android platform. I believe they should patent their features. And I hope Apple would learn something from them and will bring some sort of customization in its platform as well.

Why must you mention Apple?

Because that is the only platform in mobile OS which doesn't allow customization :)

apple has many multitasking patents..... they also have patents for dynamic icons(icons similar to wp live tiles) they also have patents for stuff like widgets, etc etc .......but they don't want to use those patents straight away because they want to make them more easier and user friendly....they can afford to do that because they have their own OS android OEMs like to push all their new inventions and patented features because if they wait for some time, then they may lose their market share to the other OEMs that causes some problems but its always good to have more features.... personally, i believe that both the worlds have their own advantages and disadvantages i would like to have a galaxy s3 and the ipad( the bigger 3rd gen ipad)........ios for the apps, security and for the overall experience(stability, smoothness, refined ui)......galaxy s3 for its features, bigger screen and comparatively cheaper price with expandable memory and removable battery(build quality of the s3 isn't good buy that's okay with me) i have typed such a long comment because these ios vs android fights and comparisons are quite boring....the truth is that neither of the operating systems is as good as both the operating systems together with you.... you can do the same thing with the pcs, just get and mac and dual boot it with windows, life is always better when you try different things.....

no actually, i like the mac os x and a retina display, so i would prefer the new macbook pro and dual boot it with windows........

why should they patent it, if it is a great feature why not share it, i know people want to keep their new ideas and creativity for themselves and sue others who try to copy it, but the world would be a better place if people allowed sharing of ideas and building upon them to create a better society, and yes they may lose the uniqueness in doing so losing out to being rich, but money shouldn't be the reason to stop helping.... I like some of Samsung features, such as the double window ability on the Note 2, obviously its already been done by windows, bit this is the feature i most admire on a mobile platform, this feature with a little bit more improvement will definitely make life easier by allowing true multitasking abilities on a smartphone... don't block other companies from building upon this, let the idea be free...

because every company doesn't think like that, if lg doesn't patent this, then the other companies will use this feature but they won't allow lg to use their features, then lg have nothing to show in their devices........google is already giving the android os to everyone for free, so let the OEMs do something on their own and try to make themselves look better than their rivals who make products running on the same os

This is the real game, fighting with technology rather than stupid patents. I'm not mentioning any one here.. :P

I am using the galaxy note 2 and i find the multiwindow function note a gimmick like siri or svoice.i practically use the feature every single day.spen is also not a gimmick.i cant use my note 2 without the spen.i find myself using it for a lot of stuffs.not that am a samsung funboy but note 2 is practically the fastest and most feature packed android smartphone i have ever used.this idea will also be practical depending on how you learn to use it in real life situations.bigups to lg.

Well... i dont like this multitasking... is kind of confusing... you cant appreciate or control whats in the background. I think is far interesting the way Samsung does it on the Note 2. You can control both applications, and resize them... is a better approach.
