Android 5.0 Key Lime Pie—the next iteration of Google's mobile operating system—is expected to be released before the end of the year, but beyond its expected release date, very little information is actually known. Android 5.0 Key Lime Pie will pick up where Android 4.1 Jelly Bean left off, meaning that the operating system will be smoother, sleeker and more capable than ever before. Thanks to a slew of ultra-powerful Android phones hitting the market, Android 5.0 Key Lime Pie will likely be the most feature-heavy version of Android to date.

Although there are plenty of uncertainties surrounding the release of Android 5.0 Key Lime Pie, many analysts, technologists and other close to the matter are beginning to predict the most likely additions to the Android operating system. Among the many Android 5.0 Key Lime Pie rumors are speculation about what features will be added, what phone the operating system will be released on and what new design elements may or may not be added. We can't report with any certainty about anything involving Android 5.0, but we can say that there are several . Here are the top three things to know about Android 5.0 Key Lime Pie:

1) Android 5.0 Key Lime Pie Release Date: The next iteration of Android is expected to be revealed at Google I/O 2013. For the uninitiated, Google I/O is the annual developer conference held by Google where the company promotes platforms such as Android, Chrome, Google APIs, Google Web Toolkit, App Engine and more. Google I/O is scheduled to take place on May 15-17, and it's expected to showcase a variety of big announcements from Google including new features in Google Chrome OS, Google Chrome web browser and even Google Glass. It's unclear which, if any, platform will be the central focus of the conference, but if it's anything like Google I/O 2012, Google will likely push Android 5.0 Key Lime Pie to the center of the stage.

2) Android 5.0 Key Lime Pie Specs: The features and specifications surrounding the next iteration of Android are a little murky, but there are certainly plenty of speculations to choose from. Android 5.0 features vary depending on the sites that you visit, but most technology journalists and Android developers appear to agree on a few things. The first is that the default Android keyboard is significantly less responsive and worse than the keyboard on iOS. There are plenty of third-party apps that solve Android's keyboard problem in the short term, but most experts tend to agree that Google will need to make significant improvements to the default keyboard moving forward. The consensus on Android 5.0 Key Lime Pie keyboard expectations seems to be that the keyboard will be somethign between Swype and Swiftkey. Most users believe that there will be better word suggestions given by the operating system, and there's a strong possibility that Google will incorporate some version of the swipe-typing feature.

Android 5.0 Key Lime Pie is also expected to include Android's first video conferencing software built by Google. For several years, Apple has allowed users to make video conference calls on the iPhone using Facetime, the company's own video conferencing software. Although Android users have been able to make video conferencing phone calls for several years using third-party apps, most experts expect Google to finally release a video conferencing apps of its own. The demand for video conferencing capabilities is only expected to grow as internet speeds increase and smartphones get stronger. Blackberry 10 and Windows Phone 8 have video conferencing software already baked into the smartphones, so it's only a matter of time before Google includes the feature in its operating system.

Android 5.0 Key Lime Pie is also expected to be easier to customize than any iteration of Android that has come before it. Google has frequently co-opted features included in third-party versions of Android and other popular apps. When Android 5.0 is released, it's likely that the new operating system will include customizable navigations bars and commands at each edge of the screen. Know Your Mobile notes that Android 4.2 allows users to slightly modify the number of homescreens available, but most other launcher applications allow users to do more customization.

3) Android 5.0 Launch Phones: One of the biggest secrets surrounding Android 5.0 Key Lime Pie is what phones or other mobile devices Google will incorporate into the release of the new operating system. Last year, Google famously announced the Nexus 4 smartphone, Nexus 7 tablet, Nexus 10 tablet and the Nexus Q during Google I/O 2012. The announcements were some of the largest and most-hyped in the history of the event, and this year probably won't be much different. Experts and analysts have essentially boiled down the possibilities to two different devices. Android 5.0 Key Lime Pie is most likely going to launch on a device called the Motorola X Phone or the LG Nexus 5.

The Motorola X Phone is shrouded in secrecy largely because it will be the first major release from Motorola Mobility since the company was purchased by Google for $12.5 billion. The phone has been rumored to be built from the ground up and is expected to be Google's answer to the iPhone. "According to [Smarthouse sources], who claim to have spoken with Telstra CTO Hugh Bradlow on the matter, the X Phone will be a 'game changer.' It's supposed to be a 'real breakthrough' that will put pressure on Samsung and Apple, something no one in the smartphone industry has done in a couple of years," reported Kellex of Droid Life, the popular blog dedicated to Android rumors and news.

The Nexus 5 is less likely to be released at Google I/O as a launch device with Android 5.0 Key Lime Pie, but there's still a small chance that it will roll out along with other devices at the conference. Here's what Android and Me says about Nexus 5 specs:

5.2″ OLED Display with 1920×1080 resolution

Qualcomm Snapdragon 800 @ 2.3 GHz


16/32/64GB of internal storage

16MP rear camera by OmniVision (4k video recording @30FPS, 1080p video recording @60FPS, Real Time HDR & HDR video recording, optical image stabilization, BSI 2.0)

Android 5.0 Key Lime Pie features, rumors and other information about the next generation operating system that are circulating the Internet are hard to sift through, but, we assume that—as has been the case with most other major releases in the past year—the information that's currently available about the device is most likely fairly accurate. It remains to be seen whether the Android 5.0 Key Lime Pie release date will coincide with Google I/O, but quite frankly, we can't think of a better place for Google to usher in the next version of its flagship mobile platform. As for the Android 5.0 Key Lime Pie features, we'll just have to wait for the official release to see what the new operating system looks and feels like.
