Android 4.4 had an extra little goodie we were not expecting until a leaked rumor told us that the new launcher for the OS would be called the Google Experience Launcher. Since then, the apk leaked out for anyone to use, but then we wondered if Google would just release the launcher in the Play Store. Well according to a new report, no they will not be doing this anytime soon.
Google tells us that the new Launcher on the Nexus 5 is exclusive to the phone — though the company may change its mind and offer it for the Nexus 4 and perhaps even put it on the Play store someday. For now, Google wants to see how users take to the Launcher on Nexus 5 before it offers it on other devices.
Android Police dug deep into the launcher and found out that most of its functionality is based within the Search app. That would make it easy for Google to release the whole launcher for various devices, with a couple features not being able to get utilized , like the touchless voice controls. It really does not matter much since the apk has leaked out, and some have even said their device was able to use the touchless voice commands with the launcher. It would not surprise me if Google eventually released the launcher in the Play Store, since they have been steadily releasing their apps to the Play Store. Only a matter of time I guess. et us know what you think about this.
