There is no doubt the demand for Google's new operating system (OS), Android L is huge. Since Google first announced the release of L back at their I/O event the tech industry has gone into hyper drive awaiting the final product. If by somehow you have missed the announcement of L then in short this is the new version of Android which is due to be released. It will be Android 5.0 (up from 4.4, KitKat) will primarily run on ART instead of dalvik and will contain support for 64 bit processors. L of course, is not the final name of the OS but without Google providing the new name (in spite of wide speculation), L is all we have to go on. Another major talking point since L's unveiling is when the OS will actually hit devices.
Most indications suggest L will be released as a final product in the fall with many believing the back end of October to be the time. This would coincide with the expected release of the new Nexus devices which are widely expected to be one of the first devices to receive the L update. However, it is clear that not all devices will receive the L update at the same time. Instead, updates will be largely based on carrier and manufacturer influence. It was recently reported that Sony's Z family of devices is likely to receive the update beginning n February 2015 through to April 2015. This is some time after L's expected release suggesting devices will vary widely in terms of updating. As mentioned, most people believe the Nexus will be one of the first devices to receive L but it also now seems that Samsung may not be that far behind the Nexus line.
According to Sammobile, both the Samsung S5 and the newly touted Galaxy Note 4 can expect L by the end of November or start of December. Sammobile lists this information based on some of their 'insiders' who have advised them of the timeframe. It is not sure how accurate the information is and there was no mention of when the rest of the Samsung family of devices will receive the update. It would be expected that the S5 and especially the Note 4 would be among the first devices to receive the update so there probably is some truth behind this timeframe. However, timeframes do change and insiders can be wrong but if you are a current S5 or soon-to-be Note 4 owner then the current news is you won't have to wait too long for L.
