Google Android L developer preview is available for Nexus 5 and Nexus 7 users, but from latest details it seems final version of Android L is just few weeks away. So far only HTC claimed that they will be releasing Android L after three months of Google release. Recently HTC well known tipster LlabTooFeR replied a tweet about when HTC will be releasing Android L update for Butterfly S. They replied HTC will be releasing Android L within three to four months.
As I mentioned above HTC already claimed that they will be releasing Android L after three months of Google official launch, if HTC is going to release Android L in four months, it clearly indicates that Google most probably will be releasing its Android L operating system sometime in October 2014.
On the other hand, we have plenty of details suggesting Google and HTC are in joint venture for manufacturing of upcoming Nexus 8/9 Tab. In case if these rumours are accurate, then we can HTC will be rolling out Android L at much shorter time frame than expected by HTC customers. Initially only HTC confirmed they will be rolling out Android but recently LG also confirmed that they will be rolling out Android L as well.
