How did this particular bit of information come about? Well, the official Facebook account of LG over in debt-ridden Greece has seen it make mention on the lack of plans to deliver Android 5.1 Lollipop to the previous generation LG flagship. In that announcement, there were no other details provided, which means that it could very well be LG working on a direct transition over to Android M for the LG G3, but that remains speculation at this point in time, so it will take some more weeks, or perhaps months, before we find out for real.
After all, time is always the great confirmer – or destroyer, of rumors.
