What about LG Magna H502f ? Launched in April 2015 and till now it hasn't received a single or new updates and running on Lollipop 5.0.0. :(
I think you'll find that you have forgotten the Sony Xperia z4 tablet from the list. I think it is definitely a little confusing calling the z3+ a z4 in Japan. So one phone having two names. Z3+ = z4 . Who would have known. Anyway, if one heads over to the official Sony website, click a few links, you may find yourself on this page...http://support.sonymobile.com/global-en/xperiaz4tablet/ . As one can see when scrolling down to the bottom of the page. Android 6 is coming to -the one and only- Sony Z4 Tablet. Im scanning the news on a daily basis looking for news on when the update will arrive. Be it official or unofficial. In fact, I think the unofficial may be a better choice. Im hoping the developer does not disable the multi screen button. YAY.
Anyways, just a kind reminder to add the Sony Z4 Tablet to your list, as it seems to be missing.
Anonymous, 03 Jan 2016U forgot mi3 is also getting official 6.0 supportI have not got yet
My Obi Worldphone SF1 came with Android 5.0.
Will it get an update for Android 5.1 or direct update for Android 6.0.
When will it get the update ?
GSMARENA, Z ultra gpe is not getting the update according to xperiablog and androidauthority. Not sure where you got this information. Also it's already three months since M was released, so if gpe were to get the update, it should have got it by now. Can you please clarify the source for this information?
