Asus has never been too fast to update its devices with BIOS/firmware or drivers, so seeing that none of its handsets got Android 6.0 so far is no surprise. However, the Android 6.0 Marshmallow update for Asus smartphones and phablets is still in the making and will eventually arrive by the end of Q2.
Back in November, Asus unveiled a list of devices expected to receive Android M. Back then, no timeline was revealed. Now, that information is finally available. Unfortunately, it does not look great, since the wait is far from over. According to an official post on the ZenTalk forum, the Android 6.0 upgrade will hit the following devices: PadFone S, ZenFone 2/Deluxe/Laser, ZenFone Selfie/Max/Zoom. The date is not accurate, but "Q2 0f 2016" should be enough for now.
The good news is that three ZenUI apps will disappear, Asus Messenger, Mail, and Calendar being replaced by Google Messenger, Calendar, and Gmail as the defaults. To get rid of Asus' apps, one needs to restore to factory settings after the update. Unfortunately, there are more than three months left until anyone will be able to do that, but we will keep you posted.
