Asus team failed in the development of marshmallow ,due to public demand they released the same beta version as official...they know it is a unstable version with lot of bugs,that's why they given a lollipop firmware in their official site to downgrade from marshmallow....don't expect further from Asus .....This is their Agenda...Cheap trick to end up ZenFone 2 development and promoting ZenFone 3 marketing..
