ZenFone 4 Pro Android 9 Pie update

  • Android Pie eligible
  • OTA update release date expected in Q2 2019

Asus ZenFone 4 Pro the premium offering in the ZenFone 4 series and as such is entitled to at least two major OS upgrades. Android 8.0 Oreo is already in the past, making an update to Android 9 Pie the next in line.

Given that the ZenFone 3 series started receiving the second major OS upgrade (Oreo) in late January 2018, we expect a nearly similar release date for the ZenFone 4 Pro Android 9 Pie update, although this is just us making an educated guess.
