Asus rolled out the Android Pie update for the ZenFone Max Pro (M1) last month, but it was only restricted to the Indian units bearing model number ZB601KL. Now, this Taiwanese phone maker has expanded the rollout of Pie globally for all the units sporting model number ZB602KL.
Asus ZenFone Max Pro (M1)
This new build carries version number 16.2017.1905.053 and weighs over 1.5GB in size. It comes with May 2019 Android security patch and fixes issues related to HD graphics option in PUBG Mobile and call waiting.
Asus is rolling out the update over-the-air in batches, and it may take at least a week or two to reach all the units. But, if you can’t wait for the update prompt to show up on your smartphone, you can try downloading the update manually by heading to the Settings > System > System updates menu.
