It seems that Asus is planning to bring the updates to its Asus Zenfone Max Pro M1 (Review) and the Asus Zenfone Max (M1) as two new devices have been spotted getting certification from Eurasian Economic Commission (EEC) in Russia. The listing reveals some information about the upcoming smartphones like their names, model numbers and operating systems. As per the document published on October 5, the Asus Zenfone Max M2 will be referred to as the ZB633KL with the Zenfone Max Pro M2 will bear a model number of ZB631KL. When it comes to the operating system, the listing mentions that both the devices will ship with “Android version 8 pre-installed” although there is no information if the OS version is Android 8.0 or Android 8.1.
