I have received a new software / firmware OTA update for my Asus Zenfone Max Pro M1 which enabled VoLTE on Airtel, Vodafone, Idea Mobile Operators in India. This update also added the VoLTE for DTAC in Thailand, Smartfren in Indonesia, Megafone & MTS in Russia.
Asus also added the VoWIFI for MTS in Russia. According to the update description, this update also improved the fingerprint scanner unlocking speed, added 1st May 2018 Android Security patch & improved the camera performance. Lets find out this update in detail.

Let me know your comments and if you also own Asus Zenfone Max Pro M1 then do share your experience post this update. :)
