I have Asus Zenfone Max Pro M2 blue colour variant. From hardware point of view it is good. But it is having one of the worst software I have seen in my life. From the start it was having a lot of software issues. Full of bugs. At first it was promised by the manufacturer that frequently software updates would be given. But reality was not that. Too late software updates. And no improvement of the software with updates. Moreover the speaker quality became worst. Camera app has a lot of bugs. Asus promised to give 2 major OS updates but given only 1.
