As I have a 5Z, not only a 7 Pro, had n the past also 4 and a 6 - I am aware about the limitations for an extended software updates support, I went through that in the past with the ZenFone 4, where and when the OS upgrade to the latest was faulty, but also sometimes the Android OS it is not changing significantly from a year to another, some really major changes could be seen after 2 or 3 years and sometimes aren't so demanding considering the hardware. Anyways, it would be great if the support can be extended. Cheers!
