ASUS as a huge company they should know how to manage their products by providing fair and equal updates, no matter for an old product or newer ones. For example, Oneplus are really good in providing updates for their products, even after releasing their OP7/Pro they still manage to provide some new useful feature updates regularly for their OP6T. As a customer of your product, we do understand the company needs to prioritize on the new product line (Zenfone 6/Asus 6z) but please do also manage your old products (Zenfone 5z/Asus 5z) by giving some new feature updates. We hope to receive some new feature updates soon for our Zenfone 5z/Asus 5z from the developers working hard at ASUS. All we wanted is some new feature updates for our so-called 2018 Flagship.
