people find silly on why I am using BB classic with OS 10 in 2021, because it is outdated. I bought this due to dual functionality(best in touch and type + security). My question is even when it supports android apps like whatsapp. I am not receiving the whatsapp notification (audio or video call or messages) at the right time when the phone display is OFF. There is some lag in delivering notifications. It works only when the app is opened initially. When I am referring to the forum, enable permissions is they what telling. But, i enabled it also. Still I am not getting notifications at the right time.
