Iam using infinix note 4, if i don't use any app for 4 or 5 days. I don't get any notifications regarding that unused app. For Example if i don't open truecaller app for straight 3 or 4 days, it will not show caller id for unknown calls. But if i open the app after this. Caller id will be shown for unknown callers.
Please guys help me...
