Hihi, isit everytime got notifications not coming in or delayed notifications?Last time I used OPPO phone also these 2 issues so abit scared now.
If Mate 9 really has these kind of issues, then I may reconsider buying.
Did some try and error for the above issue.
Such issues will occur if we clear cache or ram through the phone manager.
It forcibly closes the app and that is when the notification stops appearing.
If we close it normally, ie pressing home button or swiping opened apps, the notification will still appear.
Worse case scenario is when we clear the ram/cache/memory and manually reopen whatsapp/telegram/messenger.
