I am developing an Android app whose main use is to be notified instantly of certain events.
I have a Huawei phone.
The app works well with FCM
I receive notifications in foreground and background, from FCM console and also from my server (PHP code)
The problem is:
- I put my phone in ultra power saving mode.
- After that I send a notification. FCM return success operation.
- Finally I change my phone back to normal mode
- I Never receive the notification. Not even if I open my app.
I already check my app in "Protected Apps"
I want to know how to fix this issue. It's an Android bug? It is only a problem of this device? I mean... I do not think my code is wrong... the problem is how the OS manage FCM, google play services or whatever... there is a solution? OR an alternative cloud message service that works well? Other apps like Whatsapp doesn't have this problem.
Thanks in advance
