Android Central Question
As of last Friday evening, my Galaxy S8 started having problems with notifications when it's connected to wifi. Until yesterday, it wouldn't push any notifications for any app unless I specifically opened the app. For example if I was looking at WhatsApp, I wouldn't get any Facebook messages. As of now, that only happens if my screen is turned off. For example, I go to WhatsApp web, and it tries to load. While the screen is off, it is stuck at almost the end of the loading bar. As soon as I wake my screen up without even unlocking, the loading bar completes and the interface loads. This happens with apps including but not limited to Whatsapp, Facebook Messenger, Signal, Facebook, Gmail, and Google Play Store. For example, while updating apps on Play Store, turning off the screen causes updating to stop and play store to give connectivity error messages. There isn't any problem if I am connected to mobile data.
Things I did in vain to resolve this issue:
Restart phone
Turn phone off and start again
Reset network settings
Turn off smart network switch
Turn off enhanced LTE settings
Set WhatsApp notification priority to on
Update WhatsApp
Turn off power monitor in battery settings altogether
Reset app preferences
Turn airplane mode on and off
Set time to wrong time, kill all apps, and change the time back to automatic
Turn off nearby device scanning
Current relevant settings:
Apps > Special Access > Optimize battery usage > All mentioned apps are off
Battery > Power monitor > Unmonitored Apps > Facebook, Messenger, Signal, Whatsapp --- Gmail and Play Store cannot be added
Battery > Power monitor > Always sleeping apps > 0 apps
Battery > Power monitor > Sleeping apps > None of the mentioned apps
