I almost give up. I tried many many things but my samsung s23 is killing important apps and I miss notifications. As soon as I unlock my phone, all of them showing up instantly. I'm missing messages and important notifications. I'm constantly checking phone because of it. BTW, it's working sometimes I don't know how and when it decides to kill my apps. I disabled any memory and battery related optimizations and mark my important apps as unrestricted and never sleep but it doesn't work mostly
EDIT: it's definitely duckduckgo app tracker. It somehow kills some apps. Disabled it and all of my issues are gone away
Will leave this post up but just a heads up on rule 2 in the sidebar. Tech support and other questions related to Android are welcome at !askandroid@lemdro.id. Thanks!
Do this. If you don't want to start from scratch you can reset all permissions in the settings somewhere, but that means you'll have to re-grant permissions again. It is possible that there is an app installed that is "managing" things.
Starting from stratch will take huge amounts of time, configs and other things , is it really the only way. Im using android for 2 months and i just installed my apps.
I don't have a Samsung, but check your apps (maybe system apps?) and look for "Google Services Framework" and "Google Play Services". See if you can disable any optimisations and clean the app data. Reboot and then open the Play Store - which might not work well right away - but will force Services Framework to "reload". Reboot again after a minute or so and see if the problem has improved. I'd also try to remove and re-add your Google account.
One of these (Play Services/Services Framework) handle the "cloud notifications" used for push notifications.
