Again, "I'm loading apps not dependent on google", "I never had this issue on my previous Blackview mobiles". Why do disabled apps with disabled notifications still spam notifications and how to I silence them for good.
Google Play Services is one of the worst things around.
It is literally tied to everything on a device, and so is the most nefarious spyware in the Google arsenal.
Those messages are not coming from Google Play Services.
They are coming from any number of system apps that monitor whether or not Google Pkay Services is running.
l even have seen devices that will continuously disable the Wi-Fi if Google Play Services is disabled.
"Wi-Fi Manager requires Google Play Services to function"
Funny, because the Wi-Fi works just fine without the stupid 'Wi-Fi Manager', which obviously only exists to ensure that Google Play Services is running.
Here is my solution- use a firewall.
Leave Google Play Services running, but block internet access for it.

Disable whatever Google crap you can, and block whatever you can't.
I block apps I have disabled as well, because that is how much I trust Google.
The firewall operates via the VPN api on Android, and only allows internet access to what you choose.
Only one app can access the VPN api at a time on a single device.
However, you can set up more than one profile on a single device, and run a separate VPN api on each.
