I just disabled Google Play Services on my Android phone to increase privacy... then I started to get spammed with about 10 notifications every 10 seconds (not a joke) to tell me that those 10 apps would not work properly without Google Play Services enabled even if they did work properly... Google and/or LG allowed me to disable 7 of these apps, but the others could not be uninstalled or disabled using the GUI... I had to use ADB to remove them. One of those apps, believe it or not was the LG phone clock and another was the calculator.

After I removed all apps that were complaining about missing Google Play Services and installed alternatives for the ones that I needed like the calculator, everything was working fine. (thanks to f-droid for helping me find viable alternatives)
