How can there be two separate Android System under "Running services"? My Verizon LG V20 (Android 8.0) appears to be running two Android Systems at the same time, but, I'm pretty sure that isn't possible. 

Am I wrong on this or am I seeing things?  Also, the timing between the two appears off by about 4 seconds. Just seems pretty odd to me.
Technically, there is only one Android System running in your device. The other one is deceptively named by Verizon. 

If you check the process name, it starts with com.vzw.*. That package name convention can also be found in this app from Verizon. 

I'm speculating this based on the process name that it gathers data (can't say what and why) and sends it to Verizon. 

If you're concerned about that process or the corresponding package, you can disable it using adb.

adb shell pm disable-user com.vzw.qualitydatalog


Note that this may destabilize your system with factory reset left as the only fix, so proceed at your own risk and with backups already taken and stored outside the phone.
