"0" in spare parts

[kungfuparachute]

Has anybody figured out what the 0 is under network usage in spare parts? I've found old threads but still no answer. Yesterday I got great battery life. Today 50% with 2.5 hours of mostly standby. 0 shows up with heavy network usage. What a f-ing paperweight this thing is becoming.

I would assume 4G usage if you dont have LTE in your area.

No, it's a category, not a percentage or value. I am in a 4G area. This category is my highest network usage by far.

yesterday I learned that there is a third spectrum that handles the a transition between 4G n 3G. maybe some how that is labled as category 0 ? IDK for sure thats just a hypothesis.
