Look, I am never, ever ever going to use Docs, Sheets and Slides on my LG K7 (running 5.1.1), but I have come to terms with the fact that there is no way to remove them from my phone without rooting, which I am not interested in doing. But I figure at least I can free up scarce storage space by erasing the apps' data, which typically is on the order of about 70 MB each. Liberating 200+ MB of available space on a phone that only has 4GB internal storage, 3/4 of which is taken up with the OS and apps that can't be removed: it means the difference between "Not enough space to update apps" / "Voicemails will not be downloaded" and normal operation.
But every time I clear this memory -- without fail -- I find that within 24 hours the data is recreated and I am right back where I started. Note that I'm not using Docs, Sheets or Slides during this 24 hour period, so the apps are not running. Why does this data keep getting recreated, and is there anything I can do to stop it?
