I wonder if there is something like a graph or diagram that shows the different parts that comform a distro.

Like a visual aid where you can see what combination of parts or components you are choosing on a distro.

Does something like this exist?

At least for me, Play Store impulsively updates itself. I would even say that some apps got updated even though I’d disabled auto updates.

I installed Aurora and disabled Play Store altogether. So I update apps manually whenever I want to.

The only SD card that ever failed on me was a barely used Lexar I bought for my camera. And it was not because it bent or anything.
