After a recent phone update (which took too long due to "too many apps") I saw the total apps updated was over 700. I only have 69 apps on my phone. Why the discrepancy? What does my android phone consider an "app"? Can I delete these others?
69 normally visible apps don't account for all the system apps/packages/functions.
If you run an app like CCleaner you can easily see, using the app manager section, what all the apps on your phone are. Most of them will be locked and you can not remove them, as without root you can't generally touch system apps.
