prompter manually counted I have 36 user apps installed, settings say there are 49. why and how?
It depends on how one counts... some things don't show up in the launcher (such as the launcher itself , but also keyboards), so there will be a mismatch if one counts things visible in the launcher and compares against the app count in Settings.
My Settings app reports 28 apps but shows me a list of 29; only 17 show up in the launcher.
