Anyone mess with these bottom settings under Apps?

 

[Andrew Martonik]

As the name of the Settings area would suggest, those are for developers. Things like not keeping activities and setting a process limit can be useful when testing and troubleshooting apps that you're developing and running on the device.

For the normal user, there is no reason to use these settings. You're likely to cause yourself more trouble than anything else by digging into those.
