For 5 stars if you could add a guide of what system apps I can mess with and ones I can't? I could pull my hair out trying to stop every pre installed app from spying on my phone  SMS  location  voice  actions ext. This no root app is a good step BUT the OS takes over and changes settings. The Android OS will change this apps settings without my permission. If you can fix this 5 stars no problem and 5 bucks!
