There are different applications that can use. I believe Lookout is one application available on Google Play. It's a security application, I think it is both anti-virus, and allows you to track the phone. You might want to double check because some of the features might only be if you purchase the premium version of the application. I'm sure there are some other free alternatives. You can search Google Play, there are many different applications available and there are probably a lot that do what you need it to do.

I got a brand new HTC ONE. In case when the phone is Loss/Steal, is there any way to track the location of the phone? Please let me know if there is any software any tools which can help me.
