Can Anyone With A Smart Phone Bug Your Phone

No. The only way for anyone to spy on your phone or location, is if they have had physical access to your phone and installed an app to track you or your activity on your phone. And you know who has access to your phone and who doesn't, and can check the files and apps that are on it to ensure it is safe. Some smart phones will send the smart phone user a report saying a text they sent from their smart phone, to your phone, was recieved, with the time it was received, which might tell them when you opened the text, but that is the limited amount of bugging they could possibly do. If you have your phone GPS enaabled and use an app that let's people in your social network or the public in general, see your current location, and you don't wish them to, then deny access to that social app and delete your information from it and/or disable GPS. Nobody can trace your phone using GPS without your permission, except the authorities so don't worry.
