They are stored in different containers that no one is able to hack, even when the phone is stolen or is lost and somebody else gets hold of it. Samsung Knox provides security for Samsung Galaxy S4 at the operating system level by allowing only authorized apps and programs to run on the device. You need to download the software and install it in your device for effective security.

You should also format your SD card, and get a new SIM card from your phone carrier. Once these things are done, make sure to install a virus protection application on your phone, and do not install anything that is not authorized and approved from the Google Play Store, or Samsung. Even then, be extremely careful with what you install.

Make sure you change all passwords too, or the person will be able to access your passwords and private data too.

Last, do not let anyone use your phone, ever. It only takes a few minutes for someone to access your phone and install a cellphone spy app. In fact, applications like mSpy and BosSpy are quick to install, leave no traces, and allow someone to remotely access everything on your phone.

Someone has committed a felony and installed a spy application on your phone by getting hold of your phone for some time. Do not touch the phone and press charges: the files contained on the phone may show who is the criminal. You also need to find the spy application itself and contact the developers who may cooperate in the case. The spy application works in a way of a spyware on your phone that sends all of your transmitted non-encrypted data to the spy server. Then, the criminal gets the data from the server delivered to his or her computer or phone.

After the case is over, you just need to hard-reset your phone or reflash your phone to use it.
