Abstract: Today is the world of smart phones. Almost everyone now uses smart phones. A large amount of data is communicated via these smart phones. These smart phones save some of the user’s data without the knowledge of the user. These data can be analysed and can be used into different things which can show the behaviour of the person who owns the smart phones. This survey study, basically deals with some of the different types of data that is collected by the smart phones and can be used in such a way that is useful for the user of the smart phones. I have surveyed some papers on human activity recognition with smart phones and will use the phone data to analyse the reactions of user for some applications that are installed in the smart phone.
