spy experience
 

f you have the money, I'd say buy a new phone and find a new boyfriend. If you cannot get a new phone then take it to a repair shop or contact the manufacturer. Samsung and Apple both have responsive customer service. If they cannot help ask for advice on what to do. Do you have any tech savvy friends to ask for help? If your bf is in the technology feild and you can prove he did this then take it to his employer and ask if they have any way to check the phone because their employee violated your privacy. If it cannot be done and the Spyware is still there then contact non emergency law enforcement or start to use new app https://cellspyapps.org/
