How can i check my Samsung Galaxy J7 Prime MB is changed or not?
Last week I visited a Samsung Authorised Service Centre in Bangalore. As per their diagnosis, they changed my phone's MB,battery and something else. But surprisingly I found an app which was installed on my old MB in my new system. How come it is possible as i the same app is not available in appstore aince 6+ months. How come this is possible? Can somebody help?
