com.osp.app.signin is an Android package file found on Samsung devices, its exact functionality is unknown, but we know it’s a part of the Samsung account app and related to account sign in. Samsung account is a membership service that allows users to use multiple Samsung services on devices like smartphones, tablets, TVs etc. Package files like these have created a lot of confusion among people; some think they are secret apps used for cheating, some think they are Bloatware and Spyware.
