I have an original motorola droid. I keep the phone "unlocked" without a screenlock password. I know she keeps taking my phone and looking through it by all the fingerprints on the screen after I've wiped it clean. Want to call her out and catch her and prove to her she's doing it. Is there an app or anything that could track times that apps have been opened or anything that could be solid proof she's looking through it? If I lock the screen, then I get accused of hiding something. I leave it unlocked cause I have nothing to hide. Really don't even care that she's looking through it, the problem is that she will deny it all the time... Any help or suggestions?
