Hi, I own a Samsung Galaxy S not rooted. I would like to have a iphone style unlock screen where I can put a wallpaper of my sons. I have tested lockbot and it does not work propertly. When a missed call or a sms arrives it returns to original samsung unlock screen. I have also test nunlock and lock 2.0 and all they have issues with my phone. Does anybody knows of a app that work correctly? I only want the slide bar and a photo..... it is not so complicated. What I have seen is that operating system is replacing the unlock app to original one each time an event happen, so I intuit maybe this a general problem that apps cant not deal with. thanks.
