Last Saturday i received two new SG2 to replace units that had problems from the start, about 3 months. Within a day both updated to the newest gingerbread.UVDLE ive noticed two things now, when i press and hold the power button, the phone just turns off, i dont get a menu/choice. The second thing is the lock screen. The old phones allowed me to set up a "lock screen wallpaper", when the phone when to "sleep" and i pressed the power button, the lock screen wall paper would appear and i could simply slide it out of the way to accesss the home page. I found a picture in my gallery and "set as" lock screen wallpaper. In settings/location/security/setup screen lock i get the following choices: None Pattern PIN Password I set up the pattern just to see if it works , and it does not.The phone goes to sleep and i press the power button, the home page appears, no lock screen or pattern screen to unlock the phone. Is anyone else having these issues?
