Just a few hours ago, my ZTE blade with Cyanogen Mod 7 froze while running a wallpaper app. Initially, it brought up the error low phone memory. I still hadn't resolved this issue when it the phone became unresponsive. Now, I have to manually reboot the system by removing the battery as any other way does not work. A hard reset doesn't work either and pressing the power button does switch on the phone once it has loaded to the home screens. In fact, I can't unlock the screen. While i think that the problem may have something to do with the low phone memory, there's no way i can access it as all functions after booting the phone are not available. Please help.
