I bought an S3 i9300 as a business phone, and I'm having problems with the lock screen. Running 4.3 stock. The first thing is that it takes between 2 and 3 seconds for the screen to wake when I press the Home or Power buttons. This is considerably slower than my everyday-use iPhone 4S, which takes about 1 second. I don't know any other S3 owners, but this delay doesn't appear to be normal. I'm using a PIN lock screen. I tried disabling the personal message, but it didn't help. Any ideas? Also, I can't seem to find a way to access the camera from Lock screen. It looks like the ability to use Swipe and PIN unlock together was removed between 4.1.2 and 4.3. Anyone able to help me out here?
