Lock screen Problem. SGS3 GT-I9305

[alphonsus2010]

Sometimes when i press the power button to turn on the screen, the first thing i see is a purple/pink screen, then it turns black then my lockscreen comes on. This happens very rarely and it has only occured for less than 6 times since i bought the phone. This purple/pink screen appears and changes to black screen, followed by my lockscreen coming on, it all happens in one second or less. Any ideas?

Are you rooted or unrooted? If rooted, are you running a custom ROM?
