Display backlight flickers when brightness setto Automatic on 1520

When ever I'm a low lit room or in pitch dark outside I of coarse set display brightness to automatic so I don't have a bright screen blaring in my face .Anyways when my phone is on this setting in the dark I've notice the l screen flickers its quite irritating and distracting Is this normal, does anyone have a 1520 with this same issue or is it just me.I have only had this phone since June so its still pretty new .
