iphone 4 - not dimming timing out ?

[foreveraudio]

has anyone ran into this, i have iphone 4 , jb with lime unlocked.
i notice randomly when i do something on the phone and then set it down the screen never dims then turns off like it suppose to
it just stays on unless i hit sleep button
it used to do this after jb , but then i noticed when i uninstalled supreme pref 3.0 it stopped doing it. thought i had it fixed but now its doing it again and i havent added anything ?
just curious
thanks

You said you haven't "added" anything but to clarify, you have NOTHING from cydia on your phone besides Cysia itself?

If you had ScreenDimmer, I could see why it stays on as there is a setting for that.

no the only thin i added from cydia was supreme prefrences but uninstalled that and noticed the problem stopped but now its doing it again, i have noticed it only seems to do it after it comes off the charge though
