lol... too many mods/tweaks cause lots of un-intentional weird behaviour... sometime I do think we're messing too much with our beloved device... LOL :P

Currently there're few huge mods out there:

1. N9QuickTweak
2. Overclock Tweak
3. FasterN9

lots of these mods/tweaks "might" having some sharing system files which lead to weird issues when installing across the devices, not to mention some retail apps also having some system tweak that might as well messing each others up...

1. LPS Magic
2. Billboard
3. CalenderEvent
4. HomeScreen Setting

ish ish ish... just playing plain luck when u facing any weird issue... later we all might just gave up and reflash back the original...
