Help identifying component or Samsung galaxy note 2 schematic

[zakkos]

Hello everybody,
a friend of mine is repairing a samsung galaxy note 2 and has some trouble identifying a broken component.
It has 4 pins plus a central one which i suppose is ground plus anchorage, smd with an almost cubic package. It's marked 8LU4 in a 2x2 fashion (8L on top and U4 below) and a simple search on google and various IC finding sites didn't end up with something useful. Right next to the broken component looks like there is another one of the same kind marked S5EX (as you can see in the picture). Can someone help me identifying those components? Alternatively are schematics of this phone available (again a google search returned no results...) to track the component down?
Thank you in advance!

Thank you very very much. I asked my friend for more photos and info about where the component is placed. I also gave him the link you provided. Unfortunately i have to wait for him to take the pictures. Although i hope the service manual is enough for him to track the component.

Here I am again, my friend gave me the pictures of the component and a larger view comprising the whole board. Thanks.

Just a guess, these could be the Bluetooth IC crystal and output filters. They are the only 2 four pin devices in the phone and their wiring configuration seems to match the schematic.

thanks brian, but aren't they 5 pins components? with one (another ground i suppose) underneath the IC itself? or it's not to be considered as a "pin"? This is also a question for my own understanding!
