S3 T999 Missing SMD Component Near Power Button Switch

While taking apart a Samsung S3 T999 to repair a power button switch I noticed that it had 4 solder pads with traces coming from the switch. Upon further inspection, I realized it was missing either a resistor or diode on two of the pads. I was wondering if someone could help identify the part and its value so that I may replace it. I have tried to find schematics for this particular model with no luck.

So, on the functional board, did it have two surface mount parts? In the picture, it looks like two of the pads didn't have solder on them at all. Only the one set of pads was populated.

After getting ahold of another board of the same model, I found that the missing component is a 10k 0402 package resistor. Replaced with new resistor and now have a working s3 power button.
