What's the difference between Camera.apk and com.sec.android.app.camera.apk? I'm trying to install a modified version of the Camera app on my rooted Samsung Galaxy S (Captivate) through copying to /system/app and through installing a zip file via ClockWorkRecovery.  It doesn't seem to be working (based on the fact that the modified camera should have no geotagging).  

Looking in my /system/app/ folder I have Camera.apk and com.sec.android.app.camera.apk.  Are these complementary files or are they different camera app files?  Camera.apk has a timestamp of August 1, 2008 (which doesn't seem right) and the other has a timestamp of August 1, 2011 (which is around the time I was playing around with this stuff).
The Serendipity ROM only contains Camera.apk and CameraFirmware.apk.  I would think that the version you're trying to copy over is being renamed by the system on reboot and the original Camera.apk is being restored.

What I would try:


Get the non-CWM version of the Camera.apk and put it on your SD card
On your phone, use Root Explorer or similar to mount /system/app/ as RW
Rename /system/app/Camera.apk to Camera.bak or something
Copy in the new apk from the SD card
Remount /system/app/ as RO, you may want to make sure /system/ is RO as well
Try to use the camera.  If it works, reboot and see if it still works.
