Hi! First of all in user's guide manual says that this tablet works just fine with only 3 IM : 1.Google Talk; 2. Windows Live Messanger 3. Yahoo! Messanger. Try one of those to see if the camera button appears.
However, if you need more information you can find them here: ( http://www.userguidemanual.com/samsung-galaxy-tab-gt-p1000-tablet-manual-user-guide-french-english/ ). *This link allouds you to read and download free user's guide manual (in PDF format).
I hope this will work! Have a nice day!

This hard reset can be done even if the device won't seem to power on.

1. Make sure that it is OFF.
2. Press the Volume Up and Power button simultaneously and hold them for few seconds.
3. When you see the logo appear, release the Power button (but keep holding the Volume Up button).
4. Next you'll see a menu where you can use the Volume Up & Volume Down buttons to navigate across. Check the option labeled as Wipe Data / Factory Reset using the Power button.
