Hello and welcome aboard. Thanks for joining the community.
Make sure to use the FB for Android available on the Google Play market. Then do this: on your profile page, tap the word photo (right beside the word status), and then upload photo. This is assuming you are using the new FB timeline. I'm sure it will work if you're still using the older FB page.
I hope this helps. Also, you can check-in to your device's area of support for some great tips & tricks on your device.
