This coral has some brown on it

Is this normal or do I need to take action immediately? Best my phone can do.

Idk is this better?

Yes bubble algae. See if you can remove whole or scrape it off.

Might be a good idea to do an iodine dip also

Just looks like a dead spot to me but tough to tell from those pics. Do you see skeleton? If so, it will likely heal over on its own eventually.

Be careful removing the bubble algae. If it ruptures, you will release spores all over the tank. I would remove the entire frag and place it in a cup of tank water. THEN clean off the algae. After, rinse it off in a fresh cup of tank water and place it back in the tank.
