So, I'm replacing the battery on a tablet (title) and notice a small near the battery. Shallow, not very big, but looks like it's where the vent is
What exactly is it for?

Hello KinneyD,

My name is UnloosedCake, and I'm here to help you figure this out!
 
I found this image that appears to be the internal workings of the Galaxy Tab 4, can you describe exactly what you're referring to? I think you may have forgotten to include it in your original post between the words 'small' and 'near'... Let me know!
