Question: I have a used iPhone 4 with 16GB of memory in it, running IOS 7.1.2. The problem with this iPhone is that the volume is really quiet whenever i'm playing music or making a call and setting the caller on the speaker.

The volume is currently at it's max (by tapping the buttons on the side).

*Note: I haven't used the "broken" iPhone for this screenshot, this was just for showing what I did to increase the volume to the max.*

I have tried rebooting the device a couple of times already, this didn't work.

What do (or can) I have to do to make the speaker play at a decent volume again? Do I have to replace it?

My issue was that I was trying to paste into an area already occupied by a textbox. It may not be obvious due to a bunch of blank lines that make the box extend longer than immediately apparent.
Be sure you are on the slide by clicking into it. The universal keyboard Command + V should pass your image. If that doesn't work then be sure you actually **have** something copied to the clipboard. 
Alternatively you can easily drag and drop an image onto a slide.
