This is a really quirky trick, but it freaking works awesome.
If you simply pop off the camera in little to no light with the Maxx HD, RAZR HD, or M and let the camera flash do its own thing, the resulting blur and lack of detail is disappointing. I figured out a trick this evening to correct that issue natively in the phone. No apps needed.
You can manually keep the flash on as long as you want. This is the whole issue with the HD series camera. The components are fine, but the software doesn't keep the flash on long enough for the camera to dial in the clarity. Hopefully Jelly Bean will fix this. Here its what you do.
Turn the lights out in the room.
Assign the volume button to "capture mode" in the camera settings.
If you put the shooting mode in "night shot" it helps, but you don't have to.
Hold down on the volume button with your middle finger (if you are doing this one handed) and double tap the screen, keeping your finger on the screen with the second tap.
The flash will light up and stay on as long as you keep your finger down. This whole while you are still holding down on the volume/capture button.
I found the right exposure time to be approximately 3.5 to 4 seconds. So count to four, don't take your finger off the screen, and release the capture button.
This sounds like a lot of work, but it is really not. You are really just manually focusing and forcing the flash to stay on until the camera can lock in a better image. I took about fifty photos with this method and pulled out a detailed image almost every single time. In fact, I could zoom in on my phone and count individual hairs on my arm where there was a blurry mess before under the standard functionality.
I will get some sample photos up tomorrow.
Sorry for the delay. Here are some sample photos. The first set were all taken in the same conditions (pitch black room) using the automatic flash and letting the phone do its own thing. Notice the inherent blur in each shot, especially when zoomed in. I made the photos public and downloadable. Feel free to download the full resolution.

Now, here are some shots under the exact same conditions but manually controlling the flash.

If you download the full photos and zoom in you can really get an idea of the details that come out of manually controlling the flash.
