Please add SpeakerBoost
Please add SpeakerBoost to this list. You can get it in both Google Play Store, and Amazon Market, and its free. It allows you to increase the maximum volume on your device. And, you don't have to be rooted to use it.
I found this app while searching for a way to increase the speaker volume on my tablet. It worked like a dream. Since I work in a noisy environment, I don't always hear my phone. So, I decided to try it on my One V as well. Wow! What a difference! No more missed calls or messages.
IMHO, this is one of the most important apps for any android phone.
