Google Nexus 5 Speaker Volume Fix Yields Impressive Results

Remember that interesting hardware mod for the  that we talked about yesterday? If not, let me refresh your memory. When XDA Elite Recognized Developer AdamOutler noticed that his Nexus 5’s internal speaker wasn’t up to snuff, he decided to investigate.

Long story short, Adam posits that the speaker performance in some units is affected by glue that has snuck its way into unintended areas. This runny glue, however, doesn’t seem to be a problem for everyone. But on some units, it makes even hearing the ringer troublesome.

After reading Adam’s instructions, XDA Senior Member Oli1122 decided to give the modification a shot. In addition to simply performing the steps, he decided to objectively measure the results. They were impressive, to say the least. After performing the modification, Oli1122 observed a 13 dB increase in sound pressure level.

For those of you who aren’t familiar with the logarithmic scale used in SPL measurement, let me put that into more understandable terms. 13 dB of SPL increase corresponds to roughly 2.46x the perceived loudness (since perceived loudness doubles with increases ranging from 6 to 10 dB, depending on frequency and loudness). In other words, this will sound more than twice as loud. Not impressive enough? Let’s consider signal amplitude. The modification resulted in 4.47x the sound pressure level on Oli1122’s device. And if you want to consider power (acoustic intensity), 13 dB equates to 19.95x the required power. In other words, to achieve the same volume level on the flawed unit, you’d have to pump nearly 20x the wattage through the speaker. If this isn’t impressive, I don’t know what is.

Now, it is important to keep in mind that your results will obviously vary. Naturally, the modification will only benefit those units with troublesome glue in the first place. In other words, if your volume is fine, don’t attempt this mod. But if you are aware of the risks and want to give this a go, make your way over to the original thread, read all the steps, and share your results. Do be careful, though. Any hardware mod is inherently risky. As good of a value as the $350 Nexus 5 is, it isn’t quite as much of a steal once you turn it into a paperweight.

Open War for Open Android: Antitrust for Cyanogen?

Android and openness is something we talk about all the time, but the recent developments in the industry point towards inherent flaws with this very premise. Be it from bloggers, political institutions or corporations, Android is seemingly not open enough. The “War on Openness” is ironically becoming an open war, where many players are increasing their stakes and scope to try and land a bigger hold - or at the very least, restrict Google’s - on what is the world’s...

What Do You Do with All of Your Old Photos?

Smartphone cameras have advanced so tremendously over the past few years that they have almost completely replaced point and shoot digital cameras for the most of us. Furthermore, since our smartphones are always with us, the majority of us end up taking tons of photos throughout the lifespan of our devices. But what happens to all the old photos you take? Do you store them on an external hard-drive or keep them backed up to an online cloud service like Flickr? Let us know what your favorite way of storing old photos is and why.

Diving into the April 2015 Material Design Update

Before the release of Android 5.0 Lollipop, the Holo Design guidelines served as the official reference for Android design, right from IceCream Sandwich to KitKat. However, updates to the guidelines were few and far between, leading to a lack of synchronization between Android design and current UI/UX trends. Google seems to have learned from their mistake the last time around, and earlier this week, a significant update was released for the Material Design guidelines, marking the second revision in less...
