But that module (which has been full of win so far) illustrates the kinds of things that root access allows. Android users come in all shapes and sizes... some turn their phone, change a few things and pretty much leave it be (which is cool). Others obsessively pour over every configuration option and then try to dig deeper to see what else they can fiddle with. To each their own. I'm one of the latter....
If you are going to root, might as well go whole hog.... Here are some (not all) of the root-aware stuff that I've loaded.
Tasker w/ Secure Settings
I use Tasker mostly as a power manager.... turning things on and off based on the situation and need... like only flip on GPS when Google Maps or Waze needs it so some stupid weather widget doesn't ping the GPS and waste some juice. But I use it for some sound profiles (quiet at home overnight, full blast when I'm on the road, etc.)... works great. I USED to use it to manage the Google Location stuff, but NLPUnBound may eliminate that need. If you look at Tasker and your head spins (the UI is notoriously difficult to learn), try Llama.. it does most of what Tasker can do without the brutally steep learning curve.
Better Battery Stats (excellent battery usage tool)
GSAM Battery (yet another excellent battery usage tool)
Wakelock Detector (yet yet another)
can you tell I kind of obsess at times over power usage? The G3 is the first phone I've had that doesn't get on my nerves in some way when it comes to power consumption, but I still watch it like a hawk to see where I can make improvements. If you've ever asked the question "Why did my battery die so fast?" Any of these can tell you.
Root Explorer
Kernel Tweaker (Trickster Mod would work here as well)
Xposed Framework w/ the following
G3Tweakbox - Opens up a mountain of configuration options for the G3
NLPUnBound
GEL Settings - I replaced the stock launcher with Google Now, this gives you a wide variety of config options for the GN launcher.. which has, well, none
App Settings - leave the default dpi density alone and use App Settings to set the DPI scaling on a per-app basis... much cleaner and I found that reducing the system density tends to make the UI less fluid. When I reduced my Nexus 5's dpi density down, it lost some of that buttery smoothness that the phone is famous for.... not drastically so, but App Settings allows me to set the DPI density lower only for apps that I want to 'shrink', like GMail... without affecting the entire system.
