To me, applications like this one are really important for school students. I bought my first significant Android the same year I began my Physics degree at my university, and immediately I realised how tremendously helpful it was. From accurate graphing applications to TI emulators (don't judge me, the real thing costs crazy amounts here!), passing through giants like Wolfram and MATLAB Mobile, there were a lot of tools for one to excel with. In fact, I'd say that without Android I wouldn't have chosen...
Make Your Own Altoids Battery Supply
If you find that your mobile device is always running out of juice before the days end then take comfort in the fact that you can always make your own emergency battery pack.
All you need are a couple of AA batteries, a couple of capacitors, a couple of resistors, circuit, USB type A female jack, a diode, a soldering kit……ok so maybe it’s not that easy! XDA forum member hockeyrcks9901 decided to have a go and follow the instructions that are widely available on the internet.
The XDA member has tweaked his battery build slightly in that it maintains a constant 5V output even as the voltage drops on the batteries. He states that it is possible to use rechargeable or alkaline batteries and apparently, it is also possible to add a third battery to further increase the capacity.
With two batteries, the set up can fit in the Altoids gum tin as per internet instructions, however the gum tin appears to be quite difficult to find and hence hockeyrcks9901 has used a regular Altoids tin. With the current set up, it is estimated that the batteries will give approximately 60-75% of a full charge.

XDA Recognized Contributor Albe95 has shared with us what looks to be Galaxy S6 applications. The ones he's provided are the GearManager, the Optical Reader, GeoNews and Kids Mode. The applications are available for download through the links in the opening post, but keep in mind it is likely that they might not be compatible with your device. There's also new information about more applications and system interface features revealed in the same thread: The alleged S6 statusbar and panel are ported to the...
Only a few years ago, it was normal for a major app release to be available for iOS but come months later to Android. That seems to no longer be the case, as Android has advanced tremendously with Google putting a huge effort into its Play Store and ecosystem. However, while the majority of major app releases are now made available for both platforms at the same time, there are a few iOS exclusives that some of us wish were on our favorite mobile OS (Hyperlapse comes to mind). Let us know which apps for the iPhone you wish were on Android.
