Using "pm setInstallLocation" to free up phone storage

If you are running Android 2.2 and above, there is a simple way to free up more phone storage without rooting the device.

First you need to download and install the Android SDK. Now this is not as scary as it sounds. It is actually a pretty standard installer, and it will come it handy later if you plan on doing more hacking on your Android device. The reason for installing the Android SDK is to use a command-line utility in the SDK called "adb".

Next you need to download and install the USB driver for your device. If you using an Android device from one of the major manufacturers, this page should help you locate the driver.

Now select "Settings" on your Android device, then "Applications", then "Development", then make sure "USB debugging" is checked. After you have done that, plug the device into the USB port on your computer and make sure all necessary drivers are properly installed.

Open a command prompt and "cd" to the Android SDK folder. Then type "adb devices":

> cd \android-sdk-windows\platform-tools
> adb devices

You should see your device in the list of attached devices. If not, the USB driver for your device is not properly installed.

Now, issue this command:

> adb shell pm setInstallLocation 2

This lets you move applications that do not have A2SD support to external storage. The usual caveats apply i.e. you should not attempt to move widgets, input methods, live wallpapers etc. to the SD card. And system apps like Google Map etc. cannot be moved. But otherwise, eveything else is game, and you can free up quite a bit of phone storage by moving previously unmovable apps. In addition, every app you install from now on will go automatically to external storage (some of which you may have to manually move back to phone storage).

The nice thing about this method is you can easily revert the changes by issuing:

> adb shell pm setInstallLocation 0

The permissible values are:

0 - auto (default; OS decides where to install)
1 - force internal (forces apps to install on phone storage)
2 - force external (forces apps to install on external storage)

In fact, if your phone is already rooted, there is a free app called Move2SD Enabler in the market that does this in a nice GUI.

The limitation to this approach is that you are constrained by what you can move. Android's native A2SD only move application files, not library and data files, so some phone storage will still be used. However, for most users, this approach should free up enough phone storage with a minimum of fuss and complexity.

Cooling mod for the X96 Air #2

Previously, I added a USB cooling fan to the X96 Air TV box . The problem with this mod is that the fan is always running, and it runs at full speed. Ideally, the fan should kick in only when the CPU temperature is above a certain threshold. It would be even better if there is a way to control the fan speed. Dan McDonald left me a comment pointing to his project on Github . He basically connected the fan to a USB relay that can be controlled by Python script. His project inspired me to make a similar mod that would make use of the spare D1 Mini boards I have lying around. The plan is to hook up the fan to a MOSFET (2N7000) and control it via PWM. Here's the very simple circuit: The code simply reads a single character from the serial port (0 - 9). 0 will turn the fan off, while 1 - 9 will generate a proportional PWM to drive the fan, with 1 being the lowest and 9 being the highest. Here's the Arduino code: #include <Arduino.h> void setup () { Serial . begin ( 9600 ...

Installing and customizing CoreELEC in X96 Air

I previously installed CoreELEC on another TV Box ( Ugoos X3 Pro ), which unfortunately died after only 9 months during the summer (due to the unit overheating, which I learned is a common problem for cheap Android TV boxes). So this time I purchased a X96 Air  (4GB/32Gb) and had to do the whole thing again. So this is a note-to-self in case I ever have to install CoreELEC again on some other device. Installation of CoreELEC is simple enough by following this guide . Basically, it involves downloading and writing the firmware to a microSD card using usbimager . Then insert the microSD card, reset the unit and hold the reset until the logo appears. The unit will then proceed to boot into CoreELEC. First thing is to connect to WiFi, then enable SSH. This allows me to login via ssh and execute: ceemmc -x from the terminal. This writes CoreELEC to the built-in eMMC storage, after which I am able to remove the microSD card and reboot the unit into CoreELEC via the built-in sto...

DC-DC Buck Stepdown Converter for ESP8266

I am working on a project that requires a step-down converter from 12V to 5V, that will then power a WeMOS D1 Mini. I saw this new mini buck converter based on the usual LM2596 MP2307 , so I thought I'd give it a try. Unfortunately, it didn't work. Although it is supposed to be able to supply up to 1.8A, the D1 Mini was not able to boot up. The 5V pin was being properly supplied, but the 3.3V pin measures at only ~1.3V. So I had to go back to my usual LM2596 module, which is much larger, but works to power the D1 Mini with a 12V source. Here's a great review of the mini buck converter I found while trying to figure out how to make it work. The fact that it has high quiescent current (~60mA) is also mentioned in a few other sources.
