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

I realized after my Ugoos box died that overheating is a big problem with cheap Android TV boxes. A teardown of the Ugoos box shows that it does not have any heatsink or fan at all!  The X96 Air does have a heatsink, but the heatsink is located at the bottom of the casing with no ventilation. In this default configuration, with the ambient room temperature at 25c and playing a 1080p video, I was seeing the CPU temperature at 67c. I drilled a couple of holes at the bottom of the casing. The CPU temperature fell to 59c with the box raised about 2cm with plastic blocks. I retrieved an old 5V laptop fan: Then cut and strip away a spare USB cable: Solder the red and black wires on the fan and the cable: Secure the fan to the bottom of the casing with double-sided tape, then plug the fan into the box's USB connector. Here's a view of the box with some 3D-printed risers installed at the bottom to give the mounted fan sufficient clearance: The CPU now runs at 43c, a huge drop from the ...

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...
