Removing WiFi or Bluetooth from Airplain Mode Android

Execute the following command in the command prompt or terminal:

adb shell

Then run the following command to prevent Airplane Mode from turning off WiFi:

settings put global airplane_mode_radios cell,bluetooth,nfc,wimax

Alternatively, you could do this command to prevent Airplane Mode from turning off WiFi and Bluetooth:

settings put global airplane_mode_radios cell,nfc,wimax

Each item we remove from the list tells Android to leave that radio on when Airplane Mode is toggled on. If you ever want to return things back to how they were, you can execute the following command in an ADB shell prompt:

settings delete global airplane_mode_radios


Normally, Airplane Mode will shut off cellular, WiFi, NFC, Bluetooth and WiMAX (if it exists) radios, but removing one or more of these from the list with the ADB command shown in makes it so that it’s ignored. In the example, both WiFi and Bluetooth stay on when I enable Airplane Mode.

This is why the command only includes cellular, NFC, and WiMAX options. Since we’re leaving those two radios out of the ADB command (WiFi and Bluetooth in this case), Android will leave those radios alone when you toggle Airplane Mode on. You can use any combination here by leaving out any of these options, and even make it so that cellular radios stay on when you turn Airplane Mode on.

So you may want to know that there’s also a way to stop a device from turning on one of these radios when Airplane Mode has been enabled. The preference is controlled by changing the values in the global preference “airplane_mode_toggleable_radios”. For example, you can make it so that you are unable to turn WiFi back on if you choose by entering this command:

settings put global airplane_mode_toggleable_radios bluetooth,nfc

By default, the options given to this command are WiFi, Bluetooth, and NFC. But if you leave one of them out when executing the command above then you stop the device from turning that radio back on. This can be a good idea for a child’s smartphone or tablet, or even used as a fail safe to make sure the radio isn’t turned back on when Airplane Mode is on. This feature will likely be less useful than the one detailed in the big guide above, but it’s something that you may want to be aware of.

Welcome to the Android O Developer Preview!

Welcome to the Android O Developer Preview! You can download system images for a range of hardware devices that you can use for testing your app, from phones to tablets and TV.

To flash a system image:

  1. Download the appropriate system image for your device below, then unzip it to a safe directory.
  2. Connect your device to your computer over USB.
  3. Start the device in fastboot mode with one of the following methods:
    • Using the adb tool: With the device powered on, execute:adb reboot bootloader
    • Using a key combo: Turn the device off, then turn it on and immediately hold down the relevant key combination for your device. For example, to put a Nexus 5 (“hammerhead”) into fastboot mode, press and hold Volume Up + Volume Down + Power as the device begins booting up.
  4. If necessary, unlock the device’s bootloader using one of the following methods:
  5. If you are updating a Nexus 5X or Nexus 6P device using the hammerhead or angler builds, update your fastboot tool to the latest available version (>=23.0.1), and then run this command:fastboot flashing unlock
  6. If you are updating an older device, run this command:fastboot oem unlock

    The target device will show you a confirmation screen. (This erases all data on the target device.)

  7. Open a terminal and navigate to the unzipped system image directory.
  8. Execute the flash-all script. This script installs the necessary bootloader, baseband firmware(s), and operating system.

If you need the manual version, then the Nexus 6p steps is as follows:

./fastboot flash bootloader <bootloader file name here>.img
./fastboot flash radio <radio file name here>.img
./fastboot reboot-bootloader
./fastboot flash recovery recovery.img
./fastboot flash boot boot.img
./fastboot flash system system.img
./fastboot flash vendor vendor.img
./fastboot reboot

Once the script finishes, your device reboots. You should now lock the bootloader for security:

  1. Start the device in fastboot mode again, as described above.
  2. Execute:
    fastboot flashing lock
    or, for older devices, run:
    fastboot oem lock

Locking bootloader will wipe the data on some devices. After locking the bootloader, if you want to flash the device again, you must run fastboot oem unlock again, which will wipe the data.

Examine the state of Google’s upcoming Andromeda OS

I (Daniel Matte) decided to dig through open source to examine the state of Google’s upcoming Andromeda OS. For anyone unfamiliar, Andromeda seems to be the replacement for both Android and Chrome OS (cue endless debates over the semantics of that, and what it all entails). Fuchsia is the actual name of the operating system, while Magenta is the name of the kernel, or more correctly, the microkernel. Many of the architectural design decisions appear to have unsurprisingly been focused on creating a highly scalable platform.

It goes without saying that Google isn’t trying to hide Fuchsia. People have clearly discovered that Google is replacing Android’s Linux kernel. Still, I thought it would be interesting for people to get a better sense of what the OS actually is. This article is only intended to be an overview of the basics, as far as I can comment reasonably competently. (I certainly never took an operating systems class!)

To my naive eyes, rather than saying Chrome OS is being merged into Android, it looks more like Android and Chrome OS are both being merged into Fuchsia.

It is still not the time for purchasing a Google/LG watch just yet.

I have been contemplating on purchasing a Android Wear device and I was hoping for this release of the LG Watch Sport and Wear 2.0 to be the thing that put me over the edge, but no, it is still slow and using out of date hardware and the thickness, wearing a sports watch just to get the features that I want in a device? No thanks.

Perhaps hardware edition 3 can be the solution, until then I believe I will pass.

Arstechnica review LG Watch Sport review: Google’s bulky watch breaks free from the smartphone

Overall the LG Watch Sport and Wear 2.0 feel like a promising reboot of the smartwatch. If you’ve complained in the past that a smartwatch isn’t very useful, the package here offers a significant amount of stand-alone functionality. If you have any situations where leaving your smartphone at home or in a bag sounds like an attractive proposition, you might have a real use case for Wear 2.0

The Good

  • The machine learning powered QWERTY keyboard is fantastic. It quickly, easily, and silently inputs text into a smartwatch, adding a ton of great use cases.
  • The crown is great for scrolling while concentrating on the screen.
  • Android Pay might be slow, but buying things with a watch is great.
  • Google Fit’s exercise tracking might be the best feature of any fitness device.
  • The Play Store is an exciting model for a feature-rich smartwatch app.
  • LTE means you can leave your smartphone at home if you want.

The Bad

  • This is not a fast device. Loading anything is a laborious task. Random slowdowns happen occasionally.
  • It’s within the size range of some sport watches, but that is still really big.
  • I can’t stand these wireless “desk clock” chargers that only work under perfect conditions. Make a more secure travel charger.
  • Google has a lot of app work to do. Gmail, Google Maps, Hangouts, and other services need Play Store-style redesigns.
  • The Google Assistant on the Watch Sport is a hot mess. The hardware just isn’t fast enough to run this software.
  • Permanently affixed bands mean you’re stuck with one look.
  • It has a very incomplete emoji list.

The Ugly

  • Size, speed, and battery life are still issues, and Qualcomm is building smartwatch chips on 2013’s fabrication technology with old, underpowered CPU cores.
