Those of you with Nexus devices will most likely have received an update to Android version 4.2.2 by now. The news of the OTA was broken on the forums yesterday by XDA Senior Member kataria.vikesh. Those of you who have not are no doubt on the verge of applying the update manually after a lengthy session of gawping at your status bar awaiting that notification. Nexus 4 owners may find themselves waiting a little longer than the rest, as there doesn’t seem to be any sign of an update for the device yet. However, the changes have already been merged into some custom ROMs. This latest version, build number JDQ39, was also pushed to AOSP yesterday meaning that we should soon see this latest update becoming unofficially available on a whole host of devices.
So what exactly are the changes in 4.2.2? Well, we already know from the version number that this isn’t a huge update, there are however some notable additions to functionality and tweaks to the UI. Most of these are directed more towards the end user, but one of which will no doubt be a welcome addition for some developers out there so let’s start with that one.
ADB Whitelist: Connecting your device to a PC with USB debugging enabled will now bring up a prompt which displays your PC’s RSA key and offers the option to add this information to a whitelist. Unless a specific computer is allowed access via this prompt, the device will be inaccessible via ADB. This of course adds an extra level of security to the device. Providing you use a secure lock screen any potential thief with a little ADB knowledge will be unable to access the prompt and add themselves to the whitelist. Unfortunately, it seems that this feature may not provide much more security for users with an unlocked bootloader, according to the guys at Android Police.
Other changes include:
- The addition of an estimated remaining time and progress percentage to the ongoing download notification
- New sounds for wireless charging and low battery alerts
- Long pressing WiFi and Bluetooth on the 4.2 quick settings now allows them to be used as conventional toggles, albeit in a rather unconventional way. Silly Google.
There’s speculation as to whether the issue of streaming music over A2DP has been addressed. Some users are reporting an improvement, whereas others are not. If anyone is able to spot this in the commits then please let us know in the comments.
