[Android 4.2.2](http://www.engadget.com/2013/01/11/android-4-2-2-supposedly-shipping-with-new-nexus-4-units/) began arriving on an assortment of Nexus devices [yesterday](http://www.engadget.com/2013/02/12/android-4-2-2-update-reportedly-arriving-on-galaxy-nexus-phones/) with "performance and stability" improvements listed as the only changes, but _Android Police_ dug into Google's change logs and compiled a list of small tweaks. With the update on board, Play Store downloads now display the time left to their completion, and Android Debug Bridge security is shored-up with the addition of a whitelist. Now, WiFi and Bluetooth tiles can be toggled by a long press in the notification Quick Settings. The release also makes hardware play a tone when it begins to [charge wirelessly](http://www.engadget.com/2013/02/11/nexus-4-wireless-charger-now-on-sale-for-60-at-google-play-stor/) with less than 95% juice left, and uses new low battery and cord-free charging chimes for the Nexus 4. Reports about possible Bluetooth fixes are mixed according to _Android Police_, and a reference to patching them up hasn't been spotted just yet. If you'd like to take a look at Mountain View's code commits, give the neighboring source link a jab.
