Several leaked screenshots, as well as a leaked ROM, have given consumers an early look at Android 4.3 Jelly Bean, a rumored upcoming update to the operating system. Since this it has not been released officially, however, the changes that had been identified may not be final.
Always On Wi-Fi
One of the screenshots shows the Advanced Wi-Fi settings, which has a “Scanning always available” option. Google mentioned this in this year’s I/O as a way to give apps information regarding the user’s coarse location without having to turn on the GPS. According to Google, an Always On Wi-Fi feature saves more battery juice than using GPS. That said, the feature can be turned off in the settings.
Bluetooth Low Energy
This is a feature that allows users to enjoy Bluetooth connectivity without consuming too much power. This is useful for accessories like heart monitors and smartwatches.
Testing and Debugging
Some options for testing and debugging to help developers optimize apps are included in the update.
Android 4.3 allows users to incorporate pauses or waits to one’s dialing string, by means of commas and semicolons. This is accessed via the Phone app’s menu. The Settings also allow for dial-pad autocomplete as well changing tone lengths.
The changes in the camera are already present on the HTC One and Samsung Galaxy S4 Google Play Edition, but not on Nexus handsets. In Android 4.3, the settings bar has been changed into a semicircle. The volume button is now able to function as a shutter, as well. There are not many changes to speak of, however, in terms of functionalities.
Since this is a pre-release build, Google could introduce more features, or even remove some of the ones that appear on the list. Judging from the leak, however, it appears that the changes will not be very dramatic. It is, after all, just a minor update. More radical changes in terms of design and functionalities would likely be available when Google finally releases Android 5.0 Key Lime Pie.
