Android 4.3During the June 24 event, Google finally unveiled Android 4.3, and also presented the first device that will ship with the new operating system: the new Nexus 7. The long awaited operating system, that leaked numerous times and hinted at what changes it will brings, is not that big of an update to deserve the denomination of 5.0, so it is still called Jelly Bean. The update is not at all an impressive one, however it is one that brings numerous improvements. Here is a presentation of the more important changes in Android 4.3:

Bluetooth Smart

Bluetooth smartThis is a new feature that was rumored for 4.3 and finally arrived. It allows for a better Bluetooth management and a much lower energy consumption. It works very well with pairing multiple Bluetooth devices to the Android 4.3 devices.

Restricted Profiles

Restricted profileThis feature expands the already introduced Multi User feature for tablets. It allows for user permission management, meaning that the tablet owner can select what the other users of the tablet can access and can not access without permission. This can prove very useful in families, especially the ones with children that cannot have access to unsafe content. Not even in-app purchases can work in the restricted profile, so this way children cannot make random purchases that empty the parents' pockets.

OpenGL ES 3.0

With this new technology, the graphic performance will increase considerably. This can allow developers to create games with a much better visual performance and graphics.

Increased performance, speed and responsiveness

Jelly Bean already came out with good performance optimizations, and these were even more improved in 4.3. Android 4.3 is now even faster and smoother thanks to the hardware-accelerated 2d rendering, triple buffering, CPU input boost and other improvements that were made. Multiple core processors are now used at an even greater performance, taking more advantage of their benefits. Everything is faster with Android 4.3.Of course these are not all the improvements, as Google has listed tons of other additions brought to the operating system. Take a look for yourself if you want. You'll find that the improvements are not really seen at the exterior, but they are there, and you will feel the improved performance when you try it.For now, Google is announcing that OTA updates are coming to all Nexus devices, while Google edition Galaxy S4 and HTC One still have to wait a while. Probably in a short while, other devices will get the new update, of course flagship devices first, as usual.
