Android 4.3 upgrade, whats new ?

Really eager to know, what android 4.3 bring off to the table? Google finally took the wraps off the new version of Android it neglected to announce back at I/O (instead releasing new features via Play Services instead). Here’s what’s new.

Control User Accounts with Restricted Profiles

In Android 4.2, Google added the ability to created additional users for a tablet, much the same way that Windows handles users. In Android 4.3, device owners can create restricted profiles that have limits on what a user can do. For example, you can prevent a child’s account on a device from being able to make in-app purchases. Developers can also make its app behave differently based on which type of profile it’s being viewed in. In the example app shown, the child’s account can’t even see extra levels available for purchase

Bluetooth Can Now Pair with Low-Power Devices

Google added new Bluetooth 4.0 features that allow devices to pair directly with low-power devices. This is great news for people who use fitness sensors and such. During the demo, Google put a heart rate monitor on an engineer doing jumping jacks, and his heart rate was updated live on a phone a few feet away in real time.

Keep Location Features with Always-On Wi-Fi Scanning

Wi-Fi often does double-duty as a location service if you don’t want to leave GPS on all the time. If you switch off Wi-Fi to save battery, though, this brings location services down with it. In Android 4.3, your device can continue scanning for Wi-Fi in a more passive mode that uses much less battery, but still pings for networks so you can keep location-based features. If you’d prefer not to do this, you can disable it in Settings.

If you’re feeling a bit underwhelmed, consider directing your attention to the Play Services announcements made back at Google I/O earlier this year. As we’ve noted before, Google’s beginning to shift new features to this platform, which can be updated independent of a new OS announcement. This may mean fewer sweet new features for Android updates themselves, but you also won’t have to wait as long to get your hands on them.

Enhanced Camera UI

This change goes unknown in the google official list, but the new camera on nexus devices is more single hand operation friendly with slight improvement in image quality as well.

Enhanced performance on older devices using TRIM

It’s no secret that many Android phones and tablets show a decrease in performance over time. Nexus devices are not immune — it’s particularly noticeable with the original Nexus 7. Our friend Brian Klug over at AnandTech discovered an interesting tidbit while testing the new and improved Nexus 7: Android 4.3 supports TRIM. What this means is that Google’s mobile OS can now instruct the flash storage controller when to collect / recycle unused data pages / blocks. The net result is that devices running Android 4.3 will no longer become sluggish with time — in fact, existing Nexus handsets and tablets will see performance improve after the update. It also looks like Jelly Bean invokes TRIM maintenance once within a 24-hour window (after one hour of inactivity), and only if the battery is 80% full (30% when charging).
