Android 4.3 Jelly Bean Optimized Bluetooth but UI almost the same

Though there is not confirmation yet officially. But the Android 4.3 ROM new expusure recently can be really downloaded. We guess soon the new update would come for Android mobile phones and Android tablets.

After we installed the ROM into the device, we can see the UI is almost the same as the previous Android 4.1 or 4.2 system. Only very few parts are changed. One thing confirmed was that Android 4.3 started to support the Bluetooth 4.0 low power-consumption mode as we could see the "android.hardware.bluetooth_le" process. What's more, in the WiFi settings, there is a new option "always search for Wi-Fi siginal", which would provide locating function via WiFi.
For other updates, let's wait and see. But the Android 4.3 system would be just optimization edition of Android 4.1. The Android 5.0 would be probably the one that would make big changes.
