Currently Android smartphones run Android 4.2.2 maximum – the update to Android 4.3 is currently only available to developers. Thanks to the Entwickerl version of Android, we could make but a glimpse of the new version of the operating system. But as of now, we can say: it is not worth this developer version on ’ s mobile Flash, because this is partly still buggy and also Android 4.3 offers little new features compared to the previous version.
For Android 4.3 jelly bean most changes take place only under the surface. The changes concern so no visible controls of the operating system, but a focus on the performance itself and workhorse. A Wi-Fi can now be disabled in the menu and still in a power saving option “ active ” are left. This ensures that the Smartphone not constantly trying to Wi-Fi networks, but they nevertheless at least finds and displays. Similar to created the new Bluetooth is profile (low energy), which is also designed to save electricity. In addition the performance of the system has been improved, but only marginally – on the Samsung Galaxy S4 performance by about 4% (Antutu benchmark) rises. More changes are useful only for developers, not for end users. All in all a rather maues update compared to Android 4.2.2.
Thus connected to nor a warning: it is sometimes recommended to download the new camera app of Android 4.3 on the Smartphone and install. In principle this offers nothing new, just a new look and operation, but no additional features. This app is not officially available in the Appstore, and must be installed through unsafe sources. We have recently reported by a known security hole in Android that can exploit this by means of a false signature. In the complete control of the Smartphone is then possible. To install a such app from an unknown source, so the risk always is, that this vulnerability is exploited undetected! Due to the very limited benefits in case of doubt, I would refrain from an installation. Here you will find the app in the video:
