Android 4.4.4 Difference from 4.4.3 KitKatAndroid 4.4.4 and Android 4.4.3 KitKat versions are identical to one another except for the patch related to security. Android 4.4.3 version has been reported with vulnerability on the OpenSSL that can cause man-in-the-middle attack.
Any device vulnerable to such can expect flawed security measures that hackers, spammers and similar attackers may use in order to retrieve vital information. Android 4.4.4 KitKat delivers the patch that fixes the crucial issue on the previous version. But since Samsung needs to make apps and services compatible with Android 4.4.4 KitKat, expect a little bit more than that.
Possible Samsung Package
Since Galaxy S3, Galaxy S4, Galaxy S5, Galaxy Note 2 and Galaxy Note 3 features TouchWiz UI and several Samsung Galaxy exclusive apps and services, users may get something more out of the official Android 4.4.4 KitKat update. Some of parts from Samsung's Android 4.4.4 KitKat firmware may include updates on the Samsung Knox Security, Bluetooth connectivity bug fixes, optimisations of Galaxy apps and services and other various enhancements. Additionally, the company may also decide to port some Galaxy S5 software exclusives such as Download Booster and Kids Mode which already happened on Galaxy Note 3.
Android 4.4.3 May Be SkippedLike Motorola and Sony Mobile, Samsung may even skip Android 4.4.3 version in favour of the positive benefits on Android 4.4.4 KitKat. Right now, Motorola is seeding live the Android 4.4.4 KitKat updates for Moto X, Moto G, Moto E, Droid Ultra, Droid Maxx and Droid Mini which features some improvements to various applications including camera and security stability. Sony Mobile on the other hand started to seed the official Android 4.4.4 KitKat for Xperia Z1, Xperia Z Ultra and Xperia Z1 Compact which will later be sent out to other Xperia Z series such as Xperia Z2 and Xperia Z2 Tablet. These Sony Xperia devices also received improvements on the camera functionality, in-call audio with fine-tuned noise cancellation, FM radio, graphics and bug fixes on top of the security implementation of Android 4.4.4 KitKat from Google. Samsung has a history on skipping Android version before on Galaxy S3 and Galaxy Note 2 by favouring Android 4.3 Jelly Bean than Android 4.2. It is a possible choice for the company to jump straight on Android 4.4.4 KitKat for better consumer experience.
