Today, reports are suggesting that Samsung released the update to Android 5.0 Lollipop for the Samsung Galaxy Note 4 in the United Kingdom. This update, which weighs in at a little over 700 MB, brings the newer version of Android to the Note 4 plus a number of bug fixes. These include the expected stability and performance improvements. The update is being made available to devices of all carriers plus the unlocked version.
Android 5.0 Lollipop on the Note 4 brings with it a number of improvements to the core Android system, including a new network scheduler. The network scheduler is a system-wide function that's designed to conserve battery power by helping the device stay asleep when idle. It works when co-operating applications requesting a window in order to connect up to the Internet in order to perform activities, such as synchronizing the data. Older versions of Android allow an application to connect to the Internet as and when it wants to, which means the device may be woken at any time The network scheduler can in theory greatly reduce the number of times a device the device is woken.
Another improvement is the adoption of a new application runtime, switching away from Dalvik to the Android RunTime. The Dalvik runtime is a "just in time" application compiler system, which means that when an application is launched, the operating system must first complete compiling the application and subsequently run it. This reduces the amount of space that applications occupy on the device but increases the processor load. Conversely, the Android RunTime has pre-compiled applications on the device, which require more space but are faster to launch. The performance difference is welcome, even on a device based around the powerful 2.7 GHz, 32-bit Qualcomm Snapdragon 805 processor with 3 GB of RAM, but applications and animations are noticeably smoother on Android 5.0 Lollipop compared with Android 4.4 KitKat and older.
