Samsung Galaxy S8 and Galaxy Note 8 have a lot in common not only in terms of their internal components, but also in terms of software functionality. Both smartphones have received a lot of positive reviews from reviewers and real users.

Home button pressing force
The Galaxy S8 and Note 8 smartphones have amazing Super AMOLED displays that occupy almost the entire front panel. Due to this, there is no room left for capacitive navigation buttons under the screen. Don't worry, there are buttons, but now they are located on the screen itself.
But that's not all: the area where the Home button appears on the Galaxy S8 and Galaxy Note 8 supports Force Touch, or pressure. This means you can press hard on this area to wake up the display. So you can press hard on the Home button to return to home screen from the active application. Considering the fact that the fingerprint scanner on the Galaxy S8 and Note 8 is in an awkward location, pressing the Home button to wake up the smartphone is a great alternative.
If the pressing force on the Home button does not work for you, then you need to enable the option " Unlock using the Home button" in the section " Settings"->"Screen".
Automatic activation of the iris scanner
By default, if you use the iris scanner on the Galaxy S8 or Galaxy Note 8 to unlock the device, you first need to press the Power button or Home button to wake up the device.

Instead, you need to press the Power key twice to open the camera app. The feature is disabled by default, so you should enable it in the Settings menu
Quickly switch between the main and front cameras
One more useful trick Galaxy S8 and Note 8 is fast switching cameras on the front and rear panels. When you already have the camera app running, you can swipe up or down on the screen to switch to front/rear camera. Even more quick way switch to front camera– press the power button twice when running application cameras.

How is multitasking organized in Android?
Android applications consist of several components. There are four types of components: Activities, Services, Broadcast receivers And Content providers.
Activities represent a graphical user interface for a specific task. For example, an SMS application may have one activity for displaying a list of contacts, one for creating a message, etc. An Activity can be in one of three states:
1. Active or running – in this state it is in the foreground and interacts with the user;
2. Paused – is in the background, but visible to the user, for example, partially blocked by a new activity;
3. Stopped – completely blocked by another activity. But it still retains its state, although it is completely hidden from the user.
In the Paused and Stopped states, the activity can be unloaded from memory. A situation may arise when the user, returning to the unloaded activity, would like to see it in the state in which he left it. This is possible if you call the onSaveInstanceState() method before unloading the activity, and call the onRestoreInstanceState() method when restoring or creating the activity. In this case, it is possible to save the current (at the time of unloading) activity state. Here we can draw an analogy with the hibernation mode in PC OS.
