Correct and accessible information on how set up Samsung Galaxy internet, necessary for every owner of this phone.

The problem of setting up the Internet on Samsung Galaxy and Note smartphones concerns devices of the “gray” type, since the overwhelming majority of certified profiles already have the Internet configured.

Samsung Galaxy smartphones and the Internet

All Samsung Galaxy smartphones have the ability to access the World Wide Web. There may be several options:

Via a 3G operator, for example, LTE-A, LTE, GPR, EDGE.
By connecting to Wi-Fi.

Setting up 3G Internet on Samsung Galaxy

It should be noted that most methods of connecting to the Internet through 3G operator networks have a paid basis. But there are optimal options, such as an unlimited tariff or special offers, which are most often represented by megabytes included in a specific service. In the latter case, it is necessary to check the correct operation of the Internet.

Thanks to the special data transfer settings provided by your chosen telecom operator, you can make sure that there are no problems with connecting to the Internet. This is done in several steps:

Find the “Settings” menu on your smartphone and open it;
open “Other networks”;
go to “Mobile networks”;
open "Access Points". At this stage, you can find out what Internet access profiles are available on your mobile device or make sure that they are missing.

If the Internet is available, you will only have to ensure that data transmission is turned on in the so-called “blind”. If there is no access profile, then you will need to set it up yourself or contact the network operator using a toll-free service phone number. It’s not particularly difficult to set up access yourself; you just need to fill in the “profile name” field, as well as all the fields in the “access point”.

Setting up the Internet via Wi-Fi

Wi-Fi is rightfully the most accessible and inexpensive way to access the Internet through Samsung Galaxy and Note smartphones. Despite the fact that there are paid networks, free Wi-Fi can be found everywhere and in large quantities. This makes this connection very convenient.

Everyone can get their own Fi-Wi, you just need to buy a router at specialized retail outlets. The cost of such a device does not exceed 600 rubles. Having purchased the device, all you have to do is contact your provider so that the technicians can set up the device for you at a time convenient for you.

Wi-Fi networks are available for your Samsung Galaxy and Note in many public places: shopping malls, cafes or train stations. Such Internet has undeniable advantages: it is completely free, has good speed and stability.

What if the Internet doesn't work? Your actions

If you have set up the Internet on your Samsung Galaxy smartphone, but for some reason it does not work, you should find the cause of the failure. First of all, check your account balance. If everything is fine with it, use the online service of your telecom operator and activate data services. Be sure to check with your operator which Internet access service package will be optimal for the current tariff plan. You need to make sure that GSM/WCDMA mode is enabled in your gadget’s network settings.

The 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 features. Both smartphones have received a lot of positive reviews from reviewers and real users.

If you've already bought one of these smartphones, we've got a whole collection of tips and tricks you can use on Samsung's top 2017 flagships. These tricks will make you look at the Galaxy S8 and Galaxy Note 8 in a completely different way. So let's get started.

Home button pressing force

The Galaxy S8 and Note 8 smartphones have stunning 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. You can also press the Home button hard to return to the Home screen from the active app. 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 chapter " 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. Only after this the lock screen and iris scanner will appear. Quite a long process, isn't it? Fingerprint scanner works easier!

Samsung foresaw this point and added a convenient function “ Unlock via iris when screen turns on" The function is in the menu " Settings» — « Lock screen and security" By enabling this feature, the iris scanner will start scanning as soon as you wake up your Galaxy S8 or Galaxy Note 8 smartphone.

Quickly hide the navigation bar

If you are reading news on a website or a book, then you should know about one convenient way to quickly hide the navigation bar on the Galaxy S8 and Note 8. To do this, just double-tap the small dot located on the left edge of the navigation bar. To bring back the navigation bar, simply swipe up on the screen and double-tap the dot.

Expand status bar

You can quickly expand the notification panel on your Galaxy S8 or Note 8 by simply double-tapping the status bar. This feature only works if you are using the default launcher and have not installed other user interfaces.

Quickly open the camera app

As you know, you used to be able to double-click the physical Home button to open the camera app. But the Galaxy S8 and Note 8 don't have a physical Home button. 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

Another useful trick on the Galaxy S8 and Note 8 is to quickly switch between the front and rear cameras. When you already have the camera app running, you can swipe up or down on the screen to switch to front/rear camera. An even quicker way to switch to the front camera is to double-press the power button while the camera app is running.

Decrease or increase flashlight brightness

If you use the flashlight on your Galaxy S8 or Note 8 a lot, you'll want to know that you can change its brightness. To do this, click on Flashlight in the Quick Settings panel and you will see a brightness slider. Five different brightness levels are available to the user.

Use secure folder

Latest Samsung smartphones have a secure folder called Secure Folder. You can hide banking or corporate applications in this folder. All applications located in the protected folder run in a separate sandbox, completely disconnected from the main operating system.

Blue light filter

Like any modern Android smartphone, the Samsung Galaxy S8 and Note 8 are equipped with a blue light filter. As the name suggests, a blue light filter automatically filters out harmful blue rays emitted by your display by adjusting the color temperature. If you often read on your Galaxy S8 or Note 8 smartphone, it is recommended to turn on the blue light filter, especially when reading in the dark.

Smart screenshot

Samsung offers not only to take a screenshot of the screen, but also to quickly cut out a picture, draw something, add filters, effects, and much more. Another cool feature is that after taking a screenshot, click the Crop button and the navigation bar and status bar will be removed.

Change system fonts

Samsung is one of the few smartphone manufacturers in the market that allows you to change the system fonts on their devices. Such a small feature can completely update the user interface and give new life to a smartphone.

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.
