For example, you can set the autofocus range in Pro mode of the camera app. We would like to explain how this works.

If you want to surf the mobile Internet with your Samsung Galaxy S8, then it is best to be logged into the LTE or HSPA network of the mobile operator. Here, the data transfer rate is best. In fact, you do not need to worry about it, because the Samsung Galaxy S8 performs its own network switching when a better network is available.

Unfortunately, this works on the Samsung Galaxy S8 only conditionally well. Because often the smartphone simply remains in the edge network. This is shown by the fact that only a small “E” can be seen at the top of the status bar next to the grid display. The Internet connection is accordingly very slow, which makes dissatisfaction.

Since it is very likely a problem with the firmware, the only help here is a new update from Samsung. However, we have the following little tip for you, which immediately helps to use a faster mobile internet connection.

1. To do this, drag down the status bar once
2. Activate the toggle "Aircraft Mode" - Wait about 5 seconds until all connections are interrupted
3. Disable the aircraft mode

So your Samsung Galaxy S8 looks for the best network and that is then usually better than the E network. Please consider, that in rural regions often no better network than the Edge net is available.

You now know what you can do if the Samsung Galaxy S8 is hanging in the edge net and does not perform intelligent network switching.

If you receive a new notification on your Samsung Galaxy S8, you will be informed about it on the screen in the form of symbols and parts of the content. If you do not want this, or for example only want to see icons, then you can adjust the settings as follows in Android:

1. Start from the S8's home screen, then open the app menu and continue the settings.
2. Scroll down and select "Device Security"
3. Navigate to "Notifications" - The following options are now available:

• Hide content
• Notification icons

Set the setting the way it suits best to you. You can also choose which applications are displayed on the Samsung Galaxy S8's screen. If you do not want to see any notifications on the lock screen, set the master slider to "Inactive". Finished!

You now know how to hide the notifications on the screen, display them only partially or completely disable them on the Samsung Galaxy S8.

If you are using the camera app of the Samsung Galaxy S8 to take photos, then you will have noticed that when you press the shutter button a bit longer, you will automatically take a series shot (burst mode).

If this happens more often, although you do not want to create a serial image, then you may ask: Can I disable the burst mode (serial photos) on the Samsung Galaxy S8? The answer is as follows:

Unfortunately, you cannot simply disable the serial image function in the official camera app of the Samsung Galaxy S8.

It remains to be seen whether and when this will be possible again in the future. Since, however, the S7 had no deactivatable serial image function, this is probably synonymous with the S8 no longer integrated into the firmware.

If there is a change in one of the next firmware updates for the S8, then you can read this here.

A photo grid is a collage of images. In this case, the layout is usually arranged in the form of a lattice, although larger image elements may also be included.

Anyone who has ever heard of the term "fake call" may wonder what it is about. Who is deceived and how does such a call actually work? This is what we would like to explain to you in this article.

A fake call is supposed to pretend a call that does not actually exist. This means that your smartphone rings, even though nobody calls you. Such a call is actually always controlled by an app. Depending on how professional the app is, you can set different scenarios here. For example, a call can be made at a fixed time, or even when you press a specific key on your smartphone. Even a voice recording can be played back when the call is accepted.

Why the whole thing?

You can easily get rid of an unpleasant situation with an apology.

For example, if you are squeezed by an aunt or uncle over your private life at a family celebration, a bluffing call can get you out of this situation quickly and easily. The smartphone rings and then as an excuse to your relative it can be said: "It is important, I am short outside". So you have liberated yourself politely and uncomplicatedly from an unpleasant situation.

Where can I find matching apps for my smartphone?
