The Samsung Galaxy Note 8 runs on the operating system Android, in which various applications run during the operation. In addition to system applications, the CPU under RAM is also used by apps that have been installed by the user. Within this system errors and problems can occur, the cause of which cannot always be precisely located.

Such problems often manifest themselves in the form of overheating, slowness, frequent recharging of the battery, crashes, black screen, etc. In order to deal with these problems quickly, a method has proven itself in the past: the wipe cache partition.

 How to do this on the Samsung Galaxy Note 8 is explained in the following article:

The wipe cache partition is relatively easy to perform and does not result in loss of data. It usually speeds up the system enormously and solves problems.

And this is how the Wipe Cache partition runs on the Samsung Galaxy Note 8:

1. Turn off the note 8 completely
2. Press and hold the following keys to turn it on again:

• Volume Louder
• Bixby button
• Power On / Off

1. There should now be an Android male with an exclamation mark. That means you can let go the buttons. It takes about 10-40 seconds until the recovery menu of the Samsung Galaxy Note 8 appears.
2. Now use the volume key of the Note 8 to select in the menu the entry "Wipe Cache Partition".
3. You open the command by tapping the "Power Button" once. Confirm the query with "Yes" and the Wipe Cache partition will be executed on your Galaxy Note 8.
4. You are back in the menu before. It is marked "Reboot System Now". Here you only have to confirm once more with the power button to restart the Samsung Galaxy Note 8.

You have just run a wipe cache partition, which usually greatly improves the performance of your Samsung Galaxy Note 8.

If this has not helped, then often only helps a factory reset, in which the Android system is reinitialized. How this works is explained here.

The Mozilla Firefox browser has a feature that is enabled by default and may bother you. We are talking about the back function via the backspace key on the keyboard. Unfortunately, it can happen quite often that you write text in an editor, for example, and press the backspace key to go back one page. The written text is then lost, of course.

For this reason, we now show you how to disable the backspace feature in the Mozilla Firefox browser. Please proceed as follows:

Please enter the following in the address bar of the Firefox browser:

• about: config

Now confirm the security message and then look in the list for the following value:

• browser.backspace_action

For this value, there are now various settings that affect the backspace button:

• Value 0: When pressing the backspace key, a page is jumped back. (Default value)
• Value 1: Pressing the backspace key jumps to the top of the website.
• Value 2: or another value: This deactivates the function of the backspace button in Firefox

Now enter the number 2 and confirm with "Ok".

Then the Backspace button inside the Firefox browser is disabled.

There are currently three different sim card types in circulation: Standard, Micro and Nano Sim card. All types differ in size and shape. Thus, it is of course understandable that depending on the smartphone the right sim card must be used.

But you have to know which SIM card type your smartphone uses. Here's what we want to clarify here for the LG V30:

The following sim card size is needed for the LG V30:

• Nano Sim card

If you already own such a SIM card, you can immediately make phone calls with the LG V30. If you have an older format, you now have the following options to get a Nano Sim card:

1. You have a sim card with Nano-perforation

This is the simplest version. Simply press the Nano Sim card out of the existing Sim card along the perforation.

2. You have a sim card without a Nano-perforation

For this there are so-called "Sim card punching" available. A Sim card punch cuts out the Nano Sim card format from your previous Sim card. Such sim card punching is already available for little money on Amazon:

• "Good sim card punching"

3. Ordering Nano Sim card at mobile operators

If the effort is too big, so you can also simply request a new sim card from your mobile operator. This costs between 15 € and 25 € depending on which mobile service provider you use.

 You now know which Sim card the new LG V30 needs and how to get such a sim card for your device.

Android Oreo will be the new operating system with the version number 8.0. This will be available for many models as a firmware update. But it can take a while. Because many manufacturers are lagging behind with the software update.

So far, let's introduce you to the changes compared to Android 7. More about this in the following changelog to Android Oreo:

Changelog - Changes with Android Oreo on your smartphone or tablet:

1. Faster startup speed and stability

Android Oreo should boot twice as fast as Android 7. And the system should run more stable and fewer crashes to produce.

2. Longer battery life

Apps should be even more prevented from running in the background.

3. More security - Play Protect

 A hint should be shown in the Play Store, which should inform the user when an app poses a potential danger, for example from a virus. This new feature, called Play-Protect, is like a virus scanner. This checks also installed apps.

4. Mark texts more simply - Smart Text Selection

A selection help should make it much easier for the user of Android O to mark and copy sections of text. So phone numbers or addresses are marked by a simple tap. The software should be smart enough to extend this to other text modules.

5. Picture-in-picture mode

This makes it possible to use an app while watching a video. However, such a feature already exists, for example, on Samsung Galaxy devices with the pop-up player. To what extent a benefit prevails here remains to be seen.

6. Themes for notifications

You can sort notifications by topics and thus control them better. For example, you can disable all notifications related to "games" or "news".

7. Auto-complete passwords are now automatically used across systems by Google.

This means you only need to link to Google Account on new devices and your passwords will be automatically used.

These were the main changes in Android Oreo. In our opinion, nothing earth shattering but certainly an improvement in the operating system and stability itself.

The Samsung Galaxy S8 has implemented a feature called "edge lighting". This feature allows you to flash the page screen instead of pop-ups on notifications.

This feature had so far only a few settings. This has now been changed by a recent update for the Edge Screen. The "edge light" menu now has "advanced functions". You can find more information here:

Updating the side light or the edge screen

To do so, open the following submenu from the start screen:

• App menu --> Settings --> Display --> Page screen

You will now see the following screen:

Tap on "Update" and it will open the Galaxy App Store. Touch again on "Update". The download and the installation start. Then open again:

App Menu --> Settings --> Display --> Page Screen

Now tap on "Advanced Settings". Here you can now adjust your edge light as you like it. From "app color" to "custom color" to width and transparency, you can set everything. Use the individual submenus or the controllers for this. Afterwards, the edge light function on the Samsung Galaxy S8 is hopefully a little more attractive and visible than it was before.

The Samsung Galaxy Note 8 has a sensitive Touch display and can be woken up from the standby, for example, by pressing the Home key harder. If you have the feeling that your home button, or the touch sensor in the display behind does no longer works properly, then you can use the Samsung service menu to test this.

We'll explain how it works for the Samsung Galaxy Note 8. To do this, first open the phone app on the Samsung Galaxy Note 8 from the home screen and then the keypad. Now enter the following code via the numeric keypad:

• *# 0 * #

This will now show you the Samsung Service menu on the display. Here you can select the following from the menu squares:

• Sub Key

The Home button will now be displayed at the bottom of the screen. Press the button for a long time. If the display turns blue, the button works and you can leave the test via "Exit". If the display does not turn blue, something is wrong with your pressure sensor, which is behind the Home Button and you should take the guarantee.

You now know how to test on the Samsung Galaxy Note 8, whether the home button or the pressure sensor behind it works correctly..
