Can I install apps that I have downloaded onto my Surftab on external storage devices, such as SD cards, USB stick, etc.?  

No, this is not possible. You can install apps only on the Surftab.

How do I access external storage devices (USB stick, SD card)?  

When you connect an external storage device, the Surftab displays a message to the effect that a device has been connected. Once this message is no longer visible, you can use a file explorer app (such as ‘ES File Explorer’ or ‘FileBrowser’ etc., available from the Google Play Store) to access and manage your data (copy, delete, edit).

Can I upgrade my Surftab to a newer version of Android™?  

If a firmware upgrade is available for your device, you can download it on our homepage under ‘Downloads’. A firmware upgrade may also be downloaded directly to your device via OTA, depending on your device.

Tip: Do not install any firmware on your device unless it is provided by us. Installing external firmware or custom ROMs may result in a loss of all warranty claims!

How do I add more storage space to my device?  

Your device has a memory card slot. Insert a card in order to add internal storage to it. Please consult the technical details of your device to learn which cards are compatible with it (in the technical data on the website (most up to date) or in the detailed operating instructions). These cards can be purchased in any electronics store.

Please note that it is not possible to guarantee 100 per cent compatibility of microSD cards (see “Why doesn’t my device recognise my microSD memory card?”).

How do I connect my Surftab to a Wi-Fi network? (Android™ 5.1 / 5.1.1)  

a) Select "Settings" from the applications menu or the quick menu. This is where you will find the "Wi-Fi" item. Tap "Wi-Fi".
b) Slide the on/off switch from left to right.
c) All available wireless networks will be displayed in the following window.
d) Tap the network that you would like to connect to. An input window appears. Enter the network key ("Password") for the wireless network you have selected and tap "Connect".
e) Your Surftab will connect to the Internet via the wireless network you have selected. You can now surf the Internet using a browser app.

-> Once you have established a connection to a WiFi network, your Surftab will automatically connect to it as soon as it is within reach. It is not necessary to re-enter the network key.

-> To save power, it is advisable to turn off the WiFi function when it is not in use.

How do I download apps using Google Play?  

You must sign in using a Gmail account to use the Google Play Store. You can sign in to your account when you open the Play Store app for the first time. If you do not yet have a Gmail account, you can set one up now.

How do I reset my device to factory settings?  

a) Open the applications menu and tap ‘Settings’.

b) Scroll down in the menu and tap the ‘Backup & reset’ option.

c) Then tap ‘Factory data reset’ and confirm this option.

Note that selecting this option will delete all data that has been subsequently installed (apps, login information, e-mail accounts etc.). This does not affect data stored on an external storage device.

How do I select my language if German is set as default language?  

After switching on the device, the start screen appears. To set the user interface to the desired language, please tap inside the applications menu on "Settings" and afterwards on "Language & input". Tap now in the right column on the first field "Language" and select your language.


For further information visit the product's download area on our homepage.

I do not find the menu item Language & input under Settings. In what direction should I swipe my finger across the screen to get to the menu items further down on the page?  

The displacement of the touch screen works in exactly the opposite direction as you would scroll down the computer screen using a mouse:  if you want to push the display on your Surftab down (for example to reach menu items positioned further down on the list, put your fingertips on the screen and swipe upwards. The display follows your movement and elements positioned further down on the display slide upward.

I have inserted a SIM card in my Surftab, but the Surftab does not recognize it. What can I do?  

When inserting the SIM card into your Surftab please always make sure that the Surftab is completely switched off and is not merely in standby mode. If you have inserted a SIM card into the turned-on Surftab, then after inserting simply turn the Surftab completely off and on again.

My Surftab has both front and back cameras. How do I switch between the two cameras?  

In the camera settings (see instructions), look for a camera symbol surrounded by an arrow. Tap this symbol to switch back and forth between the two cameras.

My Surftab is not responding. What do I do?  

If you can no longer use the device or if the device no longer responds to input, reset the device. Press and hold down the on/off button until the device switches off. Wait for about 20 seconds and then turn the device on normally.

My Surftab switches on when I connect it to a power source. Is this normal?  


Yes, this is perfectly normal. It allows you to see the charge level of the device. If you perform no further actions, the Surftab will switch to standby mode as it continues to charge.


My Surftab won’t charge. What do I do?  

Check whether your Surftab is properly connected to the charger. If your device still does not charge, connect it to your computer using the USB cable provided. This will allow you to determine whether the charger or battery is defective.

The Android Debug Bridge (ADB) is not recognising my Surftab. How should I proceed to enable access?  

Firstly, make sure that the USB debugging mode is activated in the Surftab developer options. If the developer options are not displayed, go to "Settings" -> "About Tablet" and tap "Build number" until "Developer options" appears under "System" (under Android™ 5.1.1 as a new option in "Settings"). Ensure that you have already installed and configured the latest Android SDK.


For Windows:
Go to the Windows device manager and check whether there is a device marked with a yellow exclamation mark (!) that corresponds to your tablet. Right click this entry and select "Properties". In the "Driver" tab, click "Update driver's software". In the window that follows, select the option "Browse my computer for driver software" and enter the path where the unzipped TREKSTOR "android_winusb" driver is located. If you receive a message during installation that prompts you to not install this driver, confirm with "Install this driver software".


Windows and MAC OS X:
It is now necessary to configure the ADB for the TREKSTOR tablet. You must add the TrekStor Vendor-ID (0x1e68) to the "adb_usb.ini" file in the hidden ".android" folder. To do so, proceed as follows:


1. Open the command prompt and enter the command "echo 0x1e68 >> $HOME/.android/adb_usb.ini".
2. Now check whether the device has been recognised by opening "cmd.exe" and entering the commands "adb kill-server" and "adb devices" in succession.


1. Open the terminal window and enter the command "echo 0x1e68 >> $HOME/.android/adb_usb.ini".
2. Now check whether the device has been recognised by opening „Terminal“ and entering the commands "adb kill-server" and "adb devices" in succession.

The display of my Surftab flickers! What is the reason for this and what can I do about it?  

This is a setting in the Development Settings of the Android operating system serving for programmers to visualize which part of the screen is being updated.
This setting can be easily deactivated via the menu item "Dev Tools" -> "Development Settings" -> "Show screen updates" by un-checking the box.

The front camera shows the image back-to-front. Is this normal?  

Yes. Before the shutter button is pressed, the front camera shows a mirror image. But the photo is saved in the way it looks in reality.

Which eBook formats are compatible with my device?  


The device supports all commercial eBook formats. However, you must install an appropriate app in order to read eBooks on your device. You can download these apps from a number of different providers. Consult the program specifications to determine which formats are compatible with the app you have selected.

Why does my device show less storage space than indicated on the packaging?  

The storage capacity stated on the packaging and in the technical specifications refers to the total storage capacity of your device. However, a portion of the total storage is also used by the operating system and system applications.

Why is no sound coming from my device?  

You may have headphones connected to the device. If headphones are connected the loudspeaker of the device is automatically turned off. Disconnect the headphones from the device to re-enable the speakers. If there is still no sound, check if the sound of the device is turned on and if the volume is set high enough.

Why does my device just switch off sometimes?  

If the energy level of the battery falls below a critical level, the device displays a corresponding warning. If you ignore these warnings, the device is put into sleep mode at a charge level of 6 per cent in order to counteract total discharge of the battery. Total discharge can lead to a situation where it is no longer possible to charge the device. For this reason, connect the device to the charger at this point at the latest in order to prevent data loss and damage to the battery.

Tip: Reducing screen brightness, closing all programmes or switching off the device entirely can speed up the process of charging the device.

Please note that the battery discharges itself over time, even when you are not using your device. In order prevent complete discharge of the battery (total discharge) and the associated damage, please charge your device intermittently. Following a total discharge, it is necessary to charge the device for a long period until it is can function properly again. Total discharge can also lead to a situation where it is no longer possible to charge the device. For this reason, it must be avoided at all costs.

If you have not used the device for a long period of time, charge it for a long period before switching it on again.

My device does not turn on, what can I do?  

Perhaps the charge of the battery isn't enough to turn the device on. Connect the charger to the device to recharge the batttery.

What can I do if the internal memory of my device is full or almost full?  

To relieve the internal memory of your device and free up memory space, you can save media files stored on the device (eg pictures, videos or text files) to an external data carrier (eg a USB memory drive or a suitable Memory card) or delete apps that are no longer needed.

Why is my WiFi not on the list of available wireless networks displayed on my device?  

First of all, make sure that you have enabled the WiFi feature on the device and that it is within range of the network.

If the desired network is still not displayed despite These measures, it may be that the visibility of the network has been restricted in the settings of the router (so-called "sppressed SSID").

Check in the settings of the router if this is the case.

To connect to a network with a suppressed SSID, go to the WiFi menu's settings and tap the three vertical dots in the upper right corner of the WiFi menu.

In the drop-down box that appears, tap "Add Network", enter the SSID of the network and tap "Save".
