Troubleshooting
Why is not possible to play some MP3 files?
1.
The MP3 file must follow the Layer 3 Standard for MPEG-1, MPEG-2 or MPEG 2.5 formats. Otherwise, they have to
be converted using specific software.
My tablet does not start, what can I do?
2.
Make sure that the battery has enough charge when trying to turn it on. If the problem continues after charging
the device for at least 30 minutes, there may be a problem with the installed operating system. Please refer to
the Updates section of this manual.
Why is not possible to play some WMA files?
3.
Make sure you are not trying to play DRM-protected WMA files.
Why is not possible to play video files, display images or text while using the music player?
4.
In general, applications only display the files that are compatible and that the programme is able to read.
Therefore, you will only be able to display the files with the format that is compatible with that programme while
you browse the folders from that specific application. In order to see all files stored on the internal memory at
the same time, run the file explorer from the system settings menu or install an app supported by the device.
Why is not possible to display my jpg images?
5.
Many digital cameras and image editing software add hidden data to jpg files. This can prevent your tablet from
loading the images. Try using them by saving the image through another app.
The screen has turned black and the device does not respond.
6.
Keep the power button pressed for a few seconds to reboot your tablet.
The built-in memory of the tablet is lower than specified. Why?
7.
Its operating system and the preinstalled applications need a part of its internal memory to work properly.
Therefore, the internal storage capacity available is a bit less than specified.
I have upgraded the firmware and I no longer have any multimedia file nor wallpapers. How can I retrieve the
8.
contents that came preinstalled?
Before carrying out any system upgrade, we recommend making a backup of everything you want to keep. In
www.energysistem.com/en, you will find not only all the preinstalled content but many more multimedia files
and additional wallpapers.
What do I have to do to install an application that is not in Google Play Store?
9.
First of all, make sure that the file has the Android installation extension (.APK). When you open it, Android will
ask you to activate app installation through the "Unknown sources" option, which has been disabled for security
reasons. To enable the installation of apps, please follow the instructions on screen the first time you try to
install an application: Settings > Security > Unknown sources (activate).
The battery life of my tablet does not match the one indicated in this manual. Why? Battery life depends largely
10.
on how you use the device, that is, how high you set the level of screen brightness, the use of headphones or its
built-in speaker, the Wi-Fi settings or the power required for the apps and games that are running.
