Troubleshooting
Why is not possible to play some MP3 files?
7.
The MP3 file must follow the Layer 3 Standard for MPEG-1, MPEG-2 or MPEG 2.5 formats. Otherwise, it has to be
converted using specific software.
My Phone does not turn on, what can I do?
8.
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?
9.
Make sure you are not trying to play WMA files with DRM.
Why is not possible to display video files, images or text while using the music player?
10.
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
(songs with the music player, videos with the movie player, etc...) while you browse the folders of that specific
application. In order to see all the files stored on the internal memory at the same time, start the file explorer
application from the application menu.
Which video formats are compatible with my Phone?
11.
Your Phone can play several video formats like MP4, 3GP or MOV among others without needing to recode.
Why is not possible to display my jpg images?
12.
Many digital cameras and image editing software add hidden data to jpg files. This can prevent your Phone from
loading the images. Try deleting them and save the images with another name.
Sometimes the screen turns black and the device does not respond.
13.
It is always better to restart the device through one of the available system options but if this is not possible,
please restart it by pressing the power and volume buttons for about 10 seconds.
The built-in memory of the Phone Pro 4G Navy is 16 GB, but the available memory is lower. Why?
14.
The Android™ operating system and the preinstalled applications need approximately 6 GB internal memory to
work properly. Therefore, the available memory for additional data is less than 16 GB.
What do I have to do to install an application?
15.
First of all, make sure that the file has the Android™ application extension (.APK). Then, Android™ will ask you to
activate the app installation from "Unknown sources" option, which has been disabled for security reasons. To
enable the installation of apps, you only have to follow the instructions on the screen the first time you try to
install an application: Settings / Security / Unknown sources (activate). This action may compromise the device
security. Therefore, we strongly recommend to install applications from reliable sources only.
How long does the battery last?
16.
It depends largely on the usage conditions such as the screen brightness, the use of headphones or speaker,
whether the Wi-Fi connection is enabled or disabled and the use of GSM, 3G and 4G networks. The battery life of
the Phone Pro 4G Navy lasts up to 165 hours on standby and 15 hours in conversation mode.
Which are the 4G and 3G operating frequencies of my device? Your Phone Pro 4G Navy is prepared for the
17.
