Updates
Your Energy Phone Pro 3 has an Android(TM) operating system that can be reinstalled or updated if necessary.
Updates will be carried out via OTA (Over-The-Air) by default, so your Energy Phone will automatically
connect to our servers, download the file and install the new software as soon as an update is released.
You can also update your Energy Phone Pro 3 using your PC. The process is simple but has to be done carefully
and only when is really necessary. If the device does not respond, restarts unexpectedly or you experience
problems accessing the content stored on the built-in memory, you should reinstall or update the operating
system to the latest compatible version available.
Please follow these steps to install it:
Make sure that the battery of your Energy Phone Pro 3 is fully charged. If this is not the case, plug it into an
external power source using the provided AC/DC power adapter and wait until it is fully charged.
