Updates
Your Energy Phone Max 3+ has an Android™ 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, will download the file and will install the new software as soon as an update is released.
You can also update your Energy Phone Max 3+ using your computer. 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 internal 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 Max 3+ is fully charged. If this is not the case, plug it into
the external power source using the provided AC/DC power adapter and wait until it is fully charged.

3.

areas like the belly of pregnant women, especially when making a phone call. If you have an electronic implant
(pacemakers, insulin pumps, neurostimulators...) place the phone at least 15 cm away from the body and on the
opposite side to the implant when making a phone call.
Do not expose your Energy Phone Max 3+ to temperatures or humidity outside the recommended range.
Operating temperature: -20 to 45 degrees.
