Energy 2- User Guide

Remember that updates tend to have an expected size counted in hundreds of

megabytes, so we recommend that you carry them out when connected via Wi-Fi.

Updating via the GSM network may contribute to the operator charging for data

downloaded from the internet.

Please remember that before upgrading, the battery charge level should be

higher than 30%. If it is lower, plug the device to the power grid and charge the

battery at least to 30%.

While updating the device might restart on its own a few times. You should not

remove the battery or use any of device features, as this may cause the device to

stop working.

22. Safety remarks

22.1 Troubleshooting

In case of any problems with the device we strongly advice to make a copy of an

important data (contacts, SMS, photos, videos, music etc.) and restart the phone or

restore default factory settings.

If the problem continues, read the following tips and follow the given suggestions

in case of problems with a particular section:

• SD Memory card - check if it is properly mounted in the corresponding SD card

slot. If it does not help use another memory card of appropriate class and

capacity.

• USB - check the cable, by plugging another device. Check the form of a USB

connection in smartphone settings (shortcut available in screen notifications). If

it doesn't help, use another cable.

• Bluetooth - check whether the connection is active and Bluetooth visibility

options are enabled. Make sure that both devices are in Bluetooth connection

range and there are no obstacles between them (interesting fact - some LCDs

absorb magnetic waves). Make sure that the devices have a sufficient amount

of memory to exchange files. Make sure both devices have disabled the

aeroplane mode. It blocks Bluetooth, Wi-Fi, and cellular networks.

• Internet / Wi-Fi - Check if the aeroplane mode is not on. It disables using any

wireless network functions. Check network range. Check if the function is

activated in the device and the parameters set correctly. Check if the password

to the Wi-Fi network is correct.

• Sounds - make sure that the sound in the phone is not muted. Check other

smartphone sound settings. Check if the plug at the end of the cable is

connected correctly to the 3.5 mm minijack socket. Some minijack plugs differ

from each other which also might be a reason. Try another cable or use an

adapter.

• Photos and screenshots - check if the camera lens is not somehow obscured.

Check if the device has a sufficient amount of memory on the SD card or internal
