START-UP AND POWER LOSS
After download or device reset it is necessary
to wait for about 2 minutes without
performing any action
to make it possible a proper calibration of:
Proximity sensor.
Luminosity sensor.
Button presses.
For a correct calibration of the proximity and brightness sensors it is recommended not
to approach less than 50 cm from the device during this time and to avoid that the light
strikes directly.
