Feb 16, 2009 Samsung unveiled the Blue Earth phone with a solar battery and a touch screen.This is a true smartphone based on Android, but its case was made of recycled plastic bottles. To save energy, Samsung made a special software that adjusts the brightness of the screen and also disables Bluetooth, 3G, and Wi-Fi modules if the battery charge is critically low. Additionally, the Blue Earth was counting function emitted into the atmosphere as carbon dioxide on the basis of data on the number of steps taken. Alas, solar panels in smartphones has not caught on and this model, like other companies, was just a demonstration of what Samsung cares about the environment.
