The Samsung E1107 (also known as "Crest Solar" or "Solar Guru") is a mobile phone designed for a rural lower budget market. The handset has a solar cell on the back and is made from recycled materials.[1] It was first released in India on July 10, 2009 with an initial price of ₹2,799.
The feature set is spatial (clock, alarm, timer, stopwatch, organizer, T9 predictive text, calculator, converter, 10 polyphonic ringtones, 5 menu color themes, 3 wallpapers, 2 games (Sudoku and Super Jewel Quest), vibration, profiles, phonebook (500 entries) and call log (30 entries)) .
Additionally it has features especially interesting for a rural consumer market like an LED lamp and power saving mode. It also has support for a built-in phone tracker and SOS messages. No connectivity like USB, Bluetooth or Infrared is supported.
The Indian version also included a proprietary "Mobile prayer", a specialized feature for Indian religions that includes prayers and wallpapers for each as well as alerts for prayer time.
The battery supports up to 570 hours of standby or 8 hours of talk time.[citation needed] It can be charged through the solar panel for up to 10 minutes of talk time per hour of charging.[1] According to the user manual the phone is not supposed to run on solar power alone for an extended period of time.
In 2010, a Samsung E1107 was found as contraband in at the Central Prison at Puzhal.[2] Prison inspectors were also searching for a battery and charger until they realised that the back of the device had a built-in solar panel that allowed it to be charged even while it was being used.[2]
