London, July 3 Land Rover has unveiled what it claims to be the world's strongest phone, after the gadget survived being dropped from a tall building, stood on by an elephant, and roasted in an oven.

Called the new S1 mobile, the 'indestructible' device was developed after the car giant teamed up with phone manufacturer Sonim.

During durability tests, the phone was run over with a Land Rover, submerged in mud, and had an elephant stand on it.

Aimed at appealing to builders and workmen, the S1 features up to 1,500 hours of battery life, a 2.0 megapixel camera, and an extra loud ringtone to be heard over the sound of heavy machinery.

Tesco launched the phone with a price tag of 249.99 pounds, and are so confident it can't be broken that it comes with an unconditional three-year guarantee.

However, staff at British tabloid The Sun managed to crush the S1 under the weight of a three-tonne forklift truck.

The phone, however, did survive being roasted in an oven at 150 degrees centigrade, soaked in a pint of lager and tossed from the second floor of a building. (ANI)
