According to a study in the ultra-conservative Muslim kingdom over 70% of files exchanged between Saudi teenagers' mobile phones contain pornography.
The study quoted in Arab News focussed on the phones of teenagers detained by religious police for harassing girls.
The same researcher also found that 88% of girls say they have been victims of harassment using Bluetooth technology.
"The flash memory of mobile phones taken from teenagers showed 69.7% of 1,470 files saved in them were pornographic and 8.6% were related to violence," said report author Professor Abdullah al-Rasheed.
