China. A heartbreaking scene was captured by netizens yesterday. A blind man was trying to make a phone call using his smartphone, but his Android device kept popping up with an overwhelming number of intrusive ads that he simply couldn't close. According to witnesses, even when a bystander tried to help him, it was extremely difficult to dismiss the ads. For a blind person, it was nearly impossible to navigate back to the dial pad. The video has since been taken down. Mobile ads. Rogue ads.
