Cell phone users in San Paulo, Brazil are having problems with their phones exploding. There have been at least five cases in the past two months—all Motorola phones. This is only a problem among a small number of users among the 89 million cellular phones in Brazil.

“In the most recent incident on April 30, the 34-year-old victim in Formosa, Goias state, had surgery for burns on her thighs and arms. She was driving with the phone in her lap when it exploded.”

Exploding phones have been a problem in the past for Nokia as well. As with Nokia, Motorola states the cause is from the use of low quality knock offs.  Motorola officials claim the issue is centralized only to Brazil and that existing customers should not be concerned if they have not already been contacted by the company.
