Apparently Samsung Galaxy Smartphones with touchwiz are vulnerable to code hack which triggers an unstoppable factory reset. And it can be triggered as easy as dial the code directly in the phones dialer or open it from a website using the stock browser or by accepting the code via an NFC tag, some of the devices that were affected by this hack is Galaxy S Advance, the Galaxy Ace, the Galaxy S II and the Galaxy S III.
Samsung has sent an urgent OTA update for all Galaxy S III devices, and commented on this problem:
“We would like to assure our customers that the recent security issue concerning the GALAXY S III has already been resolved through a software update. We recommend all GALAXY S III customers to download the latest software update, which can be done quickly and easily via the Over-The-Air (OTA) service.”
Although there was no mention about the other devices update, but we can only think that it is on the way to them.
