Almost all Android-based smartphones are affected by a dangerous Android USSD vulnerability. The USSD vulnerability allows any malicious users to wipe completely your Android phone remotely, either by directing you to a URL, or through a text message or scan a QR code or NFC tag linking to the malicious website.

The USSD (Unstructured Supplementary Service Data) codes (a code starting with asterisk *, continuing with hashtags # or digits, which represent commands or data, and ending with a hashtag) are normally used by handsets to communicate with carriers. A common USSD code used by all handsets is *#06# which displays the IMEI number of your device.

Samsung has finally released Android 4.0 Ice Cream Sandwich (ICS) upgrade to the Galaxy S II’s around the world. According to an announcement on the official Samsung Tomorrow blog, the Korean consumer electronics giant will push upgrade first in the European countries including Poland, Hungary, Sweden, as well as in Korea today. Samsung will gradually roll out the upgrade to other markets.

The upgrade is meant for international specification, Galaxy S II (GT-I9100), so if you have any other variant of Galaxy S II, like the AT&T/T-Mobile Galaxy S II or a Sprint Epic 4G Touch, you won’t be able to upgrade to ICS just yet.
