Major security flaw lets anyone bypass AT&T Samsung Galaxy S II security [video]
BGR has uncovered a major security flaw on AT&T's version of the Samsung Galaxy S II that renders Android's security lock feature completely useless. Using a simple workaround, the security hole allows anyone …
Context & Ripple Effects
BGR's video demonstration lands on AT&T's variant of Samsung's Galaxy S II at a delicate moment for the carrier: AT&T is mid-antitrust trial over its $39 billion T-Mobile USA acquisition, with Google seeking to shield related information, so a marquee handset shipping with a defeated lock screen hands critics an easy data point about the carrier's device lineup.
What makes the finding sharp is the simplicity involved — no rooting or special tooling, just a workaround shown on camera that renders Android's built-in security lock completely useless on this specific carrier build, meaning the protection owners assume they have is simply absent.
First-order effects
- Anyone with brief physical access to an AT&T Galaxy S II can get past the lock screen using the workaround BGR demonstrates, exposing whatever sits behind it — signed-in accounts, mail, messages, stored data.
- Samsung and AT&T are immediately on the hook for a fix scoped to the AT&T build, since the flaw is reported against the carrier's version of the device rather than the Galaxy S II line generically.
Second-order effects
- The disclosure gives enterprise and security-conscious buyers a concrete reason to scrutinize carrier-customized handsets before deployment, pushing the audit burden onto AT&T's device certification process at the worst possible time.
- Rival carriers and OEMs selling competing Android flagships gain a marketing wedge: stock, unmodified builds become the safer-sounding pitch against carrier-skinned variants.
Third-order effects
- If the pattern holds, carrier-specific builds become the recurring weak seam in Android's security model — every carrier variant multiplies the code paths that must be audited and patched separately, straining the update pipeline between Google, Samsung, and AT&T.
- Lock-screen integrity stops being a checkbox feature and becomes a differentiator, pressuring the whole Android ecosystem toward faster, more centralized security patching.
The trend: Android security is increasingly tested at its fragmentation seams, with carrier-customized builds of flagship phones emerging as repeat targets for lock-screen bypasses.
