Yes. testPod securely wipes locked Samsung devices that several competing tools can't handle — it's a big reason recyclers switch to us. One recycler processing roughly 10,000 devices a month moved to testPod from Blancco specifically because we could wipe locked Samsung stock they otherwise couldn't clear.
The wipe follows the NIST SP 800-88 method and is ADISA AAL Level 3 certified, so each device gets a certificate your compliance team or ITAD auditor can rely on. See certified erasure certificates.
