The deceased had used a complex PIN that family members did not know.

Blocked
Case description
A mobile wallet user inherited a phone from a deceased relative in 2023. The phone contained a running Bitcoin wallet app with a visible balance, but the phone's screen lock prevented access. The deceased had used a complex PIN that family members did not know. The phone manufacturer refused to bypass the lock without a court order. A forensics firm was engaged; the device wiped itself after too many failed PIN attempts, destroying the locally stored wallet data. Without the seed phrase, the Bitcoin was permanently inaccessible.
