Honest answers
Guides
People lose hidden photos every day — to updates, phone changes, one wrong tap — and most of what ranks for their distress either dodges the truth or sells them recovery software that cannot work. These guides do the opposite: the honest verdict first, a decision tree you can follow in a minute, and prevention that actually holds. Every claim is labeled sourced (official documentation, linked and dated) or reasoned inference (our technical analysis, marked as such) — and every page carries a changelog and gets re-verified after major OS and app releases.

The one question that decides everything, three cases, and why recovery software can't reach app-private encrypted storage — plus the five rules to never lose hidden photos again.
Samsung Secure Folder: photos gone after an update or new phone?
Update bugs vs permanent loss — and the Smart Switch transfer question Samsung's own documentation leaves unresolved, with the only rule that's safe under both readings.

Der ehrliche Entscheidungsbaum auf Deutsch — was noch zu retten ist, was nicht, und die fünf Regeln, damit es nie wieder passiert.
The method behind these pages
No affiliate links, no recovery-software funnels, no vendor bashing. When photos are gone, we say so; when they're recoverable, the steps come first and cost nothing. Whatever vault or hidden folder you use — including ours — you can check it yourself with the five-minute verification, and read exactly how QuietStor is engineered in the security model. More guides are on the way; each new one appears here.
