It worked but was faulty (it had artefacts on photos and videos) so I asked for a replacement and he sent one. It had even more artefacts, I'm almost certain he's selling used parts as new but that's another issue.
Anyway, it's tough to find an i9505 camera at a reasonable price. But would this do?
