How to properly unlock an FFC connector?

I'm trying to replace a part on my camera and need to disconnect a connector that looks like this:

From what I understand, they're extremely fragile and so I don't want to accidentally break anything (as many others unfortunately did when working on this camera).

Whats the correct way to unlock this connector?

Which part of the connector unlocks? The bottom or the top part?

• Does the light grey flap at the bottom as pictured (away from the ribbon) lift up? Try a gentle manipulation with a little flat head screwdriver to see if it flicks up - if it's going to it won't take much force to do so. May 20, 2020 at 20:48
• Although labeled as zif there are also non-zif ffc connectors, from which you just pull out. If you pull a little on the cable and it comes off, then it is not a zif connector. May 24 at 5:32
