It's important to note that ZIF connectors often do require force to insert, for example the digitizer ribbon cable on the Nexus 6, which has a bit of negative tension from being curved. It has to be pushed in using the little raised portion with a fingernail, and held so the line on the cable matches the line on the PCB before closing the retention bracket or else it will not connect properly.
