Problem

Service is aware of an issue, identified during field return analysis of the GSM

V600/V600R product, where pressure applied to the flip at hyper-extend can result in the ‘Lazy Flip” failure mode. See image below. The root cause is that the hinge cam, in the flip closed position, is not able to provide sufficient force to keep flip closed tight to the base. This allows the flip to open if phone is turned upside down. Severe cases, when used in an active use-case, may lead to customer returns for display flickering due to over cycling of the flip detect switch.

Fig. 1.0 - Flip falls away from base, creating a gap between the flip and base bumpers

Solution

Adjust double D feature in right knuckle (P/N 1588188N01) to optimize hinge cam position.
