Nokia 5530 Auto Off During Call Problem solution

if nokia 5530 is getting off automatically during call then you can solve this problem in a few steps that i am going to write down.

Step1: change its ear peace (speaker).
Step2: if with the step1 problem not solve then past a screen tap or striker on backside as shown in diagram above so that it can not be ground.
Actual issue behind this problem is that it got ground with housing (casing).so when we apply striker then it disconnect and become ok.
