Magnetic Sensor not working after screen replacement - Solved
Dear All, my phone was out of warranty so got the paid screen replacement done at Samsung service center and now the magnetic sensor is showing zero readings. I have asked them to do the firmware refresh but still it didn’t work. I claimed that it was working fine earlier but service center denied saying it’s motherboard issue and need that replaced too. Now, it will be a fool decision as combined cost of Screen and Motherboard will exceed the new device cost.
Please advise if there is circuit or connector which can get damaged or not properly fit during screen replacement which can affect the magnetic sensor.
The device is using Asahi Kasei AK09916C Sensor
As an update, the culprit was the faulty AK09916 3-axis electronic compass IC and with high level of customer support, Samsung agreed to replace the PCB free of cost. Thank you Samsung India!
