Sensor Flex Cable for Xiaomi Redmi 3S Plus

The Sensor Flex Cable / Patta in your Xiaomi is a ribbon cable that carries data and power signals from one or more sensor modules — which may include the proximity sensor, ambient light sensor, accelerometer, gyroscope, or other onboard sensors depending on the Xiaomi 's sensor architecture — to the motherboard. When it is damaged, all sensors routed through this flex cable lose communication with the motherboard simultaneously on your Xiaomi .

If multiple sensors stopped working together — particularly after a drop or after a repair involving the top of the phone where sensors are typically located — the Sensor Flex Cable / Patta is the most likely common cause. If only one sensor fails while others on the same flex work normally, the individual sensor module may be at fault on your Xiaomi .
