proximity sensor error

[ajayyv]

I am using C9 Pro from last 6 months n there was never any problem with the phone but suddenly Why I am getting errors on the lock screen about proximity sensor and in the Sensor Test I can't understand anything, can someone please see the attached images and explain all this to me and how can I fix this

[ritvhik]

this isn't an error ,it happens when you face the phones back and it's touched accidentally

I don't have a c9 but I don't need that phone to understand your problem. here is what you need. turn off that option in screenshot. proximity sensor is being blocked. Either there is dirt on sensor, scratches on glass. there will be a rubber or plastic ring around the sensor it some times moves over the sensor when phone hits the ground very hard. take your phone to service centre.
