[NITHIN17]

After the September 2019 security patch update,all the sensors except the finger print,  stopped working in my Galaxy Note 8. Proximity sensor,Barometer,Gyroscope,Hall sensor,Iris Scanner,Accelerometer,all are stopped working. I performed *#0*# test, sensors are not responding in the *#0*# test. I am sure about that all these happened after the security update. Please help me.

I tried a factory reset,run the device in safe mode nothing works for me.The problem is still there.

and if not then flash it via Odin.

The device is under warranty. I purchased this device from Saudi Arabia and now I am in India,so that i cant avail my warranty from India..I googled about this ptoblem and I found that many users are  experiencing the same problem and many of them had motherboard problem afther the update..If things are like that , I have to send back my device to saudi Arabia to avail the warranty which is totally inconvenience for me.

Flashing wont void your warranty as far as you are using the correct firmware. And I dont feel like its motherboard's fault. So flashing is the only option you have.
