Hello.
Recently I bought a DeathAdderV3Pro in USA, but i’m from Brazil, I bought it on Amazon.com.
Since the first day I’m using it, it is failing the sensor, but isn’t too much, just little failings. Lately, it is failing with frequency.
I’ve done some tests in a software and I’ll anex a pic of the result.

So I need your help to fix it like teaching me how to clean the sensor ou otherwise way to solve the problem.

My aunt live there in USA, so if necessary, I send to you fix it and you send it to her.
I have the proof of purchase
