In December 2019 I bought a Huawei P20 phone new in EuroAGD,
after three missions, the microphone works worse, the voice is like a well, they complain that they can't hear me at all. The loudspeaker began to grunt.
Earlier I had P10 and it was trouble-free, and with P20 I join the group of dissatisfied customers. I'm afraid to think how it works the lower models of this company since the top model can not last even 1 year without failure. I see that the company goes down with the quality of its products. As I read people's opinions about the Huawei website, I am afraid to give up my phone ... maybe I could sell it better and change the brand. What do you think about this?
