In Xiaomi Redmi Note 4X I can not hear my interlocutor very well.
Problems started recently and the phone is under warranty. During the conversation after a while, the interlocutor I hear as in the basement. The sound constantly goes down. Repair the phone is not possible, and the store refuses to accept the goods without protective labels. Where to deliver this phone for verification or replacement? Will the delivery company accept it without labels? How else can the problem be solved?
Esta é uma boa pergunta?
