As I wrote in another post my phone came with defective speakers - both the loudspeaker and the ear-speaker are sizzling terribly and I am unable to use the phone normally - only with headphones or with a bluetooth headset.
I contacted the AliExpress seller and he promised to solve the problem but then stopped answering my messages.
I went to a service center and they told me that they can replace the speakers but need original ones. Where can I buy original speakers for replacement? Thanks.
