Absolutely loved my phone when I got it a month ago but now I’m getting the classic common crackling when on the phone even if change to speaker. Happens on and off. No moisture and I clear it of dust. It’s always been in a case and not been dropped. Looks like it needs to be sent off and sorted yet my old phone started to play up so had to get a new phone.the only thing I like about the S7 is the picture quality and the phone over all design else the nothing special in the market.
