The charger that came with the phone emits an uneven sound while charging, as well as getting really hot, and it's a bit worrisome. I think it happens more often when the screen is on, and the phone is plugged in. If I remember correctly, fast charging only occurs when the screen is off? But I don't remember reading any explicit warnings stating not to use your phone while it is charging...
This does not happen when I use a plain ordinary micro usb plugged into a computer or regular outlet. The sound really quite loud, I told my fiance to listen to it when it started again the other night and he could clearly hear it from his side of the bed. It's not a sound you would hear from across a room, but it's very audible to anywhere who is near it. It's not even just a steady buzz or hum, I don't really know how to describe it, but it goes up and down in frequency.
Anyone else have this issue? Should I exchange the phone? CAN I exchange it or will they call me crazy? Could it just be the charger?
P.s. can I just say how much of a nightmare this website is to post on?
