Hi. I have a J7 2017 (SM-J730F) since it was released, and there is a problem related to the main speaker that has happened to me several times.

Sometimes, the speaker stops working. Headphones, Bluetooth speakers and the call speaker work perfectly, but the main one doesn't play any sound. Instead, if you listen closely, you will hear a low static noise when something is supposed to be played, and like an electric sound when the sound is meant to be stopped.

If this happens to you, maybe you have noticed that rebooting the phone won't fix it, even in safe mode. But there is a way to make it work again: just turn down the phone and wait a couple of minutes before turning it on again.

If you have other problems with sound and/or other possible fixes for it you can share it here, so somebody may find it helpful.

That is right.
This problem occurs after you do the root.
Power off and wait for a minute or two, then power on is enough to fix this problem.
Note: This problem always occurs when you do soft reboot with a third-party application, but it does not occur when you restart in the normal way.
I liked to share my experience with this problem.
Anyway, thank you.

I've never rooted my phone, and when this happened to me my device wasn't even rebooted. It's more like a software issue, and Samsung must fix it.

But the important thing is that this fix works to everyone, so you're welcome :D
