I've been with the phone for a couple of days, and I do not know if it's my phone's problem or that it's the S9 +.
The volume of the ringing bell and the notifications, still putting it to the maximum, sounds low, I thought it was the loudspeaker problem, but when I listen to music for them, it sounds good and strong, but when receiving notifications and calls I do not know, compared to a XZ2 is very noticeable, not to mention if I compare it with my wife's iphone.
For example, as always in my Galaxy S, I have put as notification tone the bottle openner, because it really sound good and strong, this has been since I had the S6, with the S7, S7 edge and S8 (this less than the previous ones)
Is there a parameter to modify this? Do I look to download other tones that sound louder? Does anyone else have this?
