i'm not sure how loud it's suppose to sound, but mine sounds pretty low, even the phone's speaker up top seems low as well. Not sure if this can be fixed by a software update or if i should return it for another one. Thing is i already put a screen protector on mines and i don't want to waste time if i get another unit thats the exact same volume or worse. Not sure if this is the case with all the iphones that have been sold. I only have one, so i can't compare or see how loud the 2 built in speakers on the phone are suppose to be... the top speaker, i have it on full blast, and on the other end, my party sounds low, and hard to hear especially in noisy environments... sigh. I don't know what I should do, any advice? and i really need my phone, i dont want to be without it if they decide to ship it somewhere. I just want a brand new replacement if possible. But if i can avoid this all together, that would be even better. Please tell me everyone else is also facing the same low volume noise coming out of their speakers.
