Come there in the settings there is an item of audio, it is already the equalizer to your liking customizable!
But now everything is cut down low in the vocal dynamics to dust and noise, hissing was not audible. A sort of built-in squelch.

accursed poverty does not allow owners to join the ranks, waiting for when he was still cheaper ... and before you know, and the 10-ka officially released.

Take the version from at & t for $ 30-49 (depending on the discount in the store). Details in the topic "buy" link in the header topic.
Known Unlike the regular version, one sim card and 4G frequencies are slightly different (important only for some operators, discussed in this topic).

Well, you need to unlock from at & t operator. This is done for free through their website. Instructions and questions on "SIM unlock devices based on Windows Phone".

And what is it? Type Lumia 640 on contract? Or a Chinese copy? And then his father at work employee bought Lumia 640 50 y. e. I said, "Oh nonsense." Maybe something I do not know? I would imagine also took over 50 y. e.

Not available ... also interested in such a proposal, but the topic seems flashed positions that in the AT & T problem with download speeds ... it was true or not?

About this I have not. I only know that the menu is not select the type of network, 2G, 3G, 4G. And you have to compare the LTE bands with its provider.
