its C70...has minor screen lift issue, no dead pixels, no speaker problem

mine is C60,
i always listen music loud volume, since it has great battery life i never worry.
i remember that day i just flash to CNA rom, when playing youtube got a loud tud, then no sound.
after i reboot normal back.
same case in post#8 of link below.
http://forums.androidcentral.com/google-ne...aker-blown.htmlafter that incident the speaker slowly got muffled sound and get more and more worst.
but speaker is very easy to replace. i think service center got spare parts.
i send for warranty got back in 3 days.
the speaker prob is not out of the box issue.
better dun always listen at max volume just to be safe
