The newly bought htc new one m7 mobile phone will beep when it comes to QQ information and the like.

There may be many reasons, such as poor contact of sound generating equipment, such as electromagnetic interference caused by poor sealing. For example, Nima, it turned out that you set the message ringtone, ................... Hee Hee, the fastest way. Since it's new, why not go to the store and ask, or after-sales?

I hope this helps.
