Buzzing Sound

[apj]

I just got my Moto Q 9 from At&t, and notice a buzzing / humming sound from the phone when the keypad lights are on. Its kindof noticeable but if you put it to your ear while the lights on the keypad are on, you can really hear it. Does anyone else have this problem? Is it a bad phone? I did a powercylce on it with no help. I have not even got to add the service to it yet because by time I got out of work they closed.

So it is Normal? Should I have them send me a new one?

If you do some checking and im not mistaken, the Razr v3 had the same issue. Moto said this is normal operation...

its normal...i didnt even notice till someone brought it up here. terminates when the keypad lights go out.


you all got some good hearing.

I did do some looking this is what i found about the Razr, so i guess it is normal. I just thought maybe it would have been fixed by now, or that i got a bad phone.

Product Note: Motorola V3 RAZR Keypad And Speaker Noise -All Markets
(COR, DMDR, Indirect Internal/External)
Some users of the Motorola V3 RAZR may hear a hum or a high pitch tone emanating from their device at certain points during use.
(Mon, November 07, 2005)
Issue/Volume number: 1

OVERVIEW

Both of these sounds can occur as part of the normal operation of this device and are NOT an indication of a problem or defect in the unit.



NOTE: No warranty exchanges should be executed for either issue if consistent with those that occur during the normal operation of the device.



CRITICAL, MUST KNOW/MUST DO

With normal use of the device these sounds are commonly heard when:

* (Tone) The phone is held near the ear before making a call. When a call is active the software in the phone changes the frequency of the tone to one at or below the low end of the normal audible range (Please note that persons with sensitive hearing may still be able to hear the tone).
* (Hum) The keypad is held close to the ear (much closer than in normal calling position). It is due to the inherent properties of the electro-luminescent backlights used in the product.



Customer / Embedded Base Resolution:

If a customer requests assistance or an exchange due to the buzz or high pitch tone from a V3:



1. Verify that noise or tone is consistent with normal operation by:

A. Tone in speaker: Verify the tone is eliminated or reduced to a non-distraction level by placing the unit on a call and listening via the earpiece speaker.



B. Keypad “hum”: Listen to the keypad when the backlights are active. Wait until backlight times out. The “hum” should follow action of backlights



If you determine that the sounds are consistent with these known occurrences, NO exchange is warranted.



2. If found to be inconsistent with normal operation, then proceed with standard troubleshooting / exchange processes.



ACCOUNTABILITY/RESPONSIBILITY

Identify customers impacted by this issue and follow appropriate procedures.

I think it is really loud on mine plus i have a skin on my phone so it kindof made it vibrate a bit

I didn't notice the buzzing until I read this thread and was talking on it last night when the backlight was on. It is definitely noticeable. Does the other party hear it as well? Time to call myself...

lol I just put my phone up to my ear. sure enough it made a humming noise. I've had this phone (Q9c) for 4 months and this is the first I have noticed it . I had no problems with it. it must be normal.

I can here mine when I put it on my bed side table an night. I'm just glad it doesn't do it all the time.

And if you notice the sound comes from the keypad only.
