[HTC Rezound] SpyderWeiss:
Sent the following email to HTC and here's the thread that follows, thought some people might be interested in this:

My Rezound is having a weird high pitched whining sound in the background whenever the capacitive buttons are lit up on the bottom of my phone. So if I'm outdoors in a sunny area, I have no problems, but if I'm using the phone in the dark, I have to turn off the screen (which turns off the lights on the capacitive buttons), and then the whining goes away, but obviously this doesn't solve the problem if I need to use the screen. Is there any way to turn off the lights on the capacitive buttons using a menu option or something? Also, have there been a lot of reports of this whining noise in the background?

Thanks!

(I found out how to resolve the issue, I installed a custom ROM that allows me to change the brightness of the capacitive buttons, and the problem has gone away).

HTC-

Thank you for your response. I am glad to hear that you resolved this issue, however it is unfortunate that it took you a custom ROM to do so. I can confirm Mike that HTC has identified the issue of the high pitched noise on the HTC Rezound as a software issue that will be corrected with the next update. This issue is presently being investigated and our developers are working hard at creating a maintenance release for this device. Because you now have a custom ROM you will not receive a direct notification when the FOTA (forced over the air) update gets released. When the update is made available Mike, you can check our web site at HTC from time to time to see if it has been released as a manual update for your phone, should you want to return to the stock OS. The backlight of the keys is also something that some of our users have asked about. I will pass along your feedback on this issue to our developers, and it's possible that in future updates there may be an option to disable the backlight manually using a menu option. It's definitely a good idea, so I hope that this becomes a standard feature in future models from HTC. If you need additional information on the Rezound, you may wish to check your user manual from HTC . Please use the binocular icon on the left side of the manual to enter key words. Using this method helps you to locate all references to the topic you are researching. I deeply regret any inconvenience this may have caused, and I hope that your custom ROM allows you to continue to use and enjoy your HTC Rezound to its full potential. Please don't hesitate to contact us again with your technical questions or for issues you may have with your phone. We are here between 6am and 1am EST, 7 days a week for your convenience.

I don't think it's unfortunate I had to use a custom ROM to solve the problem, but I understand what you mean by that. I still hear the noise when the screen comes on or goes off, but at least it isn't constant now. I'm glad to know that HTC is aware of the issue though and is rolling out a fix in the next update (which I'm hoping will be the official Ice Cream Sandwich update). Also, being able to control the backlight on the capacitive buttons is really awesome, even if it wasn't the solution to removing the high pitched noise. It's great when I'm watching Netflix at night in bed and I don't want the lights to distract me from what I'm watching, I just put it on the "dim" setting. I am extremely happy with my Rezound, I'm really hoping that Google allows HTC to make the next Nexus phone, because I know you guys would make something awesome (unlike the current Galaxy Nexus which has a sub-par camera, non-removable SD card, and cheaper construction in comparison to the Rezound). HTC has won a long time customer, I can't wait to see what you guys do next!

Thank you for your feedback. I am glad to hear that you are happy with the solution you found, and that the new Ice Cream Sandwich features are proving to be useful on your Rezound. I have only had a brief look at ICS on the HTC Vivid, and I like what I've seen so far. Overall the improvements seem very user friendly. I am also hopeful that ICS will be the next update pushed for the HTC Rezound as many of our devoted fans are anxiously awaiting this software upgrade. Like you, I hope that HTC will again partner with Google for the Nexus line. The original Nexus One, though not as new as the Galaxy, continues to be a fan favorite among many HTC and android enthusiasts.
