Desire HD Proximity Sensor Problems

With the release of the long awaited HTC Desire HD also came an annoying issue, which has been plaguing quite a few people - some having better luck than others.

From my own personal experience, and from what I've read from others, the main problem starts when trying to make outgoing calls. Depending on the lighting conditions, the screen will go black and stay that way.

If you happen to get an incoming call, the screen doesn't go black at all - even if you put your ear to the phone. So, this is only an issue with outgoing calls. This leads me to believe that it's a software issue (thankfully), and can be corrected a lot easier, as opposed to hardware issues.

After playing around with it a bit, here's what happened in different lighting conditions:

Good Light

I dialed the number and a couple seconds before even putting the phone to my ear, the screen went black.

Poor Light

I dialed the number and as soon as I put the phone to my ear, the screen went black.

In both of these lighting conditions it continued to stay in it's black screen state, and it wouldn't wake up from that.

How to get out of the black screen
  • Take the battery out, put it back in, and then start up the phone.
  • Plug in earphones - although, these didn't work for me when I left it in the black screen state for an extended period of time.

I personally got my phone yesterday evening, and after reading all the threads, it put me off a bit, but still took the risk and got it anyways. It didn't surprise me that mine was having the same issues, but I'm determined to find a fix, or at least hoping that HTC come out with something quick.

I'll post some videos of my phone and show you what it's doing exactly.

*** UPDATE ***

It seems that phones starting with the following serial numbers seem to be affected:

  • HT0A3RX
  • HT0A4RX
  • HT0A5RX
  • HT0A6RX
  • HT0A7RX

If you have a phone with this problem which has another serial number, please let me know.


There are some reports now that say blowing on the sensor fixes it.

And if you're wondering, the sensor is to the right of the big speaker at the top of the phone - here's a video to show you.

Alternatively, could of been a silent OTA done by HTC (hopefully). If it is an issue with dust on the sensor, then that's a serious design flaw

I brought my Desire HD yesterday. The battery was half full, and hence I decided to use it. But everytime I startup from standby, after few seconds of navigations, the screen woulg go blank. I tried few times to put to standby and switch it on and it worked for 1-2 times. Then it will indifinetely go into the blank state. Then I had to remove the battery and put it in again and then restart. Then it is ok. But the problem still persists.
When I approached the Service Provider yesterday evening, he suggested that it would need a full 8 hours initial charge.

But I don't this it really helps.

Too much disappointed to see such a flaw missed the QA of a innovative company which is a leading in touch-flo.

I hope my service provider would replace the piece for me.

b.t.w. my phone serial no. starts as HT0C1RX.

Just downloaded firmaware version 1.32.405.3 over the air and it seems to have sorted it.

Mine HTC Desire HD has this issue. The HTC software update didn't help. Blowing on the sensor helps only for a while. The problem returns. I read that it could be a hardware issue - people say that dust can go into the sensor and it cause the issue. That is why blowing helps. But this should not happend in such expensive phone! My serial starts from: HT0A8RX (Europe, Poland) I think I will return the handset back to the store. I doubt any software change will help.

download the OTA update from HTC. fixes it. and since they fixed it by 'their' release date, no one can moan really.
