So it finally happened..........I got the proximity sensor issue on my DHD :(.

To be honest I'm convinced it is a hardware issue as my first DHD had absolutely no issues at all and was well built. This new device, as soon as I looked at it I could clearly see a gap between the screen and top aluminium housing. In certain light I could also make out a gold/brass circle in far right corner (not near the sensor....right in the very corner). Also, as I stated in another thread, the power button seems much more sunken into the aluminium housing (not as prominent) and is actually a little difficult to push.

Today I got the problem and blowing temporarily fixed it. I will post a video next time it happens.

I really think its an issue with something getting trapped in the space above the screen, near the sensor.

OK, I dont know if this is related to proximity senser:

The selling feature on DHD that silence the phone when u put it facedown is not working on mine.

It worked the 1st time I set it up, however, when I call the phone while facedown, the phone ring nevertheless.

This is annoying as this is one of the feature that made my buy this bloody phone. Now i m going to wrry about this thing going off in meeting!

Ok I live in Ireland and I received my DHD last Tuesday the 26th and I had no issues I did the update as the day after I got it. Then today I was on the phone to my wife and when I took the phone from my ear it was black I was able to get the screen back by pressing the power button I then put the phone back up to my ear then when I took it down it was black again. This time when I pressed the power button if flicked to the correct screen for a split second and back to black. Each time this I pressed the power button this happened and I could not end the call. Eventually it stopped and the screen came back.

I rang vodafone Ireland today and they are collecting the phone tomorrow.
I came from a 3GS to this phone and I never had an issue I was strongly thinking of changing to the Iphone 4 after this.

But then my new silicon cover arrived in the post today and its lovely and great fit and Id really love to keep to keep up I am unsure what to do now.

All sound like symptoms of the same initial bad batch of these handsets that my first two (yes two) have come from. Waiting on No.3 from the next stock for Vodafone. Have you had a look at the camera to see if it is off centre and probably lower set than it should be? My first two had all the usual suspects, camera too low, SIM cover doesn't fit flush, first one had a decent sized gap at the top and one side of the screen, the second has a loose camera bezzle. Most of these issues point to the inners of the phone being misaligned with the chassis. We might only be talking 1 mm here but that is enough to throw the whole handset out of line.

Yeah exactly all those issues, camera/screen gap/battery cover/power button.
This is why I believe its a hardware issue (or misalignment of some type). My first handset was perfect, no problems at all really - it's a pity I cancelled that contract and kept this vodafone handset

Although I may actually be getting this for free as when I cancelled my other contract (with VF through mobiles.co.uk) VF cancelled my entire account including details for this handset, so I'm sat here with a DHD, unused VF sim and no VF account ! SSSSSHHHH !! :D

......now to figure out how to get it fixed without contract lol

has anyone tried pushing the insides up ?? like taking the sim cover off and forcing it forward maybe it isnt all the way in cause when they make these they slide the board from the bottom might be worth a try ?

i havnt got mine yet ill be in the next batch from handtec arriving sometime week commencing the 8th. but from what people are saying it sounds like the sensor is picking up another part of the phone on the edge of the sensor sometimes

im also going to be part of that batch. I plan on asking Handtec to check if the DHD they are going to ship to me is fine before they dispatch. I'll try describe all the signs, like camera offset, small gap between body and battery case, power button deep in the case..etc

Im really disappointed in HTC's build quality of this phone.

mmm im thinking i might do the same last thing i want is for it to arrive here in Australia after waiting this long only to send it back for replacement, im sure they would be more than happy to check it if it means less returns

however if it can be fixed yourself by pushing the innards up yourself then its less of an issue, however we have to wait for someone to try it

That happened to me - it lasted a few days and now it's back to normal. HTC have said there's no update to address this right now and advised exchanging the handset. I guess I'll have to do this - if the blowing into the sensor trick stops working later we'll be up s*** creek

I'm with you guys. Waiting to send mine back to Handtec. I'm sure they've dispatched all of their first batch but who know's if the 2nd stock intake is ok. I'm in Aus too so really not wanting a repeat of this but will retailers really open the packaging and test the phone?? Even the good phone's have the problem until the OTA is done right? I really wish they could check the phone but I don't see how they can do this for us..

if you authorize it i see no reason why they wouldn't, many still dont have the issue with the ota still if it is software id rather get one with perfect build.

there was another poster who asked handtec to do similar with his and he got an email back saying they would. i doubt they will 'test' it but they will look over the exterior for build issues such as the offset camera or gap in the sim cover ect...

if there is one that is not right i would imagine they would send it back to htc and if its fine mail it to you after all you asked them to break the seal so you cant sent it back saying its open im sure they would log it.

but you are right they wont 'test' it by making a call ect this is purely to inspect obvious build quality issues

on a side note have you tried to push the inside piece of the phone up ? if it seems too low ie offset camera low power button

Just had a confirmation txt that No.3 is to be dispatched today for delivery tomorrow. Will report back tomorrow if this batch is of better build quality and without the previously documented issues (hopefully).

    Hi Sanju,
    Dutch indeed ;-)
    Both cover on the back and screen on the front now are nicely placed. No gaps whatsoever. No proximity issues either ::)

    Bought my phone in a Vodafone shop. Swithed it two times (this is my third Desire HD) and they didn't make any fuzz about me replacing the handsets. Which is worth a compliment indeed! I even changed the second in a Vodafone shop at the other side of the country.

    Regards,

    Let me tell you, by following that guide and getting clockwork installed you've already made huge progress.

    1. Yes you can restore everything. But it will only restore it to the point when you made the backup. So after you rooted and s-off. If something goes wrong with your phone and you want to send it to HTC then you'll need to restore that backup and also remove root and s-off. There are easy ways of doing this but you should worry about those things only if you need to send your phone back :) No need to worry though because things will work out :)

    2. Yes it will include default apps. Absolutely everything, you phone will be restored exactly how it was before updating (apart from the radio if you change that).

    3. You can use rom manager yes, but as far as i can tell rom manager only allows you to flash Cyanogen (at least in the free version of rom manager). Other ways, and in my opinion the best way, is to download a rom from these forums in the dev section, and flash it from clockwork. Always make a backup before flashing, just incase something goes wrong, although nothing will probably go wrong.

    4. Yeah this part sort of confused me at first. What i understood was that if you update to version 1.72, this update installs the update as well as a new version of hboot (this is the bootloader). It is this new bootloader that prevents from rooting, s-off etc. But the leedroid rom only includes the new update, and retains the old version of the bootloader which is rootable.

    5. My phone never had this problem. I got it when it was on the same software version as yours and never saw it, i then installed leedroid with the new update 1.72 and still havent experienced it.

    Ok i will send you a pm because i think we've taken this discussion a little off topic :)

    hmm that is weird. as soon as the second ota update came out (which supposedly fixed the issue) this thread died more or less. i thought it would have been solved. i personally havent experienced it. Have you tried a factory reset?

    edit: just realized, you're not running the latest firmware. your build number should be 1.72. Go into Settings>About Phone>System software updates and check now. Maybe that could solve it.

    edit2: keep in mind that you'll lose root by updating, and wont be able to root using the current methods.

    Thanks for your reply mate.
    I tried but I got this message:

    Your phone is up to date.
    There is no updates available for your phone.

    1. Is it due to my version is South East Asia version which contains English, Chinese, Thai and Vietnamese input?

    2. Do I have to unroot before checking for updates?

    3. You mean version 1.7 is not rootable yet?

    4. Any advice if I use other ROM? Any suggestion?

    Thank you.

    1. Yes it probably is because of your location. The update was only released for Europe.

    2. I'm general you don't need to be unrooted. It will still tell you if there are updates available

    3. Yeah I believe it is not rootable yet.

    4. I personally am using leedroid. Very nice Rom imo. The latest version is using 1.72 base and is fully rooted.. perhaps if you flashed this your proximity issues might be resolved. Keep in mind you need to be s-off and perm rooted to flash roms.. with clockwork recovery installed.. but more on that in the dev section.
