Proximity sensor failure

My DHD has problems with the proximity sensor. I returned the device to the vodafone store (Netherlands), and they changed the device for a new one that worked.
Today, 1 day later, my second DHD is now having the exact same problem with the proximity sensor.
When I make a call, the screen immediately goes black, and the device no longer responds to any button (not even the power button on top). The ony way to get the device back to life is by removing and reinserting the battery.
Video of the problem
When I receive a call, the screen stays unlocked, even when the device is placed against my ear, so I end up with my ear pressing the active screen....
I've read more complaints about this exact problem on the tweakers.net forum. It is still unknown whether this is a hardware of software failure.
UPDATE
The problem seems to be related to the lightsensor, when holding a locked DHD in front of a bright light source, the device wil unlock (as long as you keep it in front of the light).
It might be, that when used in bright daylight a DHD will function properly.
Also, when calling using the headset, the problem does not occur. When inserting a headset in a "locked" DHD, it will wake up.
UPDATE2
Some facts, to "bust" some myths about the problem:
- It seems the problem can happen on all DHD's, not just devices with a particular S/N, software version, carrier (telco) or color.
- It has something to do with the light sensor (which is the same sensor as the proximity sensor) since the device unlocks when held in front of a bright lightsource, some users claim their device works well, as long as they are in daylight.
- The DHD uses a CM3602 proximity/light sensor, the same as a regular Desire
- The problem might not occur immediately after purchase, sometimes it takes a few days before it starts, thus switching your DHD for a new one might only solve your problem for a few hours/days (this is what happend to my second and third... yes third device)

Seems like the same kind of problem: http://forum.xda-developers.com/showthread.php?t=811282

Exactly the same post. Nice detail that I'm also a Dutch user bought it at a Vodafone store.

So, that's at least 3 devices reported with this problem.
Is there a way to turn off the proximity sensor? This would mean I have to turn the screen off manually when I make or receive a call, but that way, I don't have to reset the device every time I make a cell

Maybe you guys have found why it failed the google test ?

1-2-3 from the first stock - that is an failure that will come back to all of us...
did you try contact HTC ??

I wouldnt be very worried tbh, this is surely software related else they wouldnt release any batch of cellphones and delay the release for more than just a few weeks.

Can you make a Video and load it up on Youtube?
If we have a video it´s much easier to show HTC the problem... maybe we can load this video up on facebook to the HTC page...

Really bad if this failure concerns all DHDs. But why 3 devices?
I only count LeonM1234 and WizardX?
Edit: Ah I see 2x LeonM1234 and 1x WizardX. Forget this post

This is my second DHD with this problem
P.S. Can any mod please remove the 1 post per 5 minutes limit, it is quite annoying... thanks!

A lot of HTC phones have a similer problem. Its S/W related (the desire had it when it was first out e.g. it the screen used to go black and not re-light untill you placed it on a table or the other person hung up)
I would be suprised if 3 phones have the same fault unless it SW related :-D

HTC's new Windows phone seems to have a similar error with the proximity sensor:
As I'm a new user I'm not allowed to post a working link. I try to write it so the system accept it.
www . techeye.net / mobile/one-day-after-launch-event-windows-phone-bug-spotted
If this turns out to be true it's more hardware related than software, isn't it?

i think to cancel my DHD order until that issue will check.

Yep was solved with a S/W update

You can add one more to the list. Friend of mine had the same problem with his proximity meter. I will receive my D-HD either tomorrow or the day after, I'll let you know if it works properly.

Tile homepage / lockscreen bug

As of late I've noticed that when I wake up my device it'll take me to my tile homepage, then quickly forward me to the lock screen where I'm prompted to enter my 4 digit pin. This never happened before and I'm wondering what's causing this.
Has anybody experiences this?

Yes, it's a tiny glitch that flashes the home screen then the lockscreen. Personally I had this with Windows Mobile 6.5, and it really bugged me.
Sad to see it here with WP7.
Maybe future updates will hopefully fix it?

Thanks for the reply. I figured it was a glitch. Hopefully it's fixed with an update. Ot only just started happening yesterday, and I've had my phone for about a week. :-(

Doesn't happen for me... although, after reading this, perhaps I should add "yet"!

It does not happen to the stock lockscreen wallpaper ... but when I change it, it jumps from the home screen to the lockscreen, hm

Weirdly enough, I got a Focus that had this same bug and it drove me crazy. However I had to return that Focus because Wirefly was threatening to charge me $300 if I used it on a different line on my family plan.
So a couple of weeks later I picked up the Focus from AT&T for the $99 price and now I don't have that bug! It's weird really...

Do you think this could be fixed with an update?
I had something similar happen with my HD7. Instead of flashing to my tile homepage, it would flash the color green. Then it would take me to my lock screen.

Did you do a factory reset?
My wallpaper is still glitchy too, but not as much. Maybe like 1/2 a second.
Edit: Don't factory reset it if you didn't! I'm just asking if you did

I tried a factory reset the other day and it didn't help.
I just really hope that it's not the phone itself that's messed up.

I don't know if its the phone itself, but some people claim that changing phones helped. Most of the videos I've seen on Youtube with Windows Phone 7 apparently don't have this problem though.
For me, I have an HD2 and I've been switching WP7 rom's regularly. Of all the ones I've tried, I seem to have this problem.
My brother, who also has an HD2, claims to not have this problem.

Unfortunately, changing phones is not possible, as I have an unlocked Omnia 7 and the grace period for exchanges has passed.
It's a shame because I really love this phone and OS, but this bug is ANNOYING. It kills the experience.
If anybody else is experiencing this, please respond!

i guess your last hope is the upcoming update... hopefully it fixes it (and a lot of other bugs).

Video of the bug that I'm describing.

This user (who uploaded this video) is also having problems with his Omnia 7. It's the same bug that I described.

I'm having this problem too, but I've found an easy way to fix it (at least on my Focus). Whenever I have the brightness setting on low or automatically adjust, it goes away.

Lockscreen bug
Hi all,
I have samsung omnia 7 and i am getting this lockscreen issue
Code:
http://www.youtube.com/watch?v=isi5aKDjnws
I would like to ask if some of you with different devices are experiencing the same or is it just with OMNIA 7??
This issue appears only if you have automatic brightness turned off..

There's been a few topics created about this. I believe it began because of users using PINs and wanting their information to be protected... That obviously has a bit of a security flaw. I'm sure it'll be fixed in the update.

Hi, i can also confirm this issue on my omnia 7. Fix is as described to turn on automatic brightness.. However, i would like to ask if this is WM7 bug or Omnia 7??

Have there been any updates to address the multitouch issues?

Drives me up the wall. Sometimes it's good and sometimes it's not.
Sent from my Nexus in Texas.

Aha. Well well.
Care to elaborate?

The multitouch issue were "multitouch" becomes wonky (for lack of a better word), after periods of use. Best example: playing a game that uses multitouch. The only workaround right now is to turn the screen off and turn it back on. The software resets when screen is toggled on/off. THIS IS A SOFTWARE PROBLEM.
I believe it's still an issue. I still have the problem on 4.0.3.

Multi-touch problems? Not on my phone. First i've heard of it.

You probably just didn't notice it. I didn't know about it until i read about it. Then i tested for it. Lo and Behold i had the same issue. It's probably a non issue to some people. This happens on any version of the GalNex
You will not see it until you play a game then test for it.

I have the multi touch in the bottom corners. It's an on/off and turning screen off temporarily relieves. It hasn't been a big problem, because I don't game often but just wondering if anything is on the table yet. I know it is software so it is easily fixed. Has anybody come up with a patch for it?
Sent from my Nexus in Texas.

Is there something in the OS that can invoke this bug to occur? I have a stock unrooted and locked bootloader GSM GN and when I had 4.0.1, I never had any of these multitouch problems on any game that I played. Now with 4.0.2, this problem keeps appearing. It's really annoying

I just tried to do same as the guy in the video.. Everything is fine at my phone...

Playing ShadowGun and Riptide GP on mine produce this issue, and turning the screen on and off works for a few seconds, then it happens again.
Waiting on a fix here too.

You guys should go here --> http://code.google.com/p/android/issues/detail?id=23044 and star this as well as leave a comment. Hopefully this will help get the ball rolling. It's happening across every model of gnex. I think that it's almost impossible that google doesn't know about this yet but whatev, can't hurt.

[Q] touch key lights bug

hello everyone , so i use to have this bug back to kitkat also but it wasn't happening as often as it doesnt now that i have lollipop rom installed on my galaxy tab s T705 , the issue is with touch key lights which stays on even when i have them always off from settings , they act super weird when they are in that mode , they go off few sec after screen is off and if i shake the device they go on again as it looks like they are connected to accelerator sensor or something lolz ,the solution is super easy tho just hit the power saving on and then off again and they work normally again i heard some other ppl dealing with same issue but i wanted to know if there is a perma solution for it or not , im sure its a software issue but is there a way to fix it ?

Install a custom rom like cyanogen or something stock based.

I have the same problem. I usually have it set to turn the lights off after 6 seconds, but after a couple of days they don't work anymore. I would change the setting to off, then on, then back to 6 seconds, and it'll work again. After a few more days, they stop. I haven't seen a permanent fix for this.

Same for me. Would usually opt to have the buttons backlight always off, but randomly it starts actin like always on, although the settings remains 'always off'. Toggling the setting to anything else and back to always off fixes the problem temporeraly.
Im running stock swiss lollipop on my t700.

Yes, this is driving me nuts too! I hope they resolve this in the next update and soon!

Same problem with the lights on after a while even though set to always off. Seems to work properly under 1.5 sec setting option. I would love for the lights to be always off though.

Me too have the touch key settings to always off and found the same problem.
In my case I think it only happens when I plug the Tablet to AC.
Did this happen to anyone under another circumstances?
Thanks in adavance!

I have the same problem as everyone else, which I am very "happy" to hear because I am not the only one apparently dealing with it. I purchased the tablet a couple weeks ago and noticed that even though the setting for the touch key backlight is "always off", it goes on when I open the case, and sometimes goes on and off and goes weird. I contacted Samsung and they requested that I send in the tablet for repairs, so I did. At the same time, I contacted Amazon and they sent me another Tab S tablet. I have a month to return the other one so I figured I'll try this second one and see if I continue to have the same issues like the first one. Sure enough, I had the second tablet for less than a day and it's doing the exact same thing! So far the 1.5 second setting seems to keep the darn lights off. Sometimes doing a soft reset will fix the issue temporarily, but not permanently. If anyone figures out how to fix this, let us know! I'll be following this thread. I hope there's a software update to fix this.

I believe this is a software bug so all tab s running the 5.0.2 lollipop will have this issue.
And to reply to the other poster: The problem will occur after a while, the lights will just turn on and stay on when you wake the tablet. Changing the setting and choose Always Off will fix it but it will come back after a while.

Is there a way to get it back to the stock ROM? I'd rather avoid this light issue until an update to correct this comes out. Thoughts?

I heard that there's a new update available for the Tab S. (I already returned my tablet before my 30 days to get a full refund.) Did any one get the new update, and if so, did it fix the issues like this touch key light?

Hey,
I had this problem on the original KK software - upgraded to Lollipop a few days back and I still have the bug... in fact, it is even worse! Occurs more frequently than on LP.
I wouldn't mind leaving the lights on all the time, but they're so damn BRIGHT, and there's no way to adjust the backlight intensity!
Cheers,
Su

I found this solution on another forum...
If you enable smart stay, the touch key light duration will work properly.

Any further movement on this?. I've found that if I take my tab out of the book case the problem goes away. Seems like it's a bug with the case sensor.

No movement that I'm aware of. I'm really frustrated that there hasn't been a fix after all this time. I'm holding out hope that if there is ever an update to Marshmallow, that the issue will go away. Interesting observation about the case -I have a book case on mine. I'll remove it and see what happens...

Ambient Display Screen Flashes

Hi Guys!~
Hope all is well !!
... recently I came across my rooted android 11 Pixel 3XL got a screen flashes with bright home screen background during the screen turning off and entering ambient display mode.
I try my best to find a solution but haven't found one yet.
I have tried to reflash to stock, also doesn't fix the problems.
... the only solution I found at this moment is to get android 12 beta which the transition animation from turning off the screen to the wake up of ambient display is totally different and I still prefer to stay with rooted android 11.

If you tried multiple roms especially the stock* one unless it's something you loaded after the flash, it's got to be hardware related. It's possible the non stock rom blew out some hardware too.
Try setting brightness to manual.
A rework around may be the only viable solution.
You ever wonder what happens when one or two of the billions of semiconductor junctions/resistors/caps fails in the chipset or display? You might be looking at an example
It could be a loose connection, or a faulty ribbon cable/connector, a subassembly maybe even battery (if so there be more symptoms).
*unless a known issue in this device.
