Hello there everyone, im a newbie here and i joined for this specific question. I bought a replacement digitizer for my aria and replaced it myself and the screen works fine. The first time i turned it on i did a test call and i couldnt hear anything through the earpiece. i took it apart and flipped the earpiece around. did another test call and yes i could hear the call fine, but the screen just stayed black. I see that many people have this problem after a new screen, and i was wondering how to fix it. im unaware of what the proximity sensor is really, im not sure what it looks like so i am unable to do the black tape trick to take away any sunlight it is receiving. if someone could explain what it looks like and how to fix this thatd be amazing. oh and i have already tried the app Sanity, its cool but didnt work. thanks!
Here's a picture showing where window for the proximity sensor is: http://i.imgur.com/ayQhv.jpg . It's almost impossible to see unless you are standing in direct sunlight or another extremely bright light. Based on that you should be able to find the proximity sensor itself which would sit directly below that window in the phone.
If you don't want to open the phone up again, you can also consider disabling the sensor. You can read about it in the two posts I link to here: http://forum.xda-developers.com/showpost.php?p=26515001&postcount=25 . I know this works in CM7 but I have no idea whether it works with newer ROMs.

When you replaced the digitizer you most likely forgot to move the black gasket from the old part to the new one.
There is a piece of black tape and a rubber gasket that surrounds the prox sensor. If you don't move these 2 pieces over the problem will continue.

There are two possible options
1) play with screen delay using init.rc file, it fixes some black screen issues
2) for me sometimes pushing screen harder than usual makes it go bright again

Had this phone about 3 weeks now and all of a sudden whenever I make a phone call the screen just goes black until I take the battery out or the other person hangs up. Is there a way to tweak the proximity sensor settings like on the omnia 7 etc?
I'm having the exact same issue. I've only had my Titan for about four days now.
I just firmly pressed on the front and back of the device as if to correctly place put the back case on. This works for a while and 'randomly' quits. I have yet to figure this one out.
I've not had this problem but you could try the other rom from here. I had the .02 but changed it to .06

Not had any problems with my titan since I flashed it.

Thanks! I'm gonna' try flashing this. HOPEFULLY, it will work.
I'll post back with my result.
Nothing! Tried the ROM update but no luck. Still having the same problem.
Dam thats a shame, could be a hardware issue
same issue on mine. Had it 2 weeks and it just started going black when calls come in or go out. I have a replacement on the way, I hope its an isolated issue...
Same here. Had mine for 2 months and now I have this issue.
Any ideas on how to solve this yet?
same here...
any hints if its a hardware issue or a software issue
mine also worked a wile and then stopped working...
You may already have tried or been aware of this so forgive my two penneth worth, When I had my HD2 It was the screen protector that tripped out the light sensor and kept the screen dark etc, May be worth a try if you have one fitted as it did the trick.
HTC Titan Prox Sensor
I do hardware repairs on phones, and currently having this issue with an HTC Titan. It seems very likely to be a hardware issue. The back cover feels loose and sloppy in my opinion, yet seems to play a role in properly grounding some of the auxiliary sensors. I'm considering trying to order the part, but it seems to be impossible to find except from a used phone. The proximity sensor is on a small chipboard that snaps directly into a connector on the motherboard. The solution of pressing the screen and back housing together makes sense if that proximity sensor isn't making a good connection to the board (or if it isn't grounding properly).
In my experience, I'd say this phone is a pain in the butt to diagnose and repair.
Exact same problem! Was thinking about doing a hard reset, but it seems like that won't fix it. I bought my Titan used, and maybe that's why it was on eBay. Phone works perfectly otherwise, absolutely love it. They sell new covers on Amazon, maybe that will fix it, by applying more pressure on the proximity sensor. Wish there was a simple fix.
I have this issue as well. I have found out that when you press the upper right corner of the screen the display comes back on but as soon as you let go it goes black again.
Also if you slightly open the back cover from the bottom the display comes back on as well but you lose signal because the antenna is disconnected. When you close the back cover the display goes black again.
It happens with outgoing and incoming calls.
This is really annoying and if I would very much like to know if it's a hardware or software issue.
---------- Post added at 05:38 PM ---------- Previous post was at 05:20 PM ----------
Update:
I think I've found a solution.
I believe the the proximity sensor is in the narrow gap above the screen.
I opened the back cover and I slightly scratched the two contacts on the top of the back cover with my fingernail.
My Titan somehow is now working again and when I move my finger close to the narrow gap the display goes black.
I therefore think it's just a matter of a dodgy contact between the proximity sensor and the back cover.
I think I'll order a new back cover fom eBay to see if this improves things. My back cover is damaged anyway.
Possible Solution
i hope this is the solution cuz im tired of messing with this phone (we lost money trying to repair this phone, ie. negative profit, cuz the lcd and digitizer are fused together and it took forever for the parts to be available online). BIG Thanks to everyone who contributed to this forum thread.
The problem is almost certainly hardware and related to the back cover. good news means that it should cost nothing to fix. *warning* as always, you could break your phone if you arent careful. I havent tested this solution but i will tomorrow. On the motherboard are "metal brushes". That means springy metal contacts that are meant to make contacts between parts that arent closely touching. look at the back cover and find those contact plates, then look on the board for the corresponding brushes. gently pull those brushes up away from the motherboard to make them extend further, and see if you can get the back cover to fit more snugly on the phone. be careful with those brushes, metal can only be bent so far before breaking and then youll have to do board-level soldering (pain in the butt, not easy). if you can ensure proper contact between the back cover and the motherboard, then you shouldnt have any more issues with the proximity sensor.
this is my educated guess, let me know if you have any luck.
PS! been using iphone 4 for like a month, and the more i use it the more i hate it. i typed this up with iphone 4. so much hardware power with so little control. id recommend iphone to anyone who doesnt like technology. iOS is a POS
Called HTC and I'm still under warranty. I'm going to be sending in the phone for repairs tomorrow for this problem, we'll see what happens. They said it'd take 14 days to get my phone back.

Hi Flavio, have you bought a new cover? Has it fixed your problem?
Have the same problem with the sensor, i´ve tried other roms to, but still the same problem. i dont think, that this problem is a hardware issue of the proximity sensor, becaue sometimes it works sometimes note... very curious...
I just got a new Titan with the same problem. I took the phone to HTC repair center and the repair status on their website shows is that its been fixed, meaning I should get it back early next week. I will report here about the description what they did to it.
And this is clearly a HW issue. Taking off the back cover seems to affect little, but not 100% remove the problem.
Had this issue. When I sent it off to HTC they replaced the screen together with the dusty FFC issue
I had a similar problem that was fixed by turning of "Automatically adjust" in the brightness setting.
I just got my lumia 920 in black last night and i love the phone no complaints...today just around 30 min ago i noticed while taking it out and putting the phone in my pocket and putting it up to my ear to talk it feels like something is loose inside. Like if you shake the phone something is moving around in the phone and it feels heavy. Nothing is wrong with the phone otherwise everything works. Called att they said they will swap but has anyone else had this issue?
Ok so i just read another thread about the lumia 920 rattles. Mine rattles if i shake it without any vibration going on. Should I take it back to att or is the phone fine and meant to be like this?
Your probably hearing/referring to the floating sensor. Mine does the same thing, but I can JUST barely hear the rattle shaking it. If you hear a lot of movement shaking the phone I would take it back.

You dont really hear it. Its just when i shake the phone theirs a little play almost like a little vibration but not exactly.
It's the "floating" sensor.
*Oops wrong thread. My apologies.
So my phone is ok then? It is suppose to shake a little inside when i shake the phone? feels like a metal plate is moving around slightly in my phone.
Go to any phone dealership that has it in stock, and ask if they have any idea if its supposed to be like that or not. If they have a model there for display, just check if its similiar or not.
Id do that as a first step before sending the phone away for X weeks in order to get a replacement.
edit: Unless of course you can go right to the store you got it from and get a replacement right then and there, then Id just go do that.
It's the floating camera lens. It's perfectly normal.
Mine rattles also.
Ok i went to att and they swapped it right out...they had 2 of the phones as models and it did not rattle when you shook it. Also one of the workers had it as well and shook his and said he didnt feel anything. The guy said this is the first time he seen someone come in and do an exchange for this reason. But he as well shook my device and said its not suppose to be like that.
Nice to see it worked itself out .

Well then there's a lot of phones out there thats 'defective' because I hear a slight shaking inside my phone. Once again. Perfectly normal due to the floating sensor.
Got my phone yesterday in the mail and it does the same thing. Everything seems to be working fine though.

I've tried it on the test units at the AT&T store and one of my friends has the white version and it all has the slight rattling.
If you're recording a video and you take the phone violently, you can hear it through the replay.
So I dropped my phone and the screen cracked. No biggie as I am fairly handy. Bought a new digitizer and replaced it. All the functions work... that is until I try and make a phone call. No voice registers. Try and use the voice command option and it doesn't hear anything. Ok, so I need a $5 mic from ebay. I think it goes deeper than this. When I make the phone call the screen automatically goes black and I can't get it to come back up until the call ends. I made a phone call and swear I can hear a faint echo of my voice in the earpiece. I've had it apart half a dozen times or more checking everything. It all looks good. I think the phone is only like 2 months old so I'm not even sure if there's a warranty on it, especially now that I've replaced the screen. Any help on this is greatly appreciated. Thanks for reading.

Hello, I am having the exact same problem on my friends Radar. Did you ever figure it out? where did you buy the digitizer, Ebay? Thanks!

For the Radar, it is very easy to damage the mic flex if you don't remove it prior to removing the outer housing of the phone, and also if you don't install it after installing the housing again. There is very little clearance when levering the housing off of the board/lcd, so if the flex is not removed, it can crease, causing the internal wires of the flex to be damaged.
Regarding the screen going black, this is usually caused by a fault or blocked proximity sensor, or sometimes a missing grommet that goes around the sensor to block extraneous light from interfering with the sensor. I suggest double checking to make sure that nothing is blocking the sensor, that the sensor is not damaged or unplugged in any way, and that any grommet that was originally there is still there.
I have a Radar open in front of me right now and it is supposed to have a grommet around the proximity sensor, so if you happened to have lost it or threw it away with the old digitizer, you might be out of luck. Try to find some way to separate the transmitting and recieving components of the sensor so that they can't interfere with eachother (so that the light emitted by the transmitter doesn't immediately reflect off of the digitizer and back into the reciever).
Kind of hard to explain, sorry.
I've searched for the answer to this and can't find it. Sorry if I missed it and this is a double post but I have to get this working. So when I make a call on the amaze the phone screen wont come on. I think it's because the front-facing camera is a bit blurry after a fun adventure where I accidentally threw it in the trash. Anyway, is there a way to just make the screen not shut off while talking? I'd buy a replacement for the camera (it's pretty cheap, maybe 12 bucks shipped), but I seriously don't want to take this thing apart ever again.
Any tips appreciated! Phone is running stock rom, but if needed I can root/flash anything anyone suggests.

the screen shuts off because the proximity sensor is covered. Its not the camera. See if you can find a way to disable it from an app or something, but that's what is wrong...not the camera...

Thanks for the tip, I thought it was the camera. I took the phone apart and took a look at the proximity sensor, I dont know what was wrong with it but i scraped some goop off the front of it with a sharp knife and now it's working
Hey everyone. Just got the z5c and I noticed that the phone"s vibration is a bit "loose" comooring to my z3c. Also, about every 1 out of 4 vibrations makes a very slight but audible crackling sound. Has anyone else experienced this? Is that considered normal? It doesn't bother me too much but my main concern is the phone's longevity. Thanks
I have not noticed that on mine.
Mine too (Z5 E6653)
I'm not worried about it. The phone is NEW (2 months might be considered new).
And if it would break, the phone has 2 years warranty. And if it's outta warranty, it's not so hard to replace some parts yourself.

I've read that in another thread. It has something to do with the camera construction. If you you flick at the back next to the camera, you can hear the ratteling, too. In my case, after opening the camera app, it's gone when you flick against the same spot...
If that's not the case... well I'd return...

What does "snip at the back" mean? I'm not familiar with "snip" in that context.
I Do also hear this noise produced by the Vibration engine. I am using a tempered glass screen protector and I am wondering if the Sound might Come from the protector.
Did you experience any issues with this so far except for the "annoying" Sound?
i dont get that sound (film)
i saw another thread on this topic, i guess is the glass i have 5.1.1 maybe it also matter os ver
No such problem on mine. Tested with vibration diagnostics, nothing comes up.

When I Do the Vibration test, I am also Not able to hear that Sound. It only comes up when the Phone vibrates only shortly, for example when you touch the home Button or when you write a text with Vibration Feedback.
Recently I recognized that I can reproduce that rattling Sound by tapping on the backside next to the camera. So I assume the Sound is produced by the camera lense because I read somewhere that the lense somehow "floats" freely on the Sensor.
