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.

So, about 2 weeks ago, I got my HD2 off of Craigslist with a cracked screen. It worked perfectly fine with the exception of the hardly noticeable cracks. I knew I could get the replacement digitizer/screen for $40-80. I got my screen in the mail yesterday and, following the "YouTube" video tutorial found on this site, I......ugh.... replaced the screen....................I SCREWED UP BIG TIME!
First, I broke the ribbon cable for the Side "Volume Up/Down" buttons. Then, I broke the ribbon cable for the "soft keys." Ah, crap, but oh well. I figured I could use the touch screen for pretty much everything i needed to do. Well, while prying the cracked digitizer screen from the LCD, I went a bit too deep & peeled the tinted film off of the LCD. I thought nothing of it at the time. I'd already done enough damage. So the display would be a bit brighter than normal oh well.......WRONG! I put the phone back together and once I get it to power up, all I get is a white screen. I thought I missed something. So I disassemble & check 3 more times. Still a white screen.
Well, after all of this, the new digitizer/screen doesn't want to stay in place very well. So, being pissed off and curious, I pull it out and away and notice in the backside reflection of the digitizer that I can slightly make out the phone display. So, apparently the "Tinted Film" that I accidentally peeled off of the LCD makes images visible on the phone screen. I kind of damaged this film when peeling it off. Therefore, I am unable to put it back on. Does anyone know of a simple fix without replacing the LCD?
SORRY FOR THE "SHORT STORY LONG."
I was brainstorming and thought that maybe the film was polarized. So, I grabbed my sunglasses, which are polarized, and wearing them, I can faintly see the display. Anyone think maybe polarized window tint might fix my problem?
Hey man I have some electronic devices that need repair, can I send them to you to fix them?
SURE!
You can pay me in HD2 parts.
Sir i can only say 1 thing. search ebay and replace everything you damaged. only that way you will get your hd2 in perfect state.

I'd go one step further and say bin it and get a new one!
You sound just like me. That is why I never try things like that anymore. Hope it gets sorted but might be better looking for a used one.
I've got it functioning...
I found the film that I ripped off, put it over the screen and........I CAN SEE! However, the top half has lines through it. So, I must've damaged the LCD. The good news is that my phone is useable again. I just have to do everything via the touch screen and can't let the screen hibernate unless I have my charger close by. I'm just gonna keep my eye out for a cheap busted phone and eventually have a 100% phone again...
I sympathize with you. I broke HD2 while I was trying to check for loose WiFi card cable(cuz i was getting weak WiFi signals). The cable turned out to be fine but the external speaker stopped working. I opened it up again and adjusted some parts and it just got worse. the HD2 didn't power on at all. I tried fixing it but to no avail. I ended up sending the HD2 to a repair shop and was charged $170 for the repair. the repair guy said i messed up the power IC and the connector for the external speaker and he had to replace the power IC and resolder the connector.
I think I'm gonna stop trying to open up expensive phones. i was stupid thinking that since I have successfully replaced digitizer for my previous Palm T3, E2 and T5, opening up HD2 wouldn't be a problem. Should have known HD2 components are really fragile...

The best topic ever Thanks, dude!
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

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.
So it happened this morning when my alarm went off and it vibrated. I heard a plastic part vibrating also. The sharp loud noise was disgusting. I shut off my alarm thikning it was my cheap SGP case.
Later today I played around trying to find out if the silicone had a hole or something where the plastic frame was touching the SGS2 phone itself. Nope. I took the whole case off. Each time it vibrates it sounds like... ahh what the hell. I will film it for you guys now.
http://www.youtube.com/watch?v=_GoIrBmMC1U
WTF is that? I took the cover off. I took the SIM card out on another occasion too. It sounds like something on the upper left. If I push my finger down on the panel, it stops. If you notice the few seconds it is sitting on the table flat, it's fine. Just a little weight seems to calm it down. Not sure if its the vibrating motor itself because it is vibrating properly. Sounds like something is loose inside though...
Anyone experienced this before? Should I go for RMA?
Second part of the question:
Obviously being an XDA-er I'm rooted. I will flash back to stock and unroot. I bought this off of Expansys-USA so I should get *some* reasonable attempt by them to send it back. What are the chances that my warranty gets denied? I don't have a USB jig to reset the counter, but I'll of course get rid of the yellow triangle.
*grrrr... I need to dig up my Nexus S now if I have to go through warranty... I'm guessing I'll be phoneless for weeks*
I don't know if it would invalidate the warrenty or not (technically rooting/custom roms is supposed to), but when I had a problem with my stereo jack not working rather than risking it I just replaced the part myself.
The vibration motor, stereo jack and earphone speaker are all on the same part.
(I got it from this guy on ebay for about $7 if you're curious.)

I see. I'm not sure whats broken really. When I shake my SGS2 I hear something rattling inside. I'm just afraid to open the thing up... is it difficult?
Just watched your video. It sort of sounds as if somehow the vibration motor came loose from its proper spot and is now moving around vibrating against the plastic. Its normally held in with some adhesive (basically double sided tape) within a cutout area.
When I had mine apart I actually took a photo, http://i.imgur.com/fgN9F.jpg, if that makes it any more clear.
I actually recorded the process of me reinstalling the new part (excluding the disassembly, there are lots of clips of that from other people on youtube) but havent gotten around to uploading it yet since my internet connection sucks and the file is nearly 2GB.
Edit to add:
No it wasn't really all that difficult to dissassemble, it was actually pretty easy. That said I enjoy taking things apart and trying to fix them. This was the first time I've dissassembled anything as small as a cell phone, but I'm used to taking things apart and trying to fix them when they break. If you don't have any experience taking apart electronics you might want to think twice or just pay someone who fix's cell phones to do it.
If you're thinking about it, heres a video where someone shows taking it apart to get a rough idea of whats involved.
http://www.youtube.com/watch?v=QKztg1ra4-0
I decided to try and upload the video I took, once it finishes (in about 2.5 hours) it should be viewable here:

thank you for your detailed writeup. im going to try this. ive taken apart my macbook pro to install an SSD before, and a few other electronics, but i'm not the very best (i feel clumsy sometimes), but i'm willing to give this a shot.
The only thing I'm worried about is that I could potentially mess up the phone in other ways in disassembly such that my warranty won't be honored if I need to resort to that... We'll see tonight. It looks like you used two screwdrivers? Which ones will I need? I have a #000 that I see will be needed for the back plate at least...
k. opened my phone up.
i just took the screws out and the backplate. i pushd around to make sure things are tight, and they seem to be.
put it together and the vibrate thing happens VERY rarely now..
I shook my phone around and still heard something shaking (please tell me if this happens).
I opened up my phone and the camera module seems to be loose. Is it supposed to be glued down?
Just to let you know, you say you don't have a USB jig so your Flash counter may make your warranty void, but, if you flash to an ice cream sandwich ROM (Cyanogenmod 9) you can install an app called 'Triangle Away' which will basically get rid of the Flash count and yellow triangle - it needs root by the way. (search it up on XDA, it's by chainfire')
Then you can flash stock and send in for warranty.

I don't remember it being glued down. Its been a few month since I fixed mine but if I recall correctly it just fit snugly in place between some plastic fitted walls.
This is the camera module you mean right?
Edit: I also don't hear anything shaking with mine, did you mabe leave a screw loose inside?

Yeah. Camera module. That's the one. The main 8MP shooter. It's not glued down or anything. It shakes around inside. I definitely did not leave a screw inside because I only opened the back panel and I put all the screws back in.
It's weird because something making noise while shaking the phone has been documented here:
http://forum.xda-developers.com/showthread.php?t=1254520
And I noticed that when you activate camera it goes away. Quite strange but as an engineer this makes me wonder HOW that even happens? Shrug.
I'm waiting for my Samsung Focus S phone to come from the Windows Phone challenge and I'm contemplating using that for a month while my i9100 goes out for warranty. Of course I can always use my Nexus S as a backup, but part of me wants to force myself on a new platform for a month and see how that goes... Hahahaha.

Hey Random6, did you happen to find that after replacing the vibrator motor with a new one, the intensity is now less than when new? I used double sided tape, but with 1.5mm, I guess the motor won't vibrate AT ALL.
Also I found that if I don't screw the one that seems to be closest to the vibrator motor all the way in, it obviously vibrates harder, but not hard enough.
I also used two very thin copper plates to sandwich the motor between the plastic plates, but once again, that was too much and the vibrations were not transfered to the phone's body, but I could hear it doing its job.
Any suggestions?
Thanks!
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.

Hi,
my P9000 just arrived today i wanted to try it out. After the update to 20160419 i wanted to make a call but there were no sound. With my headset everything works just fine, but without there is no call possible due to no sound. Is that maybe a software-bug or is the earpiece speaker broken?
I hope i don't have to send it back

Factory reset, if it doesn't help flash stock ROM again and report
Both did not help unfortunately. Any other advice than sending it in? I heard tomrepair.de here in germany is not quite good (8-10 weeks repair time and no change in the problem). Are there any other repair Centers? Can i do it by my own? Whrer can I buy spare parts?

Well, then it's maybe a loose/cold connection. I would open the phone by myself and take a look at it, but i don't want to loose warranty

It is soldered to board with wire. Broken my today when trying to removing it Hope they release soon replacement parts like earpiece, camera, screen etc.
http://i.imgur.com/JjF9qGI.jpg
It is definitely software related.
In the end I send the phone back to the reseller and got my money back. Because it is nearly impossible to send a smartphone from Germany to China, i was allowed to remove the battery for the shipping. Now I'm a happy Honor 5x user.
I think the battery is still working (unless i damaged it by removing it, it is really good glued), so if anyone is in need for it, i could sell it.
For anyone that might be still interested and ends up here... I just repaired the (previously broken) earpiece of my Elephone P9000. It is not too difficult to do yourself, but you definitely need patience, precision, a steady hand, good eyes and some tools. Here is wat I did. By the way, I first tried a factory reset, which did not help me. But you never know...
I ordered a replacement earpiece via AliExpress. This cost me less than €8, and the part arrived within 12 days. Not bad.
I watched a P9000 repair video on YouTube to prevent making big mistakes/damage by opening the phone. I my case, the flatcable to the power and volume buttons was glued to the back of the phone, so I used this part as a hinge to open the back like a door.
I unscrewed the plastic cover that covers the motherboard (5 screws). It still has a couple of hooks, but with some prying it will come loose. Caution as the flatcable to the fingerprint sensor is attached to the board, so use this (again) as a hinge and flip the cover over from top to bottom.
There is flatcable that partially covers the earpice (at the top middle, soldere with two mini-leads, black & red). I could easily fold this a bit back. Wit a small screwdriver, I pried out the earpiece. Then with a fine soldering iron, I unsoldered the two leads. Remember where the red lead should be attached (bottom for me).
Solder in the new earpiece and put everything back together again.
Drop me a line if you have questions, I'll gladly help to fix your Elephone earpiece if it's broken.
