HTC Titan proximity sensor not working - HTC Titan

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

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.

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.

[Q] NEWBIE HERE! Really F'd my HD2 up!!! HELP!!!

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...

How to remove "moisture under screen"

Hi all,
I had a big spot (3'') at the middle of my tab. It seems it is related to case warping and NOT related to temperature, etc. What I am describing worked for me and my tab now has a perfect screen (this is the 7th day).
I solved it by doing the following:
1) put the tab on a flat table. The screen should face upwards.
2) with two fingers push down at the top left and top right corner at the same time. You should try to "bend" the top corners towards the table. This will pull the screen away from the digitiser.
While you do this you should see the spot shrinking. If it does put some more pressure until it completely disappears. Don't put too much pressure to break anything
If, while you push, the spot doesn't shrink then stop and try the bottom left/right, perhaps your tab is bent there...
Hope it helps.
DISC:
I am describing here what worked for me... it might not work for everyone... don't blame me if it doesn't work or if it makes the situation worse.
Putting in the fridge less than 10 minutes works for me
Sending mine back to Samsung to have the LCD replaced worked for me. It's obviously a flaw in the design and the rush to get it to market without thoroughly testing it is the root of the problem.
Why on earth would you try to fix something like this yourself? You won't fix it, and its likely you will make it worse (battery damage etc)
This is why manufacturer gives you warranty, with gtab you have 2 yrs of it... I just send it few weeks without won't kill you but at least you will have fully functional device...
Sent from my GT-P7510 using xda premium
Mmmm Sure this helps?
I'm kinda scratching my head over all these fridge repairs for the Newton's rings problems. There shouldn't be a single 10.1 Tab anywhere on the planet that isn't in warranty. Just get it repaired/replaced.
None of the published fixes worked for mine anyway. Tried refrigerator, freezer, blowing, pushing, twisting, etc.
Verizon is replacing it. Just get it fixed right.
My biggest concern is the couple of reports of folks getting it back from Samsung and having the exact same problem reappear after 2 months. I am not sure anyone has conclusively confirmed an "improved" screen being installed during warranty service.
Could indicate the hardware is just fatally flawed for being subjected to heat >80F and any kind of pressure on the screen.
Keeping my fingers crossed that I get mine back with some sort of new and improved screen.
Works Like Charm
Tried this myself and it worked perfect!!! Thanks so much!!!

[Q] [Help] Strange dark spot on S2 camera

Hey everyone,
I noticed a small dark spot on the left of the pictures I was taking with the phone, and ignored it. This was about 2 months ago.
But just today, I turned on the camera and saw a large smiley face dark patch on the camera. iv tried cleaning it with compressed air, rubbing alcohol, restarting the phone, reflashing the stock firmware. Nothing is helping.
Im really really annoyed, for a phone so expensive why is it plagued with so many problems? Nothing is stopping me from tossing this thing and getting an HTC or something because I am getting a bit fed up with the pink spot, usb port problems, grey spot etc etc. Anyway, enough complaining.
For now, any suggestions?
http://i.imgflash.com/plb.jpg
I'll give you $20 for the phone.
Didn't realise this was a sale thread...
It's not. When people throw tantys along the lines of 'I'm going to throw this phone against the wall & get a <insert brand/model of phone here>', most people on here roll their eyes and/or laugh. And tend to ignore the person posting same.
Now...To your issue.
It may well be a physical issue with the camera/lens. There may be something trapped inside the glass covering the lens (maybe at manufacture), or it could be a scratch/blemish of some sort on the glass itself.
If it's that much of an issue, I'd send it in for warranty service. Obviously if it's an issue around a scratch or blemish on the glass covering the lens that has developed after you bought the phone, you might well have problems getting it fixed under warranty.
The other thing you could try (you didn't give us any info about rom) would be to go back to stock if you're currently not running stock to rule out a firmware issue, though you did say you noticed it two months ago & let it slide.
To me, that sounds like it's either a hardware problem with the camera/sensor or that lens/glass issue I mentioned.
I too got a spot on the top right hand corner if I use the camera, not otherwise. It's very annoying and now my s2 is NOT in warranty period. What should I do? The upper glass on camera is clean without any scratches.

[Q] S-pen not working at all after bezel replacement

Hey guys, first time poster but long time reader here. I'm having a problem with my galaxy note 2, my s-pen is not working at all, and using a different spen does not solve the problem. Here's what I did, I had to replace the bezel because i dropped it and it was badly damaged, and prior to that it was working just fine. I took the battery, sd card, sim card and the spen out and then removed and replaced the bezel as carefully as possible, I then replaced all of them and turned on the phone as normal. I did not tamper with the screen itself in any way.
Well, immediately after turning the phone on, I noticed the spen is not working at all. The only response I get from it is when I take it out of the holster and the phone makes a noise and vibrates. I am on a custom rom (alliance), and have switched to another rom just to make sure that it isn't the rom's fault.
I have no idea what to do now, I'm really hoping you guys can help me out. It is still under warranty, so should I just return it to stock and take it to verizon? For anyone with experience, if I do end up taking it to verizon, will they swap out the phone with a new one on the spot or will they send me one of their "pre-owned" devices instead? Thanks for the help.
I took the bezel off to see if anything looked out of the ordinary, and I actually found the problem! In my own stupidity, I let a connector come loose when I was swapping bezels. If you're looking at it from the back of the phone, it is in the top left corner, next to the camera, it's a gold rectangular connector, apparently it goes to the wacom digitizer. I'll see if I can find a picture of it later to post.
So bottom line, if you are having to replace the bezel like I did, make sure to check your connections before putting the screws in, because that connector is easy to knock loose.
Thanks anyway guys, I'm very sorry for wasting your time, but I hope this will help someone else in the same position.
the same problem
i have the same problem. i has replaced the screen and the s-pen do not work any more. can you post a picture showing this connector? because the screen spare part that i buy has only one connector. thanks.

Phone Difficult To Wake Up

Sometimes if my G5 has not been used for an hour or so, it is refusing to wake up from double tap, power button or volume button quick shortcut. Only plugging it in has seemed to wake it up on these occasions.
Has anyone else had this issue?
Not yet.
I am chocking this up to poor software implementation using the ambient sensor. I found similar issues that the OP was describing, and in my testing, was able to verify something is wonky with how the phone "thinks" it is being looked at or not.
Simply put, if you cover the ambient sensor and the camera (on my device) with your finger, while the phone is asleep/screen off, no matter how many times you press the power button on the back/fingerprint scan, the screen will fail to come up. The moment I introduce some light into the room (open up the sensor), I am able to get response back on the phone.
Ran into this issue last night and for the life of me couldn't figure it out until daylight hit . Also, my case might be obstructing the sensor (lifeproof fre), but I also noticed the issue with no case on.
Logically, I imagine LG was trying to limit power consumption with accidental presses, etc. If the phone knows it is in a dark place, it won't respond (because it thinks it is in a pocket or a bag of some sort). My rebuttle for this is how do they anticipate planning for night-time use of the phone, or are we limited to a daywalker only device?
I am heading down to an AT&T store and seeing if I can replicate this on demo units as well. In which case, we know the issue is inherent in the device (and hopefully addressed in a software update). If I am not able to replicate this at the store, then I bet OP and I got bad units.
Thanks for looking. If anyone has any feedback, or can repro or not repro this issue, please chime back .

I have also experienced this issue (opened a thread a week ago). I have the exact same lifeproof case and my problem occured at night as well. Phone did not want to wake up at all until I either restarted it or had some light in the room.
Same problem, same case.
What I have found is if you pull the phone out of the case it wakes up. Thinking proximity sensor.
Sent from my LG-H830 using XDA-Developers mobile app
Yup. It really doesn't take much extra coding for them to allow the power button to "Always Wake" the device... I imagine there will be an update in the near future.
As for me... jumping ship to the S7 edge. I really liked the G3, and was hoping this phone could have been that for me... Well, not like I really swap batteries out often anyway
Same case. Same issue. Take the phone out of the case and throw a blanket over yourself and the phone. (Simulating night) and my screen unlocks easy peasy. Something about this lifeproof case. You would think this issue would have been caught in testing and QC.
Yes the phone has a built prox. override. But it only becomes an issue at night. Outside of the case I have no issues with prox. sensor.
I have experuenced this exact same issue with my g5. Whenever its in the dark the power button nor the double tap will wake the screen when in the lifeproof fre case. When out of the case the phone works just fine.
Word to the wise though if you have a zagg glass screen protector and drop your phone both the screen protector and the screen with shatter even if in the lifeproof case. I just experienced this and now have a replacement phone. Just a heads up.

I have the rs988 variant and I have noticed this behavior when screen is in always on mode: if I suddenly change from light to dark by covering sensors, the always on clock goes out and nothing I do will allow it to wake up, until I allow brighter light again and the clock reappears. and I can use the double tap and power button again to see the screen. I also notice that the always on clock seems to have an auto brightness independent of the screen settings - I leave screen at 50% no auto brightness, yet I still see clock light levels dim in low light, One other thing - I notice that when I answer a call the screen blanks out (the way it is supposed to ) but does not reappear until I press the power button, just taking away from my ear does not bring display back; I also have the lifeproof case. and just removed it and verified my display now works when I take away from my ear; I just took some spray lens cleaner and cleaned all the surfaces of the phone and case with a microfiber cloth and put it back together and has vastly improved the issue, maybe gone, not sure yet. Update: seems like no matter how clean it is there is still a problem with the case doing something to the proximity detector, cleaning made it better. I can always wake up with the power button for the calling screen(sometimes swiping across top sensor too), wonder if the sensor is a passive light sensor or active (rf/infrared emission)
Same issue here same life proof case however it's getting worse as I am a mechanic and this phone goes through greasy hell. The plastic lenses on the lifeproof case are getting scratched and it's getting worse. It is also having a hard time autofocusing through this case. When you pull it out the phone is gorgeous and looks brand new. Good case but it has some downsides. Still better than a broken phone.

There are allot of other cases you can use but not waterproof. That really sucks good thing for this thread I was going to buy a lifeproof case. Using a otterbox defender right now. Thanks for the post guys saved me some grief.
still under warranty?

if still under warranty, see if they will honor it. They did with mine but that was right at the beginning when these problems were linked to the case; mine was in the first 3 months, but the new one worked well for a while, now a little flakey again but not enough to bother me...too bad, a great case otherwise

It's not a bug and not poor implementation. Its not light for "dark rooms" lol.. As far as I know it's the proximity sensor. When it is blocked it means the phone is in a pocket or bag and should not register taps. It really makes sense. If you dont xover the sensor and double tap doesn't work ..well.. Well, eother you have defective device or sensor , or the sensor is blocked (maybe bad screen protector?). This didnt happen with my G5 even once. It works 100% (assuming I tapped the same place)
Are the problems as described in this thread still manifesting on current firmware?
