Hi All,
I have updated to the latest AKU3 ROMs and also a few months ago I replaced the housing...However, I've noticed that the screen does not automatically rotate when the screen is swivelled??
Now is this because I did something during re-assembly of the housing OR is there something in the ROM's that disables the hardware somehow??
Cheers
ODY
Unlikely to be the rom, since it's part of the system HTC provided.
If it's been disassembled it's more likely that.

hey VJ, sorry to bother but do you know what jumper/cable/connector/switch to jump/disconnect/tape inside the Universal to keep it from switching?
I'm sure I saw someone mention that the screen rotation is done by a magnet and switch? It's possible that maybe a small magnet fell out during disassembly? But I have looked throught the Universal repair manual and I can't find any reference to such a magnet??
I'd be nice to know exactly where it is so one would be able to take it out, if it were easy. I don't know if I wanna disasemble mine yet...
EDIT found it!! If you use a very, very light metal chain, as I did, with a keyring @ end, you can hover it around the Universal and see the tension of the chain when it's near the magnet. the keyring sticks too!
it's on the lid, behind the video-call video camera. I'm going to check the lid part of the manual.
Well taking the screen section apart is easy! You don't have to disassemble the whole unit. Looks like my magnet fell out then! Trouble is I want to sell mine so I'll just have to declare the auto screen rotate doesn't work (I've made sure that there is the rotate screen icon on the task bar though!!)

it works!! I tested it with the very small and highly magnetic point in the bezel of my tablet PC (to hold the pen) and it did change orientation.
thing is that it seems to be stuck beside the sound-holes (when the unit is closed).
I wonder how could I disassemble the lid only? are none of those screws @ the bottom connected to the back part of the lid? if so, that would be awesome!
Hi, on the xda's ftp, you'll find the maintenance manual for Universal...may help you to disassemble yours
thanx for the link!
however, it seems rather risky to try to pry the bezel open while still on the unit. Anyways I'm doing it right know. I'll get back to you.
I did pry it out and took the magnet off... painless(*) procedure and flea-sized magnet! don't loose!
I took a couple of pictures detailing the magnet position and the lid disassembled while still on the unit.
if you want to do this procedure do not loose the tiny screws and...
(*) be careful with the outer speaker (the one that lets you hear a call while the screen is facing the keyboard when closed), it isn't hard wired, it's just two small and fine contacts that might get distorted when putting the lid cover back... I had to take mine out again to correct this problem.
also, be careful with the screw driver and digitizer, as you'll be working in very akward positions to avoid disassembling the whole unit, and take off the battery of course.
Thanks for the photos - looks like my magnet feel out so I bought some 1/8 inch square magnets from ebay. It took a couple to find the sweet spot where the screen rotated but at least it works fibe now!

no problem. I'm also going to put the magnet back, now the unit doesn't now when it's closed, and therefore the outer speaker does not work. the screen also does not turn off when closed, only when the system timer tells it too... oh well.
you can turn the screen off by pressing the power button briefly.
no ext speaker though! maybe there's a way in software to disable just the rotation; i think the guys trying to get linux comfortable on the universal have some experience with it, maybe they can help.
Really need help here,
My hermes suddenly decided that visuals are no longer needed.
That means the screens stays off all the time (yes even in bootloader mode).
It works, receive calls and flashes roms but in no situation can I see anything on the screen (pitch black screen).
I've got no warranty so I took it apart and checked each cable and connector - no issues were seen. I tried changing SPL-s, RUU, Roms all worked but left my tytn with that black screen.
Did anyone see this happen or has any advice?
This sucks big time :-(
No one? Oh man, I guess it's dead then :-(
Last bump before giving up and throwing it away - please?
send it to me if your gonna throw it away : - 0
I've given up on mine as well. It has white screen though. Where do I dump this thing?
If it is out of warrenty, I would take it apart as is sounds like the hardware, check the connections to the LCD. Does the backlight still work, or if you put it in strong sunlight, can you see the LCD working?
My Hermes had a white screen also. I found that if I squeeze the bottom right hand corner whilst resetting it would sometimes work. It seems there is a chip on the switch board that needs the right ammount of pressure on it. I think it was a design flaw as the herm200 and 300 are different. If applying pressure works and you are confident enough take the hermes apart and put a couple of small pieces of plastic or paper between the front buttons and the small square chip on the switch board. This worked for me.
The service guide is available if you google. Let me know if you need more info.
As for the black screen that sounds more serious sorry not seen that one.
what are you guys willing to sell your pdas for? Mine fell in a puddle and i need one for parts. The white screen might be fixable the first couple of times but then it dies off for good, the black screen i've never heard of.
So if you want to sell for a reasonably cheap price let me know, i can buy a new keypad online for $50. So around there would be nice!

I just tested this on mine and actually got some results.
mines the opposite though, it will NOT work with any pressure. I left all the screws loose for that board under the buttons, and left the LCD assemble screws out on that end and it works, But if I press the keys it whites out again and won't come back until I repeat the dis-assemble/re-assemble
I had a similar problem but this was after someone dropped mine on the floor. The screen would just be white screen, while everything worked. If I pressed the bottom right of the phone it would sometimes come on and stay on for a little while but would eventually always go to white screen.
I did manage to use the phone but had use a program called Net Control which allowed me to control the phone over WIFI with the phone screen shown on the PC. Got the phone replaced in the end by the people who dropped it.
i got the flex cable and my phone still has the white screen problem....wtf///
So i recently upgraded to Lollipop but my proximity sensor is broken. I used an app called Proximity Screen off lite but it is not working on latest android lollipop. So now when i make a call my screen goes dark until the call is disconnected from other party. same is the case with incoming call. Please help
I was in the same situation as you last weekend. Unfortunately, there's no way to get around it in software that I know of. I even went as far as developing an app from scratch to duplicate Proximity Screen Off Lite's functionality, but ended up hitting a road block on the OS level. Another option that would've worked pre-5.0 was to use an xposed mod to disable the proximity sensor, but of course that doesn't work in 5.0 now. Hopefully someone else can chime in with a software solution that I couldn't figure out.
Did you replace your phone's screen by any chance?

I replaced the original screen with an after-market one as well, and that's what caused my proximity sensor issue. There is a good chance your proximity sensor is actually working perfectly, but the after-market screen is blocking it from reading a "far" value. If you're comfortable with taking your phone apart, you could fix it without replacing anything. There were two things that I did to fix mine, but I'm not sure which of the two actually did the trick. 1) I repositioned the sensor so that it sits further away from the glass, and 2) I scratched off the black paint on the back side of the glass around the two clear sensor holes. Obviously you should attempt option 1 first, because the second option is permanent and will damage the aesthetics of your phone. Others have reported success with option 1, by gluing a thin spacer with two holes to the front of the sensor, but I did not have any luck with it when I tried initially. You will find that it helps a lot to do this while the phone is on, and you can see the results of your changes immediately with the Proximity Sensor Finder app.
Edit: Before you attempt any of the fixes, you should verify that your sensor is in fact working by pointing it away from the phone after opening up the back.
I had the same problem, I gave up on a software fix and I ended up taking the phone apart and fixing it outright. It's not too difficult, all you need is a plastic tool to open the case and a T5 and a 00 screwdriver.
There's a good youtube video (I can't link - see /watch?v=AZDAIgwbXk4) showing how to do it. Skip the battery section, you can keep that in place. At 9:00 he indicates where the proximity sensor and light sensor are. Take the small rubber gasket that covers the two sensors, and flip it around so that the larger hole is over the proximity sensor. Put it back together and turn it on, it should work perfectly.
Also, in the interim, you may wish to have your phone end calls with the power button, it can be found under accessibility settings. At least that way you won't be stuck waiting for the other party to pick up or hang up.

I had the same problem, solved by a thin plastic sheat that I drilled two holes in and then cut to the right size.
I placed the plastic part in the bottom of the hole, where to fit the sensor. I also shaved of aboute 1 mm on the part that presses the sensor from the back.
( I hade already taken the blackish film away in a own attempt to fix the problem, at least the light sensor seems to meassure more accurat)
Hi all, I've similar problem on my LG G2 D802. I have tempered glass with covered prox. On KK everything was OK, but unfortunately Lollipop has much more intensivity on prox
and I had the same issue as you, I mean - turned screen while I maked call and vice versa. Moreover, I can't get in to the service menu on LP (AOSP 5.1.1).
I bought new tempered glass with uncovered prox but fortunately Xposed has working old module: Disable proximity sensor.
I don't know about what module you guys talked about but this module works very well.
Hi,
I've recently changed the LCD panel on my Nexus 4, as well as the headphone jack (which includes the proximity sensor) - the screen was broken, and the headphone jack had very noisy output.
After putting it back together, I noticed that the proximity sensor wasn't working - during calls, it would constantly blank out the screen, and there was no way to unblank it (i.e. it seems to permanently think there's something there).
I took it apart again and noticed that the rubber gasket that fits behind the sensor is missing - it must have come off during the repair and gotten lost.
I tried putting some Blu-Tack behind it as a temporary fix, but no change. Now, I'm not so sure the new proximity sensor is working either.
Anyhow, my first question is, where can I buy a replacement rubber gasket? I've done a search online, and I can't seem to find it for sale anywhere?
Is it available as part of another spare part for the Nexus 4?
Cheers,
Victor
I had to replace the screen on my n4 too and fixing the proximity sensor was a pain in the ass. I had the rubber gasket but it was only working when the front panel was not attached as soon as i attached the front panel it stops working i.e. when in call the screen goes off but it doesn't come back on. So what the guy did was to scratch off the two holes on the top left from the inside of the panel. its looks a bit nasty but its working fine now. you might wana try to scratch off a bit neatly. like in a round shape.
I dont know if the gasket is the cause, but I know a case where this exact problem happens : its when u don't push the sensor well enough to fit in its place, cuz it should be near enough, or it'd blank the screen during calls. Try using a flat screw driver, and push the orange part where the sensors are well enough, that should do the work ( don't push haaard or I'll Damage it). I hope that'd help, cuz finding this gasket is hard. And this applies also for the guy who commented, cuz this is the case for him

According to this post:

Hey guys,
just yesterday I got my phone back from repair (I cracked my screen, nothing was working then).
Here is a photo of my old screen, which had a hole right below the upper loud speaker:
I think it might be that the drop broke the sensor, and not the repair itself?!?
Using an app like this: https://play.google.com/store/apps/details?id=com.tigermonster.proxfinder shows that my sensor is constantly detecting something.
I'm not using any screen protectors or anything
For now I rooted my device and disabled the sensor by installing the xposed framework and then using http://repo.xposed.info/module/com.mrchandler.disableprox
Strangely enough, yesterday, like 3h after I got my phone back I called someone and everything, including the sensor was working perfectly!
Can anyone show me a picture of such a proximity sensor? Do you guys think a fix like in this video shown: https://www.youtube.com/watch?v=HPHsianYnqo, putting a piece of paper behind the proximity sensor could work?
You never ended up showing any images of the phone before/after the repair but if you have a screen protector fitted to the screen and it doesn't have a little cutout on the right just below the top speaker then the protector is constantly tripping the proximity sensor.
Thanks for your answer. Like I said, I am not using any screen protectors.
Here's an image of my old screen:
http://imgur.com/ufNSseD
I don't think it has anything to do with that damage now tbh, because it was working well yesterday. I guess maybe the connector loosened itself?
Which one here in the pictures to step 6 is the proximity sensor? https://de.ifixit.com/Teardown/Nexus+6P+Teardown/51660

Thanks for the info about the position of the sensor - I'll definitely do that when I'm going to disassemble my phone (which is gonna take a while since I'm waiting to receive a new rear housing from a seller in the US).
I'm planning to disassemble as little as possible, so I'm hoping it's easy to access the proximity sensor (but guessing by the pictures it should be).

Good luck. Hope you can fix it by cleaning it. Make sure to have some thermal compound on hand to replace the old stuff when you disassemble.
Hey one more quick question:
Do you think it's possible to remove the motherboard without removing the battery?
I guess that the problem is that the proximity sensor is either too close to the screen, or too far away (like there's some small gap between the proximity sensor and the screen). I will probably have to remove the motherboard if it's the former (if it's the latter I can just put something like a pice of paper at the back of the rubber).

You won't need to remove the battery to remove the main board. You'll just have to unplug it.
Alright, thanks. I am wondering about another thing: Why are there two holes for the light and proximity sensor on the backside of the phone? I was planning to try and first stick some piece of paper on top of that rubber plastic to get the sensor closer to the screen. Why the holes?

I don't know which type of proximity sensor this is, IR, led, electromagnetic etc. But all proximity sensors I know of have two "eyes" One eye emits ir, led, or electromagnetic field, the other eye looks for a change in the return field. I think you'll find a scratched, smashed return eye. Or debris lodged in the sensor housing. Use a magnifying glass and excellent lighting.
If you shine a bright flashlight at the sensor through the screen can you see anything blocking the eyes? Doesn't matter I guess, you'd have to disassemble to get it out of the way anyways.

It looks like the prox sensor comes covered in a rubber cover. In this pic the rubber is there:

In this pic they removed the rubber to expose the prox sensor:
https://d3nevzfk7ii3be.cloudfront.net/igi/eDldW3bJmHSbQEYF.huge
I suspect the rubber could be missing, lost during repair. Or perhaps installed wrong.

I did what you asked: There is no light coming out on the back of the phone if that's what you meant.
Anyway, I'll have to wait until I receive my replacement back housing and then I'll try my best to repair the sensor. I hope the rubber is just misaligned.
Alright - so I did have time today to disassemble my phone (got the replacement housing last week).
I noticed that there was no rubber part on top of the light and proximity sensor, as well as on the device above the two (i don't know what that is).
What I did is that I had a small tube like this one: https://sc01.alicdn.com/kf/HTB1hBgwKVXXXXcvXpXXq6xXFXXXY/8mm-small-clear-plastic-PC-pipe-TUBE.jpg which I painted black and put it on top of the approximity sensor.
Everything is working well again (there were some lints on the display right below where the proximity sensor is located, that's probably why it stopped working from one day to another).
I guess the main function of the rubber is to protect the sensor against dust and lints.
I also am very mad at myself for having forgotten to take out the NFC antenna from the old housing before replacing it, so I had to open my phone again after I did already close it (and now there are slight traces of an opening - again )
But apart from that everything's fine now and I hope it'll stay this way.

Glad you got it fixed! And yeah, unfortunately it's nearly impossible to remove the back cover without leaving dings at the injection site. When I put on my new top and bottom rear covers I removed most of the glue. So next time I can remove them without much trouble.
I am having similar problems. I just traded for a nexus 6P and everything works great except for the proximity sensor. The 6p was just OTAed to 7.0 and I only unlocked it and installed TWRP. No other changes and no root (yet).
There is no screen protector on the device.
When I make a call, the screen stays on. The screen turns off as soon as I cover the proximity sensor. The screen then does not come back on until the call is completed. I downloaded a bunch of proximity apps, including Proximity Sensor Finder. Proximity Sensor Finder (and others) report that sensor detects Far (5cm or more) and Near (value of 0 cm when the sensor is covered). The sensor doesn't seem to identify intermiate values. The odd thing is that the sensor doesn't seem to reset. If I cover the sensor (value of 0 cm) and remove my hand, the sensor continues to read 0 cm.
Does this sound like a hardware or software issue? The device appears to detect both the near and far states, but doesn't return to far after the sensor is uncovered. Thanks for any help.
Solved the problem. I downgraded to MM and the proximity sensor problem persisted, so I figured it was a hardware issue.
I took apart the 6P and the there were signs that repair had been performed. The screen was probably replaced previously. The little rubber gasket covering the proximity sensor was missing, just as the OP described. I cut a blue-colored straw and placed it over the proximity/light sensor. Works perfect!
I need to bump this thread cause a few days ago I started having the same problem that nickfuzz describes.
Now I've got my opened phone in front of me and tried putting a pice of a black straw around the two sensors, but that does not help. It reports 5.0 cm and if I cover the sensor it stays at 0.0 cm
Can anyone give me an advice about what to do now?
Update:
The light sensor is also not working properly: It is reporting way too less lightness, and tends to report 0 lux when I'm not directly holding the phone under a lamp (for instance).
After 5 hours of trying I somehow managed to at least get the sensor to always report 5.0 cm. That's better than constantly reporting 0.0 cm.
I put a piece of a wide straw (there are different sizes, you know) around the hole board on which the two sensors (light & proximity) sit on. I guess this is a bad idea.
I am now trying to get this rubber gasket from somewhere, but I guess I'll have bad luck since I'd have to buy a defective nexus 6p from which I could take it from
UPDATE:
Can anyone tell me why the screen is painted black on the inside, right where the proximity sensor is located? I scraped off the paint and painted it over with a black pen. That must be the reason why the proximity sensor is always reporting 5.0 cm (which doesn't make much sense, because at some point it would have to detect something if it's not broken).

Can you tell me if you put the straw around both sensors and their "chassis" (that black thing they sit on), or did you put the straw only around the sensors (i.e. on top of the chassis)?
I still need to find a way to fix my sensors
I tried to use some electric tape and put it on top of the sensors with two small circles cut in, but eventually I figured that the problem actually lies in the black paint on the inside of the screen.
I removed that paint a few weeks ago and I couldn't paint a new black paint on it that is not too thick, so I am stuck with a sensor consequently reporting 5cm.
I did try to use an Edding.
I had the same issue with the proximity sensory and a new 6P, but fixed it with this: https://play.google.com/store/apps/details?id=com.mobiledirection.proximitysensorreset&hl=en
Everything was still good after uninstalling that app too.
