Hi my problem is strange. After a fall mi phone HTC GRATIA is similar HTC Aria have a problem during the call. Sometimes the display became black similar a stand by and not answer to the all impulse. If i want stop the call i have to do remove the battery.....
Have you any help for me ?
thank you
I've got a similar problem. I've replaced my digitizer and done everything by the instructions I've found. However the proximity sensor doesn't work and disable the screen when calls are answered.
I've got the rubber gasket on the light sensor, didn't lost it, and the light sensor works OK. I've tried prying very gently in between the digitizer and the housing, and while I do that sometimes the proximity sensor will show a value of 3.5in, and not 0 as always. I'm using AndroSensor.
I don't mind disassembling the phone again, but I don't know what I need to fix it.
I've searched all the forum posts about it, but either people disabled it somehow, and others just say they fix it but didn't mention how.
Any help on this?

You need to get the light sensor, gasket, and the small window in the digitizer all lined up perfectly so that the light sensor is not being blocked by anything. Not as easy as it sounds.
thanks for the explanation, but is the best way to do this?
and why the light sensor shouldn't be blocked? it seems by AndroSensor that it works fine, the problem is with the proximity sensor.
These phones where manufactured by the thousands per day in some factory, there sure is a way to assemble them precisely somehow.

If it is blocked, then it will not be able to sense anything (It's like you (the light sensor in this case) are trying to through a wall (whatever's blocking it)).

Special machines used to place them accurately.
I meant that the light sensor is "blocked" by the rubber gasket and seems to works fine.
by the way, as far as I know, most electronics are assembled by hand. laptops, iphones and ipads are, so I don't think that Aria is any different.
If anyone has any tips on how to do this, since I'm sure I someone has managed to replace the digitizer on this phone? how do they do this in repair shops or AT&T store?

The ambient light sensor and the proximity sensor are two separate things, though they are right next to each other on the Aria. The proximity sensor is MUCH more sensitive to being precisely aligned.
I incorrectly used the term "light sensor" in my earlier post. The proximity sensor, NOT the ambient light sensor, is responsible for turning the screen off during calls.

That's what I assumed you were talking about.
As I've said the proximity sensor is the right sensor and the ambient light is the left sensor that is covered with the rubber gasket.
The light sensor works perfectly as I've said. In AndroSensor at least it jumps between 33 LUX when covered and 77 LUX and 220 LUX when placed directly under a desk lamp.
But the proximity sensor doesn't seem to respond at all. What perfectly aligned means, that the sensor is right below the "hole" in the digitizer plastic? if I place the digitizer and it falls into the place, how come it isn't aligned? it's not like the digitizer has where to move in the frame.

I have two Arias and they both max out at 698 lux. If you can't get it to go above 220, it might be partially obstructed.

Do you notice a gap between the LCD and digitizer that is larger than it was from the factory? I wonder if it might just be related to the digitizer sitting too far from the proximity sensor. If you press down on the top right corner of the digitizer while in a call (without covering the sensor itself), will the screen turn back on?
Possibly unrelated, but similar.
I have an identical issue with the DroidX.
It needs a "gasket" over its proximity "light source" to keep light from reaching the proximity light sensor when there is nothing in front to reflect it back.
Looks like the light source had a rubber hood over it with a pinhole directed straight out, away from the sensor adjacent to it. Thus keeping stray light from triggering the sensor.
AAARGH. To have that little rubber piece.
Erbid
after replacing another screen and this time I've done it right, this is what I've learned.
I've assembled the phone with androsensor turned on and tested the sensors all the time. It seems that they should be perfectly clean (some air spray will do just fine), perfectly aligned with the holes in the digitizer and don't have to much distance between the digitizer and the sensors.
It's seems like a hassle but actually it's not, since if you put the right tape and put the keep it all clean, it can work with no problems at all. Make sure you test everything before you close the phone completely.
Using elixir from the market the proximity sensor is listed as being present. Where is it and why does it not display any values?

Something seems to be wrong with my proximity sensor as well..it worked before but since .13 (now on .15 and still not working)..It was working back when I was on .11.1 though.
I know this because I was trying out apps like Smart Screen Pro etc. which turn off the screen when the sensor is covered and all.
Now apps like those don't work for me anymore...and I got AndroSensor to check on my device sensors and the Proximity Sensor sometimes says failed to start, while other times it says "Waiting for event" either way, it never works now
Any help with this?
On my SGS, I had a problem with accelerometer before and I just had to delete a file and let the system recreate it and the problem was fixed. Perhaps something similar can be done with the proximity sensor since it's kinda similar to the accelerometer in the sense that well..they're both sensors of some sort lol
While it actually has a chip that supports the proximity sensor (and thus reports having one), the chip is only used for the ambient light sensor. It doesn't have a proximity sensor.

Ohhh thanks for the info! I soon realized this as well when I was looking through the apps I was testing out before.. Turns out they were using light sensor and not proximity. D'oh!
Oh well, a proximity sensor on a big tablet doesn't make much sense come to think of it.
Ya it does light sensors use more energy than proximity sensors and control via cover state is quite desirable

The Prime has a cover state sensor, its magnetic just like that other tablet it is close to the webcam. It is used by the dock to turn off the screen when you close it.
Why no other covers are using it... I have no idea.

There are some reports that the magnetic sensor only works when the dock is connected. If thats true then one would have to find a way to trick the tablet into turning on the mag sensor manually before it would be any use.
There were some people wanting to use tasker to check the status of the mag sensor for various reasons, detect if its in a case, etc. but they had minimal luck.

Hrm. No.
I have tested this already myself, going to mod my leather case to allow a small magnet on it so the screen turns off when i close it.
The right spot is tricky to find, but it is there, it works and the dock does not have to be connected for it to work.
You can try it yourself, get one of those weak magnets from the freezer and put it around the frontal camera until the screen turns off. Just remember to deactivate the auto-off timer first
Nope. It does not have one.

Can you post a pic with the EXACT placement if this sensor, if it exists?
I have rubbed a magnet over every inch of my Prime and the screen never turns off because of it. With regards to the dock it makes much more sense that a mechanical switch would dictate when the screen turns off, since this would be more reliable and since the dock hinge can function like a switch, and the dock plugs directly into the tablet usurping certain tablet functions so it wold be easy to make the dock take over the function of the power button in certain conditions.

It makes absolute no sense to use an ambient light sensor to turn off a screen. Going from a room or a place with a bit of light into a dark room would turn the screen off.
There are 2 holes on the top of the prime bezel. One is the frontal camera, the other the light sensor. The magnet is not there.
If you are facing your Prime it is to the right and a bit down of your frontal camera.
The manget is in the dock right off the track pad.
You can get the exact location with a paper clip. it will stick there.
So, here is the video...
Sadly like other user noticed, it does not work without the dock Probably happened after one of the updates, cause it was working without dock before.
I found the spot myself.
On my BBOK Transformer Prime, the magnetic sensor is just to the right of the camera, but about one inch down into the screen area. If you play with with the keyboard using a magnet you can find a magnet under the right end of the spacebar.
Unfortunately I can confirm that the tablet won't turn off in this way without the keyboard dock connected.
In the app Sensor List there is listed a proximity sensor, however I have only heard of people saying the Prime has no such sensor.
The sensor is listed as: Intersil isl29018 Proximity sensor
It doesn't seem like the app can get any readings from the sensor though. Is my sensor broken or what?
Dont see why the TP would need a proximity sensor, its not like your gunna be putting your face on it !
The app is probs just detecting the light sensor as the proximity sensor or similar ..

Then how do you explain the listing of "Intersil isl29018 Proximity sensor"? Other apps list the same thing. Try it.
Elixir 2 lists a proximity sensor as well, and actually shows it as active and drawing power. But, the app doesn't show it as responding. So, who knows? Maybe proximity sensor functionality is part of a multipurpose sensor, only there's no component to actually take the required readings?
Actually, yes, that's my guess. That part number is a light and proximity sensor, and there's likely just a component to enabling the light sensor part.

Actually, you're wrong. The Prime has a proximity sensor--only it's a light and proximity sensor (check out my link above). The proximity sensor functionality simply isn't enabled in the Prime.

Wrong. There is a light sensor, but it isn't a proximity sensor. Check the FCC materials.
actually i think the prima has one.
I think it is inside the dock. Because androsensor (app from the market) gives me an error on this sensor when the dock is not pluged in.
When i plug my tablet in the sensor says no signal.
Can be a bug, but mayby the dock uses the sensor in the hinge to see if it's open or closed?
There has to be the sensor its used when you close the tablet when plugged into the dock that's how it now to shut the screen off

This could be the case, that it only activates it when coupled with the dock. However, pretty sure I haven't heard of people accidentally putting it to sleep using its touch-screen while docked, so I doubt this is the case; more likely there's a mechanical switch on the dock that let's the Prime know when to turn the screen off.
As linked above, the proximity sensor is one and the same with your light sensor (pretty sure it's like this on my phone too... will have to have a look just to be sure). We just have no need for it to be used: that being said, I wonder if dev's can unlock it just for the hell of it

Easy to prove/disprove. O have tried it when I 1st got the Prime. Put it in the dock. Close it most of the way, leaving it open about an inch or so. Put your finger over the light sensor (about 2 inches to the left of the camera) It does NOT put it in sleep mode. Close it the rest of the way. It goes to sleep. Shine a bright halogen light in to the area at top of screen, after just cracking the tablet and doc apart a fraction. It does NOT come out of sleep. There seems to be a mechanical switch in the hinge. Which I am not very thrilled about. Too easy to break, the light sensor would probably have been more durable. Another great engineering decision by Asus, going for the "Persistent Perfection" or a reasonable workaround to simulate it, LOL!

while the light sensor would have been more durable, it would also prevent deep sleep mode as the OS would have to constantly read the state of the light sensor for keeping screen off and for turning it on immediately upon opening docked tablet.
Magnetic
I think the Prime has a magnetic open/close detection system.
In a hardware thread someone observed that the Prime will switch off the screen if a magnet is placed in the upper left quadrant. And since the dock is quite magnetic right of the touch pad it seems to fit. I never tried it with a magnet myself though.

There use to be a GPS sensor listed in the specifications too. I'm guessing if it doesn't work - it will just mysteriously disappear.

Eh, I think I'd hate using a proximity sensor for this. The explanations about magnets is interesting, and definitely not an easily-broken method.
Really though, I plan to use my touch screen even when docked and would be pissed trying to swype/tap/play anything and accidentally send the tablet to sleep.
If there is no light sensor how do you explain the "auto" brightness? It has to be sensing something from somewhere. Unless we're talking about something else here.... cuz i kinda just skimmed through the posts..... >_>
In the service menu: *#*#7378423*#*# in the dialer, for this device I have found that Hall element sensor is an option to be tested however when I test it nothing happens. Holding a magnet or a case with a magnet does nothing. I wouldnt imagine that option being there if there was no such sensor within the device. The option was never apparent on my Z2 which I believe didnt have the sensor which would make sense. The Z3 has the sensor and thats a much older device than the X. I would imagine there would be a sensor embeded in this device. If possible could anyone see if it works for them. If not could the feature be enabled in a ROM or kernel? Thanks
I bought a case that's supposed to turn screen on/off when opening/closing. But it's not working.
How can I check if it's tablet's problem or case's problem?
Maybe this feature is broken in the android pie update?

I use this feature always on my M5 8.4. I don't have it with me to test the sensor location, but you can test it yourself placing a magnet in different places on the screen. Somewhere it will turn on and off.
Are you using stock rom?
The location the magnet test should be made (based on my 8.4) is bottom left corner of screen about 1-1.5 inches in if holding portrait. I don't know where on 10 inch model. My case is the same turns out the magnet in the case was either misplaced or not powerfull enough to trigger the auto screen off.

Head to settings to find the option to check the box smart cover, provided you have the supported cover.
It's working on mine
Finally I changed the case and in the new one it's working. So it was case's problem
