stupid question: phone lock on call, totaly locked

Greetings,
I just bought an htc desire. I do however have BIG problem.
As soon as i call someone, the screen goes dark (read it is normal) but, i CANNOT get out of the dark screen, i cannot hang up or unlock the phone, the unlock key does nothing, nor does any other key.
Whats happening?

maybe youre holding one of your fingers over the proximity sensor left to the phone output, or your proximity sensor may suffer hardware faults

the second option really does not sound too good, for a NEW phone

is there no way to disable the sleep option on call???

I don't think there is, that is a needed function. Otherwise, you would do many things with your face over the screen.
Still, my sensor works normal. If I cover it (hand, ear or whatever at the earphone), the display goes off and locks, if I uncover it the display is on and active. And I can do this many times.

i installed "show sensors" and for the proximiti sensor (cm3602) it says reading 0.0 and accuracy high, the number NEVER changes :/

I don't think that anyone from the forums can help you, it's obviously hardware problem. Why you don't just take it to HTC for repairment/replacement?
Btw, show sensors for my proximity sensor say 1.0 when I don't touch it, and 0.0 when I place a finger on the earphone. It's too obvious that your proximity sensor is off.

looks like i have no choise, im gonna have to bring it back in and wait it comes back from support, gonna be without phone for a while :'(

Do you have a case or an "invisible" shield covering the sensor?

sadly, no, its out of the box. i dont even know where is the sensor tough

It's on the left side of the earphone
Aproximate position, not sure about the exact position.

It should read 1.0 unless the sensor is covered (moving an object over the sensor changes its value to 0), so it appears that you have a faulty device

is the support of htc any good? will i have to wait long to get my baby back? anyone knows?

I called HTC belgium this morning. They made a ticket and said ill receive an email that i have to print and give to the delivery guy tomorow with the phone, between 8 and 12 am.
Now the funny part is, I STILL DID NOT RECEIVE THE DAMN EMAIL.
I called 3 or 4 times, send 4 messages via their ticket system, gave 3 different email adresses to be sure. And i STILL DO NOT HAVE IT, its been like SEVEN damn hours...
They are one hour out of closing, and there is no way ill get it tomorow before the delivery guy comes.
I'm about to go berserk right now, is it always like that with them?

Hey,
i had the same problem that i noticed after root... have you rooted or installed different rom?? Also i send it to repair what they did was updated the rom to the newest one and and restored contacts of the sensor.... but it might be only the rom if you had flashed it. If not then you have to send it to repair or exchange it.

i did not flash it nor root it

Then its a hardware problem, maybe loose connection from the sensor, in that case either repair or exchange
I feel sorry for you... I was without the phone for about 2 weeks for exactly same issue

[Q] Anyway to recalibrate the proximity sensor?

I researched about causes of phone unable to turn on after a call and saw a DHD thread about it. I tried reflashing the ftf file but after a call, the screen was unable to turn back on, therefore i think it is the proximity sensor's problem. Is there an app like http://forum.xda-developers.com/showthread.php?t=951858 to calibrate proximity sensor? o_o

Any help? After every call i have to pull out my battery and on my phone ..

I'm going through the same problem with my xperia play but I realized that if you place the unit directly in the sunlight it works, I tried a lot about some application to adjust it but it only works in some unit (not xperia) he asks for one kernel file that we do not possess even in custom kernel like DOOMkernel.
I saw this information on the sony page:
(i cannot post links, just look in google for "Sensor HAL for Xperia™ phones available as open source")
I located the file Sharp_gp2.c that has the attributes that I want to change, I imagine that if I change some values ​​like "power" or "resolution" I have some positive results but I do not know where to put this file in xperia play, I think that i can make a zip file and do a fastboot but not sure what the correct path.
If someone Knows, please tell us.
(Obs: I bought the proximity sensor part on ebay and i'll change it by my self, it costs 9 dollars and will arrive in 30 days, if this solve the problem i'll post the result here)

Hey dude, i solved my problem with proximity sensor, the piece that i order still not arrived but i disassembled my xperia play and i removed the piece (proximity sensor) an put it again and is ok now.
It looks like this:

You can see how to disassembly your phone on Youtube, i think the problem was a kind of Conductivity failure on the big conector as in the image.

Where did you find the part? Mine is doing the same thing but, I prefer to keep all parts intact so I believe I should order one. Also does the part come with the tools?

Nexus 7 2013 Accelerometer & Gyroscope Not Working

Hi,
Stock Android - Not Rooted 5.1.1
I am attaching two images here. I am pretty sure it's not a hardware problem since my other sensors are working so I would like to figure out which apps are blocking these sensors and how to fix.
A quick reboot is a temporary fix.

Pretty sure that this is a hardware issue. Two of the most common issue of this tablet is auto-rotate and touch screen. I experienced the auto-rotate issue a week or two ago wherein placing the tablet on a flat surface face down and pushing the "N" and "S" letters at the back and doing a reboot temporarily fixed the auto-rotate issue. Which if I may say only worked for a few hours.
It came to a point that the reboot and pushing the letters no longer worked. This is the time where I searched and found a hardware workaround: https://www.youtube.com/watch?v=LLCAeBe2hVU this is if you're willing and have the guts to open up your tablet. It seems that the wires connecting the accelerometer/gyroscope and touchscreen "loosens" over time. I've applied the fix a week ago and no longer experience the auto-rotate issue.
Obviously It's still best to send your tablet for repairs if you still have warranty.

I had already applied that fix so was ambient sensor working. Earlier none of the sensors use to work. But now since removing my magnetic case it seems to work fine for today. Will see how long does it last!

Actually disabling automatic brightness and removing magnetic cover has seemed to solve the issue. I am using Velis Auto Brightness and since then the auto rotate has never ever stopped.

Sensor continuously flashes while screen is off

Whenever my screen turns off, I could see (Not visible to naked eye but can see though other cameras) a sensor near to front camera is continously flashing in pink. Which sensor is this and will it consume my battery. I have the latest oxygen os version

Do you have proximity wake turned on?

No. Proximity wake is not ON

The sensor you are referencing is the proximity sensor. I also confirm being to "see" it using the camera from another phone without proximity wake being activated.

Maybe the new pocket mode checks constantly if the sensor is covered instead of checking after you touch the fingerprint sensor. Would possibly save time?

Will this have an effect on battery.
Was this check present in oxygen os verson older than 3.2.2. Also why the proximity sensor is visible only on camera and not to human eye.

You can see it in dark. It's because of pocket mode when it's in your pocket it helps to disable fingerprint sensor.
I'm more concerned about the sensor that its always active it might get damaged?

I can't check if the proximity sensor did the same thing on previous versions cause I'm running CM13 at the moment. But the pocket mode is a new implementation that users had been asking for a lot before the update.
The proximity sensor is only visible on cameras because it emits infrared light, which can't be seen by the naked eye. Cameras on the other hand do see this light (unless the camera has an IR filter, which many higher-end webcams do) but represent it on a display that only emits light on the visible part of the spectrum, hence we can see it.
The proximity sensor is made to use infrared light so that
A) it's not an annoyance to people using it, they don't see it blinking when the screen is off to check if it's in a pocket etc.
and B) so it works in all light conditions
---------- Post added at 06:28 PM ---------- Previous post was at 06:25 PM ----------
The effect on battery would be minimal, if any at all. Proximity sensors have become much more efficient than they used to be. They've also gotten better at being "invisible". For example, my old phone (a Vodafone Smart Ultra 6) had a proximity sensor that emitted infrared light, but very sloppily, hence emitted some light in the visible spectrum too, so you could see if it was turned on in the dark, which was really annoying. Not to mention a bug in its software that meant it sometimes got stuck on randomly and had to be rebooted to fix it, and that didn't even always work

Proximity sensor ALWAYS ON ?

Hi everyone. I recently bought a Xiaomi Mi Max 3, my first Xiaomi phone. It got approximately 3 major updates and is now running MIUI Global 10.3.2.0 Stable. The other day I tried taking a photo of my phone and noticed a white dot next to the front facing camera. I tried to take another photo and noticed a constantly blinking light from the same spot. It's not the notification light, that's on the left side and is noticeable with the naked eye. This one however is on the right side (next to the camera) and is not visible to the naked eye.
Upon further research I found out that it might be what I initially thought it was; the proximity sensor. However from previous experience with my Samsung Galaxy S5 I've seen that the proximity sensor is only on during phone calls or if air gestures was on. But on my Mi Max 3 it's always on. The moment I turn the phone on it starts lighting up. I don't have auto brightness/face unlock on, and also tried to turn the proximity sensor off in call settings. But no luck. It even lights up when the screen is locked/off. I don't know if there's any settings causing this, but I tried turning almost everything proximity related off (pocket mode etc.) I have seen that other Xiaomi users have been having this issue too. I tried CIT and the proximity sensor seems to be working (0 to 5cm) but fails to calibrate.
So I had a few questions
1) Is this normal? Is it normal for the proximity sensor to be always on? I highly doubt it
2) Any way to fix this?
3) Will it consume a significant amount of battery power?
*If this really is an issue and not normal, I hope it'll get fixed with a software update because I don't think it's a hardware issue. I've read that people were having similar issues after update here
I don't know if the problem existed before the updates; noticed the light recently only!
Thanks
