Red led is permanently on. That's quite common for Defy MB526(5) owners after vapour and humidity under the screen. Other models also face an issue with red led. There are discussions over proximity sensor and battery might be a reason for Red led weird behaviour. Here I am trying to clarify and ask whether ultrasonic bath can be helpful. Except screwing hardware there was an idea to put the phone into ultrasonic vibrations. Probably that helps to get rid of micro particles left by water (sea water) and minerals and salts. Is there anyone who had tried that or supported these measures?
There are some ways possible and not checked on practice:
1) freeing a screw behind the proximity sensor on Defy
2) placing device under supersonic waves to clean the sensor
3) switching off (red led) proximity sensor at all via software
If you have faced red led permanently on and/or you have fixed it, got any ideas pls place a comment with your ideas!

I now own two defys, my original (mb525 non plus version) well and truly battered ( but still working - just ) defy and a brand new one (defy+) from Three ( uk mobile phone network opperator) who are/were selling them off unlocked for £69.99
Way back in August of 2011 my defy got qwet, and was then dried out in the sun - it didnt like it and the red LED came on ( not at full brightness) - there was also some misting around the LED/proximity sensor, and the top left of the screen - see post here
http://forum.xda-developers.com/showthread.php?t=1209041&page=2
The Dim red LED light never went away, and its still there. However after a few years, in the top left of the screen there appears to be a lot of dust/white specks between the glass and the screen, just enough to iritiate when its being used in daylight.
As i now have two defys, at some point when i have time I will dissassemble my old Defy to see what damage ( if any ) has occurred.

Looking forward for that! Pls find your time ASAP. Led on my device isn't dim. It is rather bright working at full power which is annoying.

My girlfriend is having an issue with what I think is the ambient light sensor. When she makes a call the phone immediately goes dark on the screen. When she wants to end the call, she has to mess around getting the screen back on to end the call.
The phone is completely stock. This problem may have only began after completing some over the air updates but we only the phone a couple of days before then.
Do you think this is a software problem? I will have no issue rooting the device to load different ROMs, but if I brick it I think I will lose my man parts.
Bump.
Has anyone else experienced this?
It is called proximity sensor. Check an app called proximity sensor finder and test it.
The sensor is located about 1cm left from the htc logo.
Sent from my One X
Does she use a case?
Happened to me when I used a case that interfered with the sensor. The sensor is smart enough to cope with dirty display and different ambient light (or IR) levels, but a case messed it up.
You could try this one
https://play.google.com/store/apps/details?id=com.incredicontrol.ProxSensorCalibrator
It require ROOT. And one more thing even that app is for HTC Rezound, people with other HTC phone still confirmed that it working with their phone.

hi all!
please help!
after screen change my phone just charging at least led shows green and red light but do not switch on.I can see just white shadow for 3 sec approx.I bought lcd with digitizer mounted together.I do not know what to do...
did you do it yourself? is your screen an original spare part or a replacement?
could not be a light sensor bug because it's only active after booting android and you should at least see your bootscreen. either faulty cheap counterpart or installation gone wrong. take it to a professional phone repair center and let them fix it. that orange ribbon/connector assembly at the bottom of lcd is a very fragile part and if handled roughly during installation it could snap some ultra thin wires so signal to the leds gets through but no image.
i've done this before but I'm not an expert, maybe someone could tell if new lcd/digitizer in sony requires firmware changes? you won't do much in recovery but you can still flash something with flashtool which only requires you to see led status and one button. good luck.
Hi everyone,
I've had my Desire Z for little over 2 years now and two months ago (was running CM7.2 at the time) I started getting a weird issue where my touchscreen would only be responsive when the keyboard was slid out (so the opposite problem of what quite a few other people have reported where the touchscreen becomes unresponsive when the keyboard is out). The status LED would also stay off whenever the keyboard was closed, and the keyboard backlight didn't come on anymore at all. Also, I had to make sure that the keyboard was slid out during boot, if the phone booted without the keyboard out the screen would not become responsive at all until after another reboot. My earpiece speaker stopped working around the same time so I was wondering whether it was just an issue with the flex cable becoming a bit loose, but the touchscreen would consistently start working again when I flipped the keyboard out, and also the physical scroll button on the top bit would always work, so I was still hoping it would be some weird software issue.
I then upgraded to Flinny's (amazing) Andromadus ROM (build 22, complete data+dalvik wipe) after which the keyboard backlight started working again, but the rest remained pretty much the same. Since then the touchscreen issues have been getting worse, so that I sometimes have to flip the keyboard in and out again a few times, or turn the screen on or off with the power button several times before it becomes responsive again, but then it tends to work fine until I lock the screen again, with no noticeable dead spots anywhere on the screen. I've had days where it worked all day without problems (except having to flip out the keyboard, that's been a constant for the past two months), and then today I haven't been able to get the screen to do anything at all even after dozens of reboots.
I've already bought a new digitizer and am all ready to put it in (I'll have to replace the broken earpiece anyway), but was wondering whether anyone has any thoughts on whether it could still be a software issue after all, or if anyone has experienced anything similar? The thing with having to flip the keyboard out to get not only the touchscreen but also the status LED to work is just so weird and makes me doubt that it's a pure broken digitizer or lose flex cable issue, so I'm wondering whether it would be better to first try reverting to a stock ROM before taking on the messy sticky glue stuff (I should be fine but still, never done it before)?
Many thanks!
From what you describe my best guess would be the main flex cable is what needs to be replaced. Flash a touch based recovery and see if you have the issue there as well, if so its very unlikely that its anything but a hardware fault

Thanks for the heads-up, I've been playing around a bit more with software and I do manage to get the screen working again occasionally, typically after the second boot into a newly flashed ROM or restoring a backup, and only until one or two reboots later when it becomes completely unresponsive again. I've tried CM 7.2.0 as well as Flinny's Andromadus 10, and it is only complete flashing that does the trick, cache wipe or factory reset alone does nothing. The two occasions where the touchscreen worked were still limited to when the keyboard was flipped out, and it also had to be flipped out during boot, otherwise nothing would work. I've learned to navigate my way around the phone by just using the hardware navigation button, but I'll have a close look at the flex cable when I take it apart to replace the earpiece speaker tonight...
Hello,
so I took my dear phone apart yesterday to replace the broken earpiece - everything went fine but after reassembly the replacement earpiece isn't working either, which leads me to think that all those little broken bits might actually be related to some contacts being a bit lose, all in the same region. Should've thought about that earlier really since the earpiece and the LED (only works when keyboard flipped out) are both in that top region that the digitiser data presumable also has to run through before passing through the flex cable.
In any case, I also took a picture of the flex cable which is slightly bent but doesn't seem straightforwardly damaged (see attachment, that thing on the right is *not* a rip). Think it's worth trying to replace it anyway?
What was truly bizarre is that after the first boot following reassembly the touchscreen worked quite consistently for the entire evening - I thought I might've fixed a lose contact by un- and replugging the digitiser cable, but then the screen went nonreactive again at some point. I wonder if the working screen was again actually related to some software reset caused by the battery being taken out for so long? In the meantime the actual screen and trackball are still working away perfectly. Bizarre.
Just to let people know the solution to the mystery: the increasingly odd behaviour was actually caused by an initially small rip in the flex ribbon cable that got bigger and bigger - it's actually half-visible in the picture I uploaded above, only that the rip is where the cable comes out from underneath the case, and not where it's wrinkled!
Just in case it could be useful for anyone, here's the (top half of phone) components in the order in which they failed on me, which I guess corresponds to the order of the respective data lines in the ribbon cable (from the top of the phone towards the center):
environment brightness sensor (I thought that the sensor had been broken for almost a year, but as soon as I rebooted with the new flex cable I noticed how my phone stopped shining into my face at full brightness - if your brightness sensor gets stuck reporting the same (low) value this means your flex cable is on its way out!)
earpiece speaker
status led
touchscreen
screen (non-alignment with edge of screen, visual artefacts)
screen (fade to black/power interrupt)

I'll for sure keep that in mind. Mine is still going strong for the time being, but it's good to know some warning signs if I need to replace parts or if it's time to get a new phone

Replacement parts all the way, the repair was 15$ and it feels as good as new! Well, it could do with a new battery but that's just another 5..
Just realised that the proximity sensor should actually be added to the very top of the list - just noticed that faint red light when taking a phone call, don't remember seeing that in almost a year :]

That's not a bad cost at all. I know I'm going to have to replace my keyboard in probably 2 months or so (maybe sooner) because some buttons are starting to not work. Other than that fact my phone is currently still going strong for being going on a 3 and a half year old phone
is it possible that the sensors will stop working if htc one m8 get dropped from hands?
the main thing is i have dropped my phone, the display was showing white, now the display is fine but the sensors are not working?(htc center chnaged display and in short spoiled my phone)....
they saying ROOT is reason for having this sensors problems
anyone willing to help me heree?

Which sensors? Proximity? Light?
Ive bought some cheap knock off screens to repair my own phone and all the sensors are on the replacement piece. They must have missed a connector or given you a bad part.
On the knock-offs, i had a proximity sensor not work and the light sensors are not that great.

light sensor,proximity sensor,G-sensor(which causes motion launch),camera flashlight all are not working when htc service center changed my phone's display.
are the sensors available only on the display part?, then they replaced display with fake one nd took money about 8500 INR
they are giving me **** reasons that phone was rooted, i told them there is no relation between display,sensors and ROOT.. i have lodged case against them will see what happens, HTC services in india are very very bad..
Yeah, probably a knock off screen. The screens would cost me about $65usd. If the touch digitizer (the top glass) edges start popping up around the bottom edge, then it's definitely a knock-off screen because all of mine did that. Crazy glue helped with that.
I've never heard of a HTC service center that you can take your phone to. Usually you mail it to HTC.
The phone isn't very easy to take apart if you've never done it before. You must disassemble everything to replace the screen. You can google a youtube video to see how it's done. Not easy for a first timer.
My guess is they messed up or missed connections. I can't remember, but I don't think there is a separate connector for flash, so for the camera to work, but not the flash, is odd.
It is possible for you to disable some sensors with root, but not accidentally. You'd have to manually disable.
I'm not too sure where the g sensor is on the phone.

thanks for your reply, let forget the flashlight but what about light,proximity and G-sensor, even i had htc desire (old one) rooted from 6 years no sensor problem till
and this flagship phone one m8 giving problems :v
the Display material description is "FRU-SUB ASSY, LG DISPLAY,BLACK,LCD" which costs me for 8.5k i.e ($127.877) , even the phone i gave to htc service center which is authorised by HTC, i didnt tweaked phone it was S-ON, i didn't opened phone lol, i just told them to change display but now things are messed up, i did complaint and they took my phone for revision from last 2 weeks ,no phone calls from them nothing, all they telling are bull**** reasons and causes
can you please tell me where G-sensor is by searching or asking someone
even didnt tweaked any hardware part of my phone, the firmware was of HTC in my one m8 , what should be the problem ,? they really messed up with my phone.....i told them that i need replacement of phone(like apple do) , they are contradicting their statements too, they told me to change motherboard which costs around $245. what the hell
due to such poor service in india HTC need to improve their services or people will stop purchasing HTC in india
If they are authorized, call HTC directly. They can probably step in to help you

nope they dont know anything, they are technically illiterate man, i have called them thrice, they are telling that go to fastboot nd factory reset it, they are noob people,
i have lodged case against htc center, will see what happens tomorrow, they are not listening, its not time to talk and request them , its time to take action against them...
i actually fade up from 2-3 weeks for this phone, thanks for helping though
Hey man were you able to fix that problem? My phone has the same problem (sensors and flash) after I got the battery replaced. Funny thing is that they're also saying it's because of root ( of course it's not )

Hello folks, i think i solved this issue ... i have a htc m8, just like all of you .. I had a extra battery so i was like. okay its time to replace this one and use this "new" battery i have for this phone. I saw so many videos on internet about tearing it down ( i had exp opening stuff before) I did it without problems actually. When i finished, i found myself with no sensors at all... none of them .. after some hours of digging. I noticed that this problem came along "display replacement, and battery replacement" .. later i found that all the sensors are in the display itself.. Then i opened it again and swaped the old battery and make sure i did connect everything. When I finished, i find myself with the same problem.. and a new one.. my screen was blinking rapidly ... i was like, rlly bro ... so i opened it again for third time.. and this time i saw something i ignored before... every ribbon was protected with a special tape, which is metalic like in the upside, they lost its glue and became loose, so i glued with a soft glue them back in place, for what i know, they do a job, something with faraday cage .. after i secured every "Tape" of this... i closed back my phone and TADAHH... i recovered almost every sensor xD ... my gyroscope is kinda weird. takes sometime to respond.. but i will leave it like that. most important for me was the light sensor and proximity sensor which are working perfectly ... well guys, that was my experience with this phone.. for those who are brave enough to open this challenger phone.. pay attention to these details i said before, and maybe you will get your sensors back.... thanks for your time.. i just made an account to help with this issue
Hi there,
I tried to open my Xiaomi Mi5s in order to "clean" the camera lens, for some (no) reason some dust went inside the case. So... I followed a YT video where I slighty warmed up the device with a hairdryer (to warm up the inside glue), removed the screws at the bottom + SIM card, and started pulling things with a lift pump (don't know the correct english word for this tool, should be clear though I think).
Unfortunately the display itself got released from the main board, the main board remained in the case. That was not intended obviously. I realised this quite early fortunately, and the cabling from the display to the board was not folded at all or something, so I pushed back the display straight away, brought it back into the original position. But then the sensor at the bottom became hot for a few minutes, and the devices cannot be switched on any longer since (only the LED at the top-left blinks "red" from time to time, like every hour or so when having the device connected to the power).
So... this is the current situation. I assume there might be a short circuit although I cannot see anything obvious. Before I dump the phone... does maybe anyone have an idea what I might need to check/try/fix?
Any idea is welcome,
Kind regards, mistersixt.
