Camera Light Problem - Its constantly on/flasing & wont - 8125, K-JAM, P4300, MDA Vario General

Hi All,
Ok the topic is supposed to read "Camera Light Problem - Its constantly on/flashing & wont stop"
I think ive got a hardware fault with my O2 Mini s (wizard). Recently the camera light started to just turn on and stay on no matter what. Right now the thing is flickering on off, and staying on solid. There is no pattern to it at all.
If i go to the camera and enable/disable the light, shortly after turning the light off it comes back on and flickers again. I cant stop it.
I have noticed that it doesnt require my phone to be on at all. If i turn it off and remove the battery, then simply put the battery back in without turning it on, the light comes on. It comes back on as soon as the battery is connected.
Do you think there is any solution other than contacting O2 with a hardware fault? (only had it about 2 months).
Cheers,
D.

It's a hardware issue for sure.
Try shaking the device, maybe youve got a small particle short-circuiting the transistor.
Or maybe you got moisture in your device.
I bet it's one of those causes.

No LED on answer/hangup buttons on hinge

Hi,
When i first setup my Exec using personal mode, the answer and hangup buttons on the hinge woudl illuminate when a call came in (when the unit is closed like a laptop). Now i am using it in corporate mode, the LED's don't illuminate. They only illuminate when the screen is rotated into PDA mode.
I am assuming this is a reg hack. Does anybody know what it is? or has anybody else got this problem?
Cheers

They don't illuminate when the device is closed, only when you have the screen open or facing outwards.

And very annoying it is too - especially when both buttons look so similar when not illuminated. This must be hackable?
This has got to be one of the most annoying features of the exec.
Also i have found that if the device is closed, MSVC does not recognise anything you say when activated via BT.
I have never really played with the device in personal mode as the GUI is bollox so cannot comment on if the buttons light up or not when the device is closed. But what i do know is that when it is closed the screen is switched off as if the device is in standby mode, maybe this has something to do with it.
I try to memorize the position of the green button in relation to how I always hold the phone and feel for it like a Braille board. So far I get it 75% of the time.
is anybody using the 'Personal' install on their exec? can they confirm if the LED's are illuminated or not when the phone rings when it is closed?
Cheers
Paul
Someone who's actually opened the Universal may be able to confirm this, but I suspect that the answer/hang up buttons on the hinge don't actually have LED's. I believe that they simply use the light from the screen's backlight to illuminate. As near as I can tell, they're only on when the screen backlight is on.
If that is the case, then there probably won't be a way to get them to illuminate when the case is closed, unless someone can figure out how to get the backlight to stay on when the case is closed (which would also be a big battery waster)
Brett
Yup, i can confirm this. I've just removed the cover on the top of the hinge. There is one wrapped cable coming out of the base at the right hand side. This then splits off, the main part goes up into the pivot hole, and a thinner wrapped wire brakes away from this and attaches to a small pcb which has the buttons and the LED's mounted on it.
Yes, the buttons are only illuminated when the backlight is on, but the brightness of the buttons remains constant even when the backlight brightness is turned down.
Cheers
Paul
As far as I see it, even if the backlight has to come on that wouldn't be a problem - after all, the phone is waking up in order to ring. I also often open up the screen slightly to see who's calling, then close it and press the answer button - therefore switching on the backlight initially would actually save time!
Maybe somebody knows of a "wake-on-ring" hack :lol:
I've just noticed it with my new Qtek 9000 and I was very worried, because I thought my device is broken.
But now I know this is "normal", but it's very annoying :?
I wish I had this problem! .. since yesterday my JJ seems to have those lights permanently on even when I switch the device off
Guys, I've made a program that will keep the hinge leds on all the time.
Actually this is an accidental discovery for a program I'm working on for this thread:
http://forum.xda-developers.com/viewtopic.php?t=37201&highlight=
Those guys want to be able to use the keys and phone functions with the lid closed.
I'll post more in that thread, but basically closing the lid puts the hardware keys in a special state such that they are not responsive at all until the device is woken internally (eg by an incoming phone call). Actually, can someone confirm that the hinge keys work when a call comes in but the lid is closed. I presume they must, since they don't do anything else!
So, the hinge lights are on when the screen is on. But the screen is switched off when the lid reaches about 10 degrees to closing. But the hinge lights can be kept on nevertheless
Grem: are you using TCPMP or a similar program to play music etc in the background? Anything that tries to keep the phone "on" when the lid is closed will keep the hinge lights on.

Hi vijay555
I've actually just done a complete cold re-boot and reflashed to the original i-mate factory ROM to see if that would help, then came here in search of anyone having a similar issue.
It started yesterday, i suspect I've had an internal meltdown somewhere, plugged it into sync, noticed a few minutes later it had randomly done a warm reset and appeared stuck on the blue i-mate screen, picked it up and the sucker was hotter than an AMD without a heatsink! I suspect it's warranty time for this unit
Grem, that's worrying. What were you doing at the time? What brand/operator etc is the phone? It might be worth posting batch numbers or whatever for people that have this kind of problem so we can identify if some are worse then others.
V
It's an i-mate straight from the wholesaler no particular operator. Had it a couple of months, have seen other reports on the forum here which sound perhaps similar in that they've overheated.

SPV M3100 keyboard backlight, does it have one or mine dead?

Hi,
I got my Orange SPV M3100 on Friday and already i've noticed what i think is a hardware fault. Not a big fault and i totally love the phone (Skype over wifi an encrypted connection works perfectly), but i'm worried as the phone is only a day old.
The first few times i opened the slide out keyboard I thought i noticed a nice blue keybourd backlight come on. I say thought as i can't find any reference to it in the manual. However whatever i now do, i can't get it to come back on. I've installed a few applications, but i doubt they would have caused it to stop working.
I don't suppose anyone else out there could tell me under what situations the backlight should come on (or if one exists), so that i can test it, and if it doesn't come on, i can phone up and get a replacement sent out. Its not a big problem and i can still use the phone, but you don't expect hardware to die after only a day.
Thanks in advance for any help you can give me.
Neil
there's a small hole in the top right of the keyboard. This is a light sensor. So, if light's on your keyboar led will be off, and if it's dark your keyboar led will be on.
you have to press a button too before it comes on iv found.
there is a setting for it as well somewhere to turn it on
Thanks for the advice guys, but the keyboard still doesn't light up if i open an application that asks for text to be entered and then slide out the keyboard in the dark and then press a key. Looks like my light sensor has died. I've just phoned Orange and they are sending me a replacement for between 6 and 10pm today (what fantastic service!).
Same issue over here
Hello I am experiencing the same problem over here.
It worked for the person who sold it to me and now it does not anymore.
Do you know if this is an HW or SW issue ?
Any other cases around?
TX
seems I have the same problem. i'm on orange and the light was working now it doesn't.
EDIT: no i dont have a problem. I went into a dark dark room and then typed something and it worked. if i cover over the "light sensor" with my finger and press a button, it doesnt work.
Indeed
Indeed I had a wrong interpretation of the function of the sensor:
The sensor works in the following way:
If it is dark AND there's a key pressed AND the setting in "Settings" is set to enable sensor THEN keyboard backlight is turned on if no light in evironment.
If the setting in "Settings" is set to enable sensor THEN keyboard backlight is turned on AS SOONS AS you press a key.
A little dumb from my point of view: if I slide the keyboard in the dark, is it to look at it in the obscurity? The simple sliding should turn it on by night.

I've noticed that the backlight on mine (Vario 2, it's a red backlight... urgh) doesn't come on all the time if it's dark or dusk-level, which is really annoying. Sometimes hitting the tab key brings it into life, but sometimes it just doesn't come on at all.
One of those 'temperamental', 'great idea in theory' designs methinks.
I also found out that if the turning screen backlight off on inactivity is disabled, then every time I slide out the keyboard, its backlight is turned on.

G1 Screen problem

Hello, My G1 has just suffered a problem, i was scrolling down a web page and the screen faded out like it had lost power but the backlight was still on, the keys lit up and it still could make the trackball clicking noise when you moved it. I took out the battery and left it for 5 minutes and rebooted my phone and the screen turned on for about 3 seconds and faded out like before but it did boot into android as I heard the notification/startup sound. I think that the screen has burnt out but im not shore so has anybody had this problem before and/or might know how to fix it
Just some more infomation, If the screen dies and I leave it for a few minutes, when I unlock it or slide the screen up, the screen works for a few seconds but then fades. Also the fading looks like the screen lost power or like its losing pixels
From my experience with phone hardware this doesnt look like screen problem, but rather the lamp driver in the motherboard. the only way to narrow down is test the motherboard /screen with another phone.
If this is the case, it might require servicing the backlight driving circuit, which by far requries soldering/desoldering some components in motherboard.

had the same problem its a hardware issue. tmobile sent me a new phone no questions asked
Thanks for the replies, it seems that it has fixed its self as I've been using it for about 5 hours and no problems so far, I'm using it right now to type this, if the problem persists I will try and fix it or just buy a new one

No Wake-up after phone call

Still tested different NAND-Android Roms on my HD2 but got still a problem. If i make a phone call and the screen turns black while calling i press the endkey to end the phone call. But instead of turning on the device, the screen stays black and i need to pull the battery and restart the phone.
If i make a phone call and use the free speaking funktion, while the screen don't turn off, i got no problem when ending the phone call.
I don't know what the problem could be, but it seems, that the thing has to do with the sensor who turns the screen on and off. But i don't know if this is the problem and/or know how to fix this problem. Like i said, i tested different Android Roms formated the SD-Card, deleted cache and all the stuff, but nothing fixed this problem. :-(
28 Views and no one with this problem? :-(
There are 2 other threads discussing this issue already. Here is one.
http://forum.xda-developers.com/showthread.php?t=946012
Issue lies with the light/proximity sensor. Could be defective hardware. Could be incorrect sensor drivers. Could be dirty sensors. I have yet to take mine apart to check for dirt on sensors. Blowing into the led/earpiece opening seemed to help. I notice if it doesn't come back on I can hold a very bright light (ex: cigarette lighter) about an inch away and the screen comes on as long as the lighter is lit. Sometimes it stays on.
thanks for your answer. seems to be more things to test and maybe solve this problem. Thanks!
THANK YOU Agoattamer!
Your link helped me to solve the problem! I just cutted a little piece of my screen protector, where the proximity sensor is, and got no more freezes after the phone calls! The screen protector still got two holes for the light and proximity sensor, but this seemed not to be big enough. Anyway, thank you a lot for your post!

I also tried a a lot of different NAND ROM and I had also this problem and I can't use Android efficiently. Now I am using hyperdroid ROM ( first GBX now CM). With this ROM and sanity app (from market, with correct settings you can find with trying) I almost solve this problem. ( probability of 95 % I don't get this error)
hey guys! i found the solution goin through the market!
download an app called "Sanity" theres a free version in the regular android market.
go to the settings > general > check "Reverse Proximity" (This will give you some warning about not using it if you DONT have a buggy proximity sensor). Check it anyways. Then go back to preferences then click "Proximity" scroll down and uncheck Turn off screen and leave leave the Turn on screen checked. this will force your phone to stay on during calls so that it never has to go through the proximity phase of calls this no more black screens. Hope this was helpful ^_^

Always on 2nd screen in the dark issue ??

I bought a used V20 with a defective screen. I change it, everything work for fine, but i notice a strange behaviour with the second screen.
The second screen is always on and i can unlock it by only touching the finger print sensor. BUT at night (or in the dark), the second screen turn off and i need to press 2 times on the power button to wake the phone.
The Knock On feature doesn't work too in the dark.
The light sensor seems to work correctly.
I would love to post a video but i can't......
This is an issue or it is normal ??
Thanks for your help !
Sounds like Doze.
I don't find anything related to Doze or "standby" about this screen.
check "daily timeout" on Show when main screen off. Seem u turn this function on at night

Sounds like there is an issue with the proximity sensor (not light sensor).
It's setup to turn the second screen off as well as disable knock on if the phone is in your pocket. Even during daylight hours if you put your finger within an inch of the sensor when the main screen is off, it should trigger it.
It seems your sensor may just be messed up.

There are a few apps on the play store you can try to fix it if you are rooted. You could also try a sensor app to see if the proximity sensor is showing feedback properly although you might need to be rooted for the apps to show the proximity sensor properly (not sure). My note 4 had a hardware test in the service menu not sure how to do it on V20 though.
Same Issue
Edit: Resolved the issue. Please read this post. There is a small rubber gasket-type thing that sits in the hole of the phone's frame where the proximity sensor is positioned. That rubber gasket was not included with my replacement screen. I pulled the rubber piece out of my original, broken screen, and installed it into my replacement screen. I am no longer having issues with the phone in the dark.
I am experiencing the same issue. I have a T-Mobile LG v20 (H918) and I cracked the screen last week. I ordered a replacement LCD assembly and installed it myself. Everything works fine during the day or in a well lit room, but at night, in a dark room, I experience all of the issues you are reporting. I am finding other posts online with our same issue, but as of yet, no resolution.
Even though the second screen is set to always be on, at night, in a dark room, it turns off almost immediately after locking the phone. It is almost as if the phone is in a "deep sleep" or something, because the following also occurs:
Knock On will not wake the phone
Fingerprint sensor will not wake the phone
Even connecting to the phone via AirDroid / AirMirror the phone doesn't wake
Need to press the power button multiple times to wake phone
Providing a light source immediately turns on second screen and resolves all issues
