Dual Led flash not working - G3 Q&A, Help & Troubleshooting

Hi everyone,
A friend bought a g3 today with lollipop version, and we just found out that the flash is not working.
We tried to install a torch application and a diagnostic app. But the dual Led don't turn on.
I don't think that flashing the phone will change anything, I'm afraid that it can be hardware.
Do you think that the dual Led can be replaced?
Thank you for reading , we really need your help...

Try using camera app to invoke the flash indoors under bright white temperture light (fluro light) the orange one should light up when i take photo as it will try and add some skin tone back with more orange toned flash.
Conversely take photo in incandescent lit room and see of the white LED flash when you tale pics. The phone should try to balance out the orange tinted light with white flash.
If not and under warranty u may have a reasom to return it for repair.

thank you for your answer.
I think this is a hardware problem, and coincidentally when I try to call the seller, I fall on the voicemail.
Basically, he scammed us and I have doubts whether it is still under warranty.
You think it's fixable without changing the motherboard?

[Q] Red led permanently on: ultrasonic help?

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.

[Q] lcd change

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.

Dual LED

Hi.
I got my phone back from LG service (bootlooped, they replaced motherboard).
But since its back I noticed my led flash isnt working. Only one of them (top) is flashing. Any solutions?
Or should I send them it back again? Idk if its worth wasting time cuz I guess its no rly diference with 1 or 2.

Check by taking photos in white fluro lit room as well as yellow incadescent light. There is a difference between the two LED, you should see the plastic lens one is yellow and one is orange. These two work to balance out the colour of environment so there is a reason to have both working.
Also check by using a torch app.

LED notification not working

Hey Guys,
Just received my P8000 today and its just amazing. The only thing I am having the trouble with is the LED light. Its just not working at all. I have updated the SW, Rebooted it but I cant get it to work, I have tried testing the LED with Lightflow app but it doesnt glow. any solutions?
Let me guess: it's either white or gold.
If so, chances are that your device comes from the very first batch of P8000. And all of the phones from this batch lack that LED. There's nothing you can do, except maybe to ask your vendor for a replacement.
I myself am biting my nails while I'm waiting for my unit to be shipped, although I ordered a grey one (and supposedly not from the first batch of white and gold units only, as the rumor goes).

Its a white one indeed, this is extremely strange that certain colours dont have LED. I mean what kind of manufacturing process is that
I'm also waiting for this LED issue to settle down before ordering. I really like the phone but I definitely want it WITH the LED notification.
I will most probably buy from aliexpress. How can I ensure that the phone I buy is from the new batch and has the LED.?
buy the grey one or wait two to four weeks

you could try asking the seller as most do test the phones before sending out so worth a try..

No notifiction light here neither. Mine is gold....
Got me a white model. No LED indicator. Given the price, shouldn't really matter but maybe there will be after market parts to buy and install the LED indicator(?).
Mine is golden and it's got the led notification, so it's not only black phones that have it

if you're successful then let us know how it's done!
I got my phone today too. A grey model from geekbuying. I don't find the led. I download the led color change app and when i test the middle button flashes that blue color. Should I assume that mine came without led as well?
White model here as well. No LED as well...
@pelloplasma: The center button IS the notification light when it flashes there is a notification.

yeah, lucky you! but you can't change the colour - that would be asking too much!
Yes, for 150 buck I paid it was tough request to have LED in my phone, infact who the hell does want LED notification these days? who would ever want to know when ther's an unread message waiting or a lost call?
p.s. for 3 bucks more I would have loved to have LED in it, ****, with the chinaphone there is ALWAYS something little that you miss so much...
My LED light works but it doesn't flash when receiving a notification, any ideas how to enable it? I've checked settings.
Hi,
Is there any parts avaiable to have LED indicator for P8000, my phone if the first white series to.
