Hello everyone .. A few days ago I bought a second hand Huawei Mate 20 Pro, and I have issue with LED flash.
The camera itself is okay, but when shooting with LED flash on (and LED flash always on), the pictures are practically unusable, it looks like some kind of bluish filter is enabled, but it isn't.
Also, the same problem when I swipe down and turn flashlight on from the notification bar.
Is this a software or hardware problem ?
I did a factory reset but nothing.
So, this is what I'm talking about:
https://ibb.co/YhCv920 --> Flash OFF
https://ibb.co/gSdKjk1 --> Flash always ON
https://ibb.co/3YtPN7x --> Flash ON
Bump ..
Any fix for this, advice, suggestion anything ?

Hello,
I just got the x10 mini pro and one thing pretty annoys me. In camera i have flash (LED) enabled all the time but it flashes only when there is too dark. Sometimes when I am taking photo of some text LED doesn't flash although i think that flash would help cause when my hands are shaking the photo is little bit blurry. Is there a way to force phone to flash every time when LED flash is enabled?? (or there is just error in my device?)
Thanks in advance
upper left when phone in landscape more like a lightning icon toggle it...
I know that I have to toogle that in order to have flash. I was refering to different thing. The phone flashes (when the led flash is toggled) only when there is certaint amount of darkness. Sometimes I need flash although phone doesn't flash.

I have the exact same need.
I tried taking a picture of someone and there was snow in the background.
Result = camera thinks there is enough light so no camera flash and the person's face is in the shadow.
Does anybody know a solution to force the camera flash to go of while taking a picture?
what about trying other camera softwares?
I m using Vignette and I m satisfied... Maybe it can help you

Have you tried to close the ambient sensor with your hand? If you're on dark room it should automatically lid. but if you're on the bright room, it is of course turned off. there's an app on Market to monitor the ambient sensor. Play with your thumb above the sensor to see if it's working or not.

well, maybe reflash? dunno for another solution.. if it still persist, maybe you need to reflash with SEUS.. if it still like that, maybe you can ask to Sony Center i guess..

i cant find wat to do.. & due to water damage i think warranty also void..
no 1 to help frnds?
is there no 1 to help friends?
my keypad lights are working all are lid but only for few seconds may called it for 2 seconds that also when we unlock the phone either by slideout the keyboard or by pressing the unlock button...
i flash my fone 2-3 tyms by seus but no sollution...
is there any solution via changing drivers etc to enable keyboard lights only when we slideit out without the use of sensor or else..however my sensor is working
or any 1 please provide me there folder files of "sys/devices/platform/msm_pmic_misc_led.0/"
Hmm i don't know any other solution manjeet. But i want to share you the same experience like yours..
I have just reflashed into the normal firmware. but when i tried to test the light by closing the light sensor, i am surprised to know that the keyboard was not lid too! It just works for 1 second when i open the keyboard, and turns off soon. i was in panic then, but i tried to be calm, and when i tried to hide into a dark room, it works again. Fiuhh..
I don't know but maybe you need to really go to the dark places. Seems that the Proximity sensor and Light sensors work in tandem. If it still fails in the dark, then i guess you really need to have it serviced.. Dunno bout the cost, but it shouldn't be too expensive..
Good luck with your u20i bro.
thanx hansip......

Hi, I'm running neutrino rom and I'm trying to find a way for the notification LED to blink even if the screen is on. How can I accomplish this? I've tried lightflow but the LED still only blinks when the screen is off.
I would like this function, since if I have my phone in the dock and the screen has gone to screensaver mode I can't look in the satusbar to see if I have a notification. And since the LED only blinks if the screen is off I have to touch the screen to check and I find that silly to have to do. Sometimes I forget and then hours later I find out a have had missed calls and texts.

I believe our phone is one of those that doesn't blink led with screen on. I know lightflow warns of this as does my handcent. Don't think its possible unless someone else proves me wrong.
that's strange. if I mess with the LED notifaction settings under Cyanogenmod setting I can test the LED notification while the screen is on. Somehow it must be possible.

Is that cm7 or 9? I noticed in 7 the settings just aren't there (for me anyway) to use led for anything other than system default. With 9 I noticed led functions totally different like the charging led working (love that!) So maybe its rom dependent.
I'm running Neutrino CM7. the LED notifcationsettigns are definetly there. maybe it is rom dependant. Does the LED work for you if the screen in on running CM9?

I honestly haven't had a chance to test that with cm9. I load the rom and test the things that I use most in order, wifi, camera. I don't get passed the camera issue on most. That's a bug I can't live with since I take tons of pics. I will try to remember to test it out next time I flash. Im on rc1 of 7 now getting ready to update to rc2, maybe there will be something there. Where did you find the settings for it in neutrino?
Just upgraded to cm7.2 rc2 and found the screen on led setting. Works great for me. Just wish I could get a charging solid led that goes off at 100% I got spoiled from my flipside I guess but its just so much nicer to not have to turn the screen on to verify full charge. Lightflow didn't work for me.
THIS ISN'T YELLOW TINT
Hi, I noted that on my Xperia s there is the pixel resistance with yellow colors, in particular you can see it watching app titles in menu and changing page : you will see words not white, but yellow. Also with the notification bar, when you open it from the top of the screen also if you force shut down the last color that you see is yellow. You can see it in a lot or situation
Anyone knows why?
P.s I think it couldn't be fix by software update

have you done a software repair with the sony update service? if not then back up everything and start doing it.
Yes , i did this yesterday cause I tested cm9.0 (full internal memory wipe)
I've been using PA ROM for Galaxy S3 i9300 for a while now. So far didn't have any major problem except rare auto-restarts. But now I'm facing an issue with LED notifications. While the screen is off for any new notifications at the time of arrival the LED flashes once and that's it, then no pulsing. The notification settings are intact. What could be the problem?
Device GT-i9300
ROM: PA 4.45 for S3 STABLE
Same Here
I9300 with PA 4.45 (STABLE)
LEDs don't work 95% of the time. At first I thought either K9 Mail was a problem or a Gravity Box conflict. I did a second clean install (did not reinstall Gravity Box) but get same results. Regardless of which app. K9 Mail, Whatsapp, etc. Led flashes for a split second and that's it. Sometimes if I turn the display on and off it will start to blink.
Also did a test with Tasker>LED Notify, same results, flashes for a split second. After screen on and off blinks as it should.
Solutions or suggestions would be appreciated

Exactly same problem here. Any notifications like for missed call will work here because the screen is on when the the call is received and the screen goes off, then the led works perfectly fine. Tried also turning of the screen exactly when a generic notification is incoming. After screen off the led blinks as set. The problem is only when receiving something screen off. I don't know how android handles notifications, If known I can find the correct source of the problem.
You wrote:
"Tried also turning of the screen exactly when a generic notification is incoming"
I assume you meant screen ON. Actually I did a Tasker event for received notification with a Secure Settings tas of "wake device for 1 second". However a) it did not help the LED that way and b) it did not go off after a second.
I will be trying Light Manager as described here . Will advise if it helps but need to get back to work. Been spending too much time on this the last few days!

UPDATE: AcDisplay is working very nicely for me. LEDs work fine and its a neat app too!
