Flash LED randomly turns on to random brightness level

I just got a Tmobile MDA today and it's a cool little device. However, the LED Flash is randomly turning itself on, does not randomly turn itself off, and the weird thing is that it doesn't always stay on at full brightness. I have found that if I manually toggle the flash in the camera app, it turns off the flash for a time.
Also it tries to light up kinda like the way a fluorescent bulb lights up, flickering and only going full blast if I turn it on.
I have checked the wiki, and the first three pages of the forum, and google, and no mention of this problem. Any ideas or maybe a fix that I missed??
Thanks!

Hi
Glad to know I am not the only one with this problem!
Mine started to happen about a year ago, exact same symptoms as you describe. I have not managed to find a fix and can tell you it is defo not software related.
O2 Xda Mini S is the model I have for your ref, O2 are of course saying it needs to be sent back under warranty.
If you do ever find a fix post a reply as I would be interested to know what it is!

[Q] Defy MB525 constant blue led

Hi,
I need some advice. I bought a Derfy a couple of weeks ago, everything is fine, except the notification led. It lights up blue right when I insert the battaery, and remains active, no matter what I do. If I get a notification, it flashes purple-blue.
I checked the indicator, it seems that no water reached the phone. I cannot find a hardware issue.
Does anyone have an idea, what this thing should be? Not a big problem, but it's irritating.

do You have stock rom or not?

I use stock software now, but tried with many custom builds, the blue led stayed.

[Q] Black screen issue.

Hi there.
First of all i'm from Denmark, so sorry for my english.
I have a Oppo find 5 with CM 11 ( Cyanogenmod )
The other day when i took it out of my pocket to check on it, the screen dosen't turn on when i unlock it with the power button.
The onscreen button's starts to light, but the screen keeps black for 5-10 minutes, then it randomly turns on by it self..
I have made a hard reset, tried a different ROM but nothing seems to help.
Is there any of you in here that can help me, or knows what the problem could be ?

Have you tried stock rom? It could also be hardware failure.

Hi,
It's an known bug in cm11, but maybe it's fixed in latest nightlies. Better read on the oppoforums since there is more activity about this.
Sent from my X909 using xda app-developers app

I had this bug also just keep cm11 up to date! and if it happen push the powerbutton untill you see the oppo logo on your screen

You can try but i don't think it's gonna work. As you describe it it reminds me of the sony xperia ray st18i i once had. It had the same problem. I had to cool it down in order to work. Try playing a game or 2 with battery mode to normal to see if you reproduce the problem. Also if the problem occurs call your phone to see if it's still on
And try these steps http://recomhub.com/blog/how-to-fix-huawei-p9-black-screen/

When black screen occures, phone is on, but it does not ring. Black screen comes when long time 1h or 2 phone is on idle and unlock - it turns on display and freezes . It makes that randomly... .

so the background lights up but nothing shows?
i think that the best thing you could do is ask huawei themself what the problem is.
(don't tell them you've got root and stuff like that.)
also try to upload screenshots from your developer settings in here.

the screen is flikering

hi guys, need help with following:
sometimes the screen flickers and stop responding overal....when he is in the mood. Sometimes works 2-3 hours with no problem and sometimes I cant use it at all - display is flickering and stop responding and if I lock the screen with power button and push the button again the screen is unfreezing for a while. I have tried everything- reinstal oficial ROM, root the phone and instal some custom ROMs, custom recovery, wipe and clean everything nothing helps. Мy suspicions are that there is some hardware problem and there is no software solution, but if someone has faced such troubles and find a way to resolve them pls share

it probably is a hardware issue, most likely the adreno GPU failing. Youve flashed the tar.md5 stock firmware and its still doing it? If so, its very likely a hardware issue

yep, I've flashed the original tar, also tried with 4 file with pit. Some time the phone starts flickers on the Samsung logo at the beginning, some time passes the logo and initial setup and then starts....maybe your are right, I just love my phone and didn't want to RIP him. The only thing I didn't try is to install something different than Marshmallow and to decrease working frequencies. Can you please tell me if the problem is form GPU is it worth to be fixed?

you could try a new battery , my S3 had screen flickering problems at aprox 30% battery and then freezes and reboot and battery after reboot suddenly 2% and after that screen flicker and no power anymore.
Try reboot with only charger connected and no battery connected

can't do that - the phone cannot be started without battery inside. Furthermore the battery is brand new original and I start using it after the problems started

You can look with phone info app from play store. Look which date the phone was made and when its more then 2 years then its hardware issue. On my display its only flickering on the very lowest brightness levels when i make it brighter the flickering is gone. When your phone is so too then its hardware issue but i will look with another battery from a friend and will report. I think its the display like plasma 1-2 years burn-in.

I had the same problem with screen flickering with my s5 (QCOM variant). It had started after screen replacement in a repair point. It would get the worst when screen brightess was at the minimum level. Sometimes the screen would not wake up, and low temperature/ low battery level made it even worse. The answer to the problem is a defective screen which needs replacing. No other way as far as I know.

the screen is flickering

I have the Samsung Galaxy S5. I also had the issue of when I had the screen brightness on auto it would flicker or if it was on a low setting it would do the same. If I raised the brightness it would stop. When the battery goes below 8% it starts flickering non-stop and the only way to stop it is to plug it in to an outlet. I took it to Verizon about 6 months ago (about the 2 1/2 year mark when it had been doing it since around 2 years) - of course their immediate answer was to do a factory reset and after that they had no solution (I did NOT do a factory reset). I'm eager to hear if a new battery corrects it or if it is indeed the screen/display. This may be a way to make sure we get a new phone every two years...

my case looks different. The flickering not depend form brightens or remaining charge in battery. Furthermore sometime it stops at all and I can use the phone without any problems for 1 or 2 hours. I did factory reset several time and reinstall software (official and custom). Perhaps there is some hardware issue and a phone upgrade is upcoming.

I tested with a battery from a friend yesterday and its the same. I will do this week a odin stock flash day and then i will see. But i think its the display.
