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!

ive been searching solution to this problem for almost 6 months now, still to no avail.

G-Sensor and call problems

Well first of all I love Android, but I have some problems. The first problem I have is the G-Sensor, it used to work, but suddenly it stopped working properly. Now when I want to rotate the screen I have to hold it the way I want it to turn for 20 seconds, is there a solution to this problem?
Now my second and most important problem is calling. I have multiple problems with it. One of them is when I'm being called while the phone is in lockscreen I try answering it but I have to wait ten seconds before it actually answers, mostly the caller is already connected to my voicemail. My second problem is the End Call button when is press it, it says ended but I also have to wait ten seconds before it actually ends the call. Does anyone have the solution to these problems?
For further information, I use Froyostone 3.2. And sorry for my poor English.

Could anyone please help me, sorry for the bump?
Also I notice that my hardware buttons light up randomly.

I also have the same problem. Well at least with the g sensor. Running android 2.2 the problem with my g senor is whenever I flip messages they will not flip back. (along with anything else that does flip) I've done the re-calibration on the phone and this is what happens.. x axis is fine y axis either stays all the way up or goes all the way down. When I start the calibration the y and x axis both go to the middle but after when calibration is done the y axis goes right back up or right back down.
Thanks in advance if any one can help.

The same thing happens to me when I'm trying to calibrate it. Also have you tried holding your device for 10-20 seconds the way you want to turn it? This solves the problem for me, but I would like it to happen a little faster.

I calibrated the G-sensor when I first put on Android, bad mistake, the Bubble just stayed at the top and nothing rotated properly. The Sensor worked fine in WinMo so I guessed I'd screwed it up.
Since read somewhere on here that you shouldn't Calibrate it in Android.
Had to reinstall Android fresh to get it to work again, but its been working fine since.
Was on froyostone 3.1, when I reinstated upgraded to 3.2, all is great

Okay that could be the solution. Do you also know if I need to put a new data image on it. I would like to keep my old one, but I thinks the problem lies there or doesn't it?

You might be able to calibrate your G-sensor in Android. Click the calibrate button and place your phone screen down on a flat surface. For some reason, calibrating only seems to be working when you face your phone screen down. It did the trick for me, fixed the offset and it's working just fine now.

I tried changing the data image from 3.1 to 3.2 but the g-sensor was the same, i just used Titanium Pro to backup the data i wanted to keep and reinstalled.
Try the Phone on its screen re-calibrate as suggested, ive read that may work as Roeltjuh suggested, but that was after i had reinstalled

That seem to do the trick, thank you!
Does anyone have the solution to my other problems? Also I've noticed a new problem, sometimes my WiFi won't turn on till I reboot. In the settings menu it says shutting down WiFi. But its already been shut down, and because of the loading it takes to shut down wifi, I can't turn it back on and my data connection says that it will be turned on when my WiFi is shut down. So I always have to reboot.
Sorry for all the questions, but I believe some of them can be fixed and they're too annoying to ignore. And again sorry for my poor English.

[Q] Notification LED

Hi People. Firstly I want to say a big "Thank You" to this board. Because of this place I have Android running very stably on my HD2.
Now to my question...
When I stick a new build on my SD card, the notification LED seems to work fine when I have just installed the build, but after a reboot the LED kinda goes wierd. It's like it wants to work, but isn't quite. i.e. If I lock the screen I see the LED blink once, then it stops. Then if I power up the scree again I get another blink.
But I know it does work fine straight after a build gets initially installed.
Anyone got any ideas what might be able to fix that?
(Using VBNDroid WM ROM, JDMS Stock PPP Android ROM, MDJ S4 Kernel)

I had the same problem, but have found a reliable (but not practical) way around it. I found that if on each reboot I have my phone connected to a charger or computer USB, the LED's will work fine. If not, then sometimes they will and sometimes not. I have tested this over the past four days with consistent results. If anyone can try it and comment it will be appreciated.
Thanks

Ah.... Interesting.
I kinda noticed the same thing, but wasn't sure if I was just imagining it or not!
So when you power on your phone, you just have it connected to power? Then once you disconnect your notification LED still works yeah?

Exactly!

I've just tried this, and it seems to work.
Powered down my phone with Notification LED not working correctly. Plugged in the power, booted up, unplugged power = notification LED now seems to be working.
I'll do some more testing too, but so far so good.

well...i did the same thing..works but..i have one problem!the led blinks ok for each notification missed call or receiving message..but it blinks only once and then dissapears..is there any point so i can make it work like in windows mobile where there it blinks every 4 seconds????thanks..

Or, the notification light gets 'stuck' on, and isn't consistent? I.e. works OK for a moment, text message gives a flashing red... then green gets stuck on? Then I get another text and red gets stuck on?
Notification misbehaviour!

Random charging issues

So my phone has started having random issues. Running stock rooted 4.3 and have only flashed an LTE enabler.
This morning I received a text, but when I tried to read it, I got an error that messaging had stopped. I hit okay, error came back when I tried to read the message again, it did this several times before I rebooted the phone with quick boot. A little later in the day, same problem with maps. Then I made a phone call and when I hung up, the system ui stopped. Had to power down phone.
I also noticed last night while trying to charge it in my car, it didn't seem too be connected. The charging text on the lock screen was like flickering. I thought it was the charging cable or USB lighter adapter. Grabbed a charger and appeared to be working, but was noticing the same problem with the charger.
Anyone heard of this before? Are they related? Haven't download anything recently, but maybe something updates? Not sure what direction to go to try too fix.

I have this same issue and mine happens sometimes while its charging I found out. Basically all the Google apps stop working including settings now I can access any other app just not the Google apps. The only fix is to reboot the phone. I wish my phone was still rooted so I could use logcat and hopefully catch whatever is causing this.

Have you tried different roms?

Nope, stock ROM 4.3

Bump?

Haven't had the issue with any apps closing. But it still don't charge with my car chargers. I briefly tried with a charger at home, but didn't notice the issue.

That's what mine started doing right before I got the flashing red LED of death. Sent it back for a refurb.

[Q] Blinking Red LED Notification

Hi,
I tried to change my file system from Dalvik to ART and when my phone was optimizing apps after reboot, my phone suddenly shut off and it wouldn't turn on. If I try to turn it on, it will show a solid red LED for 3 seconds or so and then start showing a blinking red LED.
I did manage to get into the bootloader and I flashed the whole factory image for Kitkat and erased my data through fastboot, but it didn't fix anything. Anyone know if there's anything else I can do? My phone is outside warranty because I bought it on release date last year :/

Look what this guy had: http://forum.xda-developers.com/showthread.php?p=47968382
Spoiler: it's the exact same issue, and he resolved it. Wouldn't it have been great if you just searched the forums for a similar thread before posting this? I can answer that. Yes, yes it would have been great. It would have saved you time waiting for an answer here. And it would have saved me time writing this rant. So next time, use search.

Oh thank you. What great luck that he had the same problem. Does anyone actually know why disconnecting the battery cable would solve the problem? It seems odd that this is caused by a software problem, but a physical fix returned it back to normal.

Problem solved, so i suppose we can close this thread now
