I have not had any issues with the capacitive buttons up until a few minutes ago, when suddenly the capacitive buttons ceased to illuminate except in extreme low light (I hear this is a common unresolved issue). The second change to 'suddenly' occur to the phone's behaviour is the following:
When the phone is turned off and the charger is attached, the red LED light displays as usual, but after a few seconds it turns off, and the capacitive buttons become illuminated. Has anyone else experienced this?
Running stock android ROM
Yes! It happen'd after I flashed the ElementalX 3.4 kernel. I thought it was a kernel bug, am I wrong? :S

Hello,
Have an unusual problem which is that I cant see the screen on my PDA2K even though the backlight is enabled and the brightness is set to maximum. This has been working fine and I havent installed any software recently. Is this a hardware problem or does someone have any other suggestions.
Holding on/off for 2-3 seconds does turn on/off the green and red buttons but the physical screen doesnt change. Same problem on battery or power
Any suggestions,
Problem was with a connection
Okay, Seems problem was a loose battery. Once I made the connection a little more snug, backlight came to life !!
Update: Problem still there, must be an intermittent wire thing, as sliding the keyboard up or pressing on the corner brings backlight to life. Guess I will be sending it in for repair !!
Hi,
I got a strange problem there. Installed the newest versions of Answerkeys Disabler and Advanced Config on Monday (had older version on my phone before) and newly installed Weekday.cab for Weekday display in Touchflo and the Call History Tab. After this I had issues with the background light twice. When I lock my phone it is set to shut off after a minute, but the hardware buttons lights and the phone dimmed light stayed on, and when I manually shut them off with the power button the hardware buttons lighted up again after about 5 seconds and after a minute the display also got back into dimmed background light, like when you press a button when the phone is locked and display's off. Only Soft Reset helps to eliminate this problem. Only program I could imagine causing this would be Answerkeys Disabler, but in previous versions i did not have this problem. Anyone have any suggestions?
Hi,
On my wife's Xperia, she dropped it, which obviously didn't help, but it seems to have made it work strangely.
a) Pressing the power button does not turn the screen off, it just makes the screen dark however, in a dark room you can see it's still lit up faintly, so it drains the battery as though it's on all the time.
b) The LEDs when charging do not come on, however it is charging properly
c) When booting, the screen does nothing until you pull out the keyboard, then it comes on fine.
Any ideas, mainly it's point a) which is causing the problems. I've got insurance, so I can get it replaced, just didn't want to go through the hassle if there was a solution out there anyone can think of. Could something have got corrupted which is meaning it's not turning off the screen properly, which a hard-reset would help?
Cheers
Hello!
I wonder if anyone had this issue. Yesterday suddenly the backlight of my XT894 started to act weirdly. When i pressed the unlock button, the screen would go very bright and then shut off after 2-3 seconds, but I still could swype the unlock screen and hear the unlock click, even with the dark screen. With a little bit of external light I could see the image was there, but the backlight of the screen was not on. I went on to the power shortcuts and disabled the Automatic brightness control, and as soon as I did that the display turned on, very dimly but it turned on. When I set the brightness control to maximum, it still is very low. If i set the brightness to minimum, its almost impossible to see anything. In display settings, the automatic brightness is unchecked and the brightness fader is set to maximum.
I started suspecting the light sensor, so I went ahead and downlaoded a sensor tester app, and the light sensor appeared to be reporting the light levels correctly - low readings in the dark, and much higher readings in direct light.
Is my phone backlight dying? Any idea if this might be due to defective mainboard, or the display itself?
I already did some repairing on the phone myself, so I am comfortable dissassembling it and changing parts. Few months ago I changed the main board because my old one had a broken usb connector, and it worked fine until now.
Any advice would be greatly appreciated!
Thank you in advance!
Best regards,
Konstantin
If I remember right, by default, the maximum auto-brightness is still lower than actual maximum, so if the screen can barely be seen at manual max, it makes sense that the screen is pretty much unviewable with auto on.
Idea:
If you have it installed, boot into Safestrap and see if your brightness is normal.
If not, pull up the diagnostic menu (hold Vol - while powering on iirc, might be Vol - and +).
If your brightness is normal in those, it's probably something gone wonky in Android. If not, your screen backlight might be going and needs replaced. I don't think there's anything on the mainboard that would cause it, aside from the circuitry actually supplying power to the backlight...
Screen replacement actually isn't terrible for the D4, if it comes to that, since it's not fused to the glass (like certain single-piece phones for example...*sideways glance at the S3*).
Hello!
Thank you for your reply!
Effectively something is very wrong with the device. Today I woke up to find it completely unresponsive, had to turn it off by holding the power button for a while. When it turned on again, the whole screen was white with glitchy color lines since the very reboot, and nothing else happens, couldnt even turn it off without unscrewing the battery.
I will put the old main board to see if the other one died.
Thank you again!
Best regards,
Konstantin
Hello there,
I got my hands on a M7, which was fully stock and working. It has some minor scratches and damaged material here and there, though it worked fine, except for phone calls only being audible in speaker mode.
I flashed TWRP recovery and installed the latest nightly of Cyanogen mod (cm-12.1-20151005-NIGHTLY-m7). Though to prevent the custom recovery from being patched I unlocked the bootloader (Not sure if that was the solution, though).
It was all fine, until the screen dimmed, and I tried powering on the screen again by pressing the power button. Though it wouldn't turn on. I even tried setting on the option to turn on screen when connected to a power source, though it never powered on again. I also noticed a slight flash of blue light every now and then, and the screen feels too sensitive. It might register a press when you're just scrolling.
Could someone help me out with this? Of course I believe a hardware fix would be appropriate, but as how everything worked until the flashes, I believe it might be fixed with some software.
Any help is much appreciated.

If you are talking about the screen not turning on (as opposed to the complete phone) Its a known bug of CM roms. The screen can't be turned back on when it was set to minimum brightness, or when the auto brightness set it to minimum. To avoid that, you'll need to adjust the brightness yourself instead of auto mode, avoiding the minimum adjustment. CM is known to be a buggy rom for the M7, you shouldn't have this issue if using a GPE or Sense rom.

Thanks for the info. I figured as much, I will try Exodus.
EDIT: I have tried Exodus, XenonHD and Dirty Unicorns. Though no success: none of them were able to turn on the display after it dimmed.
