Are you sure it's a hardware issue (OK sound stupid but it's easiest to check if it's a software issue)? Try a couple of different ROMs, from the latest CM10.1 test builds all the way to rock hard stable CM7 and stock ROMs. It's interesting that soft key light is being changed though; did you mix up some wires or something? Also, not to insult your intelligence but you have turned off autobrightness, haven't you?

Sorry i forgot to mention those things... i already tried many roms, still the problem persist. and i dont think that i mixed up the wires cause it doesnt have much wire connections in the ribbon cable and they are just plug in type so we cant make wrong in the connections.
Even tried external apps to control the brightness... still the soft key ligh is adjusted not the screen brightness

in that thread you mentioned about increasing the brightness... what about the lowering the level?

i tried those codes...but nothing happened

I'm doubting it is software then, you have tried different ROMs and manually changing brightness so I will assume you need to replace your LCD. Being I have never seen this issue before this is just my best guess and what makes sense to me. It is doubtful that the flex is causing this issue and the screen itself is to blame

i dont think that the lcd is defective...i think my new ribbon cable is not supporting this,...but i dont know how and why?? (might be its because made in china?)
can i change the brightness level thru build. prop editor?

its very possible but it really doesnt make sense how the cable wont support it, do you have your old to test against?
and i doubt build.prop will change a thing as we have already attempted manually changing it and it appears to be hardware

yes am having the old one, but its fault is about the display..so cant use that any more... i tried to figure out the brightness option in build prop, but i cant find that option...can u help me on this?

truthfully i dont know of anything in build.prop that would be changed to change brightness level, ill dig around in a bit but nothing off the top of my head.
but again if using adb to change brightness or any other manual method wont change then there is a hardware fault somewhere as this happens across all roms.
i guess i never asked, is the screen the same brightness in recovery and bootloader?
if so you will need either a new lcd or flex cable

but in general even if we use low brightness in phone, while getting into recovery or bootmenu it will be in normal brightnes..i think so,....so i dont find any difference in brightness level at recovery page..but do we have options to change brightness level in recovery mode?

That would be coded into your recovery and bootloader respectively, I couldn't say how esay that would be to change, probably near impossible in hboot and still hard in recovery. Don't know the brigtness value in them but I assume high
I guess there is an off chance a sensor is malfunctioning, download z device test from market and test them, but this shouldn't be a symptom of a bad sensor.
Really you need to find out what hardware to change

unable to adjust brightness after replacing display

Hello,after replacing the display (by myself) , I' m not able to adjust the brightness of my display. It's stuck on the lowest level. Things I've tried;
- Called with HTC
- Performed hard reset
- Set the brightness to "auto"
- To adjust it with a brightness widget on my homescreen
- Replaced it with another display
- And of course digging through XDA
Specs;
- Desire Z 2.3.3,sense 2.1,unrooted
When I try to adjust it to the max.level it does not give an error. It just stays on the lowest level.
Is there anyone with the same problem or better,has a solution?
Many thanks in advance!
Can't adjust brightness either...kinda sucks
I am also having this issue and would appreciate any insight.
Did you guys do the work yourselves?
Yes,together with a video on "repair universe" I changed the display by myself (twice). Still having the same problem.
Anyone
Brightness stuck on highest setting
I also have this same problem. I just replaced the lcd display myself yesterday on my G2 with the help of the repair universe video. My display brightness is stuck on the highest level. When I try to adjust the brightness, only the buttons on the bottom of my screen (home, menu, back, search) change brightness but not the display.
I'm currently running ILWT CM7 297.
I'm going to try re-flashing my radio and then wiping and flashing a new ROM.
If anyone knows how to fix this please help!
I suspect it is hardware related such as the ribbon cable or screen is missing a lead for the dimming function. Can't tell from here though sorry.

I tend to second this opinion from killj0y.
Have you tried making sure the ribbon cables are tight and secure? Sounds like the ribbon cable from the screen may be loose.

Any updates
Has anyone figured out the answer to this? I just replaced the LCD from RepairsUniverse.com as well and the same thing. The brightness is low and won't change at all. Everything was fine before and RepairsUniverse.com says it's the motherboard. If the motherboard was fine before and all of us are having pretty much the same problem and some (or all?) of us got the replacement from RepairsUniverse.com, does anyone else smell a rat?
I know nothing of this company but depending on you screen problem, I wouldn't assume your mb is perfectly fine.

Has anyone fixed this problem? I have the exact symptoms, this is the second one I've tried, could it be because the lcd isnt oem? Please help
Hi. Are there any updates to this proble. I recently had the screen replaced on my Desire S and now it is stuck on the lowest brightness settings. Change any of the brightness controls does nothing. I took it back to the shop and they tried another screen, but still have the same problem. The motherboard was also replaced and the problem was there, but reversed...!? The screen was then stuck on full brightness...
Back to the original motherboard and the brightness is back stuck on lowest brightness setting....

[Q] cm9 buttons dont illuminate

I installed cm9 after using cm7 and cant get the four buttons on the phone to light up. They are accessible but not illuminated. has anyone else encountered this problem.
Also I was wondering if the Cm7 uses more battery than cm9
You have to use auto brightness.
cm9 illumination
If you mean display auto brightness ok but when I'm outside I can't see the screen...guess ibhave to toggle back and forth. I had switched back to cm7. In your opinion is 9 worth changing to. It seems like in 7 everything is working pretty well.
Thank you for the reply

Toggling auto brightness on and off solves it. Just tinker with it..

Ive been using the dinc2 since last July and I got used to the buttons to the point that I noticed they didn't light up, but until I saw this post, I never considered it a "problem". Since I knew where they were and didn't need to see them to use them. If they ever do "fix" this issue I hope they allow for a settings option to keep them turned off. I actually enjoy them off, in my mind its just one more security feature. I know when my wife tries to use my phone she needs to see them, and since recently rooting to CM9 I don't want her bricking my phone. Because of the unlit buttons she has stopped using my phone (she uses some cheap AT&T phone, refuses to switch to Verizon). Just throwing my opinion in the mix. Thanks for the post as well I wasn't sure it was intentional or not.

I believe in the advanced brightness settings under CMSettings you can do just that. Whenever I run a CM rom, I always go to the brightness settings under edit Other Levels and set all the softkey values on the far right column to 255 so they're always the same brightness and look nice. I like the sheen they have, but I can only see it when they're close to full brightness.
If you did the opposite, set all the values to 0 and then click Save and Apply Values at the top of that screen, they should, theoretically, never turn on.
Thank you ....as I am new to a rooted phone and this forum I didn't know those adjustments were available...learn something new everyday ......
Does cm9 drain the battery alot quicker or is it unnoticeable

Unfortunately, I can't answer that question for you, as my phone doesn't like our ICS builds. Until we get a leaked official kernel and some source, I'm SOL.

Where exactly are these settings? Running CM7 with the same problem as the OP and can't find it anywhere. Edit: found the settings and putting them all at 255 didn't do anything. Any other ideas?

Is backlight of touch input dynamic?

Hey all,
I experienced something a few mintues ago. I installed a new rom, Blissdroid. I 'discovered' that the backlight of the touch input (under the screen) was reacting dynamicly to sunlight. It went off in full sun. I couldn't find a setting to let it lighten up all the time.
I went back to Virtuous Unity, 2.35. It seems like the same thing is happening. I don't know if it's just normal (and I never discovered it before) or is there a setting I have to change (because I can't find one)?
Someone who can help me?
Thanks!

I tried that, didn't work.
For you it is always lighten up, even if you are outsise/inside where it is really bright? When I go outside, full sun, those 4 touch inputs will stop shine. It seems there is something wrong with my DHD? Or Am I mistaken? Someone who can confirm it is always lighten up?

Oh, so it is just a normal feature of DHD? Weird that I just discovered that yesterday
rcmix 4.0 and roms that use rctweaks have settings for this. alternatively you can set it to your exact preference if you edit framework-res according to this:
http://forum.xda-developers.com/showthread.php?t=1034743&highlight=systemui+apk
the link is manly aimed at tweaking your autobrightness, but it has info on butons too
Thank you. I only feared a problem, caused by changing ROM, as I never saw that before. I Thought those inputs were always lighten up, in every dark/bright situation.
depends on rom authors preference i suppose
if you are using sense 3.5 runnymede port, you can also flash tweaks as addon. some very nice features in there
Thank you all. I'm not great in flashing ROMs, certainly nog all those tweaks. I tried Virtuous Affinity and Blissdroid, but in both I heard a pop sound after playing music, sound, ringtone,... It seemed like I was not alone.
So I went back to Virtuous Unity 2.35, which doesn't give me any problem, except for a random bootloop from time to time (for example after playing Angry birds and once just after sending a message) what I can fix by replacing the battery. This happens 1 time in 3 months or so.
I just don't want to brick my phone, so I don't experiment much. Maybe one day, when I've got a new phone, I can use my DHD to experiment more.

Ambient Display Screen Flashes

Hi Guys!~
Hope all is well !!
... recently I came across my rooted android 11 Pixel 3XL got a screen flashes with bright home screen background during the screen turning off and entering ambient display mode.
I try my best to find a solution but haven't found one yet.
I have tried to reflash to stock, also doesn't fix the problems.
... the only solution I found at this moment is to get android 12 beta which the transition animation from turning off the screen to the wake up of ambient display is totally different and I still prefer to stay with rooted android 11.

Sounds like a hardware failure, display or mobo.

If you tried multiple roms especially the stock* one unless it's something you loaded after the flash, it's got to be hardware related. It's possible the non stock rom blew out some hardware too.
Try setting brightness to manual.
A rework around may be the only viable solution.
You ever wonder what happens when one or two of the billions of semiconductor junctions/resistors/caps fails in the chipset or display? You might be looking at an example
It could be a loose connection, or a faulty ribbon cable/connector, a subassembly maybe even battery (if so there be more symptoms).
*unless a known issue in this device.

Screen unresponsive for a minute after unlocking

Any time the screen turns off and I turn it back on, I have to wait 30 seconds to a minute before the touch screen is responsive at all. I've tried using my fingerprint or removing all screen security and that doesn't seem to make a difference. Has anyone else run into a similar issue? Any idea on how to fix it?

What android version are you running? Do you have many apps installed? Have you tried restoring back to factory defaults?
I believe it started after upgrading to 9 manually a few weeks ago. But I've tried a few different ROMs with the same situation. I have not rolled back to 8 to test that yet. It happens right out of the gate without installing any additional apps as well. I've done multiple full wipes, including unlocking the bootloader that for sure wiped everything with no change to the situation.

Any further ideas? Or is there a better location to get the RETAIL image for XT1710-01?

Actually, yes. Just after getting the phone, it was dropped and the screen had to be replaced. The fingerprint sensor has been loose ever since then too. But this was never an issue until flashing a new ROM

did you have someone else replace your screen? If so, and it might sound weird, they might have installed an LCD screen instead of OLED; and then modified the stock rom for that. You might not know, but OLED and LCD have very different power profiles, so when turning LCD on you can just blast it, meanwhile oled you need to slowly bring the power up. This is what might be causing your issues

You would need to remove the screen. Otherwise you can use something like AOD and check if the whole display lights up vs only the clock or whatever. On an LCD screen the whole display will light up a tiny bit vs complete black on OLED.
You would need to modifiy the dtb's and kernel, but it's something i would be able to do for you

I don't know if it's the reflection, but is there some bleed around the clock? Like is the dark areas lighter compared to the rest of the screen?

I think it's just the reflection? Here's a shot of my Nexus 6p right beside it and I think they look basically the same.
The phone is used almost exclusively for kids videos so it's not the end of the world if I never get it fixed, but at the same time, it would alleviate some frustration when I'm helping my daughter turn a show on.

Ok, I'm willing to try modifying the ROM if that'll get rid of the stupid touch screen delay. How difficult is it? I know you said you would be willing to do it for me, but if it's not something that will persist through an update (I had been running AICP) and it's something that I could learn to do, all the better. If that's not realistic, that's fine as well.

Introduction Hello everyone, I will be going over how to compile a kernel from beginning to end! Prerequisites: A Linux environment (preferably 64-bit) Knowledge of how to navigate the command line Common sense A learning spirit, there will be...
forum.xda-developers.com
Is a great guide, you'd need to follow the clang guide tho, as our kernel IS clang-compiled, and i recommend repacking the boot.img
You'd need to change this line
kernel_motorola_msm8953/msm8953-albus.dtsi at 7befedacd91b84ed737b691671c088c89e394f66 ยท AICP/kernel_motorola_msm8953

In your source to be
qpnp,qpnp-labibb-mode = "lcd";
If i'm right, after doing that and flashing it the issue will be fixed. Otherwise when you try to turn on the display it will cause a kernel panic
You would need to reflash this boot.img after every update, and redownload sources everytime i do something to kernel.
