It appears that there is a general issue with the G-Sensor after a screen replacement has been done. There are tons of users in the Android Q&A forum with the issue. The sensor works fine in winmo but not in ANY android rom after the screen has been replaced. I'm guessing its a hardware driver issue?
Please could someone tell us what info/data we can give to the ROM chefs and kernel gods so that they can take a look and fix this.

I have this same problem with one of my HD2's that had the screen replaced.. Everything works perfectly except the "G-Sensor"...
I posted the problem in this thread http://forum.xda-developers.com/showthread.php?t=902129 a while ago, and been watching ever since... Havent seen any solutions, but more reports of the same problem been added to it daily... I'm also assuming that they changed the G-Sensor hardware along with the screen... Beacause it works perfectly in WinMo, and it dont in none of the Android Builds I've tried (CMYLXGOs all versions, Imilka's all versions, RAFDROID, CyanogenMod, etc)...
Everything works good on my Primary HD2, no problems at all... I'm hoping some Chef/Kernel developer might just take some time to check this out...
Have you guys went into Settings>Display>and ticked the check box for Auto-rotate screen?

That option is checked by default.. Even if You uncheck and check it, it still dont work... If You go into G-Sensor Calibration, the bubbles dont move at all... All those solution was posted in the thread, in the link above...
I'm really assuming is some hardware/driver problem... It worked fine with android, but after they replace the screen, it stopped working...

Sorry I did not click on the link and rad the other thread. If you go to calibriate your G-Sensor and it does not move then it sounds like either your internal G-Sensor hardware is faulty or not properly connected. I would make the tech you had work on your HD2 work on it again or take it to another repair shop.

It's a good point You have there... But I would be assuming that was the problem if the G-Sensor wasnt working in Windows Mobile... Everything works perfectly in WinMo, including the calibration... Thats another reason we have come to believe its a hardware upgrade or something similar...
I have the same problem. I bought an HD2 from someone in the Marketplace, and I can see from the pry marks on the bezel and the broken adhesive that the screen had been replaced at one point. I also believe there must have been some hardware revision that is still compatible with WinMo, as the same driver works unilaterally, but not with Android. Definitely tried most of the recent ROMs and different combinations of kernels, and cLK/MAGLDR, but it never works.
Charnsingh alludes to the G-Sensor code in the kernel in his [DEV] thread here: http://forum.xda-developers.com/showthread.php?t=1049170 (don't post unless you're a dev though), and says that it's pretty minimalistic. So maybe there's a solution out there, but the developers haven't gotten to the bottom of it. I'm watching that thread intently to see if there's anything cooking or if there's something I can help with.
I think there are quite a few users who are suffering from this.
If the devs need anything they have plenty of people to ask for debug info, etc.
I just wish someone had the time to have a look at this
have got the same issue, new screen, sensors stopped working, all the sensors that is, light, proximity, g-sensor, compass. and everything works in winmo (except the compass, don't know why) the interesting thing is, the proximity sensor does work, it just doesn't turn off the screen, but it does turn off the touch screen, and the g-sensor actually seems to work, i can calibrate, and the relevant files are updated (in /data/misc the bma150_usr and the akmd files are created and/or updated) and if i move during calibration, it is aborted. it seems as if there is something broken in software because the chip data is still being read and used somehow, just not piped to the right places...
Every sensor work fine here with except the g sensor
I guess its a kernel issue and not hardware relates
it work perfectly on wm6.5,but not work on any andriod rom.
i have the same issue
so no one is helping us???
i have the same issue too...
Same here works fine in windows but android will not work.
Also have screen replacement
SOLVED
my issue is solved now after motherboard replacement.
a few notes:
- as i eventually discovered, there was in fact a problem with the compass (aka the magnetic field sensor) which didn't work in any os. with this issue i had a good reason to send the phone back to the repair shop and they replaced the motherboard under warranty.
- i don't know what solved the issue, it's either [A] the working compass (which is somehow needed for auto-rotation to work - in android) or the new motherboard (which does not have compatibility issues with the new screen - in android).
so, please check wheather your compass is working or not.
if not, reflash to stock and send it back for a warranty repair.
I replaced the digitizer in my phone myself and the G-sensor works for me in Android.
LOOOOOOOOOOOOOOOOOOTS of threads and posts since 6 months and still nothing. About those sensors problems / screen replacements and still nothing... It's so sad, the HD2 is dying slowly. Lolz, let's keep the faith!!
+1 same problem...
Any solution???
Thx.
Same.
perfect on Windows.
not working, gyroscope, compass, screen rotation on any android.
no problem with proximity and light sensors.
I had tried screen rotations witout main flex (that holdss, vibration, camera, volume, wifi, buzzer)
And the sad point is I had replaced LCD-Digitizer together these are taken from a dead hd2. So my replaced LCD is 100% orijinal. I did not seperate chasis-button flex also.
Hi,
I own HTC HD2 and recently it stoped working and i had to send it to be repaired. They have changed the board because the CPU has malfunctioned. Since then accelrometer is not working in any rom. It only works in Windows. I could not find any answers except that the new board installed could be unsupported in android builds.
Any help is appreciated.

I also found out that several more users in Serbia have this issue. Anbody else? Plese help?
This is a Driver issues, maybe the new board has some different Component, but is not only the g-Sensor, the Magnetic Field and Orientation aren't Working, this kind of problem take to long time to be fixed, now that the developers are Focused on ICS. I'm thinking to sell my HD2 and Buy Another one.

Maybe it will work in ICS if only we had the patience to wait.
It is wery strange to use a phone that does not have any rotation whatsoever. You have to try and take a picture or to watch a klip that is stuck in portrait mode and want turn. I cant belive that no one has solved this yet. PLEASE HELP!
After my digitizer broke, I purchased a new LCD and digitizer combination. I've got it installed and the new LCD and digitizer seems to be working well enough, it's just the the digitizer doesn't seem to be calibrated properly.
My first question is how would I go about calibrating the digitizer? Is that even possible? My wife also has a Nexus 4 and I've search around her settings and couldn't find anything related to calibrating the touchscreen. I see various things on the web about special numbers to input into the dialer (*#0*# , *#2664#) to test the touchscreen, but those don't seem to work on my wife's Nexus 4.
The second, and more important question I have is when I go to calibrate the screen, how do I get to the calibration software opened on my Nexus 4 since the basically unusable digitizer? I've tried the Android Screencast thing and while it will mirror my phone display, it will not allow me to supply any input. My phone is rooted and I've tried a couple of suggestions from the web, but none of them seem to allow the software to proxy my input from my computer to the phone. I've installed Webkey on the phone through the Play Store, but it seems as though I have to start the software to get it to work. Is there anything I can install that will automatically install and start itself so that I can interact with the phone via my computer?
This whole screen replacement ordeal has been interesting and educational, but I'm ready for it to be over now. Thanks in advance for your help.
hey,
i've done several searches and cannot find any threads on a fault i'm having.
http://www.youtube.com/watch?v=RSL1-Bsy5pI
Vid of completely stock nexus 7 not rooted exhibiting ambient light sensor/backlight issue. Screen dims beyond point where screen is visible when auto brightness is used or level is adjusted below 40%
UPDATE 11/10/13
ASUS are a joke. Tried to have it repaired as a manufacturing fault. They weren't having it as 6 months out of warranty. And there's rubbish 3rd repair centre TRIAGE SERVICES LTD claimed it needed a new main board as it was a light sensor fault at the cost of £207.06 (i could buy the new 2013 nexus 7 cheaper). I told them where to go with that and asked for my tablet back which cost me £35.
I bought a replacement board and fitted using the amazing guides on IFIXIT.COM
And guess what? same issue
2 possibilities here either replacement board has exact same fault (unlikely) or fault is else where (LCD assembly)
There is no way i've found that you can calibrate the screen using the tablet, not sure about other methods
I may try a new screen
UPDATE
Spoke to TRIAGE SERVICES LTD again shortly after changing the board and after a lot of longwindedness they say they have a way of reseting the screen although it not guaranteed to work and will cost £50 if it does or £35 to return if it doesn't. (why they did not try this when they had the tab is beyond me). I'm relecutant to send to them as every search i've tried to reset the defualts on the light sensor show nothing.
Now i know on the samsung you can get into a hardware test mode by dialing *#0*# wanted to know if there was a similar mode on the nexus 7. At least that would let me confirm and reset the values for the light sensor.
also when shining the LED flash on the sensor at close range when on auto brightness the screen does auto brighten.
Can anyone help me diagnose this further other than just changing the screen? i knew there are a few people with this fault
UPDATE I have tested a few hardware tester apps on the tab and they all show the light sensor to be operational and responding very well to light changes.
I'm wondering if there is some kind of CMOS in the display assembly or failing that the display driver are fooked.
When android is updated are the drivers also?
Does factory reset include drivers also?
Will flashing the rom via fastboot reset the drivers?
any help is greatly appreciated
Hi there are any way to fix GSensor ?
Because thats the reason why screen rotation is not working in my case after bootloader unlock.
In calculator i write in ",1234+" a tap on gsensor test and the result is fail.
Thanks in advance
The accelerometer is built in to the logic board. Chances are slim of repairing it without a logic board swap/phone replacement. Contact ASUS for warranty repair if you're under warranty.
It could also be a custom ROM issue if you're using one.

That issue and couple other appears after unlocking bootloader (official app from asus) so I do not have warranty. I try on LineageOS and stock firmware but in both case GSensor is broken.
G sensor fail

You need to delete the file /persist/sensors/sns.reg using TWRP or a root-enabled file manager. I've had this problem a few times myself and deleting that file takes care of it.
