H815 gyroscope fail - G4 Q&A, Help & Troubleshooting

Hi all,
I'm having a strange issue with my G4 H815, and I hope someone here can help!
The problem is that the phone won't rotate the screen when you rotate the device, and then the touch screen will not work. I must turn the screen off and then on again in order for the touch to work. But it will stop working as soon as I tilt the device (activate the gyroscope to rotate the screen). After some time this will force phone to restart and then it finds hard to boot up again.
I think it's gyroscope because the problem happens when I turn the device on the side for eg. when I open camera everything is OK but if I try to take a landscape photo it will immediately freeze. And I also did the testing procedure (277634#*#) when I test the motion sensor gyroscope values hardly change. Also in Settings>Display>Motion Sensor Calibration I get and error "Cannot Calibrate"
My questions are:
Where is gyroscope located?
Is it part of mb (soldered to the mother board)?
Does the screen digitizer affect gyroscope function? (because the glue on the top of my screen has come loose but I don't see it affecting anything other then proximity sensor).

Need help on disable proximity sensor TP2

Hi
how can i disable the proximity sensor on my HTC Touch Pro 2, windows mobile 6.1 ?
I use a screen lock app that dims the screen during calls but when coming near proximity sensor during call, the screen is turned on again - a real pain.
Please if any onw have an advice to shut it off cpmpletely or when i am on bluetooth i would be really happy for some help
PS i thought paroximitysensor was supposed to disable when tp2 is connected to bluetooth - but its not ??
thanks
Nolan
no one ?
regards nolan
having the exact same issue. I found a cab called TurnOffTheLight but haven't had a chance to try it yet.
For me, it would be better if the proximity sensor was off permanently, if possible.

Hi
could you test teh cab and tell us here if that can turn of permanemtly the proximity sensor ?
regards Nolan
TurnOffTheLight works to turn off the backlighting but as soon as you move the phone the proximity sensor kicks in again.
in the app called Advanced Config there is a category for adjusting the threshold of the Light Sensor. Unfortunately I have no idea how to adjust it (it is at 0 now) and/or if adjusting this would affect the proximity sensor. Can someone comment on this?

Proximity Sensor behavior and solution
I am a late comer to this bb! Hey,I thought all the bugs would be worked out by now! My keyboard did not work right, .... and I have had several other problems with the touchpro2. What are the Chinese doing over there? I had programmed many embedded units and microprocessor systems, but, really, how can they mass produce units like these? Too many cooks in the soup? They are leaving their quality control to the general community.
My problem was I use my gps for bicycling, and if I place it in the support case, the proximity sensor would shut off the screen, even though I was not placing a call. The screen would blank and not come back on. I noticed there was no problem if the physical keyboard was opened and also if the unit were held horizontally. It did this all the time, regardless of the app running.
There are two sensors at the top of the unit: proximity sensor and light sensor. This is a problem with the proximity sensor, at the left.
So I just placed duct tape over it. Now it does not blank.

Proximity sensor and phone

I've got a problem that when I phone my screen goes blank without waiting me to put it against my face and then doesn't come back on again without me having to push the power button.
Any ideas where to start looking. I'm using the standard stock 6.5 WWE ROM.
I believe it uses the ambient light sensor on the front of the device to determine when it is against your face. Make sure the sensor is clean and not hidden under an aftermarket case. The TP2 might also use the accelerometer to determine the orientation of the device, in order to complement the light sensor and better determine when you're holding it up against your face.
So I'd go into the settings and calibrate the G-Sensor as well.
Thanks will take a look at that.
Having an Issue with Proximity Sensor (Can only talk on phone with Keyboard extended)
I am having a proximity sensor issue with my Tilt 2. When the proximity sensor kicks in and the screen goes black, the person i am calling doesnt hear my voice. Only when I move the phone away from my ear or extend the keypad so the 'lights stay on' does the other person hear my voice.
What can i do to force the light to stay on even when its up to my face.
where is this sensor located on the front of the phone? I am wondering if my screen protector is causing it. I have no clue
Helo,
Same problem here.
Any help?

energy rom's bug?screen light off when calling

I flash energy's rom,it's good.but screen light off when calling makes me crazy.However I press the power button,the screen does not light on.every way i can do (regedit,change light sensor) does not work.
so please ,anybody knows?
You're saying that no matter what you do, the screen will not light up at all during a phone call once the proximity sensor turns turns the screen off?
yeah,you are right,but some rom can light up during a phone call,others can not.I'm crying for this
I've used Energy ROMS, and they were bullet proof, ran perfect, did everything they were supposed to do, like turn the screen off when I help the phone to my ear or had an object within proximity of the sensor, and the screen relit whenever I pulled the phone from my ear or moved an object away from the sensor...if you're saying the screen stays dark and you cant turn it on even with nothing blocking the sensor, then I recommend posting that issue in the Energy ROM thread as there could be a solution...if you're saying the proximity sensor works normally and you'd prefer to deactivate it, I searched around for that for you and didn't find a resolution...you can, however, if the sensor works properly...cover it up all the time (perhaps a small piece of black tape or something)...you'll have to hit the power button one time each time the phone takes or makes a call but the screen will stay lit til you turn it off again, even during a call
thank you Gt247. thank you so much.I think I found the way to resolve my screen's problem
I read a bunch where people were looking for a way to disable the proximity sensor...perhaps if that's what you've done, you could post the solution here in the event those peple are still looking
I have tried some apps to disabled my proximity sensor,but those all do not work,I think it's my phone's hardware problem,I have already decided to open my phone to fix it.
so before I fix this fool sensor ,any knows which app can test the proximity sensor?
just a app to test whether my proximity sensor work normally, any clue?

You don't need any app to test the proximity sensor , just turn on your screen , and cover the sensor with your finger . If your proximity sensor works normally , screen will be off . When you remove your finger in seconds , the screen will be turned on again .
I think you can disable the proximity sensor simply by removing the shortcut in the "startup" folder , and restart .
If I misunderstood your words , ignore me pls ~
thanks pcgg.I have tested my proximity sensor,it seems not notice my finger,the screen always on.
I have not found the proximity sensor shortcut in my startup folder,here is the file list in my startup folder:
DeviceLockXT.lnk
LockDevice.lnk
SpbMobileShell.lnk
so could you tell me which lnk is the proximity sensor?I can't find the file about what you say by the name
It seems that there is not priximity sensor app in your phone ....
While there is an app called "Rhodium setting tool" in mine , and it has a option under the menu "phone" named "Light Sensor" . If I turn it on , screen will auto turn off during a call .
Maybe you can try that ?
Well , I must say that I did misunderstood your words ... I thought you were complaining an app called "Proximity Sensor" . I found it in the "Jackos" ROM ... Sorry for misleading you .
You can try that app "Rhodium setting tool" . If it can not work , I will have no idea about it .
thanks pcgg.
I have already try the light sensor,I have tried many apps those can control the light sensor,but those don't work at all,at last I get a conclusion that is proximity sensor has a higher priority than the light sensor,proximity sensor can decide whether the screen can turn itself on or off.
my rom now is seeM_ZA's simplicity rom 21916,I'm now ready to flash jackos'r rom.whether it works ,I will tell you the result later
Any of the two, i suspect the first:
- you probably have some dirt inside your phone, at top left corner where the digitizer has a semi transparent glass for the proximity sensor (you hardly see it without disassembling screen)
- the proximity sensor is KO, you have to replace flex to cure it (about 35$ on eBay)
Once i replaced the digitizer on a TP2 and a little drop of glue went near the window of proximity sensor, it didn't work at all till i disassembled all again, cleared the the glue around the window letting again enough light to enter the sensor.

[Q] auto rotation when sliding down the screen

Hello
i have an issue that makes my screen is not rotating when i slide down the screen.
It seems that the hardware screen closed detection is not responding.
my problem is that i have totaly disassembly my tp2 in order to change some parts.
After cleening all the electronics part i h'ave re-assembly every things. Now it's working fine exepted this issue.
The screen is keeping the landscape mode without possibility to change it.
Do you have any idea ?
Does any body know how the screen closed sensor works ? An where it is ?
any picture ?
my problem is exactly the same as
http://forum.xda-developers.com/showthread.php?t=1282596
It's a magnetic sensor, but I don't know much more about it.
iFixIt might help you.

Proximity Sensor Broken - Nokia XL

Hello!
I've started to have a problem with proximity sensor. While calling, the screen get black and there is no way to turn it on (it turn if the other persone close the call only).
I tried to install a proximity sensor controller utility and it says it's always 0cm distance. By touching it I found it unlocks sometimes under pression or temporarily if I blow in it (but after a little it locks again).
I searched in settings an options to deactivate it but I really can't find it..
Can you tell me where I can find the option to turn off the proximity sensor, please?
And is there any way to fix this problem eventually? However I'd be happy if I can just deactivate the sensor..
Thanks
