accelerometer calibration?

Posted a few other places with no answer...
Is there a way to calibrate the accelerometer? Mine is WAY off.
My friend has the HTC Incredible and he can do a quick accelerometer calibration by placing his phone on a flat level surface and hitting a calibrate button.

there's a game called "papijump". it let's you calibrate your accelerometer. works great.
cheers

Great app for calibration is Advanced Bubble Level. You can calibrate the accelerometer on all sides. You just need level surface.
Sent from my GT-I9000 using XDA App

The problem about Advanced Bubble Level or any bubble app, it only calibrates the app your using, and doesnt calibrate the system accelerometer, therefore when using another app that doesnt give the option for calibration such as the game ASPHALT 5, you'll end up being stuck again, with no way of calibrating the accelerometer.

I've contacted Samsung regarding this and they told me to go to the service centre as this is a hardware issue. If it is possible to correct it on site (which they told me is very unlikely) they will do so, if not, they will send the phone back to Samsung so it can repaired/exanched.

there is a script you run to calibrate search on this forum

Also, in JP3 firmware, there's calibration in the Settings, so it's obviously coming with Froyo.

My Galaxy S acts like its accelerometer is not calibrated. However, I checked with the internal hardware test. Dialed *#0*# then entered Sensors dialog, and my readings on x y z axis' went to 0 when put on a level surface. In spite of that, Layar and Asphalt5 still thinks my phone rolls to the left when on a level surface. Pretty strange.
It is very frustrating, that Samsung lacks the calibration feature. I think I will return my phone, not because the hardware is broken, but the soft(firm?)ware surely is.

My Layar rolls slightly as well but that must be a software problem. I'm sure there will be a fix with FroYo or something. My Asphalt5 plays fine though.

This has been discussed extensively before... it is fixable only through root. You just need to run the sensorcalibutil_yamaha tool, which is in /system/bin .
Here is the thread: http://forum.xda-developers.com/showthread.php?t=712439
Layar and everything else is completely "cured" doing this. As it was said, there is a problem with factory calibration.

Correction: hardware test has so low resolution, that it displays zero in a wide angle.

SOLVED!
Before launching the
Code:
su
/system/bin/sensorcalibutil_yamaha
from the terminal:
try this http://forum.xda-developers.com/showpost.php?p=9876929&postcount=42
Then do the calibration.
DONE!!

Or in 2.2..
Menu -> Settings -> Screen -> Horizontal calibration. Hey presto, it's calibrated!
(I've translated the labels here, so it might be a bit off )

Does the menu->settings->display->horizontal calibration appear in all 2.2+ phones, or is it SGS-specific?
If I'm writing an app that measures the phone's pitch, should I include my own calibration option?
PS: Hi! First post.

dude i wanna kiss you, i really do lol
i had a problem with the accelerometer for two days, i tried everything to fix it but i couldn't, until i read your post, so i placed the phone on a flat level surface and hit the calibrate button and it worked like a charm!!!!
thanks a lot man

Guy's,
The accelerometer on my rooted 2.2 suddenly stopped working. It was working fine one moment then the next it just stopped. I've tried it in several applications including the Bubble app and everything just displays in portrait. If I try to play a game which uses the accelerometer it either fails to launch at all (Asphalt5 tries to launch, vibrates a few times then shuts down) or it just doesn't play e.g. in Labyrinth Lite the ball just stays put regardless of how I move the phone.
I've been into settings -> Display -> Auto-rotate screen to make sure that's ticked and it is and I've also performed a Horizontal Calibration in the same menu with confirmation that the phone has been "Calibrated". I also did several battery pulls without success.
Seriously confused.com here.
Any ideas?

Calibrate accelerometer and/or gyroscope

Hi!
I am facing problems with the orientation sensors (accelerometer and/or gyroscope), because installing several applications to test them (or use games), it is clearly observable, that they are a bit off (with enough to be disturbing when required). For example, games or tests that simulate a ball, and my phone is laying on a horizontal table, the ball rolls quickly to the edge of screen. This happens as well with the built-in tests in the "service menu" of the phone, for accelerometer and gyroscope also.
Do you have any suggestions how could I calibrate these sensors globally (for every app)?
Thanks.

factory Reset ur phone and then use PC companion app to Repair Firmware...
this can wipe current data and install fresh firmware on ur device
:good:

Hi,
I have the same problem. Only the x axis of the accelerometer seems to be affected : it show a value around 1 instead of 0 while the phone is sitting flat. Y and Z display normal values.
All the software solutions I have tried have had no effect at all... It seems the built-in test reads raw data from the accelerometer. It is hard to imagine how this can be a hardware problem though...
Anyway, in my case I believe a software fix (x=x-1) would do the trick but I have no idea how to do such a thing ! Any help ?
@vekto : Have you solved the issue by any chance ?

Would anyone care to try the accelerometer tests and post their results ?
Typing *#*#7378423#*#* will get you on the service menu. The two significant tests are "accelerometer" and "gyroscope".
I'd post some screenshots myself but I'm not allowed yet...

I'm having the same problem now. It seems one axis is affected. Haven't found a way around so far. This is sad because it affects the images taken with Google Camera Sphere mode. The images are badly aligned together with glitches in between. My phone wasn't like this before.

Either a SW fault - might be able to calibrate with GPS Status & Toolbox app, for example - or a FW fault - and reflashing ROM might help (highly unlikely) - or HW fault - the sensor has moved on the board (which is a bad sign anyway, might be on the way to disconnecting itself).

I sent mine to Xperia Care and got it back with the accelerator fixed. Still unclear if it's a HW problem...
It came back with a white spot on the screen (near the power button) though... so I sent it back again

I'm also having issues with the gyroscope. Installed Bubble app to calibrate the gyro. It showed the gyro was of a couple of degrees. Unfortunately the bubble app calibration doesn't work in a game like Need for Speed. It's very difiicult to achieve good times in the game right now since I have to hold it tilted to the left to go straight ahead.
So if anyone has a fix or workaround... Please do post.

Same problem, Seems after factory reset whith wipe dalvik cache.

any solution?

02nd March 2017, my autorotate has completely stopped working, restart, safe-deposit and reset do not fix. Diagnostics show Gyroscope Light Sensor and accelerometer failed testing, 3 years of same issue, surely there must be a fix that works by now?? ( please note, " turning it off and on again " does not fix it )
Helps Please

I have the same issue. Since last week, gyro, accelerometer, light and proximity sensors stop working. I've tried reflashing stock ROM without success. I have not warranty (almost 3 years old), so I even try to disassemble , disconnect an reconnect every flex (I don't know exactly were the sensors are located on the board). After that I get almost 8 hours of fully functionally sensors and then, they stop working again, so I'm almost sure it's a hardware issue.

Same problem for 3 years
I'm just now getting around to doing something about this. As my power button stopped working I can't post requested screenshot without going to the pc. I have been shopping new (fall 2018) phones after having the Z3+ since release. In my research I'm finding the phone still is better than Samsung, LG, and the pixel3 for me because the 3.5mm phone jack is mandatory for me using my device with an i-rig midi requiring both that port and the USB at the same time. I'm going to do everything I can to keep using this phone till it falls to dust. It's one of 4 Sony I've bought since the day Z1 came out of t-mo. I look forward to testing solutions. :good:

Some time after my post, I bought a new jack/proximity sensor flex and replace it. This solved the issue, but weeks later, the bottom portion of the touch screen becomes unresponsive. May be I have done something wrong... may be programmed obsolescence...

Hi I'm facing a problem of my gyroscope I don't know which one is not working a gyroscope or accelerometer. My gyroscope is so delay when I play pubg mobile and I can't also calibrate my Gsensor it always says FAIL but I put in a perfect flat surface please please please help me with this problems

Rear camera-hardware detected, yet black image. Camera "bus" malfunctioning?

Rear camera-hardware detected, yet black image. Camera "bus" malfunctioning?
Hi
Half a year ago my girlfriend accidentally gave my Z3 Compact a rollercoaster ride in our washing machine (full tour). The screen broke, but it could turn on and everything looked fine (gave no errors) when connecting to HDMI.
Yesterday I received a replacement LCD, which gave it a new life. It seems that everything works except for the rear camera. When opening any camera-app, the HUD is visible, but image is black, and no error. If i switch to front camera, which works, and back to the rear camera, it shows a freezed image of the last image from the front camera.
I checked some debug-apps to see if it detects the camera-module, and it does. If it's connected, alle the specs of the camera is listed, and if disconnected, the module is not listed.
I then got a broken Z3 Compact from a friend, and I tested both rear camera modules in both phones. The modules are working in his phone, both doing the same black screen in mine.
I tried hard reset, PC Companion-repair, updates, clearing camera cache etc., but with no luck.
Do you have any suggestion to how I can fix this?
Do you know where on the motherboard I could look for dirt in relation to some "rear camera bus/chip"?
Thank you for any help!
Edit: And isn't it amazing that this phone works to this extend after 2½ hours in 60 degrees celcius (140 fahrenheit) warm water with soap and 1400rpm? Wow! (Btw., all panels were open, and screen totally broken, so water must have been everywhere in the phone.)

I have a similar issue on my partners z3c after the screen cracked, I have replaced the screen and it works great however the camera shows a black screen. I know the camera module is working as I have tried it in another phone. Having searched for this issue I seen it has effected quite a few others not only those who have opened their phone.
what software you used to debug so I can verify that the phone can also see the camera module

This is happening to me too a year down the line of ownership.
Replaced with new camera from eBay still black screen. Between your experience and mine of both testing the camera we've prices it's not the lens, so what could it be.
Need to fix don't know what to do

The camera module itself may work but the chip which handles the rear camera may be damaged even if the phone works pretty good.
So if the chip or anything else related to the camera is dead, you can even try thousands of camera modules from different phones on YOUR phone, none of them will work.
That's my opinion - guy's who work in electronical industry for 3,5 years now and have seen hunderds of differend kinds of damages on different stuff.

I see what you are saying however it would be nice to have an idea of where any chip/bus is that may be damaged to see if it xan be fixed or is replaceable.

Yes, you are 100% right but there's another thing.
In the present times, in a rush of miniaturization, there's a little chance of such reapair to be profitable. The chip/bus may be damaged but in fact not only one thing may be dead... I'm talking about tiny little resistors, capacitors, diodes, transistors (if there are any on the motherboard...) which are many. I'm not saying it won't be possible to repair the phone but without a proper diagnosis what is damaged... I'd be like looking for a needle in a haysack and everyone can tell you that only replacing the whole motherboard will be worth the time.
But still... this is an interesting case of malfunction... I hope you'll find a solution for this or at least someone else will do it for you for a reasonable price.

Problem with my accelerometer.

Just 2 days back my note 8 started having a weird issue. My auto rotation stopped working so I went to *#0*# and my accelerometer ACC Raw Data : X is stuck at -32723 while y and z fluctuate. When it comes to x angle its fluctuating between -82 and -88 when i rotate from portrait to landsape and y and z are fluctuating between 0 and 7. I used an app to test accelerometer from playstore and they all say my X= -78 and its frozen there while y and z are working fine. I don't understand the problem here, did someone face a similar problem? can someone help me out with some solutions. It is a note 8 snapdragon unlocked model on the latest November security patch. All other sensors gyroscope etc are working totally fine they show x y z reading fluctuating.
The weird part I don't understand is how the *#0*# ACC Raw data shows x as frozen while the angle is fluctuating between -82 and -88, and all the apps from playstore showing -78 frozen value. I searched as much as I can about this issue but I couldn't find anything even close.

Just tested my N950U1 (SD, Latest security patch update), all sensors are working fine. This rules out your issue is caused by FW-update imho.

I think that your problem is just that the sensor behaves erratically, I dont believe there is some easy fix, trick or clever app to solve it, in the end it may be a motherboard issue, sorry

All (almost) sensors stop working

Hi everyone,
Almost all sensors stoped working after few days on my brand new Pixel 5 :
Failing sensors :
- Proximity sensor
- Accelerometer
- Gyroscope
- Compas
And maybe others I don't know of...
Fingerprint & cameras are still working.
I've contacted Google support, and they advise me to clean my screen :-/
I'll try a factory reset today before asking for a replacement unit, but my hope is low...
Anyone facing the same issue ?
Any advise ?
Edit :
After a factory reset : same situation

Same here. Had phone for about ten days. All seemed to work. Then thinks went weird over several days. First thing I noticed when going to hang up a call I was no longer presented with phone dialler screen. During calls phone was also spontaneously switching to handsfree. I suspect this was wall tilt related. Then camera images were in incorrect orientation. Google photos not longer rotating images and so on. Installed a sensor app and it reported gyroscope as missing. Clean booted - no change. Factory Reset and still no change. Arranged for an exchange with Google. While waiting for that to pan out, after about a day the gyroscope has come back to life. Although presently reporting no compass. Doe the P5 have a compass?
Anyhow given it working again now I am wondering if some power saving activity is killing the Gyroscope? Waht was the out come with your sensor failure. Did they recover or did you need to exchange?

I tried a random app from the store : Sensor Test with my bad unit and it reported 0 sensor !
I've exchanged my P5 and now the same app reports 30 sensors.
While waiting for the exchange , mine never came back to life : can't rotate, screen stayed on during calls (and auto brightness not working), compass was not working in Maps...
Also on the faulty unit I noticed that the OTA update tooks ages (30 minutes or so, for a ~30MB update). On the new unit, the same uptate took just a normal reboot time.

Thankyou for the update.
While mine has a working gyroscope (at the moment) the proximity sensor is still borked and the screen stays on during calls. I just installed the Sensor Test app and it says I have 16 sensors!

30 for me
Sent from my Pixel 5 using Tapatalk

30 sensors also for me.

Oh my god yes exactly this happened to my phone since yesterday. No auto rotation, no auto brightness, no tap2wake.
I have to send mine back, I hate it. Sensor app does not recognize a single sensor. Factory reset didn't help either
When rebooting like 10 times it changes between 0, 1 and 16 sensors.

I factory reset my phone again and that made it worse. Has gone from 16 to 0 on Sensors Test!
Has lost screen rotation again.

At this point, you should contact Google Support and ask for an exchange.
Like my old one, I doubt this is a software issue...
I hope my new one does not have this flaw.... but this definitely hurt my confidence in P5 devices....

Sounds like issue with corrupt persist partition caused by update gone wrong.

Indeed ! I didn't know about this.
But it seems that the solution is to root the device, and this void the warranty (Google asked me if it was rooted before the exchange).

Weird. It did not happen to mine right after an update, more like 20 days later. Btw Google did not ask me if I rooted the device, which I haven't, but I did unlock the Bootloader for a short period of time to use the android flash tool from Google.
I'm not very familiar with partitions on android but all I can say is that a newly flashed stock firmware from Google itself did not help me

All my sensors work according to that app - it shows 30 sensors every time I launch it - except the proximity sensor sometimes does not actually work right. I was noticing an issue because KinScreen would think my proximity sensor was covered and would turn the screen off because the proximity sensor looked to be covered when it was not, even though the app should have kept the screen on. I downloaded multiple sensor testing apps and the proximity sensor works most of the time but sometimes it does not. Weird. Not sure if I should exchange the phone, I got this with AT&T.

Took a couple of weeks, but I now have a replacement unit. 30 sensors showing and all working properly now. I took it for granted how reliant these devices are on having sensors working for basic things like the phone to work properly. Glad I found this thread and was able to get it sorted out. thanks for the help.

I had to get a replacement PIxel 5 through AT&T for the broken proximity sensor. This one works fine.

Couple of weeks?
I got a new device within 4 days where 3 days were for shipping

Just out of curiosity, am I the only one Google asked if I have rooted my device before sending it back ?
They asked me 5 questions for the warranty (I live in France/EU btw):
- Has the device been impacted, or is the screen damaged?
- Has the device come into contact with liquid?
- Has the device been in contact with a heat source?
- Has the device been rooted?
- Has the device been repaired by unauthorized personnel?

I started an RMA process on their website and no I'm not 100% sure about the other stuff but I'm sure they didn't ask if I was rooted.

I see where Google announced that a fix in the December update could possibly fix the sensor issue for some. I'm guessing you guys got the update and it didn't work huh.

idk I got a new device in december
