Accelerometer location in phone - Vibrant General

Does anyone know where the accelerometer and magnetic sensors are physically located in the phone? Are they on the motherboard or one of the daughterboards? Mine seemed to have stopped working. I have another broken phone I might be able to pull them from if I knew where they were.

Never mind, I got it fixed by deleting /data/systemms3c_yamaha.cfg. I guess it would still be interesting to know where the sensors are...

Galaxy S Proximity Sensor Problems

Hello People,
All of a sudden i am facing a issue with my SGS i9000,
My phone turns the screen OFF when is start a call, Dialing is OK, and the screen goes blank when I hold the phone up to my ear. But at the end of the conversation the screen remains blank, Pressing any buttons wont turn the screen back ON.... after a min or so te screen comes back.. or even when i connect my phone to a charger it works....
what might be the issue? has anyone faced similar problems with their SGS?
I hope there is a solution for this, even the warranty is over for this phone.
any help would be appreciated.
thanks
Have you found a solution? I have the same issue, I don't know if this is a hardware or software problem. I got back to stock rom (froyo JPY) but that didn't solve the problem...
I had the exact same problem and symptoms as you two described a few months ago with my I9000m. So I got fed up and opened it up and found the ribbon cable connecting the speaker and proximity/light sensor partially torn which is why the speaker was working while the proximity/light sensor was not.
You can also try Z-DeviceTest from the market. There's a proximity/light sensor test.
If you've still got a warranty on the thing, I would take it back to shop and have them deal with it. If your warranty is out then you have to do what I did and buy the part and replace it myself.
Here's the good news though. The module itself is pretty cheap at least on ebay.com (search i9000 speaker parts).
I replaced the one on my I9000m and bought another one of these (one to use as spare) because those ribbon cables seem so flimsy (you'll see what I'm talking about if you actually open it up and see for yourself ).
Thanks! I don't have warranty so I've bought it on a Chinese website ~10$ with shipping costs
I have seen this a few times. What appeared to work for me was simply covering the proximity sensors again with my finger for a second, then uncovering again. I say "appeared" as the timing could be a coincidence - but it has happened maybe 3 or 4 times on my phone - and I waited it out the first time, and each of the other times I did the above and it came right back.

unresponsive touchscreen?

My nexus 7 currently has an unresponsive touchscreen. Almost none of my touches are working now and yesterday the tablet was working just fine but some of the touches were not working. Now almost all the touches arent working, did the hardware just fail on me?

Here is what I posted yesterday on another thread, but short answer is that yes it's most probably hardware fault (I don't have picture at work, so can't attach it here).
I purchased my Nexus 7 from Staples during business trip to San Francisco. My device started having touch screen issues after few hours. Factory reset did fix it and I liked the device a lot so I didn't return it as I thought touch screen issue was just a SW glitch. Issue came back at the airport . Unfortunately I didn't have time to return the device at that point. Issue wasn't manifesting itself all the time, but seemed to come up every time I plugged the device in charger. Symptoms were exactly as in this video: http://www.youtube.com/watch?v=uVkvCXDKU2M and the other one in which multitouch is demonstrated. I suspected different applications as a reason to the problem as well as faulty charger. Then I found this thread and became assured that this must be a HW problem.
As I'm living in Finland and don't know when my next business trip to USA will take place I decided to try and fix the problem myself. I took off the back cover and touch screen worked perfectly. Initially I suspected grounding problem but pretty soon came to conclusion that it can not be the case. The problem in my case was the "sponge" pushing (what I assume is) display / touch flex. I have marked that in the attached picture. Even a very light touch to sponge caused touch screen to go crazy. As I don't have the luxury of immediate warranty repair I decided to remove the sponge and my Nexus 7 has been working flawlessly ever since. I can even charge and everything works as expected. When I started charging the device I placed my Nexus 7 on the table. It probably caused slightly increased pressure on back cover and therefore to "sponge". After removing the sponge I can't see any of the touch screen problems I was having. Couldn't be happier as I don't have any of the other problems people have found and device is working as it should, at least for now.
I don't encourage anyone to do what I did, but if you are in the same situation as I was with imported device, you can try to take off back cover and see if the problems are fixed. You should be very careful though not to break the device especially when it's powered on with back cover off. Hope this helps someone.
EDIT: 22.8.2012. Forgot to mention, that turn of WiFi if using device with back cover off. Turning off NFC and GPS won't hurt, although GPS is receiving only. Reason is that antennas are located on back cover.

[Q] Note 3 Proximity Sensor works even after the call!

Whenever I make, receive or even check my balance(which had absolutely nothing to do with the sensor), after the call is over proximity sensor still works! :crying:
Gets pretty annoying some time Later, can't work, play games, watch movies just somehow hand comes in front of it and then Sensor detects it and black out the entire screen!
Please if someone knows anything about it, I desperately need their help! Thanks. :good:
Might sound silly, but have you enabled all your Samsung Air/Gesture commands etc? -- also Smart stay/Pause?
If so, disable them.

I absolutely never enable them they're off since I got my phone but the sensor still continues to annoy me!
What should I do to stop it?
there are a few thread for proximity sensors problems... search and you will find some useful information.
but in short, there is probably some dust in front of the proximity sensor.
a temporary fix is to blow some air in the earpiece... but the problem will eventually come back.
I do this once a month.
The other thing you can do is disassemble your phone, clean the proximity sensor lens, maybe add some kind of protection to protect it from dust... and reassemble everything.

Try going to Settings>General>Application manager>All>Phone and clearing data.
If that doesn't help, try doing a factory reset.
Failing that, try availing warranty, or if you are Knox 0x1, try another ROM.

His problem seems to be a software issue and not a hardware one.

I had the exact same problem with my device... and the problem is hardware (dust in front of the proximity sensor)...
I tried everything, including a factory reset, and the only thing that fix it (for now) is to blow some air in the earpiece.
Next step will be to disassemble and clean the sensor manually
A New Development
Before when I call or receive a call from anybody the proximity sensor still worked and turned the screen off even after the call, but now my phone is acting even more weird!
After the call the headphone jack is also not working!
Desperately need assistance guys, pls help!
Hello,a week ago my proximity sensor started making bizarre things.The screen stayed black after calls etc etc. I went to Samsung in Greece and they changed the sensor.I had the phone back after 4 days...4 difficult days because I am in love with my phone but now everything is working fine. I saw a lot of threads in forums about proximity sensor problems on this phone...too bad!

But I can't send my phone to Samsung because I rooted it and that triggered Knox warranty so I probably need some other way!
If anybody knows anything please help!

Well, you could just disable the proximity sensor and turn the screen off manually by pressing power.
Phone --> Call Settings --> Turn off screen during calls.
Not ideal, but at least you can still use your phone.

Try what he says! if this do not work then, or you have to pay to get your phone fixed or find a way to fix it yourself (buying a new proximity sensor and changing it through the help of videos).The second option will be a pain in the *** and I would never try it as I am not sure if it could go well.
Absolutly same problem i gotta
my proximity senzor is still little red Everything works fine. Like test or calls but is still slightly red. When i restart phone is black but after first call is slightly red and turn black only after restart.. but works fine. Any solution?

Proximity sensor not working after screen replacement.

So I've replaced the phone screen and after that, i cant get the proximity sensor to work correctly. I've tried using the phone with the motherboard not attached to the screen (dumb i know) but i was at least able to verify that the sensor works somewhat. It's like it cant see through the glass.
I'm currently on The "Final" version of Resurrection Remix.
What i've tried:
The app Proximity Sensor Reset/Repair.
The app Proximity Fix.
This terminal code/solution here.
Tried *#*#7769#*#* in the dialer but all it does is clear the dialer and nothing else. Weird, it happens with a good number of other codes too. :/ So basically its an issue in its self I think.
Resetting Cache and Dalvik/ART Cache from TWRP.
I'd settle for having the proximity sensor disable so I can make calls in Snapchat, messenger and the dialer. At least, if I cant fix the calibration :/

There's a tiny rubber grommet over the proximity sensor that probably got lost during repair. I have seen this happen several times on this forum. Usually it's stuck to the old screen.
With grommet: https://d3nevzfk7ii3be.cloudfront.net/igi/SQfQ23vhRFsvbJJT.huge

Oh, wow.. welp... this is probably it then. I am indeed missing that part. however, its lost. I have all the old parts but it's not attached to them :/
This doesn't look like the kinda thing I can get easily. How would I go about getting a new one?

The last guy that posted about this went to the city dump in his small town and found that tiny part. stuck to the screen that he threw out. I was amazed by that. Anyhow, some guys used a coffee straw etc, but from what I remember it never worked right. I can only think of buying a broken 6p from ebay or swappa.com/boneyard but that's a lot of money for a grommet. I'd be searching the carpet or repair area really well first.

Fingerprint Sensor - HW or SW problem?

Please forgive this annoying question, but I recently dropped my K20 (and myself) in seawater in a boating "accident" and, obviously, the phone stoped working immediatelly. Opened it, dryed it, cleaned it with IPA, to no avail.
Then, after 10 days, it came back to life. The only thing not working was the FP sensor. So I bought a new one, but the phone still doesn't recognize it. I remember a problem with some phone in the past that when the FP sensor was replaced, it would not recognize it before resetting some partition or something. Does anyone know anything about it? Maybe the new sensor is busted as well, or the connector from the bottom PCB to the upper one is damaged, I know, but any information would be appreciated.
