[Q] Problem with the magnetic field sensor

Hi everyone
I got a defy+ two weeks ago and it was fine until a few days, it completely lost it, it keeps connecting to either car dock or dock media station all by it self, installed various roms, returned to stock 2.3.6 no way it just got mad, the screen keeps glowing even when nobody touches it, now even the phone's speaker (not the loud speaker) doesn't work in calls anymore, it thinks that the headphones are connected, and also the music doesn't get through the loud speaker, im just fed up, I have downloaded several apps to prevent the phone from entering dock mode with no success, as its a hardware problem. its the magnetic field sensor that went mad, I have no choice but to open the handset and give the sensor IC some heat (I'm very skillful in such things), whats your opinion guys? Does anybody have a picture of the motherboard to appoint me to the sensor IC please?
Please reply as its the only phone I currently own :crying: and in such country there is no warranty no matter what

I solved the problem by applying heat to the AKM ak8973 magnetic field sensor IC using a a high precision heat gun and a bit of soldering past and the phone seems to operate flawlessly now. after searching a little bit it seems that a wide range of Android based Motorola phones suffer from the same problem including Atrix and Razr so this may be the solution, I have attached an image showing the AKM chip that needs to be heated up

[Q] AUX Playback Volume coming from phone is randomly low (but not always)

Gentlemen,
My friend has an original, unrooted S4.
I am waiting for the exact model number, but I believe it's the i9500.
She mentioned that when she plays music from her phone to her car stereo, the volume is often (but not always) low, and yes, phone volume is cranked up all the way.
When this happens, she has to raise the car stereo volume considerably in order to be able to listen.
So far, she's tried two different cables. Also, she's currently driving a dealer issued loaner and observed the same issue.
I've read the S4 FAQ and performed a Search. I couldn't find anything.
Have you guys ever heard of a similar issue with the S4?
Thank you in advance.

...anyone?

OMGGG HAHAHAHAHAHAH
but did you try to install wanam xposed and then you go to Sound and there you can change some sound things, I'll screenshot it.
I don't know if it would work but you could try, and try to download a other music player.

Sound
That's what I use and it is great (I also use DFX Player Pro).

Same here. Phone is set to level 15 and usually have the car stereo set to 30 out of max of 35. Always been like this even when I had a S2 and S3 as well.

Bad call quality, ok on speaker

I have the following problem:
I have bought 2 nexus 4 and combined those two to 1 working N4.
I'm getting complaints from people that they can't hear me to well.
We I put it on speaker they can understand me perfectly.
Would this be a hardware or software issue?
I'm running M915A-CEFWMAZM-2.0.1700.98 hybrid radio and Nexus 5 experience Rom.

The only way you can find out is by flashing a completely new ROM (after you backup, of course) with a full wipe, and trying to call someone. If it works, then it's software. If not, it's hardware.
My take on it is that it's software; microphone is working while on speaker..

Ok, I found the cruelpit.
it was the usb port board that was faulty.
I ordered one from ebay because my port was broken, however it is missing something on the mic.

The bad one doesn't have a black film over the speaker.
I replaced the usb port from an other n4 and sound quality is back to normal.

[Q] Stuck in boot loop, can't access recovery.

I recently repaired a broken digitizer and screen on my Nexus 4, now it is stuck on the colored Google logo forever.

I'm wanting to restore a factory image but can't get the phone to go into anything but boot-loop.
Before I replaced the broken screen the phone booted fine.
Trying this, but won't work.
Press and hold Volume Down, and then press and hold Power simultaneously until the device turns on.*You will see the word Start with an arrow drawn around it.

Also
Wasn't getting seen in previous thread, so reposting it's own thread.
Thanks

for boot loop - check proximity sensor / headphones module connector for properly connection to mainboard .

Will do.

Thank You! It was the headphone jack connector. Totally works now. HUGS!

Headunit not outputting sound through the iso connection.

Hi! I bought a headunit recently and when I fitted it in my car (a Peugeot 107) everything worked well besides the audio. When I put the key in and turn it just to power the headunit, the sound works as expected, but the moment I start the car, the sound is gone, nothing sound-related works. Sometimes when I hit the little "RST" button with the engine on, the sound comes back, but that's not the case every time. I tried looking into the settings, even in the factory settings, I tried looking through all the options, but I didn't find anything.
The unit is connected to my car just through a normal iso port, which has the cables for both the power and the speakers (I do not have any rca cables in my car):

}
My theory is that this is a software problem and it pushes the audio through the rca connectors instead of the iso one. This is the only thing that makes sense to me since a complete reboot of the device seems to more or less solve the issue temporarily. As a workaround, I thought that maybe there's an adaptor to convert my speakers to rca and plug them in that way, but I couldn't really find something that would work.
I am not sure what model do I have since there's nothing on the box that would tell me, but I made some photos of the specs so I hope that's enough to somewhat identify it:
This issue drives me mad to be honest, especially because everything else works fine.
Thank you!
