[Q] Car dock and speaker phone problems

For the past 2 days, no matter what ROM I flash, car dock comes on at every reboot. I've never used the car dock app, so I'm at a loss as to why it starts up every time I reboot my phone. I exit out of car dock, and it doesn't start back up until the next time I reboot.
Also, every time a call comes in, or if I make a call, speaker phone is always on by default. Again, this happens on every ROM I flash, and it's only been happening the past 2 days.
I'm rooted, currently using Warm Z, with netarchy 4.3.2 cfs more havs.
I should also mention that I've tried multiple kernels with the hopes that maybe that would solve the issue, but sadly it hasn't. Any help would be appreciated.
Well I have no idea why or how, but both issues have solved themselves. Nothing was installed or uninstalled, and my phone is back to normal.

Anyone have any ideas at all?

I'm having the exact same problems with my G2. If the Evo and G2 are anything like many of the other phones out there, they use a magnet to switch into car mode.
My problems started when I first started using a belt pouch with a magnetic closure - before I knew about the magnet/car mode thing.
Has your phone been exposed to a magnet for any period of time?

My phone is doing the same thing! Did you find any solution?

On my G2 I did a SuperWipe and then installed a new ROM and the problem was solved.

I believe that the car dock mode is regulated by the pin out of the power cable. Recall it being that two of the ground wires are attached in the car dock and not in regular power cable mode.
Also in car dock application, you can go into the menu option and turn it off so that the car dock application isn't the default action when it senses that connection.
I actually own the car dock, but hate the application since I usually only dock the phone when in GPS mode.

Having the same problem.

I've had the same problem for a month now anybody find a solution really annoying at this point.

I had Car Dock starting for no reason on my phone. What I was found was that launching Car Dock was done so by certain pins in the Micro USB port on the phone. What was happening to me was that the Micro USB plug on my charger was messed up in a way that made the phone think it was plugged into the dock instead of just a regular charger. I bought a new charger on Ebay for like $3 and never had the problem again.
I've read that some people have Car Dock launch without their phone being plugged in. Almost all of them noticed that they had some sort of tiny debris within the usb port that was crossing the pins and causing the app to launch. Cleaning out the port with something like a toothpick should help eliminate that possibility.
Hope this helps.

Yes I read that as well, and tried cleaning the port with a soft tooth brush and compressed air and didn't help. the most annoying part is the load speaker is the default for incoming/outgoing calls and the media volume is stuck on full, much to load for headphones. More than likely the pins are touching and so small that I can't see them much less straiten them out. Trying to find someone who can solder a new port, so if anybody has sent there evo to have the port fix with good results I would appreciate a good recommendation.

S3 3.5mm jack

I noticed today that my headphones / car stereo etc is only playing out of the left speaker unless I jiggle it. At first I assumed it was a wire going so I tried 5 different aux cables and 2 different headphones, it's all the same deal.. have to look for that sweet spot to make it play in both speakers.
I bought this launch day and I am pretty shocked the 3.5mm is going already, I've already tried cleaning it with dust off (air can) and it's still the same. What does sprint generally do to fix this? I have insurance, but I really hate getting a refurbished phone back... had bad luck with them in the past! Let me know if you guys know anything else I can try to repair it myself or if its a lost cause and just let sprint replace it.
thanks!

Honestly...I would just let sprint fix it. I don't think they would send you a totally new phone, but instead ask you to take it to a repair center. I have had that problem before but with a few cheap aux cables I had. I always tried a fresh new one and it worked fine...maybe all of your cables are going bad haha you never know!

Yours is defective. I use my 3.5mm jack everyday no issues.

yup its just from plugging it in and out too much over the past month, they replaced the jack free of charge in 20 minutes, works great again thanks

When I got my GS3, the same thing happened to me. I was about to unroot and call Sprint for a new phone... The I saw a thread with someone else with the same problem.
Turned out that what was wrong was that I just hadn't pushed the jack in far enough. Sounds to ridiculous to be true... But try it. Push your headphone plug in nice and firm until you hear a resounding "click".
I felt dumb, but saved me the grief of returning.

yeah I thought that at first, it wasnt that. a pin inside the jack somehow became loose enough to not make contact with the plug. the guy showed me after he fixed it.

[Q] Can this Gnex be saved or should I sell it for parts?

It looks like I finally got burned buying a phone from kijiji. I'll save you the gory details. It seemed fine when I met the guy but once I got it home there were issues.
My computer won't recognize the phone. When I plug it in, nothing. No errors, just nothing. It doesn't show up in Device Manager. This is my fourth Gnex and I have the Android SDK installed and the Google drivers. I reinstalled them just in case but no luck. Upon further playing with the phone there are other issues. When I plug in headphones, the speaker stays on and there is no sound in the headphones. The volume up rocker doesn't work and the 2 batteries I've tried drain like crazy.
So is it a lost cause? Unfortunately, I'm in Canada and can't get a cheap one from the Play Store and now I'm a little gun shy about buying used. On the bright side, I'm back using my Nexus One.
Any help, ideas, sympathy would be appreciated. Thanks!

As long as it has a good working screen it's probably repairable. Sometimes the USB port pins get bent and don't connect, or short to ground. You can try bending them back into place, or just replace the whole USB port if necessary. Not that big a deal. The audio out jack might also have a loose or broken connection. The battery drain is the most troublesome. I would just take it apart and reseat all the connectors and check for bent or broken ports, which can be replaced.

Disable wake on headphone insertion

Ok this has been killing me for the past few days. It seems my headphone doesnt fitbquite nice enough and a little wiggle causes it to wake my phone up. Is it possible to disable the phone from waking up when I plug in my headphones???
This is frustrating because im constantly fighting my phone to stay off!

I didn't know this was that big of a problem.
I always thought it was useful so you can efficiently open your music right when you put in your headphones.
Try turning off the Context Buddy in the display settings and see if that does anything.
Sent from my SPH-L900 using xda premium

Context buddy is already off. It's weird, see, the phone never gets interrupted music wise, but for whatever reason the phone detects it being unplugged and plugged back in (without disrupting audio)
I do have headset blocker but that doesn't effect it, so I'm hoping that someone knows any files I can edit to disable this function

Ok so this is cool, after taking a look at my phone, and messing with the headphone jack. My freakin headphone jack is ****ed up. Something is wrong and the pins aren't properly clicking onto the damn jack. What the hell. I never abused the headphone jack and just like that it's broken. This is BS
I guess I thought it was doing this for a while but that's only because I haven't listened to any music for a few days. I just had my headphones on today at work to muffle the factory noise and kept hearing my phone lock and unlock, but now it's for sure.
My phone has a damaged headphone jack! this is messed up. One of the reasons for wanting a samsung in the first place was hoping they had a better headphone jack setup than HTC does/did (which were physically cracking the headphone jack) and now it looks like my phone is messed up too.
This is ridiculous...
I'm going to see if maybe lint or some crud is stuck inside there...here's hoping that's all it is...
nope, it's the headphone jack. This is bs, I'm going to see if sprint will replace it under mechanical failure or something. The phone's only 3 months old and has been in a case its entire life, never dropped/abused or anything.

I've had this phone since the day it came out and never had a problem with the screen turning itself on while my headphones were in, which is saying a lot seeing as I use my headphones every single day on my 1 hour bus ride to work.
And also never had a problem with the headphone jack...
Take the phone to Sprint and tell them the headphone jack is messed up and they will surely give you a new one.
Just you know, be all "frustrated" and what not in the store lol.

Yeah, that's what I'm planning on doing. It's messed up that a 3 month old phone wears out its headphone jack, where my 10 year old cd player still works perfectly fine.
there's no physical damage, it's just that the pins inside have worn out.
Do you think they'll care that my phone is rooted hah. I mean, this is 100% unrelated to being rooted ya know?
I tend to use my headphones 8 hours a day, 6 days a week on my phone. So i guess it was bound to happen. I just hope it never happens again.

If anything before you go just do the "triangle away".
The application can be found in the app store, it resets your counter.
Like I said, I've had my phone about 5 months now and use my headphones every single day and haven't had a problem with them.

If you are worried about them finding root (they will probably look for before giving new device) go into superuser and unroot through there if you want.
Sent from my SPH-L900 using xda premium

Dont need triangle away since my counter never ticked with thebroot method I used. Im not worried though since sprint works on rooted phones as long as root wasnt the cause. In this case the headphone jack wore out from daily use
Sent from my SPH-L900 using xda premium

I have a temporary fix. It seems that the headphone detection pin has worn out severely, so I looked around and found out soundabout (which i was already using to disable the speaker) has an option to force sound to the headphone without using headset detection. Works perfect.

Headphone Jack issues

I am facing headphone jack issues of late with my Note 2. I have tried many headphones and earphones in my Note 2 and only the left audio works. If I wriggle around the audio jack and if I put the wire in a certain position, then the right audio comes and again stops even if the wire moves slightly. Its very annoying that I have to adjust the cable all the time. It is most likely a hardware problem with the jack. Should I give it in the service center or is there anything that I can do ? I am rooted and using a custom ROM. Will they repair it under warranty, if I flash back to stock ROM and reset the counter ?
Thanks

I had this problem with my mp3 player. It's very frustrating.
This picture is from a mp3 player, but it's the same in our phones. I think something is broken inside the yellow cirkle.

I have the exact same problem. Its a shame bcuz Note 2 has been the best phone Ive ever hsd.

Try cleaning out the port with a Q Tip and compressed air. No liquids if it continues then I would have services. Before sending it in have the stock firmware with kernel and recovery. And test it after that before sending it in.

Agreed, a can of compressed air may end up costing you significantly less time and money!
Sent from my GT-N7100 using Tapatalk 2

Mine is doing this too, but only with certain cables plugged in. Those with a wider flat plug have the issue, where those with a smaller rounded plug do not. I am attempting to just get a cable for my headphones that have a smaller rounded plug, instead of getting the phone fixed, since it works with some. I think it is more an issue with not being able to push the plug entirely flush as the phone is curved, than with a defect in the contacts (though nothing would suprise me).

I've just sent my note 2 to Samsung (via Vodafone) to have the headphone socket fixed.
They refused because it was rooted It was still on stock Vodafone firmware and I forgot to unroot it lol

Note 2 Headphone jack fix for me
I too had this same issue. I have figured it out. I could not get the headphone jack to work, cleaned it and everything. I thought my phone was done. Then I was changing out my sd card I noticed a screw loose. The one right between the camera and the flash. I tightened it up and sure enough the headphone jack works now!! Not sure if this will fix all of your issues but just thought I would throw that out there.

Mine eventually went out completely, so i ordered a new one on eBay for $6 US. It literally took 5 minutes to fix.

Sorry for the thread hijack and thanks for the reply
I am in the UK and Vodafone were adamant that they (or Samsung?) wouldn't fix it because it was rooted. He then agreed with me that rooting my phone would in 'no way break the headphone socket' lol, still wouldn't repair it though
Do you have a link or anything that says EU phones must be fixed if they are rooted? I'm going to send Samsung a snotty email and it would be useful.

One of many authoritative sources: http://matija.suklje.name/rooting-and-flashing-your-device-does-not-void-the-warranty-in-eu
It boils down to that the repair centre has to maintain warranty as long as they cannot prove that rooting is the direct cause to whatever problem you have.

Exactly this. I was going to have to unroot , until I saw this. There is also another little screw to the right of the jack when looking at the back of the phone with the cover off. Check this one too. They were both loose on mine.
LOL I had a flat bladed jeweller's screwdriver I had pocketed at home for no reason. Saw this at the office, and VOILA. Fixed. Fate.:laugh:
/edit
This also seems to have cured the hissing audio problem when using the audio while charging with a USB, which according to Samsung "is normal".

headphone jack issues.
II bought my note 2 used. The headphone jack was broken when I bought it. I've had the jack replaced twice in the past month. It keeps going out. The sound turns to static but if I move the plug, it will work a little while. Is this a note 2 defect or did I just buy a bad phone?

I got this issue just few weeks ago. I purchased a replacement audio jack, and installed it today. Not working. Then I tightened the screws a bit, and it worked! For a good ten seconds... and the issue remains.
Does anyone know the inner workings on this device? It seems to be a connecting issue. I tried adding some pressure around the audio jack area on top of the plastic cover, but it didn't help... The phone works just fine otherwise, and I happened to notice that the original headset volume rocker and microphone works but I can't hear anything!

i have this problem. nothing works

Having an interesting/annoying time with my n7105.
Dropped it one too many times, and the headhphones audio turned into a static hissing mess!
I found that by just smaching the phone against my knee or something solid, the audio would return for about an hour.
It got worse and worse and eventually I decided to fix it. I purchased a replacement audio receiver jack and installed it, but the problem still remains, so I'm unsure where the actual issue is occurring.
I found that by tightening a screw just below the audio jack, that it fixed the problem. I have to tension it just right... Too tight and the issue returns.
I think the issue must be with the connector on the motherboard, where the ribbon cable connects. I say this because the screw I'm tensioning to fix the issue sits pretty close to this, and would be pressuring this down and around.
So I'm not sure how I'd fix this without replacing the entire motherboard.
I'll crack it open again soon and have another dig at it.

I've been doing a bit more research and found that someone may have already done the work for me.
I'll attempt this and report back with the result.
Post from Android Central forums
After my earlier rant I opened my phone and have managed to fixed my knee smacking problem. The problem was a bad ground between the screen and motherboard. I have added a picture of the two metal surfaces I cleaned (circled in yellow) to get the good connection back. These are not pics of my phone because it was apart obviously but it is the same phone. My sound is 100% crystal clear I believe the problem comes with dropping the phone and the connection going bad due to lack of enough screws in the area of the connection. I also ran the screw directly into the motherboard instead of through the plastic backing in the same area I circled. Stop smacking you're phones!!

Well I attempted half of this. I opened the phone up again and cleaned up the connections with some 100% Isopropyl rubbing alcohol (they had a bit of gunk on them).
Started putting the phone back together and cracked my screen. Hurray!
finished putting it back together and there's no improvement.
I'll pull it apart and place the above screw directly into the motherboard as instructed and see if that helps.
Will update upon completion.
