[Q] Using the external antenna connector and warranty issues - Galaxy Ace II Q&A, Help & Troubleshooting

Hi guys
So i went to a location with bad reception last year,
and i had the bright idea of using a thin metal wire as an external antenna.
I had great reception while i was using it
but when i removed the wire from the plug underneath the cover of our phone
I totally lost reception. My internal antenna seemed to be broken or disconnected.
Is this a know issue with nowaday's smartphones?
because I have done this before with older phones and it gave me no problems whatsoever.
A month ago I decided to see if samsung would repair it under warranty, so I sent it in for repair at the shop where I bought my ace II.
they told me there was a chance they'd repair it under warranty .
but I was smart enough to sent it in with CM10.2 still on it :silly: i forgot to reset everything exept the flash counter
what do you guys think will happen now? will they notice and will my warranty be void?
I know it's my own fault when they do.
thanks in advance,
Boris

I heard from one of forums that external antenna connector for Ace2 is one time only. If you use it then internal antenna will be disconnected for good.That is why the cover does not have a hole for it.Do not worry about warranty.It is hardware issue,not software or ROM related.

External Antenna Connector

Wilson electronics makes an adapter that will plug into the external antenna jack under the back cover. I tried it, and it worked great... until I disconnected it. Then the internal antenna would no longer work. It's like the act of plugging it in destroyed the phone's ability to use its internal antenna. It would work when I reconnected the external antenna, but when I disconnected it, the phone would only get any signal strength when I was right under a cell tower.
Anyone else try one of their adapters with the Captivate? If so, what were the results?

I had no idea that input jack was there until you said anything. What happens if you switch airplane mode on and off after the disconnect of the adapter?

I don't remember if I tried it, but it was restarted many times. I would think that power cycling the phone would have essentially the same effect.

I saw this but never had the courage to try it. Did you pull the battery and try the 3 button fix?

This should clarify things

It's the round gold connector at the bottom right of the SIM card. The adapter (FME on the other end) is available here:

After one BAD experience, I'm not eager to try again. I was sort of hoping that my experience was a fluke and that other people had been more successful.
Why?

Never occurred to me to do that, since the phone booted and it would work when very near a cell tower.
This struck me as either a defect in manufacture, or a design flaw... either in the phone or in the connector. I suspect it was mechanical in nature, and that once the act of connecting the adapter disconnected the internal antenna, something caused it to stay disconnected.
I wonder if this might have happened?

Hello,
I was using a dual band antenna without an amplifier, so there should not have been too much SWR. I've used this antenna for years with another phone AND an amplifier without problems.
The evidence clearly indicates that phone's transmitter was not burned out due to too much SWR or anything else, because it would still work just fine when reconnected to the external antenna. Ditto for the phone's receiver section; it worked fine whenever it was connected to the external antenna. Once connected, thereafter the signal bars went to zero when it was disconnected. Also, as I mentioned, the phone would still function normally, if I was VERY near a cell tower.
The only conclusion I can make is that the connector was designed to disconnect the internal antenna when an external antenna is connected. Somehow the connector or the electronics failed to ever reconnect it when the external was disconnected.

It's NOT a firmware problem
I know you guys are trying to help, but it's not a firmware problem. It's a hardware problem. I was just trying to see if anyone else had a similar experience. I just talked with Wilson Electronics, and the guy I spoke with acknowledged that the connector or board can be damaged on the Captivate. He also volunteered that they don't recommend direct connection with that phone. Well, that's kind of odd, since I only learned of the connector by calling them up and asking which one to use with the phone.
Even though I did not buy the adapters from them, I bought them on the recommendation of one of their people, so I have contacted them to get my money back. We'll see; they haven't responded officially yet. I suppose I can contact the vendor, but they were not the ones who told me it would work...
They have another way to inductively connect the phone. The only problem is that my old amplifier won't work for that. I'll have to get a model 801201 instead of my old 812201 which will run another $250 or so, with a cradle and/or velcro attached inductive connector.

Well guess what!!?? You are in luck!!!
Theres something you can do with hardware problems..
CALL SAMSUNG
your phone is under 1 year old. you have a warranty. call them. flash to stock . and get it replaced then
Why don't you try reflashing the modem or rom? People are offering you solutions and you seem stuck on it being a hardware issue. A rom or modem re-flash takes a few mins of your time. Not to start anything but I do support for a living and it bugs the hell out of me when people jump the gun and won't try other solutions.
I am stuck on the evidence as to what the nature of the problem is. Did you read what I posted previously?
Let me tell you a little more. At the time I had the problem, the phone was still on the factory firmware. The phone had never been flashed.
All the available evidence points to a hardware problem. The fact that the phone worked when in close proximity to a cell tower, that as soon as there was any distance between the tower and the phone there were no signal bars, but if I plugged the external antenna in there was immediately good signal...the fact that the connector manufacturer has admitted that their adapter could damage the board... I don't mean to be unapreciative, but I do support, too (a well a writing the software itself), and I've learned to really think about the available information when trying to deduce the nature of a problem, and it seems to me that you are stuck on a conclusion that the evidence doesn't support.
Besides, I am not looking for help here. As I wrote previously, I was trying to find out if anyone has had a similar experience. If my experience was a fluke, then I would have been willing to try connecting the replacement phone. See, the problem has been solved, but I don't want to have it again.
Now that the manufacturer has admitted that their connector could damage the board, I have decided to get a different type of amplifier which allows an inductive connection. That should prevent further problems of this nature. It's an expensive solution, but an antenna with a bi-directional amp is really useful when you are in a remote area with a faint signal. When the signal is too weak for that, it's time to use the ham radio... but that's another topic, and yes, I have been known to take my jeep off road... way way off the road.

I was referring to the manufacturer of the adapter, not the phone. Samsung was made aware of the problem when I was trouble-shooting the problem. The tech I was talking to blamed the problem on me for using third party accessories not authorized by Samsung. However, since I had been acting in good faith, he did authorize my sending the phone in for warranty repair. I don't know if they can be counted upon to always do that.
I am left wondering how often this problem happens. I used the antenna connector on the back of my Motorola V3xx thousands of times with no issues. It seems really odd to have just connected the Cappy once and suffered such a problem. One key difference is that I don't think that the V3xx disconnected the internal antenna when you connect the external one.

I've seen similar behavior when one of my foster kids mistook the antenna for a screw while disassembling a blackberry.
The antenna jack is a "normalizing " jack in that when you plug something in a circuit is disconnected and when you unplug it restores the circuit.
if there was a problem with the adapter and it applied too much pressure to the middle pin then it may not have normalized and you would only get signal if you sat under a tower.
This is exactly what happened with the poor blackberry.
Glad to hear Sammy is covering it with warranty, other wise you would have been the proud owner of the only door wedge that plays angry birds.

Interesting. Not sure I understand what you mean by normalizing nor"middle" pin, but it was pretty clear that the internal antenna was no longer connected. Of course the unit was not entirely useless as a phone, but the requirement of having to always have it connected to an external antenna to get it to work did make it a tad cumbersome to use...

I'd agree that it's a hardware problem, it may actually be that the internal antenna is burned out. I had a similar problem with the wifi on my old ipod.
I used an aftermarket charger which shorted something inside the device. Consequently, the battery would not hold a charge for longer than 15 minutes AND the it would not recognize a wifi signal, unless I held the ipod within inches of the router. Similar to what you experience with the cell towers, except on a smaller scale.
Good luck.
Burning out the antenna itself would require the kind of amperage generated by a lightning strike. Much more likely that even in your situation some circuitry connecting your antenna to the phone blew out.
In my case there was no overvoltage, just a mechanical connection. I think something just got bent beyond its ability to bend back from... I'm guessing here, but I can see a bar inside the antenna connector. When the center pin of the adapter is pushed into the connector, it will make contact with that bar (the bar is at the side of the opening at 90 degrees to the center pin of the adapter) and pushes it to the side to some extent. I am not sure, but I think that maybe it was pushed a tiny bit too far, and it wasn't able to spring back to its original position. I am assuming that when it is pushed to the side it causes the connection to the internal antenna to be disconnected and that its contact with the center pin of the adapter is the connection to the antenna. I am further concluding that if it doesn't spring back to its original position, that the internal antenna is never reconnected.

Signal Problems after Using External Antenna

Hi,
Am having problems with my GNex after briefly using the external antenna port in the back when I was out in the middle of nowhere.
Before I used the port, I had good signal pretty much everywhere. At current (after using it) I get no bars (not even enough signal to receive sms) except for in extremely specific spots where it will jump up to full. There seems to be no loss of functionality in spots where I do have signal but I cannot find these without driving around for a while.
Are there any known issues to do with using the external antenna?
Thanks in advance for any help or advice.
Sorry, don't quite follow what you mean by 'external antenna port'?
What exactly did you do?

On the back of SGN, under the cover there is a socket to which you can connect external antenna to boost reception. I think this is what OP meant.
OP: You did try to turn it off and on again, didn't you? Maybe try to take out the battery and live it for some time and turn it on? For some reason it seems to help for some wired issues

If you take the back cover off there is a small plug that you can use (it works because I used it for better or worse) with a standard external aerial plug (such as you might have in your car).
I plugged an external aerial into that port at the back so that I could check my phone in a place with very little service.

yeah that thread is the FIRST thing i thought of. in summary to anyone else, on the other galaxy phones, hooking up an external antenna to the port permanently disabled the regular internal antenna by seperating a connection on the hardware. broken as in permanently and physically. needs to be sent for repair.
so i wouldnt attempt this with the nexus either!
I think that is what has happened. Damn.
Anyone know if this is covered by warranty? Otherwise I'll break out the soldering iron.
more than likely not, but it can't hurt to play dumb and try.
I use and external antenna on my galaxy nexus to get good service and i have not had any problems like that, i still get ordinary service most places without it
Which antenna you use? Can you show us where u bought it?
Yes. What model antenna? The proper antenna is hard to find.
Sent from my Nexus in Texas.
Please note that the antenna connector is ***NOT*** meant as an everyday-use port (and not built to withstand such use). This thing is for testing the radio in the factory when the GN is assembled.
If you plug in a cable every day, even with the correct connector, you will likely break the port sooner or later.

If you plugged in an external antenna then you permanently broke an internal connector to the internal antenna. So now you get poor service in all places except the most strong signal areas. I believe there is no way to fix the phone now, its hardware was permanently broke using the external antenna.

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!

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.

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:

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.

[Q] Where is the WiFi antenna located?

Hello all,
For over six months, I have had a WiFi issue with this tablet. I must have dropped it or something because the LCD ribbon came loose but that was easily fixed because other people had the same problem. Unfortunately, I have absolutely no idea where the WiFi antenna is, so I am asking for your help. If someone can provide a detailed picture of it, I would be grateful.
Also, I have absolutely confirmed that this is a HARDWARE issue not a SOFTWARE issue.

if you place your tablet facing down and the camera on the top pointing at you the antenna should be on the upper left hand side.

Unfortunately, I have absolutely no idea where the WiFi antenna is, so I am asking for your help. If someone can provide a detailed picture of it, I would be grateful.
Also, I have absolutely confirmed that this is a HARDWARE issue not a SOFTWARE issue.
Thanks in advance,

I had the same issue after re-attaching the LCD. I ordered a new back cover. There is a wire that runs through it that i must have severed when removing the cover. When i had it apart, i also removed the speaker to visually inspect it. I slightly lifted the pogo connectors under the speaker and that connect the back cover antenna terminals. I popped on the new back cover carefully, powered it up and boom... perfect wifi reception.
Good luck.

So I have learned that the rear case is integral with the wifi antenna. upon inspection of my own unit it was missing these contacts that indeed make contact with the speaker/antenna board. This unit was serviced by Samsung for a dead screen under warranty and came back without the contacts on the rear case. They must be easy to dislodge and whoever put it back together wasn't watching what they were doing.

problems with 1 year old ZenFone2 4gb

Hi everyone, I bought this ZenFone2 4gb 64g, recently it got soaked in my pocket due to rain and now has a few problems such as vibrating motor not working, microphone and speakers not working and screen timeout not working as well.
the problem is that due to job I relocated to Pakistan and here there is no one with replacement parts for this phone neither do they have experience of it. I have located parts on aliexpress.com but I am reluctant to open it up myself.
ASUS says Thayer its warranty was only 6 months so I am left with no options. Help me guys if you know something which can be done.
Thanks
Its easy to open. Need just the right tools. I think you may need to change docking port chip. Its about 6$ at aliexpress. Changed mine.. There are a lots of guides in web. Try one.
If you don't want to change it, just order it and go to some Asus repair center or any cellphone, smartphone repair center. And tell them you're problem firstly. Anyone with normal knowledge about a smartphone could do this.
Ofcourse if you do it yourself there can be problems, that i had : Broken antenna cable (I changed display- twice), broke the battery (i was a fool ).
Little Instruction: Take back cover off, take all the screws out, they are about 10, don't remeber really. Unplug SIM, SD flex cable, that is on the docking port chip.
Remove Antenna, very carefully. And replace it.
