Water damaged - Samsung Galaxy J7 Questions & Answers

Anyone end up dropping there phone in water because it just happened to me, landed with the bottom quarter Making a good dunk in the toilet. Trying to find a teardown to see what I can do about fixing it.
Still works but my usb port is flaky about connecting but seems to charge while powered down. The speaker no longer works have yet to test the ear piece. Used the voice recorder to test the microphone and it works but it's nothing but static. Headphones work and records fine. Late right now so no one to call to test that yet.
What's the process for buying a logic board with a bad imei to swap out with my board, the bad esn boards I'm finding for sell are about 30 bucks cheaper then good ones like here.

Samsung captivate speaker problem - return for new one?

Okay, so my samsung captivate speaker is pretty much broken and doesn't work properly anymore. I've had it for about a few weeks and now the speaker just doesn't make any more sounds. Music will not come out etc....i can get sound to work for a little bit but its only temporary and goes back to not working, i just hit the speaker part and it randomly starts to work again but it doesn't stay like that so im wondering if i can return it.
I bought it off craigslist so i don't have the receipt or anything like that, i also don't have the box since its at a friends house. Im wondering if i can go to an AT&T store and exchange it for a new one no questions asked without the receipt or box and the fact that i didn't buy it from at&t personally but it is originally from an at&t store (obv). Or will i have to do the other dreaded task of sending it back to samsung and be phoneless.
I doubt AT&T would accept it without anything at all, is it really that hard to get your box at your friends house? But besides that unless you can prove you're within your 30 days they wont do anything unless you have insurance. In your case I'd contact Samsung directly and they can probably run the serial, obviously you're still within a year lol.
okay, damn thats a shame.....i have to go through samsung. Im pretty sure its past the 30 days already too.
I had speaker problems when I slipped my Captivate into a really clear case made by Incipio. I believe that was the culprit. I also had to hit the phone against my palm to get the speaker to work again. I remove the phone from the case and played an entire album via speaker. No problem there. I returned the case and bought a Body Glove skin. Better.
Yea......the speaker is somewhat working fine now after playing youtube and some songs again......will see how it holds up.
I might just not send it back and go through all the hassle, i think it got messed up when i dropped it, shame cuz it was the only time i dropped it, maybe something got a little loose.
I havn't had the speaker not work on me for a good 6 hours so far will keep monitoring it.
me too. i bought it on ebay. So i dont know if at&t will fix it or replace it.
My external speaker stopped working for the first time today also. I read over on an AT&T forum that if you press on the speaker it will get it working again. I just tried it and now my phone works again. I had to press a little below the speaker.
Just another notch in the belt for what a crap product Samsung made. I've never dropped my phone or anything. Others are having this problem so it's a build quality issue or something. The connection with the speaker must be weak.
so i guess there's no other way to fix the problem except getting a new or refurb one?
Sound not working over loud speaker
Unplugged my cappy this morning and headed to work. All has been very quite...too quite, then realize that my cappy isn't making any noise
*panic mode* no media sound, ringtones, etc...
Read on the at&t forum that you can press firmly on the speaker and it 'fixes' the problem. WHAT!!!....that's a crappy cappy fix, anyway, what can you do... Speaker is working again, for how long? I don't know.
Same here, dropped my phone a couple of times. External speaker starts acting weird, connection keeps coming and going. Tapping fixes the problem only temporarily, it goes back to being dead only after a couple of seconds / minutes. seriously crappy. Everything else works fine though, headphone conenction / telephone speaker seems alright.

Yeap. Pressing down on the speaker did the trick. It sorta fixed the problem. Cheers man.
As mentioned, if you can press down or slap the back of the phone and sound begins to work again, you have a shorting speaker or perhaps a poorly contacting ribbon cable. You can open the phone up and re-seat this in hopes it will help. It uses a ribbon cable design with a lock snap to press it against the contacts. I'd advise gently lifting the contacts with a small needle or tweezers then re-seating and retesting.
If you do that let me know and please report your results. You can also replace the speaker as well. I have an extra I don't currently need.
I purchased my Captivate on eBay just after Christmas, turned out the camera had a problem in the lens so I told them it was randomly rebooting. They allowed me to go exchange the phone since it was under warranty (had insurance but didnt use it) and since then, I have replaced it 2 more times.
See if you can talk to them on the phone and find out if your still covered, luckily I have a warranty exchange store near by, so it was real easy for me to exchange.
edit: forgot to mention I never had a receipt, I told them I got it from a third party seller. Since its an ATT phone, they should still accept the warranty
Press on the speaker if you have no sound!
Don't mean to dig up a dead horse but if you are having external sound issues I can verify pressing on the speaker does fix it.
This I discovered after 2 nandroid restores and a 4 reflashes with clean wipes. Plus removing several apps I had just installed.
Now I get to reinstall everything and update my ROM again.
It pays to search before panicking.
Intermittent speaker issues, specifically when I turn the speaker vol up to Max while playing music, burping the phone helps,

Its funny you said this because I bought my girlfriend a captivate a couple months ago off eBay. The phone itself is fine last month the speaker also went out. It would only work if she tapped on the back of the phone. Well we called AT&T and told them, all they did was check the imei and see when it it was bought. It was only 11 months so its a good thing it failed now and not later. After a couple hours of troubleshooting with the good folks at AT&T and doing a master reset even though I told them that had nothing to do. They then transfered me over to the warranty department where a spent a couple more hours doing the same troubleshooting I did as with the AT&T reps. At last they said they would send me a new captivate. You should call the worst they can say is no.

For those of you who do not have warranty or insurance, there is a fix for this.
I just got done with re assembling the phone after a fix I performed. It is real easy to do.
Things you need:
-A screwdriver (whatever the size is when you open the back cover, the four screws you see, that size)
-A small flat head screwdriver if you have one (not necessary but would help)
-Patience and some common sense.
Ok, to start off follow these steps http://forum.xda-developers.com/showthread.php?t=740022 to open the first 6 screws and then how to pop open the screen from the bezel(this is when a flat head screwdriver would be useful).
(go just to the step till the fifth picture in that thread, no need to go beyond that opening things!)
Now, you would see a screw on the left of the speaker. Now, other threads said that by loosening that screw the speaker would work. But, I did that and still had issues so I opened the phone like 4 times in total before I found out what it was. Now, notice that the speaker unit has a cable (orange colored) running into the main phone chip. It is connected there through which it functions. When you open that above mentioned thread to open the phone there is a picture showing to remove the that belt from the board. Follow that instructions, flip that tiny black clip up to remove the belt. In some cases there might be a blue sticker kind of thing on the belt, just take off that sticker. The problem seems that the belt is loosing contact which doesn't allow the speaker to get the sound input to put out sound through the speaker. So, take off the belt by flipping that switch and re insert it out there. Try to push it in properly or enough to align a white line on the belt and the chip. There is a white line to guide us there. That line should be totally straight when the belt is inserted appropriately. And now, flip that clip down and lock it. If you have loosened the screw left to the speaker, put it back in in normal force not excessive(no need to be more gentle here). You cannot leave it loose because it makes the whole unit move when it is loose eventually pulling off the belt from its place which causes the sound cut outs. The whole trick is to get the belt right in its place. So, make sure it is tight but not extra tight after you have managed to get the belt right. Put everything back together and now when you screw the last 6 screws again, the one in the top speaker corner affects the speaker unit, so don't push it too hard in. Just normal screwing. The rest should be done properly with normal force. This should solve it. I figured this out after opening the phone 4 times. And now playing songs since the past 6 hours non stop and its back in action again!
For all this, i did put in the battery and start the phone when I had opened it and tried messing around and figured out what was killing the sound, so this should be the ultimate solution to it. There is nothing else that can be affecting it now.
Most people must had faced this because they dropped their phones before which made the belt to move and hence the loose contacts inside. If not then, there are high chances that you bought it from someone or somewhere who had dropped it before!
Well that's it! Also, don't freak out in having to open the phone. You should just go to the step till the fifth picture. Which is very easily achievable!
Go, have fun with your WORKING speakers now!
More Useful speaker fixes
I am on my second captivate, I got a refurb since the speaker died on my first one.
My second speaker just started dying.
Before I had even read this thread all the way to the end I decided to tear apart my phone to get to the speaker to see if there was something loose that i could re-solder or reconnect.
Have you ever dropped a magnet in the dirt and picked it up and it was cover in little bits of iron?
I discovered that when I peeled the little metal cover off the speaker that it was covered in little tiny bits of metal that were stuck to the magnetic face of the speaker. I don't know how much this affects the speaker function but I cleaned it off and plugged the speaker back in and put it together and it works great.
I took a small flat head screwdriver that was magnetized and carefully scraped off the little bits of metal wiped it all clean. you wouldn't believe how much crap gets through that little tiny screen. I was able to peel of the little metal cover with my fingernail. It was very easy to take off, you could even remove the speaker cover without disassembling the the back cover.
I am not certain if my cleaning fix will solve the problem since I had removed the cable and shoved it all the way back in, but it might help make the speaker louder.
Anyways there's my first post. Hope it helps you all.

Yes this solve the problem for the speaker no phone punch
I put a small piece of thick tape under the battery cover near the speaker and this keeps pressure on the speaker.

Captivate Headphone Jack problem!!!

So I don't know if it's my ROM, my phone, or what, but I've tried 3 pairs of earphones, and sound only comes out of the left earbud. When I push down on the headphone jack I can sometimes get it to play faintly through both, but usually not. I'm putting the earbuds in all the way, they just don't seem to function. I treat my phone very well, and this really sucks, since I bought it for the music player mainly. Do you guys think AT&T will replace it? (After returning to stock, of course) or am I out of luck? Also, the water damage indicator shows no signs of water damage, and the phone itself looks great, since I usually keep it in a silicone case. I'd really appreciate any insight into this problem. =\
Thanks in advance.
**also, I'm running the newest version of Darkyy's Raw steel.
Silly question: Have you checked inside the headphone port for lint?
This happen to me with a phone once. Took me 2 weeks to figure it out. Since my phone was in my pocket all the time I had apparently gotten some lint in the port and packed it in tightly when I next tried to plug in some headphones.

Yep... Still nothing I notice that when I push down on the headphones farther than they "stick" I can get sound to play through both earbuds... huh...
Have you tried the earbuds that came with the phone?
The phone has a one year warranty, so if something is wrong they will replace it. But why mention the water sensor? Did it get wet at some point?
Of course AT&T will return it, if you bought it from them...?
OK guys, just an update....
So I called AT&T and put on my innocent, "what can haz root?" persona, and after a quick runthrough with a CS rep ("What's a factory data reset?") they issued me a refurb captivate under warranty. Just so everyone knows, this IS covered by the warranty, assuming you didn't do any physical damage to the phone.
As for the headphones, the left earbud on the stock ones went out after 4 months. They were freaking nice while they worked, though. =\
Thank you all for your suggestions and input.
I am now experiencing this issue for the second time. The first time it was under warranty so I just sent it off but now it's been over a year and I don't think they'll fix it.
For me it seems like my earbuds are what's causing it. They're really nice Shure brand earbuds with a pin for an in-line mic. I find that when I use them in certain jacks I have to pull the plug out a little bit to have them line up correctly without the sound getting super distorted. I think they're knocking something out of place.
However, since the earphone jack has been shot the second time I have a larger problem, the ear speaker is no longer working. Seemed to happen at the exact same time.
Anyways, I think I might get a OneX after this summer so I'm willing to crack this thing open. Any ideas as to what could be the issue?

USB port issues

I am having issues with my Captivate's micro-USB port being loose. This is my second Captivate, and although it's still under warranty, the first one was RMA'd with the same issue. I never drop the phone while charging, etc, and I've tried multiple chargers so I really can't see why this would be happening. Both phones were 1008 versions, not sure if the 1008 is known to have this issue, or if I just have horrid luck. If anyone here can solder / fix the phone, I'm hesitant to go to AT&T again, as last time they made me go to the store and have the person working there verify that the USB port was not broken (luckily it still charged if you held it a certain way, and even more luckily I was able to flash stock before returning it!). Anyways, this phone is a refurb, and I did call and almost get it replaced as soon as I got it, as it had this issue slightly upon arrival, but decided it would be a hassle. It's only been about a month since the RMA, so I'm pretty sure that if I try now, they're going to get very mean about it, and possibly try and send me a bill for the phone, not to mention, the guy at the AT&T store will probably think something is up.
Any ideas are welcome, I love my Captivate, and I was just getting into develping on XDA :S

I actually found a fix to my issue. I actually was looking at it one day, and figured that in theory, it should be easy to fix, so I (CAREFULLY!!!) took a small knife I had and gently bent the inner part of the port up just a tad (it looked like it was too far down, and yes, I know it's supposed to be far down, but not that far), and it actually worked perfectly.
Thats weird... It kinda has to be what you're doing with it, since mine doesn't even have an irregular slight wiggle.
Obviously it could be just your luck but i doubt it.
edit: and who cares if the att dude thinks somethings up... its your $500..
Like I said, the second one actually had the issue upon arrival, but it was barely noticeable (the USB port would work, but if you moved the phone a lot, etc, it'd disconnect, then reconnect). I called in and talked to them, but decided not to RMA because it'd be a pain (in hindsight I should have...), and the problem just got worse.
Is the port internally lose? Or just when you plug a cable in it wiggles alot? Ive heard about people stretching the casing inside the port from alot of flashing (plugging in the usb). But if the hole port moves inside the phone thats no good lol. You should try to locate a nearby device service center and show them the problem and make sure you walk out with refurb thats fine. Dont worry about the people at atnt questioning it. Hell I use to walk in and just say "gps dosent work" and they would switch it out no questions.
What you said makes sense, the port looks like it's pretty sturdy, it's just that the cable wiggles a LOT, and it makes it hard to get it to even register.

I also had this issue, i opened up the stock Samsung Cable end to find that two of the four wires had insufficient strain relief and broke off at the solder joints

Water Damaged OPO, Speaker Issues

Well I dropped my OPO into a creek in about 2 feet of water. After being submerged for about 15 minutes I thought it was toast. I put it in the ol' bag of rice for a few days and to my absolute amazement it booted right up and works flawlessly except for one issue.
The loudspeakers are so quiet at full volume you can barely hear them. Earpiece speaker works fine. I popped the back off and took the speaker assembly out and removed one of the two speakers. It looks fine and there is no moisture in it. If I set it on the board contacts at full volume I can barely hear it play.
Do you think a new pair of speakers would fix the issue? Can I test the board outputs to see if its putting out enough juice to run the speakers? Any thoughts or input would greatly be appreciated!
Hey - same happened to me! Except much less water! I put my OPO in a damp pocket after heavy rain (!) and it seemed to be a goner. 2 days later after putting it in a bowl of rice it works fine now, phone speaker and microphone work, only thing not working is the lower/music speakers. Headphones work fine too. Any easy way to replace/fix this? Heard a loud crackling/static noise coming from the speakers after the initial water exposure if that means anything.
I'm another one looking for a solution to this issue.
Anyone found one? Thinking about trying to replace the speakers, but not wanting to faff with that if that isn't the problem.
Word of advice to everyone. Don't drop your phone in the bath!!!
I am in the same situation as well, sent it for speaker replacement and the repair guy showed that even replacing the speaker module will result in low volume output. Nothing can be done unless replacing the motherboard maybe?
I sent it to a local shop, not the service centre by the way.

This happened to me as well. I was biking and crashed, falling into an overflowing ditch, completely drenching my pocket and my OPO inside.
I immediately took it home (my laptop got drenched too ;w; that one's at Asus being fixed) and left it in rice for the rest of the day, only to find that the speaker played, just barely audible at full volume, and the microphone and ear piece worked perfectly fine. I bought replacement speakers shortly afterward and replaced them, but, like kaz93 said, didn't do anything, it was still really quiet. It must be on the logic board or something.
I'm probably just gonna get the Google Pixel when it comes out XD
Speakers are the most sensitive part of this phone. I also had to replace mine after watering the device. You can afford them cheap for just a few bucks on aliexpress and they work perfectly

Just had to share this experience....

Well I have been a owner of a LG Nexus 5 for the past (almost) 2 years now, in fact I am coming to the end of my contract very soon and will be able to either goto another company or get a new phone.
Anyways, sometime ago I experienced a problem with my microphone and external speakers not working, or at at least some of the time... After a bit of research online I found out my problem was related to a connection inside the phone that connected the bottom assembly to the main board at the top of the phone. It required me to remove the back panel and a few screws to remove the plastic cover, but the poster suggested putting some tape on top of that connection to hold it down more firmly to the socket it connected too. So I did this. I put some black tap (electrical tape cut to fit.) on top and then assembled the phone again. Viola, It worked!
Well, a short time after I decided that I wanted to update my phone from stock kitkat (4.4.4). Always been curious about custom ROMs and gave Cyanogenmod a try. Not only that I got bold and tried the nightly releases of the new marshmellow update. After some time I started experiencing things not working, like the camera, and a lot of freezing, hang ups and random reboots (not so much the reboots as the constant freezing). Often I couldn't get anything on the screen or the phone to respond from a locked state and when I did, often the phone would lag so much, that doing anything would take a long time and proved to be impossible.
I started thinking it was the nightly releases as the source of my problem and just kind of shrugged it off and figured "they will eventually fix the problem". I kept this thinking for quite some time. But it occurred too me one day that something else was causing the issue I was facing for the simple fact that the lag started showing up in the recovery mode (also custom) and a lot of times would continue to show up after I rebooted my phone. Hence, would rule out any 'software' issues I was facing.
I began to think that my problem was hardware. Maybe it was just time for a new phone. But still months away from the end of my contract, this meant I would have to pay off the 'problematic' phone first before getting a new one. I really didn't like that idea. So while looking into this problem, in a last ditch effort, I opened my phone again. Dunno why but I also decided to get rid of the tap on the connection I tried to fix before... I popped off the connection there and had a look at it. It didn't seem damaged in any way nor did the socket. Strange as it was I put that connect back in the socket and put the cover plate back on making sure not to torque the screws and assembled everything back up....
Now the mic and ext speakers work just fine and the phone is working like I just opened the box and took it out for the first time. And I have not once seen any problems... I understand what's happening here... still just wanted to share that for it was definitely weird or what?
https://drive.google.com/open?id=0B0pUNVcVRCJ7MThMc0NHLUNkSEU
Sorry about the link, only way I can upload an image.
Just so there is no confusion... an image of the effected area, inside the phone. The arrow points to the connector and more importantly the area of the connector that seems damaged. If I press lightly where the arrow is pointing on this image, the assemable at the bottom (speaker/mic) will work, indicating a loose connection. Although after visual inspection, I cannot see any damage to connector or the socket. I suppose the only way to really "fix" the issue is to order a new part. As stated previously, already tried tape on the socket to help hold it down, but that seem to cause just as many issues with the phone performance. Any other suggestions?
When ordering a replacement part, you need to be careful because there was another XDA member replaced the same part with a cheap 3rd party solution and the phone would not charge until he replaced it with an oem part.

Does anyone else have issues with there ext. speaker and mic not working?
An update on the phone;
back to square one. My ext speaker and mic will not work. And that socket has something to do with the LCD connection on the screen as it will black out if just the right area on the back of the phone is pressed. Only way to revive the phone is to long-press the power button for a reboot. Then will come up fine but speaker and mic still do not work.

Wow, that sounds pretty low level tactics of LG... just shameful really, but not hard to believe these days...
Quite honestly, I am just going to replace the phone. Think I got a pretty good run out of it and think its pretty well time for an upgrade. Anyway, for the reason I got the phone, it wont matter the speaker and mic don't work. Just going to use it for development and it will be a good test device.
Oh an this post is related to this thread so I thought I would link it for it may help someone else facing similar problems....

I'm not sure that LG had anything to do with the low-quality replacement parts.
If I were you, look for a n5 with a smashed screen that is suitable for parts.

Good idea, except the iphone is the most popular phone around here ... find it pretty hard to find one, been looking. But thanks.
I have seen quite a few busted n5 phones in Toronto. I have managed to get working phones with a smashed screen for as little as $30 which is rare for Toronto. Average I pay is $40 to $50. For this price, I either use the phone for parts in several phones or I get third part screen from Aliexpress for around $40 CAD.
I just want to update this as well...
I am fairly certain (now thinking about causes) its not really a design flaw, but more so because I frequently sat on my phone when it was in my back pocket...

It was not me but I had that same experience. Replaced with a cheap oem and it didn't charge after that.
I found out why. The charger usb socket was not connected to anything ! Unbelievable! It lacked the black plastic backing for that part of the cable to connect to.
