Creaking/Buzzing noise while calling

I have a Captivate Glide (AT&T version), (bought used from ebay) i'm using in in Europe, and the call quality is just weird. The quality overall wouldn't be that bad, but when someone is talking to me, there's a constant creaking/buzzing sound which makes it really bad and hard to endure. It only happens when using speakers, with headsets it looks ok.
Do any of you have any similar experience?
I don't know if it's software related, looked for some modems to flash but couldn't really find any. Tried to update software but it's not supported via Kies and also get some weird error when trying to update from the menu: "DM initialization is not ready. Check network or SIM card" (might have something to do with the non-at&t sim?)
I currently have UCKL1 build & baseband.
Since it's ok with headset, i think it might be hardware-related. Do you think it's speakers are faulty?

if headsets and bluetooth devices are fine then there is a good chance that it may be speaker related.

Yeah, that's what i thought too. But i would still give a fw update a chance, is there any newer than what i have/where can i get them? Can i flash them with Odin without voiding warranty?

Take a look in the development thread there are many Roms now available for you to try. Oh and if you flash, you do void your warranty, hence why you will see many threads on people trying to put their phone back to stock for warranty service or updates witch no longer get pushed with a modified Rom.

Well, i meant i wanted to try stock, official, unmodified ROMs, what i would get from official updates, so it wouldn't void my warranty.
I found one here: UCKI3 but it looks older than what i have.

sounds like your speaker is popped or a bad connection to the speaker, certianly not anything software can fix, altho i havent pulled my glide apart some phones have a 2nd speaker for "load speaker" others im told use the same speaker but run thru a different "preamp" so bad connections anywhere in that circuit can cause fuzz.
as far as warranty work or keeping it intacted at&t wont honor any warranty on a 2nd hand phone, new in the box or not, subscriber or not (i have tried) so if it was purchased thru ebay your likely out of luck there. ebay does have a 30 day guarantee so if your in that window you can prolly get a refund.

That's bad news. And even if AT&T would take care of it, it's not much of use because i live in Europe. I guess the best thing to do is investigate if local Samsung services can repair it, and if they can, talk to the seller to pay for it's price. If they can't repair it then... i guess i'll have to live with the 30 day guarantee and send it back...

yeah talk to the sammy repair folks quick ebay has really stepped up their game as far as ixing problems & what not. just do all your communications thru ebay so you/they have a record of the situation even if the seller doesnt want to help ebay may step in & fix to keep everyone happy....good luck!

Called the Sammy service, turns out they don't support this model in this country at all, and i guess this stands for whole Europe, so repairing is not really an option unless i go/send it to USA for this.
I don't know what to do, should i just send it back? It's a really annoying error but don't know if it's worth all the hustle...

it is a nice Android device but remember it is a phone and if it bothers you to use it as such I would try to get it returned or serviced.
Sent from my SAMSUNG-SGH-I927R using XDA

I looked into the return policy and only found this:
"Your ability to return an item depends on the seller's return policy, which you should be able to find in the listing or by asking the seller.
While we encourage sellers to be clear and specific about their return policy, it's up to them whether they accept returns.
If your item doesn't match the listing description, you should contact the seller first. If that doesn't work out, you can open a case in our Resolution Center."
Are you sure there's a 30 days guarantee in all cases? How can i do that?
I already tried to contact with the seller several days ago but no answer yet.

p600 wifi turning off on of on off on....

Ok this started last night, tablet has been working flawlessly for the last 6 months or more.
What happened was, I wasn't able to use the Internet. Just wasn't working. And every 20 seconds or so it would flash up at the bottom of the screen "connected to (my router)".
So I turned wifi off and on, which usually fixed connection issues, but didn't help. I also restarted router, even though my computer and my phone isn't having any issues.
So then I went to the wifi settings screen to see if there was any way to reset networks. What I saw was this:
If i turn wifi toggle on and watch the screen, it would scan for networks, find the list... Couple seconds pass... Then the toggle would switch itself off and back on! And then it would start looking and finding networks again, and then off and on, and etc etc.
I have tried a factory reset and cache reset.
I have also downloaded the 4.4.2 stock rom and installed using odin for a totally new install.
Still does it.
Any suggestions? Seems very strange. It's under warranty but it seems like an odd hardware fault, seems more like software but I dunno.
Help me xda, you're my only hope.

I've been searching the Internet all day trying to find someone else havin this problem... But I seem to be the only one. And noone seems to have any suggestions.
At the moment I'm having to consider a warranty dispute, but that means however many days/weeks without the tablet which I use on a daily basis.
Not ideal Samsung.

Hey. I had the EXACT same problem. Even made a video of it and showed it to the service point personell. Turning on off on again and again, it also displays in the settings the switch just switches itself without any action of mine. It was a hardware defect. send it in and get a new one, better than being annoyed by it. Mine did it on a 5-10sec interval length...

Yeh mines probably every 5-10 seconds...
So this is definitly a hardware fault? In which case I'll have to get in touch with john lewis and hope they will do an exchange in store. If it involves having to send it off to samsung and waiting for it..
Anyway thanks for replying to the question, shame it wasn't better news haha!

yeah sorry to be the one to tell you this is a faulty device but it seems like this unit ain't free of errors and there quality control is somewhat sketchy.
Which android version are you running? I am asking because I run kitkat and also have relatively ****ty battery life. I use it for university so I have the screen on and write notes during lectures. Usually it lasted 7-8hours but for about a week or two it now only lasts 4-5 hours of screen time which is really ****ty.
I read somewhere that this might be a motherboard issue and if it is it might be somewhat corellated to our wifi problem. In my case they replaced the wifi module and gave me back my "old" device but this is having bad battery life so I am thinking about sending it in (again). I did however root so I would have to make use of the warranty provided by the seller, not samsung itself, since my knox is tripped.
(in Germany the sellers also must provide 6months - 2 years of warranty and there was a judgement in Europe that rooting must not have any influence on wether your device still is under warranty or not. sadly this only applies to the warranty provided by the seller, not the manufacturer)

Is your BT on and are you connected to a 2.4 GHZ network?
If so, turn off BT
I get random WiFi disconnects and reconnects from 2.4 GHZ networks when BT is on but not connected. Though, Ive never noticed the wifi switch going off and on.

I am running 4.4.2 or whatever, kitkat anyway.
Bluetooth is off, I never use it on my tablet. I dunno what network type I'm running, might be N or might be B/G, but whatever it is it what it has been for months as I havent changed any router settings lately.
I have restarted the router twice already in case this was a network problem, but the network wouldn't cause the wifi to toggle off and on, it would just cause disconnects etc. Least I assume so. I may try this just in case but like I said the network type hasn't changed lately

John Lewis are saying they won't exchange it, it will have to be sent off to Samsung for "repair". Meaning I'll probably get sent back a refurbished second hand one with a dodgy light bleed screen, as I expect they have hundreds of those lying around now.
Oh and it'll be up to 28 days. For a premium and expensive device that's less than 6 months old this just isn't good enough.

I had mine replaced as well but dont remember wether I got a new one or just my old one repaired... should have written down the IMEI I guess :-/
you're from Bristol, don't the EU rights apply there? If so your retailer should be obliged to replace or repair the device.

Anyways my replacement was done through Samsung and it took 6 days. But then again idk differences between UK and Germany...

XIAOMI MI A1; Just turned off by itself randomly when i was using it. Cant turn it on

Ive only had this phone for 1 month and while I was on my bed using the phone when suddenly my phone just powered off by itself and it wouldn't turn back on. Ive tried plugging in the charger but it didnt do anything. I tried to force it on but it didnt do anything. Also, it wouldnt turn on in any way possible.. I suspect that my battery is damaged but im not too sure since I do not know much about smartphone technology and i think its also because that i used the bluetooth function with my car and i noticed that the phone was slightly hotter than usual, maybe this was the case but i dont know. Please help me out here.
Thanks for your time.

Go to the repair shop official if theirs one, unofficial if their isn't. Or contact those you got it from & let them hassle with it. It could be many things from simple battery ribbon to fried SoC... Anyhow even if you got it on wild still in most countries who ever sold it to you must provide one year warranty by the law.

Got it, and mines official so yeah but I had apps such as Blackboard, Chrome and Google Drive on to check on my assignment work and details. SO if I were to get my phone fixed would they still appear in the background to continue the process?

What's cloud synced is recoverable regardless. As stated before it depends on what is the case of the problem. Could be a power stripe from battery which is easy & you don't lose any data or in the worst case it could be a main bord socket in which case you do as everything is on it (SoC, RAM, NAND...)...

Severe brightness issue (screen largely unusable)

Hi all, I have a problem with my stock T-Mobile US S9. A few months ago this weird thing happened where if I turned on my screen immediately after it turned itself off, only the top few lines would be visible. The whole screen would take input, but you could only see a little below the status bar, maybe. If I waited a bit and then turned the screen on, it would work normally, with the whole screen visible and looking fine.
It's gotten progressively worse to the point where this happens most of the time I turn the screen on. However, I've found two workarounds:
1) My Always On Display is set to turn on when I tap the phone. If I do that, the AOD works as normal, and if I then turn on the phone screen the phone screen works fine. This only works when Always on display is set to turn on on tap. It does not work if AOD is set to always be on.
2) If, when my screen is glitching out I hold the screen up to a reeaally bright light (like inches from a lightbulb), the rest of the screen turns on. It's weirdly green tinted and kind of stuttery.
Turning off automatic brightness does not fix this issue. If tried booting in safe mode and even factory resetting the phone. Issue still persists, including on screens like when the phone enters recovery mode.
The fact that I can get the screen working normally using workaround #1 makes me think this is a software issue, but the fact that it happens on the recovery screen makes me think it's pretty low-level. Any ideas? Anyone else had a similar issue?

I gave Samsung tech support a call and the level 1 tech I spoke with seemed to think that it was a software issue and that I should bring it in to be looked at by a technician. I'm in Maine at the moment and there's no Samsung or UBreakIFix stores within two hours, so she suggested taking it to Best Buy to look at. Not amazingly helpful or surprising.
If it's a software issue though... I mean this is my fourth Android phone and I've rooted and flashed ROMs on all the previous phones anyway. I don't want to lose Samsung Pay, so I'd rather not unlock the bootloader, but is there a way to flash the stock operating system or something? The exact model number is SM-G960U

It's a firmware or hardware issue not software as a reload* would have fixed it.
The firmware has been corrupted (needs reflashed) or there's been a hardware failure.
Best to send it in for repair or take it the a Samsung Experience Center as they can reflash the stock rom and have advanced diagnostic tools.
*make sure all system apks are running on factory load and have not been updated after the reload.
Updates, destroyers of worlds...

If that’s really necessary I’ll do it. But the closest place is out of state and when I called them said it would take 4 hours just to do a diagnostic. That plus the round trip... if there’s a way I can save some time, I’d like to.
For example, if one possibility is a stock firmware reflash, that’s something I’ve never done before on a Samsung device, but not very different from things I feel comfortable doing. I've flashed roms and rooted many android devices in the past. From a preliminary search , it looks like there's even a leaked tool online to do so from Samsung called Odin and that I just need to find the latest SM-G960U image with the right "csc" code for my carrier (I think TMB for T Mobile US). What would be even better is if one of those diagnostic tools you mentioned leaked the same way that Odin did.
Any recommendations on either diagnostic software or firmware reflashing? Or would you strongly advise leaving that kind of thing alone? I would like to still use things like Samsung Pay at the end of all this.

If it's under warranty let Samsung deal with it. A good tech with experience is invaluable.
Rather then waste time the extra ride might end up being the easiest solution. You could also next or 2nd day it to the center and back, make sure it's insured and packaged well.

That makes complete sense for something under warranty, but unfortunately my phone isn't. The S9 is about three years old now, and the Samsung rep was quick to tell me that the device was no longer covered. It looks like a mail-in repair service would cost about $175, which I'm theoretically willing to pay, but not if I can just handle on my own for free.

In that case you have nothing to lose by reflashing it. Hopefully that gets it.
Otherwise it be hardware... probably a good chance this actually the cause.
The good news is the 9's are available for a couple hundred in good condition if need be.
I was considering getting the 9 as a second phone (have the 10+) as the 10+'s haven't come down much in price.
Samsung current lineup sucks.

Huh. Well, before reflashing, I tried something I found other people suggesting for a related problem: https://eu.community.samsung.com/t5...t-bars-black-screen-issue/td-p/1745470/page/7
It's an app called OLED Saver. It's not perfect, the screen still has an odd green tint to it unless I use one of the tricks I was describing above. But I no longer have the issue where most of the screen isn't visible.
I might try reflashing anyway, will post results if I do.

Yeah, no joy. Reflashed by downloading the latest firmware using Frija for SM-G960U with TMB as the CSC, and flashed using Odin v3.13.3. If anything the problem is slightly worse now, but OLED Saver still mostly seems to fix it. I guess it's just a hardware issue with a weird software workaround...

Same type of brightness problem here as you describe, on my new S9 (G960U) - - Model starqltesq - CSS XAA
The product is under guarantee, but as it is imported from Hongkong to France, I don't have accesss to the Samsung local representatives and have probably to send it back to Hongkong ...
I will keep you updated if I learn something about the problem and the solution ....

Wiping the cache partition stopped this happening for me for around 24 hours but it came back this morning. On the Note9 forums someone posted that setting animations to .5 in dev options fixes this. I will try it.

Disable animations instead. It wastes resources. Personally I like seeing a fast, snappy OS do it's thing with no middle man needed. Lol, you end up waiting for the animations rather than the OS.

I've heard of people flashing custom roms and that resolved the issue permenetly, but can't find anyone willing to give some real feedback. I posted a topic asking this question, but haven't gotten any replies..

Not very helpful, but a work around could be to use Screen Filter

Hey could you explain what exactly did you uninstall and how?
After uninstalling it wireless charing stopped working or what did you mean by cant charge the phone?
Did it fully resolve the green screen issue?

Some people noticed that problem after upgrade Android 9 to 10.
At this moment we have some facts:
1) OLED saver temporary solves problem
2) disconnect NFC module solves problem, some people on xda and on the yt confirm that
3) heating back cover using heat gun can help - I Discovered that some weeks ago
Interesting comment from the yt:
Sour Words
Sorry to say this, but green screen issue is a hardware fault not something an update can fix. One of the updates from Samsung is causing the CPU to over heat and in return permanently damaging the oled screen. Not only that but also compromising the battery as well. The only fix is the replacement of both the oled screen and battery. This repair is entirely the fault of Samsung due to a faulty update that over works the CPU capacity. Therefore my advice is for you to return your device back to Samsung and lodge an assessment request. They charge a small fee for the assessment, but the entire repair should be compensated by Samsung. Be firm and keep the pressure via emailing them to insist on Samsung covering the repair costs. My Note 9 is almost 3 years old when green screen issue happened. They fixed the entire thing free of charge. But I kept firm and didn't let them bully me into charging me for the repairs, which was their fault in the first place. I must admit, my phone despite its age, is in perfect condition. Not a scratch on it. Which I know contributed winning my argument for the repairs. So if you have psychical damage, I doubt you will have a chance. Good luck to all who will give this successful method a go.

Note 10+ stuck at watchdog reset

Hi all. I am baffled as to what happened to my phone. It has no mods and is running stock android 11. It was absolutely fine, not having any issues at all, and I realized I hadn't rebooted it in a few weeks. So, I did a plain old restart.
And it died.
It won't do anything no matter how long I hold the power button down. The battery is fully charged.
Tried to get to the recovery screen by holding down volume up and power, which did nothing. Then I tried vol down and power and got a screen I've not seen before: SS RDX Watchdog Reset.
And here I am stuck. I plugged in a usb cable to my laptop and now there's a device connected on my laptop called msm_upload which I can only see from the windows Bluetooth and other devices panel.
I have no idea what to do from here and I'm desperate.
Any help would be greatly appreciated.

I've never used smart switch before. If my pc doesn't see the phone, how would that work? My phone doesn't show up in my laptop except as a Bluetooth device called msm_upload that I can't figure out how to interact with? I guess I'll need to install smart switch on the laptop and hopefully it will see the device?

That's true and who knows it might work. essentially trying anything to see if it will somehow make a difference. fingers crossed

Very strange.
Sort of sounds like it's bricked.
Play with new firmware/software, win new prizes. I could go on...
You need to navigate to the boot menu somehow. Keep playing with the buttons; sequence and ***timing*** is everything.
If you can drain the battery until it auto shutdown that might get it... much latter.
Disconnect the battery and force a hard reboot.
Otherwise it's repair shop time.

I went to a repair shop out of desperation. Had to drive over an hour to get to it as I live in the country, and he basically said it's dead. The fun part is, I called my warranty co and of course, they aren't honoring the warranty because "they don't insure phones that cost over $999" which mine did when I got it. But of course, there was nothing that said they didn't cover my phone, which is why I bought their lease/warranty plan.
So, basically, I have a brick that I owe $591 on yet, and they couldn't care less. At this point, I am willing to try anything at all because I have no other options. I already filed a BBB report against them after spending over an hour on the phone with them to no avail.
Any ideas at all would be very helpful at this point.

Also, I CAN still get to that SS RDX Watchdog Reset screen and it will scan an SD card (because I tried it). The problem is, I cannot for my life find a stock Note 10+ ROM anywhere that I can actually download. Wondering if I should just try to throw a custom ROM on it instead? It's obviously not going anywhere otherwise.

There's a stock rom for it, obviously.
If you can degrade to 10, do so.
The boot loader version will dictate if you can or can't.
I'm not experienced enough to advise you on this but that's what might be needed.
Again play with the button sequence/timing and try to get into the boot menu.
Just a slight difference in timing or the wrong sequence and it won't go to the boot menu.
It's not likely but possible the buttons were remapped.
Try taking out the Sim and SD card.
My guess is you can get it to go to the boot menu but until today I never heard of this happening.
A apk timed out because of not rebooting for so long? Don't do that again... at least reboot every couple days.
Malware is another possibility.
Last resort talk/send to Samsung.
Play with it... Androids wuv attention.

I'm having a RIDICULOUS time trying to find a clean copy of stock ROM for my Note. Every single one I've found either ends in a dead link or I download it and it ends up being corrupt. This is no small feat as I live in the middle of nowhere and the only ISP is Hughesnet, which is neither fast, nor unlimited. It literally took me 4 hours to download a 5gb alleged stock ROM only to have it be corrupt.
Isn't there anywhere to get a clean copy of stock??? I see a lot of mods here in XDA, but as far as regular stock SM-N975UI, either I'm totally missing something or there isn't one here.
Can someone please help me find one that is clean? SamMobile's download is limited to 15kbps for non paying members and their copy has been downloading literally since yesterday and is only at 900mb. Living in the country has its perks, but high speed internet isn't one of them. Nothing worse than checking on a download that was running all night to see it say it still has 2 days to go.

You'll need a much faster connection; that slow, that much data, the download has a great chance of being corrupted.
Maybe have a 3rd party download it and send it to you by mail etc. Samsung could... if you could harang them into doing so.

According to the authorized service center I visited yesterday, they don't even have access from Samsung. They are directed to send the phone directly to Samsung, which just floors me. I asked the tech if he could at least flash stock and see if we could get it to load, since I definitely can get to the SD card from Watchdog and it will read it. His reply was nope. I called 2 other repair shops since I was in the city already and got the same story.
Back in the day, rooting Android 4 was easier than this! Do you know of any reputable sites for stock roms? SamMobile is definitely out. And many I've gone to will list my stock, but when you follow the links, the file is no longer available. This feels like a bad X files episode at this point. LOL.

Talk, write to Samsung and lean on them.
You'll probably end up sending it in. Take detailed pictures of the phone before boxing it and as boxing it. Double box it and pack/seal it well. Insure the package!
Fight with Samsung if they try to charge you more than $50. Expect trouble... Samsung's tech support is one of the worst on this planet.

Finding stock ROM should not be that difficult, by browsing through the forum, Guides, News & Discussions:

I went to a repair shop out of desperation. Had to drive over an hour to get to it as I live in the country, and he basically said it's dead. The fun part is, I called my warranty co and of course, they aren't honoring the warranty because "they don't insure phones that cost over $999" which mine did when I got it. But of course, there was nothing that said they didn't cover my phone, which is why I bought their lease/warranty plan.
So, basically, I have a brick that I owe $591 on yet, and they couldn't care less. At this point, I am willing to try anything at all because I have no other options. I already filed a BBB report against them after spending over an hour on the phone with them to no avail.
Any ideas at all would be very helpful at this point.

File a complaint with your state attorney general's office.
Against the warranty company and especially the carrier.
Lean on the carrier, verbal breach of contract because the warranty company refused to repair it.
I'd stiff the carrier out of principle. It's likely they wouldn't bother to take it to small claims court.
Before you do that though lean on them like a cheap suit, call, call, call. Talk to their retainment group. Don't give them a moments peace. One time I called Verizon close to 30 times in a week before they finally issues a full credit over a Direct TV breach of contract. If I was you I be seeing red...
