[Q] Encoding telephone conversation? - Android Q&A, Help & Troubleshooting

Hello guys,
So... I've got this idea: Is it possible to encrypt/encode (in real time) the actual sound recorded by a phone while conversation, and decrypt/decode on the other phone?
Well, maybe I should try to explain myself a lil'bit more
[side story]
My friend is a bit paranoid, and he thinks that we can never talk on phones about anything because the government will wipe our asses. I tried to convince him that they don't have a reason to eavesdrop us, but again... paranoid.
In theory i guess that it is possible to catch the the voice recorded by the phone, encode it, then send the encoded data as sound through the network, then decode it on the other phone
So i was wondering about there might be a program out there that capable to do this. Or if not, i might be able to create one of course that would take a while considering, I have no idea about how does the phone calls work in the program level. But I have some free time and I am ready to learn, (if that is necessary). But first i am curious about what you think about this?
Is it possible?

is there a way to overclock the XDA?

is there way how to overclock the XDA? I was able to install the JS Overclocking Software, but the unit hangs when set at 236 mhz.
there is a link trying to look for it.......I read about this......hmmm! :shock:
overclocking is possible, but whenever it goes to suspend it hard resets the device (at least it did that for me)
i strongly disrecommend it...
Again I have to ask, is it worth the instability, and possible damage to the unit for a few extra Mhz? I will never understand the need to overclock. Would your really notice it?
Yes, if you have several apps running, you will notice it, but I don't think it's worth doing it...
Hi,
I'm experiencing some very noticable lag when it comes to switching applications; especially when the XDA is turned off and a phone call is received.
From my own testing, when I call my XDA from a landline telephone, it rings twice from the landline phone (or so) before the XDA even powers up and then switches to the phone application (which can sometimes take two or three seconds) - by this time, the call has been routed through to voicemail because the call wasn't picked up in time - Argh!
To help speed things up a bit, I make sure that there are only a few applciations open at any given time, but I'm thinking of running the JS Overclock software that is available at http://www.pocketpccity.com/software/pocketpc/JS-Overclock-2001-1-12-ce-pocketpc.html - has anyone else used this, and if so, what did you think of it?
Thanks,
I use the overclock program, and have NEVER experienced a problem with it.
Generally, I'll leave the XDA default. If I'm running a program that needs more horsepower, I'll crank it up. If I think I might be away from a charger for a long time, I might crank it down to save the battery.
Works very well for me.

Gsm testers!

I am experiencing a problem with the speakerphone. The buzzing noise that is known to happen on GSM devises when u r close to speakers, TV's, radios etc is happening when I turn on the speakerphone. Is this a known problem for GSM TP2 devices running android? Is there a fix or will I just have to deal with it till it gets worked out?
EDIT
I have done some testing and lots of reading. Its seems that the "GSM BUZZ" only happens on the 2G network. I will explain exactly what I am experiencing, when I am on the phone if I turn on the speakerphone the speaker starts buzzing, also if I am on the phone and recieve an alert/notification or press a button the same buzz comes through the speaker and to stop it I have to turn the speakerphone on then off. This is a real problem and it is happening on both GSM devices I have access to. I need people with GSM devices to do test so we can see if this is happening on all GSM devices. All I need is for u to make a call with 3G turned off or if u do not have 3G access simply turn the speakerphone on and report what happens. Also make a call and press a key, I belive that if keytones are enabled the buzz will happen and if not it will be buzz free. Somehow sounds are turning on the speaker while on the phone. Lets get this fixed!
You have a giant WinMo6.5 logo in your sig... Why don't you stick to WinMo?
Does it happen in WinMo? I don't have any speakerphone issues, but I'm on CDMA.
I asked for help not a smartass comment. stop being condescending towards people just cause u have a little knowledge. if all ur gonna do is talk down to others than y even post anything? u can go ahead and come back with another post trying to put me down but all it will do is make me laugh. please do not post unless u are willing to help me understand my problem. I know u think ur routine of accusing people off not reading before posting makes u feel like a man but to other u come of as a douche bag.
Now to answer ur question, CDMA devices so not genrerate the buzz through TVs and speakers that GSM devices do. My question was asking y the known buzz comes through the speakerphone. its almost like android thinks the speaketphone is part of another device.
now ur other question, I don't stick to WM for the same reason everyone else doesn't, my device allows me to do things like boot android and Ubuntu so I have the freedom to choose my OS.

You obviously do not what you're talking about.
Plus, I asked a simple question and you failed to answer it in your long drawn out whining post. Meh.
FYI, CDMA devices produce a similar noise in other devices, not sure why you think that's isolated to GSM. iDEN does the same thing - perhaps the frequency is different, never really looked into it.
Your sig just makes me think you prefer WinMo, and kinda makes me giggle as it is comically large.
Well, I've got a bit of the same problem. But it only occurs when I'm either ending the call or when i have to touch the touchscreen during the call. Then it just goes haywire and give the bzzzz noise..

i do know what i am talkin about. its called "THE GSM BUZZ" cause it happens on gsm devices.
i am so sorry i did not get ur approval before postin my sig. u remind me of one of those kids that feel bad about ther self so they try to insult other to make themselves feel better. u picked the wrong one. i ain't puttin up with ur ****. u may get a pass from other cause u helped a few people but u r constantly being rude to anyone that ask a simple question. ur way is not always right.
i asked for help not for comments on my sig or to be told to stick with a certain OS. this is America and i can like two things at once. yes i love WM but if i wanna use android on my device i will and do not need u to make up my mind for me. if u wanna help me get to the bottom of this buzzing noise fix this problem then cool but i do not need ur condecending remarks.

Actually, I'd be shocked if a CDMA device actually caused the "GSM buzz" in other devices - Interference maybe, but not the distinctive buzz. It's due to differences in the channel access schemes between CDMA (To be specific, ANY form of CDMA, whether it is Qualcomm CDMA2000 or UMTS) and GSM (iDEN is similar to GSM)
CDMA systems a channel access scheme that has all devices transmitting continuously when active, but using special coding so that the receiver at the cell tower is able to "pick out" the individual handset signals. Since the device is transmitting continuously, the RF power envelope is fairly constant.
2G GSM/EDGE (not UMTS), iDEN, and the long obsolete D-AMPS use a different channel access scheme, time division multiple access. Each handset is assigned a time slot (or slots for EDGE) to transmit in. On a given channel, a set of slots is contained within a frame. Each time a phone's assigned spot in a frame comes up, it transmits. The end result is that the RF envelope pulses on for a short period every frame. Many other devices will rectify and filter the RF (unintentionally) resulting in a signal that follows the RF envelope - a low duty cycle square wave with a frequency equal to the frame repetition rate.
I have no clue why a device would cause such interference to itself in only one OS. It's not an issue anyone else has encountered to my knowledge. Original poster has a pretty poor attitude and atrocious grammar that is difficult to read. (People who can't be bothered to type out the word "you" really bother me for some reason...)

but its not just my device. my friend also has a tilt 2 and she lives in another part of the state and her speakerphone makes the same buzing noise on android. its kinda weird cause i have not seen other people askin about this problem. its just a buzzing noise that makes u not wanna use the speakerphone. also it happens if there is alerts while using the phone and then the only way to stop it is to turn the speakerphone on then off. it has to be affecting others too. it could not just be happening on two devices.
I see exactly the same thing on my rhod100 (de).
I also have another problem which existed for a long time: On some occasions, after booting to android, audio is completely gone. I test it by placing a call and checking if there is any in-call audio. Plus, on such an occasion, media files also do not make any sound, and rebooting the phone is the only solution. Enabling speakerphone does not help, even if I hear the mentioned buzzing sound.
I remember seeing something about audmgr_enable and that the arm9 did not respond to an rpc in the logs. I can post them if that happens again.
I think there are a fair number of known issues with the speakerphone.
I haven't bothered to try it myself, the only speakerphones I have ever used with acceptable audio quality are Polycoms.
edited first post.
well... i have the same problem and i've tried all the android variants out there...
finally someone else that has this problem. it is a big problem for me cause it makes the speakerphone unusable. I wish someone with some knowledge would recognize this is a real problem and try to fix it. I think somehow android thinks the speaker is part of another device.
are ALL the users with this problem ONLY experiencing this issue on Android or WinMo as well?

From his description, it seems to only happen in Android.
I talked to stine briefly, and he hasn't tested it - is there a bug open on it? If you really want dev attention to a problem, and there isn't already a bug, file a bug. If there is a bug, post to it and add some logs - there might be something funny going on that's easily spotted.
Also, you haven't done any triage from what I can tell - does this not happen on a certain combination of rootfs, kernel, or system image? If you can recreate a scenario of where it doesn't happen, that'll help narrow it down. If it's always been happening... it'll be more difficult, but also good to know.
One of our top kernel devs has a GSM device, he's never mentioned this issue. If I talk to him today, I'll mention it to him.

it happens no matter what build or combination of parts. it only happens on android anytime the speaker is on and if the speaker isn't on and any kids of alert or noise such as a button press happens the speaker comes on and buzzez till u manually turn the speakerphone on then off. basically the same noise that comes through any audio device when a GSM cell is near is comin through the speaker. i am pretty sure it only happens on 2G cause the "GSM BUZZ" does not happen with a 3G signal. if ur guy test he'll for sure hear it.
I just managed to confirm the issue on a Tilt2 - needed to force 2G.
(I almost never use speakerphone and am almost always in 3G areas so never noticed this before.)
Apparently there are some audio routing patches in the pipeline already that might fix this.

Interesting - did you ONLY change system.ext2 build, or did you also use a different kernel?
had this problem a few times (froyo) but never occurred in my last call.
I think it may have something to do with a data connection before or during the call? There are a few problems originating from data connections. Perhaps it was latest kernel that fixed it for me? Will have to wait and find out.

The other party can't hear me clearly. No high-frequency

Hello everyone. We got 5 phones during the holidays from Microsoft retail store in LA. Right after we put our sim cards and start using our phones all of us realized that other party can't hear us clearly (as an example when I use my AT&T Tilt 2 other party can hear me way better). Looks like the microphone cuts all high-frequency sounds. Either it's a microphone problem (could be defected batch) or some other settings. We've already checked all possible settings with no success. Does anybody else having the same problem?
Other than that phone is really awesome!
OS version: 7.10.7720.68
Hardware version: 0002
Radio: 16.23.02.26_A_16.27.00.23U
Any suggestions?
Nobody else experiencing this problem?
Is it possible that something is wrong with this particular batch?
TITAN - Lousy Sound Quality - Other Party Can't Hear . . .
I also have most people I call tell me I sound all distorted, (Or occasionally worse.) When I have someone call from my phone to a land line, to me the receiving sound has a buzz, almost tinitus, frequency shifts, & sometimes pulsing of the signal. Don't know if this might be the microphone, transmission, or what, although it seems consistent to my Titan, Occurrs in many places . . .
I'm surprised that no one else (except you) seem bothered. I tried unchecking the signal boost / loudness check, but to no avail.
Any suggestions? How is the sound quality you others are getting? Hope it is just a bad unit that I can swap Friday, or else I'll go back to my HTC AT&T Tilt-2, (the titl-2 is a much inferior phone, but with decent sound.)
My gilfriend constantly complains that she cant hear me too well. I think its because the phone is pretty long and the mic is right on the bottom. She can hear me better when i put the bottom part closer to my mouth. Its quiet annoying. I dont think its call quality but just bad positioning of the mic by htc.
@artzznyzz Where did you buy your phone?
UPDATE on bad / inferior Titan Sound Recepton:
Following a suggestion, I un-set (TURNED OFF) my attentive phone 'flip for speaker' option, so as to NOT automaticially go to speaker only when turning phone over & setting it down for hand free use during a call. This seemed to help some. (But a drag as this was a very nice touch - Most of my usage is in office / for business)
Per 'Cubanaso', above, I am also being more attentive to not holding the phone at the top where the antena may be, and also holding it lower so as to speak nearer the microphone on the bottom edge of the phone. (Why the heck did HTC place the main voice microphone so far out of the line of normal user speach? Maybe an attempt to save $ & go with only one microphone for both normal handheld usage, and also for face down on the table hands free usage? It would seem better to have two good mics, and via software use one for main speach, and the other for noise cancelling input, depending upon orientation.)
(This specialized custom grip is a pain because of aviding so much 'verbotten' contact with the phone - Can't touch the top off/on switch, nor the camera button, nor cover the microphone, nor where the micro-USB charger is attached. Too many restrictions, until new habits are learned . . .)
Anyhow, some more minor improvement, but still inferior sound quality for the person being called (whether they are on their own other cell or landline.)
BALMADOR: I bought mine at the AT&T corporate store on Main St. in White Plains NY. The sales kid, and contract, both promised a 30 day return period.
I am surprised that, of the (presumably) thousands of Titans out there, there are so few complaints about sound quality. Maybe I / we just have the rare problem ? ? ?
Any other insight from HTC, Google, or other web sites, etc.??? (I already checked WPCentral.com, and nothing more there . . .)
There are a few other problems, although not as major as this:
- Some phone numbers within given contacts (entered in outlook 10/ exchange 10) do not display on the the Titan. Seems to be 'Car', and others . . .
- Want access to the file storage space to set up directory structure for downloaded files (like the windows subdirectory structure & access), rather than just dump them into a single place managed by the system, without any identifiers other than the file name.
- The sync & skydrive of files seems random &/or flakey - We do not have the time to debug this.
- The HTC / AT&T issue standard documentation is superficial. (Also there is no WIKI, or no easy to access WIKI yet on XDA Developers, or I can't find it . . . Suggestions ? ? ?)
- Finally, Office Mobile seems generally flakey. For example, - Seems impossible to read & edit any file formats prior to office 2010, - Very difficult in Excel to highlight and drag a several cells, - can't figure out how to copy & paste reliably, etc., etc. . . .
Summary - I want to like & keep the Titan (another unit) so I am still inclined to try an exchange, or return the phone. Does anyone else have any further suggetions? (Maybe wait & try the Lumina 800 some day - What system will that be on, Verizon or AT&T ? ? ?)
Thanks, Art
not a rare problem
I was constantly told that I sounded "muffled" or "like I was underwater".
....I took my phone to be replaced for a new device....I guess I'll see how it goes.

I'm considering this as well as my titan is muffled on caller's end on about half of the calls to an unacceptable level.
Please update us on the results of a swap
Update re Sound Issue - Exchanged Unit : - )
Total fustration, so yesterday I went back to the AT&T corporate store (where I had upgraded from the Titl-2 to the Titan) and traded the Titan in for a new unit.
The trade in transaction took an hour ++, because the staff, although very friendly, cooperative and sincere, had no experience with the Titan (and I have a lot on my phone.) The store did not have or was missing the bluetooth dongle needed for content transfer, etc, etc, etc . . . But we got it done, thanks to my Exchange for Outlook, and e-mail for a few business photos, etc.
Anyhow, after 24 hours, it seems to be night and day on the sound issue - Extremely good, (except in very noisy environments); very loud both ends, better / tolerable connections in a few fringe areas where I had trouble with old Titl-2, No complaints on early test calls, etc, etc. I'll update y'all after several more days of experience . . .
So, Status Quo:
- My Titan is a very good phone (only) and decent electronic rolodex, with pretty good mapping / traffic / gps.
But:
- Lots of nagging ??software?? issues, some mentioned in prior post above. These problems seem like quality control programming bugs which should not have gotten through, and should be easy to fix. (Hope so as I really like this phone for my heavy business use!) More to follow.
HELP:
- How about a WIKI page for the Titan P139100 to organize the list of defects needing improvement, and most important, to supplement the superficial HTC / AT&T documentation, user guides? (lots of these problems may be mere lack of information & training for us users . . .)
I've tried to set up the WIKI page, with no luck. Maybe one of you with more experience can either get it started, or private message me with a little guidance . . .
Thanks
Arthur

I appreciate your feedback and it is encouraging to know that another handset might fix my issue (call quality) with the device. thanks! Think I might try to swap out for another unit when my local store gets more in
OTOH, I don't understand your transfer issues. Do you not have all of your photos and music synced with Zune? also do you have a live account where all of your contacts and calendar is saved?
I don't use Exchange server so maybe it's different but I walked into a store and swapped devices last week (Focus S) and stood there and reset (wiped out) my phone, typed my live account on the new device and walked out of there with all of my contacts calendars and email on the new phone instantly. plugged it into Zune when I got home and had photos and music back as well.
Went online to Windowsphone.com and clicked on all the apps I had previously installed and they too were put back on the phone
For everybody who having problem with the microphone.. I just spoke to HTC Hardware Department. They even not aware of this problem. Please call them and let them know. So at lease they will add this to the known issue list. Their phone # is: (866) 449-8358
For what it's worth, I just got my phone this past weekend. I've only had a few calls so far and no complaints from anyone. I have asked everyone I talked to if they could hear me okay and there was no problem.
I bought mine from a large retailer which hopefully means they go through a lot of Titans and I got a good one.
I did play a video from GoPro today and when I max'd the volume, it was distorted and had static. Haven't had the problem with other vid's so I am assuming it was the vid and not the speaker on the phone.
Decent phone. I was about to blow up when I realized that Outlook Sync was gone but after playing with it for a few hours, I was able to get the Windows Live connector to do it's thing for me. Not 100% happy but pretty close.
Same problem here
I have the same problem. I love the titan, but I have to fix this issue (or return the phone) for the sake of my relationship and work.
It seems as if the noise cancellation software is dumbing down the highs of my voice (it sounds like I am underwater). I haven't experience this problem when using Tango to video chat. I've also read that the problem doesn't exist while recording a video. Just a heads up, people have been posting about this issue in the wpcentral forums. I'm new to the forum, so I can't post links.
Here are the links to WPCentral forum:
http://forums.wpcentral.com/titan/184444.htm
http://forums.wpcentral.com/titan/184445.htm
I've also posted in this HTC forum:
http://community.htc.com/na/htc-forums/windows-phone/f/174/t/14751.aspx
Please put your comments as well. We need HTC's attention to this problem. Now we almost sure that it's not a mic problem (thanks to TANGO). Somehow dialer/phone software (noise cancellation or coding or any other filtering) and may be camera's part are not performing as needed on some units. And it should be fixed or patched.
Just a thought that might help with diagnosing the problem. I have a wired hands free headset (don't like any of the bluetooth devices from inexpensive to way over priced) and if you think it's the microphone or software for noise reduction is the problem, I bet you could try a wired headset and see it the trouble persists. If so, I would go get a replacement phone.
Just a thought.
Can someone who doesn't experiencing a "muffled" effect send me a private message with his phone # so we can make a couple test calls? That way we can really compare and make a better statement.
I've bought a titan for my wife, and had these same mic issues, she sounds muffled, recessed, underwater, got her a plantronics 975, and call quality went from bad, to terific.
Something is definately up with the mic/software on these things. I got the UK version from Clove.
I've since bought a second device for myself, and call quality is horrible, lots of chopping out, bad signal, bad reception. I was later told by my service provider, its a problem with their HSPA network, and the TITAN was not tested on it and may not be properly supported, i swithced off the 3g radio and sure enough all my problems went away, perfect call quality and reception, but no 4g? Sucks. They say they need to do patches on their network before the phone will work properly. But that seems to be a spereate issues, the mic stuff defiantely needs to be addressed. or we all use bluetooth!

Maybe I should factor in my location to the lack of problems with my phones audio quality. I live in the Dallas area, home of AT&T, and it's possible the network has been upgraded here and when I travel outside of this area, the quality will suffer as many of you have reported. This could be why some are not having troubles and others are.

¿bad microphone?, what can be done? (new info, possible corrupted firmware?)

Hi guys,
Sorry if this post is repeated or shouldn't be here, I searched and didn't find anything related.
I think this is my first post, so I'll introduce myself. I'm Antonio from Chile, Southamerica and I always look this forum and it has helped me first with my SGSII, then with mi Atrix 4G and now with my MoPho.
I just got my "new" MoPho from eBay and it's incredible, but somehow the microphone it's not working or working with a very low volume on calls, but now is the strange part: if I record voice with any voice recorder (ie: Easy Voice Recorder Free) or video with the camcorder, the voice sounds clear and fine.
At first thought that somehow, the gsm signal here could be inducing this, but when I borrowed my brother in law's phone (also a MoPho) it worked well without any issues.
I don't know if the previous owner did something to the phone. Besides doing a factory reset, I haven't done anything else.
I think that maybe the noise reduction could be somehow doing this because it's triggered on calls and not on recordings (my guess)
Do you have any other clues?
Thanks for your time, have a nice day!
Antonio.
UPDATE:
I just tried to call with headphones attached (not handsfree) and the voice was clear as water. Unplugging the headphones in the same call returns to the same problem. Could be this related to something that the previous owner did to the software?
I would like to flash the phone to stock, but reading, there's no 2.3.5 SBF for Photon, just for Electrify. I don't need CDMA since I'm in a GSM carrier so flashing the Electrify SBF and the peetr rom would work?
Thanks!
New update.
After doing a fresh install involving the usc sbf and now its working. Perhaps the previous owner modified the phone or messed up.
Thanks!!

Hi guys,
Sorry if this post is repeated or shouldn't be here, I searched and didn't find anything related.
I think this is my first post, so I'll introduce myself. I'm Antonio from Chile, Southamerica and I always look this forum and it has helped me first with my SGSII, then with mi Atrix 4G and now with my MoPho.
I just got my "new" MoPho from eBay and it's incredible, but somehow the microphone it's not working or working with a very low volume on calls, but now is the strange part: if I record voice with any voice recorder (ie: Easy Voice Recorder Free) or video with the camcorder, the voice sounds clear and fine.
At first thought that somehow, the gsm signal here could be inducing this, but when I borrowed my brother in law's phone (also a MoPho) it worked well without any issues.
I don't know if the previous owner did something to the phone. Besides doing a factory reset, I haven't done anything else.
I think that maybe the noise reduction could be somehow doing this because it's triggered on calls and not on recordings (my guess)
Do you have any other clues?
Thanks for your time, have a nice day!
Antonio.
UPDATE:
I just tried to call with headphones attached (not handsfree) and the voice was clear as water. Unplugging the headphones in the same call returns to the same problem. Could be this related to something that the previous owner did to the software?
I would like to flash the phone to stock, but reading, there's no 2.3.5 SBF for Photon, just for Electrify. I don't need CDMA since I'm in a GSM carrier so flashing the Electrify SBF and the peetr rom would work?
Thanks!

DONT FLASH ANYTHING FOR THE ELECTRIFY ON THE PHOTON THIS WILL LOCK YOUR PHONE UP AND REQUIRE ALOT OF WORK TO RECOVER..
Honestly, the mic is mounted directly to the board on the phone, it is NOT serviceable by anyone on a consumer level and Sprint for a FACT can not fix this in house and will constitue a complete replacement. If your not on sprint, you may want to re-lock and put on stock and call MOTOROLA direct and ask for a warrenty claim. The photon has 3 microphone recivers for noise cancelation and better quality but the bottom one is the one that pics up 99% of souns

Hi!
Thanks for your answer. About flashing something on 2.3.5, I don't mind having the bootloader locked since some P-Roms are enough. But the problems that arises is that the microphone is not bad. After updating to 2.3.5 (by mistake, didn't know all the problems that would bring me), all sounds on system lowered their volumes to, I don't know, 1/4 and that's what I am having right now, the microphone has a very low volume, that's why I thought that it was bad, the loudspeaker can be barely hear and the music sounds the same.
Looking at the web, there're a lot of similar cases after the 2.3.5 update.
There's any way to modify something (with sqlite, root explorer, etc) to fix this? Because besides the volume thing, this phone rocks
Thanks!
It is more merky waters when you have jumped into 2.3.5 with the lack of time for devs to gain access to this software. At this time we are still unable to gain unlocked status on the newest update.. you may want to attempt a factory reset to see if the issue was a bad install. You can also pull the update from xda and push a update to your phone you know is good.. not sure on the % effected with sound quality issues but if its a select set of devices that are having this problem attempt to re install the software would be your only choice until the update is unlocked and you have the ability to modify your complete system..

Voice echoing on other end of phone call?

EDIT: Read the other comments in this thread to see what I've tried and what hasn't worked. Thank you!
I love my Galaxy S5 so far, but currently it's sucking at being an actual phone. On the other end of the phone line, the people I've talked to have complained of the audio sort of cutting in and out like someone is interrupting me. This happens when I'm in quiet rooms alone, so I'm confused. At first I though it was the case on my phone (Supcase), but after replicating the problem for myself, that doesn't seem to be the case. So at this point I'm not really sure if my phone is possessed or if it's a hardware problem. For reference, I'm running XtreSoLite rom and I have a few Viper4Android audio things running. I'm not sure if that could be the problem. Anyway, if someone could help me solve this issue, I'd really appreciate it. Thank you!

It's certainly not normal. Not with stock firmware or custom ROMs like Phoenix. I have no idea if your custom ROM is a factor, bit it seems unlikely.
Possibly your problems are reflective of being in a location with a weak and tenuous signal strength. Generally speaking dropouts and feedback are data latency issues seen more with Voip and VoLTE calls. You don't have nearly enough information to do more than guess yet.. but I would make your audio app (Viper) to be the prime suspect.
See if you can exempt voice calls from Viper or temporarily uninstall it. Also find out if any background apps are using high CPU and in particular if any audio apps are set to high priority. Find out if you arwe using VoLTE. CPU (power saving) apps?
If you can't narrow it down, make a backup and then revert to 100% stock to rule out hardware issues. Then install apps one at a time, watching for the issue to return. You could also open a carrier support ticket to see if your account is misconfigured, using a low grade codec, etc.

Thank you for all of this! I'm having an unfortunate week because I'm actually away from home and have very limited internet access, so factory resetting my phone isn't currently an option. However, I did turn VoLTE off and I'll be wiping my cache because I read somewhere that might work. I'll also be watching my apps, but I'm not sure that's the problem. I generally have the same apps on all of the phones I use and this is the only phone people have said I sound bad on. And I don't think Viper is the culprit either because I've disabled it and nothing has changed. So hopefully turning off VoLTE works or simply wiping the cache does the trick. If not, I'll definitely do everything that you recommended because I want to avoid RMAing this device at all costs.
It seems that a factory reset solved the problem. I still have no idea what the problem was, though, but I'm happy it seems to be gone.
So the problem has returned. I factory reset once again and it hasn't done the trick. Everyone is describing it as an echo and telling me they can hear themselves echoing when they speak, although it sounds fine on my end. I don't know what else to do. I have:
Factory reset
Taken the sim out and put it back in
Changed APNs
I don't know what else I can do. Really hoping I don't have to RMA this device. Does anyone know how Samsung is with RMAs?
Bump
Still having this problem. I hope there's someone out there who knows how to fix it.
you ain't alone mine was fine for a while then after the new update it came back i call t-mobile.they put in a open repair tickets as others around my town also complain.my signal is always -114 to -119.they have heard it it when i call them.i get the echo or it brakes up or call turns into noise and then calls drop and they have to call me back on house phone they claim it is a tower/signal issue.??

I had this same issue as well. I could hear people jsut fine, but when they tried to talk to me, be it over tmo network or through wifi calling, they heard bad echoes and noise. I even did as you did; factory reset and it sorta worked. When it happened again, I cleared caches (the official fix from tmo 611) and that worked for a couple hours. Eventually, they told me to take it back to the store and get a replacement.
I believe it's a hardware issue related to the mic; here's why:
When I'm in my car and on bluetooth people on other end hear me just fine and crystal clear. When I used a bluetooth headset, same thing. As soon as I disconnect from BT and go to just the normal mic, echo pops in.
One thing you can do is call 611 and use the voice prompts. It was so bad on my end that the voice prompts picked up itself (well the echoes from the voice prompts). If you do and the voice prompt system routs you even when you don't say anything (it routes your call because of the echoes) then you definitely have a bad handset.
I was rooted, custom recovery, knox tripped and mailed my phone in. Nothing happened. But they did charge me $20 for a return/replacement fee. The new phone I got works no problem.
