S4 no sound - Galaxy S 4 Q&A, Help & Troubleshooting

okay so im going to start from scratch, my s4 has randomly started giving me no sound, ive had it tested and all my components are good so it has to be software.
i have flashed multiple roms, modems and wifi fix
but im willing to give anything a go just let me know!
beginning to really stress me out! i have included a pic of my current setup, cheers and thanks for the help!

does no one have a clue on this?
i was thinking maybe wait for the lollipop update and it may sort itself out?
or flash another stock rom and gsm modem only?
i have already triggered knox so not really worried about the method, anything would be of great help!

Im not sure what's goin on . It might be a Hardware issue? Try pulling the battery out / factory reset/ wipe data in recovery . If its still.doing the same issue . Wait And Let see what firmware @Joku1981 will give you . It might fix this problem . Anyways Goodnite for now .

Yes sorry to disturb you, I've had my device tested it's been going on that long it all came back okay :/ thanks a lot it's definitely improved!

factory reset no luck, cache wipe no luck, battery pull no luck, i was thinking try flash a stock rom? have a feeling ive got a few duff ones, any recomendations?

Whether it helps or not apart from no sound, videos play in slow motion, battery when unplugged from fully charge drops to around 80% and sometimes when the phone is booted it boots with no signal and a black top bar, before restarting again normally

If your network was unstable you wouldnt be able to get any signal at all but it wouldnt make your phone reboot. Have you tried factory reseting your phone??

Dude you ain't the only one. The MF9 update has been a major pain the @$$ for a lottt of people. I wonder if Sprint is working on a new update. Hopefully push it out before the end of September. Although I am really liking MF9, I am probably in the minority. My device is smooth as hell and great battery life. Just yesterday I went 20hrs with 3hrs of on screen time!
Im having a similar problem. Random reboots when data is connected. I first thought it was the connection in my area that was causing the problem to (NV just started in Cleveland) until I encountered reboots while on WiFi. It doesn't matter what app I'm using as long is it uses the internet connection my phone may freeze vibrate two to three times then reboot. I even reapplied the MF9 update and the same problem exist.
I'm completely stock!
Thank You Based God!

We must be lucky. I keep reading about all these issues, but MF9 had been awesome for me. Not a single problem, and definitely much better than MDL.

Check your source for the MF9 kernel you have and try downloading and installing a different one.

Low Frequency Beep During Calls

Is anyone else having any issues with the speaker when they are making calls on there S5? Whenever I'm talking with someone on the phone every 4 or 5 seconds I hear a low frequency beep the lasts about 1.5-2 seconds and then it goes away... After another 4 or 5 seconds it does it again. I really hope it's a software issue as I don't want to send my new phone in for a repair already.

I will have to try contacting Samsung about the problem. I will let you know what they say. I doubt target would do a straight exchange on the device.

Try disabling CARRIER IQ or removing it if you are rooted and then check for the beep afterwards see if it's gone and let us know what your results.

Well if you are not rooted go into settings then backup and reset and then collect diagnostics and uncheck it and this theoretically turns it off, now if you are rooted you can install root explorer open it up make sure that you are mounted as rw then search the root directory for carrier iq and delete it this removes it from the device.

The first thing I did was disable carrier iq when I got my s5 and after seeing this post I made a call to check for the noise and I dont hear it so maybe the carrier iq thing is the ticket.

Sorry.. but what exactly do you mean by "disable carrier iq"? Cause I'm a real newbie when it comes to doing administrative stuff to your phone...
I also thought that it maybe could be worth Factory reseting your phone? But I've got a lot of settings and stuff that I don't want to do again.. but if it's really needed I'll do it.

I tried that. But I'm afraid it did not work.. The annoying sound is still active. But the weird thing is that sometimes and on some calls it's occures very often and being annoying as hell.. and then again it can be off for like another call that lasts 30min+.. I hope that it's the phones own speaker that's broken or something..
Haha I hope you're wrong.. I really hope it's related to carrier iq

Yeah. I tried all of them regular settings. Minutebeep, noise reduction etc.. The sound kept going. But I also noticed that when I connected my headphones and talked trough them that there was no annoying sound.. so I guess it's something with the phones own speaker.
But I put the phone on service today after 11 days of usage... lol. Hope they'll fix it!
I don't hear the issue when I'm using bluetooth in my car either. That being said I'm pretty sure it's a issue with the speaker in the phone. Time to swap it out for another device!

So Undergrad.. are you really swapping it in for another phone? They actually gave me that option.. but I kind of said no.. I just wanted my phone to work 100%.. maybe it was a stupid choice..

Target is ordering me a new device and hopefully it resolves the issue. It certainly appears that the issue is with the speaker.

Phone keeps turning off

Hi, when I'm trying to multitask on my i9505 it turns itself off and goes into bootloop, and will only turn on properly if I have it plugged in.. When it does not it will show only 1 or 2% off battery left even if it was almost full before random reboot occurred.. In using custom Rom slim l.p.. I'd it likely to be a battery problem or rom problem given my troubles above? Just purchased a new battery in any case but I'd like to move back to official sammy software in any case...do I need to do this via odin?I don't mind about root any longer, I don't use apps that require this anyway
I'd also appreciate help finding new sammy firmware, I can barely keep my phone on long enough to search for it!

Try to change your battery and see whether it's still overheats.
I wanted to do that really, but i wanted someone else to tell me so i would not be a wierdo, you really think that would work?

I have 2 batteries. One gave me overheats, even though the battery itself is not bulged.
One totally no issues at all.
Same phone, same ROM, same setup, same etc.
You can give it a try. But then again, I might be wrong.
Technical issues can arises from a lot of factors anyway.
I will try, thank you so much for your reply

Try the old modem, the one you didn't have any issues. Otherwise it's samsung's crappy update.
Can i go back to that modem?? No risk?? I changed the csc, changed the sim, changed the carrier, changed 3 batteries... still blowing fire, 80c om the cpu... many times when i use my data plan

I may also be related to the lollipop update. Since you did mention that it didn't happen on kitkat. It only started happening since moving to lollipop. So it may also be the update. Go back to kitkat or change to a custom rom and see if it helps.
I tried all, just all custom roms with lolli
