Incoming call issues

Very often my Optimus 2X phone appears as powered off to people calling me especially those I have put into my phonebook. No outcoming call issues. I have the recent update of stock rom in Greece. I have tried factory reset, selected 3G or 2G Network, but the result is the same. Any solution?

had same issue several times. was listening music on headphones. waited for call - did not get any. so i tried to call back - phone was very slow and i was not able to make a call. so i restarted phone. after that i was able to call. people wanted to call me before said that my phone was turned of.
i was on cm7 nightly that time. this problem occurs rarely for me.

In call sound problem

I have in call sound problems.
When I reboot I can sometimes place one call without problems for as long as I want.
Other calls after that I have no sound, can't hear the call tone and other parties can't hear me.
Also incoming calls, i hear the phone ring but when i answer the other party can't hear me and i can't hear the other party.
The settings for sounds in the accessibility menu and noise reduction etc were off and stayed off. (other forum tips)
I also tried numerous factory resets with no avail
Can someone give me a hint how to fix it?
I have stock 4.2.2 International version of the S4 Active.
Baseband I9295XXUBMK2
Build JDQ39.I9295XXUBMK2
Kernel 3.4.0-2015525

Headset
I tried a different option. I can call with my bluetooth headset.
When i switch to speaker the in call sound drops. giong back to headset will not activate in call sound.

Same Here
The same happens to me. Only the bluetooth option works every time. I have tried several firmware and kernel versions and nothing has changed.
There is a workaround that I could find but it is totally impractical: http://forum.xda-developers.com/showthread.php?t=2371034
In forums for models / ROMs with a lot more users than this one (Nexus / CM) people with 4.2.2-based firmware versions there are many posts describing what could seems to be the exact same problem, which they have been able to fix via baseband updates or custom patches, but that does not really seems to be an option for the S4 Active...

I to have the same problem but im on a I537! This is the second replacement device from ATT! Have noticed i can call out fine when someone calls no audio nor can they hear me,call back and it works fine.Also have noticed when a call is incoming or outgoing LTE will switch to 4G.

Same problem with my SGS4A. I was on i9295XXUBMK2, tried to update using the phone update option, which rendered my phone unusable. Flashed new stock ROM i9295XXUBMK3, now I can use the phone, although sound problem persists.
Making a call: reboot, call
Receiving a call: answer, hang-up, reboot, call back
Anyone with 4.3 that has this problem on SGS3, SGS4 or SGS4A?
Edit 21.8.2014
I had the speaker changed last week and so far no problems. I am slowly getting confident that I can rely on S4A as a phone also, not just tiny surf tablet.

I have same phone, never got this pb. However I got some SD card issues after updating to KitKat...

Partial solution... for me at least
Hi guys ,
having same issue, disabling 4G option solves my problem. But it-s impractic cause I want to use the 4g... in a huawei phone I solved same issue by disabling an option of "mobile data always on"
Don't know how it's related...

Same issue for me. I made lots of research with no results. Nobody knows...

same problem here with no solution yet

same problem with in call and out call .... searched a lot about solution and no solution yet

I had a similar issue with bluetooth calls. First call would be fine, but after that I couldn't hear the other person on the line and they couldn't hear me. It turned out to be some kind of incompatibility with the Google "OK Google" detection with Galaxy S4-based phones. If I disabled it from detecting "From any screen", this seemed to correct the problem. However the setting might return on application updates. I would recommend trying that and see if it makes a difference. If it's not that, then I don't really know how to help you. I moved on from that phone over a year ago and have been happier ever since.

Having problems reciving calls.

I have a problem with incoming calls, sometimes when try to call me it say's my phone is turned off, when it's not (I can call out without any problems)
Signal is fine and i can call out but people have problems calling me.
I don't get it.

It may not related to the hardware nor software of your phone. I've been facing this problem since I was on my old Sony Ericsson K770i. People can't reach as if my phone was turned off. However it happens occasionally. Yes, until today, same things happen but only occasionally. The only thing I can blame is my service provider.
But odds do happen. It might have something to do with your device. Does it happen everywhere you go?

[Q] Silence when answering phone call

I have VoLTE and Wi-Fi Calling turned off. Sometimes when I answer an incoming call quickly (actually that doesn't matter), I just get silence and I can't hear the caller and they can't hear me. I have to hang up and try again; Anyone else encounter this?
Update: I think I narrowed it down. Apparently the first call I receive after rebooting my phone always fails (unless I've made an outgoing call first). Subsequent calls work fine until my phone is powered down or rebooted, then the 1st incoming call fails again. I can reproduce this 100% of the time.

I've had this happen a couple times, funny thing is I've had it happen on my S4 and S5 as well.. Im starting to think its Tmo's network.

It might be a glitch with T-Mobile's network, but I haven't encountered it on previous devices. For example, I just switched from the Nexus 5 and never had a problem with voice calls.

I've had this happen a few times also with my S6. Never happened before, and I've been with T-Mobile for over 2 years.

This only happens for me occasionally if one of the callers is on Wifi calling, but it's happened with every phone (not just the S6) so it's definitely a network issue

I found this related to the S4, http://thedroidguy.com/2013/06/gala...ting-incoming-calls-66029#jMqaFVvIYCDRQHse.97. I've disabled the mute function in motions and gestures. We'll see if that works.

Been with Tmo for 5 years now and I have had this happen on previous devices.. could be the area I am... lol, I also notice a delay when making a call out which I believe is the network

Never had this problem on S4, but since getting the S6 this problem has been bugging me. Very frustrating.

Ear-speaker sounds high pitched in calls issue

Hello . I am long time follower of your forums but now i decide to make an account cause I got some troubles with my Note 5 .
I have a Note 5 model n920-c (Arab Emirates) but I live in Romania .My problem is that from time to time when I make or receive a call, the in-call sound from my ear-speaker is high-pitched almost screetching(but still manageable and understandable) ....
If I put the call on speaker the sound is normal...
This is happening to me only 2-3 times a day and it seems to happen only with calls made in my network(ORANGE RO)...In every other calls(whatsapp , facebook , skype) the ear-speaker sound levels are just normal...
Just to mention I also fave HD voice active for my network calls...
Its is a network provider issues ?Is it a hardware issues?Did some of you experienced such thing on your unit?
Happy to be a part of your forum from now on ! Looking forward for answers

Not even a tought? :crying:

Same problem here. Also n920c and also on orange ro. Problem apear when i call on orange and vodafone. And another problem today: while on lte i have full signal, i can call without problems but when someone tries to call me enter the voicemail. Switching to 3g solves the problem. Switching back to lte the problem reapears. Some ideas anyone? Thanks
