[Q] Phone Doesn't Ring When Receiving A Call

Hey Everyone! So I'm having this problem where my phone will NOT ring or show that someone is even calling. The only way I found out that someone called me is when they text me asking why I didn't answer them. Well, my simple answer (that people are starting to not believe) is that my phone didn't even show that someone was calling... This wasn't so much an issue before because they could always text me if they needed to get a hold of me. But now after to applying to many places for a job, I kinda need it to ring. I also have another issue and that is that texts will not receive either. The only way I can get them is through Google Voice. This wasn't such a big deal to me but I would like to know if that can be fixed too. I have never had this issue until after I tried CM9. Since then I have tried many other ROMs to see if i still had this issue. I did.
The other ROMs I tried are:
MIUI v4
AOKP
Clean GB
Marcusant v3
MIUI Gingerbread
CM7
Legendary
What my current setup is:
ROM: AOKP
Android version: 4.0.3
Baseband Version: S700.0.5S.EI22
Kernel Version: [email protected] #6
Build Number: IML74K
Mod Version: aokp_epicmtd_build-28
Theme: NONE
PLEASE!!! ANY HELP IS APPRECIATED!

Odin back to stock EL30. Follow the procedure in the How to restore a semi-bricked Epic thread. Test it there. If it works root and flash, do not restore data.

I did this and (sorry for taking so long to get back to you but i wanted to make sure that it was happening often and not just once in a while) it worked for the phone ringing but the messaging, although im receiving them, they come late. sometimes VERY late like a whole day later. This is not cool and would really like to find a solution because i dont want to have to be stuck on stock :'( Oh yeah btw the ROM i flashed this time was AOKP. Thank you for the help!!

I believe late texts are a symptom of carrier network issues. It should clear up when the maintenance is finished.

I am having the same issue with the phone calls either coming in late or not at all. I test this by calling my number from a land line. It takes 4 - 5 rings before the phone will start ringing, if it rings at all. Most of the time, Google Voice answers for voicemail.
I remember back in the days when I had my Windows phone, there was something that we could do to have the phone poll the towers more often to make the phone ring faster. I know that this faster response to phone calls came at the expense of more battery usage. I wonder if some of the battery saving tweaks done by the ROM developers has had a negative effect on the phone calls coming in.
I have tried updating my PRL and whatever through EL30, then reflashing with out restoring any data. Still having the issue.
Thanks.

this same thing is happening to me and everyone else in my neighborhood that has sprint. Its one specific tower that's causing the issues. I know this because once I connect to a different tower the issue goes away. I contacted sprint about it and they said they would fix it when they do the network vision upgrades, which could be a ways away.

I kinda thought it was a problem with the network and so i called them and last time they sent me a airave and it didnt solve the problem. I still think its a problem with sprint overall and am planning on calling them.

I have the same exact problem. I have even had the phone replaced and it still does it. I only know when it happens because google voice logs the missed call. I have had it happen with a completely stock phone as well as rooted.
It is very frustrating because like you said, people don't believe you when you say that your phone did not ring.
They are actually going to switch my phone again. I know this is not going to fix the problem, but I will play the game!

[Q] Phone displays "Unknown Numer" when receiving calls

Ever since the update, my phone will sometimes not show a number from callers whos names and or numbers used to pop up. It just says "Unknown Caller/Number" even though before the update it would show their numbers. Anyone else experience this?
**EDIT**
Forgot to mention I'm fully stock.

My girlfriends phone also does this after the update and she is completely stock. I am rooted and on AOKP and haven't seen this yet.

Happening to me too, very annoying

I talked with tech support they made me do a full wipe, I did, and its still occurring. I just called in for a replacement, as I don't know what else it could be.

Probably by design by TMo so they can get you to subscribe to their caller ID app.

This has been happening to me also. Havent really looked into it.

mine did that and fixed it self on its own. weird thing is this happening to alot of people

Use whitepages caller id. It should remind the phone about caller id, and you can uninstall it later if you so choose

+1 on this. It happens to me at random. Sometimes my girlfriends number will show fine and others it will show as unknown. Not just cellphones but she has called me from her work phone and it does has happened the same thing. super annoying!

I've been seeing this alot lately also...I work in tech support and the times I have seen this something has been off on the back end we can see. I saw it was a known problem 2 weeks back but they've since removed it. Instead of moving a couple of things and click a button technically a "trouble ticket" needs to be filed so TMobile's eng team can track down the issue.
I've found no other workaround then calling in..sorry

I'm having the same problem. When I'm connected to wifi with wifi calling on, my caller ID works. But if I'm connected to the cell network with wifi turned off (or out of wifi range) then my caller ID almost never works. It's worked a few times when connected to the cell network but usually not. Have you guys called T-Mobile to let them know this is a widespread issue?

Hey guys to fix this issue, turn on Wi-Fi calling, place a call to the phone. Then change the settings on the Wi-Fi calling to use cellular network and place another call. After that it will stick until you flash another rom

Has nothing to do with wifi for me. Happens both on wifi and on cell.... Should we be sending in for a replacement? Also im on stock odin of ics. Not updated through kies. Very annoying issue i do not understand

Can't recive calls when WIFI calling enabled on SG2

WIFI calling enabled on SG2 won't receive calls
I've been flashing Roms for about three years now. I travel over seas quiet a bit and wifi calling is have been very helpful. But lately I've been having problems when I'm on any ICS roms. I don't know if it's just me, because looks like nobody else is having same issue, but I can't receive phone calls when wifi calling is enabled. It goes strait to voice messaging. I can make phone calls, but can't receive them. I have no problems with WIFI calling when running Gingerbread roms. Please help!

Might wanna take it up to tmobile if you confident you are following the ROM installing procedure.
How about go back to GB and see if you still have the issue

Thanks for the reply!
That's the thing, WIFI-calling is working just fine on ANY of GB ROMs (I'm running Darkside Digital Warfare v2.7 now). It's when I'm on ICS ROMs and WIFI-Calling is active incoming calls not going through, they are going to voice mail without one ring from the caller (it's like phone is off). But I can make phone calls no problem. And trust me I've tried all the new ICS ROMs that came out lately. And I do follow installing instructions very carefully.

Do you have the beats audio mod installed? I figured out with a few other people that it does cause an incoming call issue. And i know that wi fi calling is hit or miss on ICS

oh man. i just realized im having the same problem. i just didnt think anyone was calling me.

I called T-Mobile about this today, because none of my phones (S2, Blaze, Double play) would receive calls over WiFi. Ever since I called it's been working. Maybe it was a system update on the T-Mobile end?

But I can receive calls (wifi active) on all the GB ROMs I've tried. It's the ICS ROMs I'm having problem with... But thanks for the advice, I'll try calling T-mobile tomorrow.

Strange Calling Problem/Busy Signal

I've recently been having issues when calling certain numbers that my phone either starts ringing a few times then I get a busy signal or sometimes just a busy signl right away.
I know I'm not blocked from these numbers because one of the numbers is my gf and the other one of my close friends.
Now both my gf and friend have Sprint as well as myself. However, I can use my gf's phone to calll my number and she doesn't get a busy signal. And, if I call her phone from say a Verizon phone it rings normally.
This started happening very recently right before I upgraded to JB. I'm stock rooted.
Any ideas? I am thinking of calling Sprint to see if something is going on on there end.

Have you made any progress on this?
I have an EVO 4G LTE,, my wife has an EVO 3D - both stock and unrooted.
I can call anybody but her - I get a busy signal. -= maybe for the last 4 days, (Hurricane Sandy related?)
Anyone else can call her without a problem
I can call anyone else without a problem.
I can text her just fine.
On her phone, I blocked my number from calling her - when I did that, I went straight to her voicemail. When I unblocked it, back to the busy signal.
I deleted my contact from her phone and Google account - no change
I spent 20 min on phone with Sprint Tech support- we restarted both phones, reset voice services on both phones, pulled her battery - none of this did anything.
The rep told me to either hard reset her phone, or to go to a store with both phones.
So, I hard reset her phone. I logged into her google account and did nothing else.
I called her from my home phone - call went through. I called her from my EVO - call went through!!!
So, feeling cocky, I saved my number to her phone as a new contact. I called her again - BUSY SIGNAL.
I deleted myself from her contacts again - no change
I have hard reset her phone twice more tonight - both times I just got the busy signal.
Anybody else have any thoughts?

Im having the same issues when I call my wife's phone. I have Google Voice. Is that the problem?

Yes, had the exact same issue on my sgs2. Thought it was sprint, but after disabling Google voice the issue was resolved. I added it back about a month later with no issues.

Had this problem as well. Originally had evolte, sprint kept telling me it was network related. After two weeks I finally went to a corporate store and they ported my number to a different phone and called the numbers that where getting busy signals, and it worked. So they said it was my phone not the network. Sprint wanted to give me another evo, this would be my fourth evo, I decli ed and said I wanted a different phone, after much arguing sprint agreed to let me switch to the gs3. Came back two days later to pick up phone, after activating the phone I called the same numbers and STILL COULD NOT CALL THEM. Wtf. So they blamed google voice and said to try deleting it, if that did not work then call cust. Service. Deleting google voice did not work. So I called cust. Service they said after explaning what was going on cust.u Service said this was a known issue and did not know what was causing it and had no estimate when it would be fixed. She asked for the numbers that I got busy signals on and then offered a fourty dollar credit a month for four months. Wierd. Today I could call one of the numbers and it went thru. Havent checked the rest yet.

It is not google voice. Sprints network is the problem. They are aware of this. If you have problems call them and give them the numbers you cant call. My problem seemed to be fixed on sunday.

Sorry for the delayed response. I didn't see much going on with this thread for a while so I thought I was just having a isolated issue.
Turns out the issue is a common Google Voice issue atleast if you have integrated your Sprint and Google Voice number into one.
I got rid of my Google Voice integration and am now back to the "lite" version where you have your regular Sprint number and a separate Google Voice number and the problem has totally stopped.
The reason I say it's a common issue is because people are posting about this in the official Google Voice support forums.
I wish I would have checked there first because it would have saved me a lot aggravation.
Anyway, try un-integrating Google Voice and see if that helps.

Using Google light and separating the numbers did not work for me I even uninstalled Google Voice completely and it did not work it may be true that Google Voice is having issues as well but the current issue is a network issue at least it was for me as a previous poster said mine started working on Sunday at least I got a Samsung Galaxy 3 and a 40 dollar credit a month for 4 months out of the deal

Are you using wifi calling? There's been known issues with people not being heard either from caller to receiver or receiver to caller.

NO sir, I tried switching on and off wifi calling and airplane mode. pullled battery, and master reset. Tmo said it was a network issue.
So no one is having problems not hearing the caller on a incoming call????
