Phone modem issues - Captivate Q&A, Help & Troubleshooting

So it seems every month or so my phone part of the phone starts acting up... I hear weird ailen type sounds or a call will just hear me echo until the person calls again. It seems a new modem flash.then fixes it for.a month. I've experienced this with two modems now. Does att systems catch on to em then cause problems? Or why do I have issues after awhile, swap it then its fine?

Modems are kinda a pain in the @ss. You can't suggest someone to use a specefic one cause they act up completly different from phone to phone and the area you're in also makes a really big difference.
I've personnaly always been using JK4, I tried a couple others but they weren't bringing me the same performance/stability.
There's a thread on them. If you do a little search, I'm sure you will find it

I get what your saying, but do they have a lifespan or something? Why do different ones randomly act up after awhile? Is that i9000 modem?

Delay in receiving texts

I am finding that I am getting texts which were sent couple of days ago.having said that, I am not certain that this is not the case before I rooted & apply lag fix to my galaxy s? Is anyone else experiencing the same problem?

That has to do with your Sim and your provider... had that same issue with a dumb phone at one time.
Thanks for your reply, but I don't think it's anything to do with my sim/provider as my brother has an unrooted galaxy s as well rough on the same network & he has no such problem.he also has the same jf5 firmware.

You can't tell, your telco sms server may be screw up and hold your particular sms, just like email. Did that happen all the time or once a blue moon?

It happens randomly but more often recently than ever. All my family members who have cellphones are on the same cell phone provider but none of them are experiencing the same problem, I am therefore convinced it's to do with my phone somehow...

lots of dropped calls / weak signal on stock 2.2

So my gf just got a new captivate, and its running 2.2 and she says dropping a ton of calls, and that she has weak signal alot and so on....
my question is should I swap the modem ( shes on stock) from the KB1 or what ever to like the JH3 ?
OR should I return it and get a new one?
What are the chances the phone is hardware defective vs modem troubles?
They tried to fix problems with 2.2 and they just created more. Try switching the modem. I havent been messing with stuff lately, Ive been pulling my hair out with at&t's return center. Try KP1. But make sure the phone is rooted before you do this.

JK4**** damn autocorrect.

Thanks. I think i had good luck with JK4/JK3
people say modems work better in some areas then others, is there a "modem map" or something that says this works better here and that better there, ect?
No haha i guess people are too lazy to coordinate a country wide effort for modems lol.

Missing sms

Recently my phone isn't able to receive some of the sms text, not all but some, I wiped data/cache and reinstall cm7 but the problem continues? Does anyone know what's wrong?

Do you have auto-retrieve enabled? Sounds dumb, but sometimes the most simple things go right above our heads.
Also, it would be of great help if you provided more information. What sms app you are using, carrier, modem, etc.
Just made sure that auto retrieve is on. I am on at&t And the radio band is T959tljl3. I'm using cm7 stable mod. It never happened before and it only started recently. And I'm not using any sms app Thanks for the help btw

Do you get a lot of text messages? One of our users on the Legend thread had the same issue. We suggested lowering the amount of messages from 100 to 50 before they are deleted. The user reported back that the issue was resolved after doing so. Not sure if cm works the same but worth a shot..
Yes I do, I will give it a shot, the weird thing is that it never happened before.
Thanks for the advice though

I'm not sure if your are referring to the modem, I believe baseband refers to the modem. Regardless, can anyone confirm that modem works on the captivate? I don't know why, but I think that modem is for the Vibrant.

Yeah sorry I meant baseband

Get on over to the "soggycashew.weebly" website for modem dance and also find which modem is best for your area via map location. I just did the dance again the other night and fixed my phone. I'm using the T959tljl3 - radio-cm7-ics-captivate-tljl3-signed.zip download/modem. Works perfect up in Ottawa.

Continued phone issues

How many times can one return a phone for replacement for the same issue? At some point can I request a different device? I'm on my second "one" and it has the same connectivity issues my first one had. Can I at some point ask for a different phone.

You sure its the phone and not issues with the network ? Where I work, we only allow a total of 3 (original, swap, and another swap)
Sent from my HTC ONE from Tapatalk 2
It's already been replaced once. Where I live I have pretty good service, but there are times when I drop my connection while I have a good connection. What happens after the third replacement?

You haven't described the type of issue that you're having. Remember, the bars only indicate voice signal strength.

3 swaps within 1 year. This would be through Asurion. At the Sprint store they will swap it 3 times before offering you a comparable model. If you want to keep the same phone then they can swap it as many times, in store, as you would like.

I can be using various apps like poker F.B or even the browser. Take the internet for instance. I can be using it and at any time it will loose connection. Same with playing poker. While I usually get connected within a minute, it's still annoying. I can't tell that I have good connection cause when it is on it loads pages fairly quick.

I get that a lot on my Note 2. Usually its the phone switching back and forth from ehrpd to 1xrtt. Either your towers are being worked on or are over capacity like mine.. Worst data experience ever. After 10yrs I might bite the bullet and switch carriers, can't take it any longer..

Until your area is complete or a Radio update is released your phone will continue to act like this..Only way I could make mine stable was to run it in CDMA mode only and completely ignore 4G until more towers fill the gaps.

I get the same issue and have come to find a workaround that fixes it. This only works for 3G, but if you switch your network settings from LTE/CDMA to CDMA only you won't have any issues. I never get the issues that you explain while on 4G, but I constantly get them on 3G. Get that fix a try and let me know if it works :good:
Go into settings them power and turn off data sleep.

Call sprint. Have them verify your SIM ID and UICC ID under settings/about/Phone Identity. Make sure they have the same number on your account as the phone. They may argue with you that the number doesn't matter accept for International but make them check anyways. If you have 4G in your area it will matter.....or even if its just Network Vision. Just keep pressing them to verify. If they are different have them connect you to activation's and have them fix it.

Hello numerous times

Howdy
When I answer my ONE, I gotta say hello at least twice, sometimes three times before the caller can hear me.
Anyone have any thoughts about this. I am running D3RP 1.ROM
After reading this I realized it happens to me too. Running stock rooted.

I am willing to bet you are all using google voice. This is a typical symptom of google voice users. From my experience it has to do with voice settings, but it might not be the case. It depends on a combination of things.
Seems as though it is probably happening to all of us on 1.31 being the first update that has HD Voice which, I am guessing, is why we have that issue... Just have to get it working flawlessly now type thing since it is finally here

A lot of evo lte users had the same issue. It seems to be a semicommon HTC issues. Most likely due to HD voice and/or two mics. Something isn't kicking in properly. We've been able to fix the issue with a reset. But there have been rare cases that didn't solve the issue so had the phone replaced. But a reset usually fixed the issue. Also having lte on caused it for some. Switching it to just cdma fixed it for some. Luckily we aren't having data issues. A lot if evo lte owners can't even use the data and has serious call issues when lte/cdma is turned on. Hope this helps
Edit: I should add that you should try turning lte off first before attempting anything else lol. That is a more widespread issue right now
