[Q] Call Disconnected - Any Advice?

I've been seeing this problem for a few weeks now, with several different ROMs, including the original rooted stock ROM now. In nearly all of my recent calls, I get disconnected one or more times with the message "Call disconnected" and a "Dismiss" button. I'm thinking that this is because of my EVO and not the other side, since usually if they accidentally hang up or something the call just ends without a message box. As far as I can tell, I have good reception (at least according to the bars), and this is happening at home, where I've not had the problem before.
Does anyone know what could be causing this? My wife's EVO is not rooted, and she does not seem to be having this problem. But then again, I've not had the problem until fairly recently either. I've tried updating my profile and PRL with each new ROM, but it doesn't seem to have made a difference. Anyone have any suggestions as to how to stop this from happening?

Go into the settings menu andbupdate both your PRL and your profile. That *should* help with reception related issues.

Unfortunately, I've tried both of those things. I just did some testing today, and it seems that my phone is unable to stay connected during a phone call for more than five minutes before disconnecting, even if I don't touch the phone and just leave it sitting on a table.
Any other ideas? As far as I know, I haven't ever flashed my radio away from its default (2.15.00.11.19), and I'm currently using the leaked stock gingerbread ROM (build number 4.12.651.1 CL41771 release-keys and kernel 2.6.35.10-gaa602b7 [email protected] #1).
Maybe it's time to unroot and contact Sprint?

You can try downgrading from 2.15.00.11.19 to 2.15.00.09.01. You can download it from http://www.mediafire.com/file/jyedjkp1bm5amwm/EVO_Radio_2.15.00.09.01.zip
Afterwards, go into recovery, wipe cache & dalvik cache then flash the zip. You will be taken to the radio update screen and appear to hang. don't worry or get impatient. After it is finished, you will reboot into recovery and see the words "clearing cache" at the top of the screen. Simply select reboot and then you will boot to your homescreen. The initial boot will take a tad longer since it will be rebuilding the dalvik.

Hmm... I'm hesitant to downgrade my radio because my wife has an EVO with the same radio version number and hers doesn't have this problem. Granted, she is not rooted...

I understand. I've downgraded and upgraded everything several times for testing purposes and troubleshooting purposes and have never had a problem. The only hing about flashing radios is patience and not to pull the battery. Anyway, you can always call Sprint and see if they can troubleshoot it for you from their end.

I would contact sprint @ 877-809-6696 (advanced tech supp). Ask them to push a full reprovision to your device. See if that helps any. I was having issues when when on the airave, I was unable to receive incoming calls. This corrected it. I did try all the other steps listed above without any success.

This is interesting. I unrooted to test things out before calling Sprint, and the problem went away. I was able to stay connected for an hour (where before I couldn't last longer than 10-15 minutes). Yay, fixed, right? So, I rooted again and didn't install any ROMs or anything, just rooted, and the problem came back.
So, I have a solution, but I don't like it very much because it means I need to stay unrooted. Anyone have any idea why simply rooting the phone with Unrevoked 3 (and doing nothing else) could cause calls to disconnect? I'd love to be able to root again, but I can't deal with a phone that randomly disconnects all the time.

I am interested in this as well as I am rooted using unrevoked and get disconnected as well. I do find that it mainly happens though talking to people who have service on AT&T.. Quite wierd. All I hear is a beep then disconnected. This happens when I first place a call and it rings once or twice then beep, disconnected...

This may not be related to rooting. I'm still communicating with Sprint about this issue, and along they way they replaced my phone entirely, and the problem is still happening. Very frustrating, but it makes it very clear that the problem actually has nothing to do with the hardware. I'm pretty sure there is some network configuration problem on their end now. I'm waiting to root my new phone until this issue has been resolved. It is killing me!

So whats the final call on this ..?
Is it Rooting , Is it network .. i am too getting psyche with this .

I'm pretty sure it is not rooting. But I don't yet know for certain what it is. Sprint thought there might be something wrong with the antenna on my phone, but they had already replaced the phone, so I think that is unlikely. They gave me a femtocell range extender to use in my house. Basically, I plug it into my broadband connection, and it is like having a mini cell tower in my house, giving me a very strong connection. Sure enough, when connected to that, I haven't had any calls drop. However, my phone still sometimes doesn't connect to the femtocell and instead connects to some other tower for some reason. My wife's phone doesn't do this, so I still think there is something wrong with my phone. I may contact Sprint again about this. ...sigh...

What is your area some area evo don't work properly like on rahim yar khan in this time connection don't work properly some signal drop and some time up i sure after few day signal work properly then problems will be solve.

My phone EVO is doing this now as well. Has anyone heard/read a solution?

I am having the same issue, out of the blue. No problems up until a few days ago. I'm wondering if it is maybe an issue with a certain version of the Evo. I have a version 002. Thoughts?

Greg_99 any progress on what might be causing this issue?

[Q] Wifi loses connectivity after period of inactivity

Hello,
I've searched around the Epic 4G Touch forums as best I could, but sadly I couldn't find anything that was exactly this problem (although I found some interesting articles about wifi sleep time but they don't seem to apply). I'm experiencing an annoying issue where I can connect Wifi just fine, but if the phone is left for a small period of time (~10 minutes), wifi appears as if it's still connected, however it cannot send/receive data. When this happens, the wifi status says it's "connected", but there is no data connection. The only way to to get the data back is to turn off wifi, wait for 3/4G connection to initialize, then turn Wifi back on to refresh it...then it's fine again until I set the phone down again.
I had this problem on stock EL29, so I rooted and flashed Phantom Blazer ROM (very cool ROM, but I'm still experiencing the same issue). After reading the threads on here about wifi sleep times (apparently they're backwards with ICS roms), I've experimented with every setting, yet I still have the same issue--Wifi is fine as long as I'm using the phone, I set it down, after about 10 minutes pick it back up, says it's still connected, but no data connection.
has anybody experienced this problem with this phone? I'm about to unroot my phone/go back to factory so I can take it in to a Sprint store, the problem is they (trying not to be offensive) don't seem to know very much about this device. I thought I'd ask the pros before I return it, get an iPhone, and have to eat my words about how cool Android is vs. iPhone in front of all my friends. I'm hoping there's a reliable ROM or app that can resolve this vs. having to just replace the device!
Thanks for your help!

I'm not the only one
I'm not the only one with this problem:
edit: I can't post links to androidforums.com or anywhere else, but this same problem is all over the interwebs and nobody has a solution.
I'm sure it's not my router as my ASUS tablet/laptops/girlfriend's iPhone experiences no connectivity problems. I'm thinking this is a hardware problem with some of these devices. I will unroot/reset to factory tonight and let you know what happens.

What channel is your router on? And what type is it A/B/G/N?

This is s known TW ICS bug, most likely kernel related. Almost everyone is having this issue and there is no fix until Samsung decides to repair it. There are quite a few posts similar to this one. If you're using XDA's search function, it's not very good. Try using Google next time and search XDA that way.

Hey guys, thanks for the response. Just before I unrooted/reset to factory I tried one last solution--download an app called "Wifi Fixer". It has resolved a lot of these problems. It's not 100%, but after testing it for a day so far, I've only had to manually refresh the connection once or twice. It's a lot better, even liveable, and I won't be resetting to factory afterall, at least not until Samsung provides an update. So if anyone is having the same problem, try Wifi Fixer, hopefully it gives you a similar level of success...I'm not super happy about having to run another background process all the time, but it doesn't seem to affect battery, and the fix it provides is worth it to me.
Cheers!

Huh - a couple of things. Noticed this problem crept back in FF18 and didn't know why until I went back and checked the wpa_supplicant.conf that I'm using. The line ap_scan=2 was missing; after adding it back in the signal strength is back to full and stable.
I'll bump the thread but it appears the config changes here still hold after all:
http://forum.xda-developers.com/showthread.php?t=1569348
This should also avoid having the WiFi fixer there as you can specify the country in wpa_supplicant.conf manually.

Thanks for looking in to this! A couple questions from a noob like me though:
When you say the problem crept back in FF18 ... what does that mean? Is that something that exists in the "stock" version of the Epic 4G touch from Sprint?
The manual config file tweaks you're describing ... is that something I can perform myself?
Basically I'm wondering if it's "safe" to revert to stock in order to get consistent wifi signal, or if it's something I'm experiencing because of the ROM I'm using.
Thanks!

Toro Network Drops, 4.2.2 and 4.3

Hey guys - my VZW Gnex (it's a refurb to replace my old one with a bad screen) has been having excessive network dropouts lately. When I boot the phone, it doesn't acquire signal for over a minute, when I place a call I lose signal afterwards, and data drops out randomly. The device will say it's connected (blue bars), although I cannot use the internet. Also, it'll randomly loose cellular connectivity, although indicate that it has signal. I'll go to send a text and it'll immediately have send errors, and I am unable to make or receive calls, even though it shows I have signal. To fix, a reboot is always necessary. This has happened on 4.3 (crDroid) and 4.2.2 (CM 10.1.3 stable). It has happened across all the different radios, 4.0.4 and up, and across several different kernels. Does anyone have suggestions, the phone isn't really usable if people can't get in touch and I'm unaware that they can't.
EDIT: When I go into the phone info menu *#*#4636*#*# when the radio has no data, it says preferred network is "unknown." If I change it, the setting immediately goes back to unknown.

U might need to go through the insurance and get another one.

This is a known issue with 4.3 ROMs. I'm not sure about 4.2.2. It looks like CM 10.2 may have a fix for it in the next nightly. One known fix is to edit build.prop to include
ro.telepohny.default_cdma_sub=0
Thank has worked for me.

[Q] Signal indicator issue on unlocked and rooted AT&T S3

I have a very weird problem on my S3 and I have looked everywhere and I can't figure out what's wrong.
I have a stock unrooted S3 on 4.4.2. Recently I took the phone overseas and had it unlocked, I don't know quite how the person unlocked it, but when I got it back it was having a lot of problems. All my Data was wiped, but still unrooted but showing many errors. I was having an error every time I opened my contacts saying android.process.acore has stopped. I was also having trouble getting signal with a local sim card, at the time I thought it was some setting I didn't know about or that it was the network that was messed up. Then when I got home I continued to have with my at&t network, always showing no signal and no data, when I did have signal it would cut out in a few min and when I got Data it was only 2g.
So what I did was install a stock rooted rom that I had been using before, this rom took care of a lot of the errors but wifi doesn't work on it, so I had to install a kernel which was verson 3.4.0-g2d4cae8 ktoonsez, this took care of the wifi problem.
Then I looked around a lot for reasons that my network wasn't working. One potential problem was APN, I checked that and mine was correct. There was also a problem listed with IMEI and that was fine on my phone too. Then I finally found that sometimes you can reinstal NV items and that can fix your network issues. So I found a site that had NV items to fix LTE and flashed that on my phone through odin. That actually took care of my network issue! I can get network now and get LTE, luckily saving my phone from being completely useless.
Now I have a completely diff issue and I don't know if I'm missing something similar to that to fix it.
What happens is that I constantly only have 1 signal bar, then when I start making a call or send a text I all of a sudden have 4 or 5 bars. So I have signal, but somehow its not registering properly. I would be okay with this considering my phone is at least letting me make calls even though it takes a bit longer to connect, but the problem is that it's been heating up a lot and the battery has been dying 3 times a day when it used to last an entire day. Looking up this problem I found that this problem is common when you have no signal. Also when I think when I am closer to a tower then my phone has 3 bars most of the time and the battery lasts longer, aka when I was in downtown Houston I only had to charge my phone once during the day as opposed to 2 times.
Anyone have any Idea how I might be able to fix this problem. My mom had her phone unlocked the same way but she is still on official stock rom with root, and is having the same problem, so I'm pretty sure it was the unlocking process and something similar to the NV items. Maybe I needed to install a whole NV items file instead of just the LTE segment? Sorry this was so long, and maybe rambling. Let me know if you guys need any more information.

Signal Issues

Hi all
So I know that many people have reported the same issue but no one ever seems to come to a conclusion on what is causing the problem...Some say it's the network, some say it's the software etc. Anyway I'm hoping to get to the bottom of this, my issue is as follows:
I see signal issues multiple times a day where I have signal bars and phone calls and texts work but data does not. The only thing which resolves the issue is a full reboot.
I currently run Cloudy G3 2.2 in my imported 32GB G3, I saw the same issues on the stock ROM too though. The signal issues only seem to occur when the signal drops to a low "H" signal...all the time i am in the office I have a full "H" signal and do not see the issue...the issue only occurs when the signal drops quite low...even when it goes back to full again the issue remains until I do a full reboot.
Anyone got any idea what this is all about? I don't want to have to switch phones to get rid of this issue....
Thanks

Just to be sure, did you flash the lollipop baseband when you installed cloudy

Ermmm I thought it came with the baseband?

Just checked and i do indeed have the Lolipop baseband...any other ideas? From searching around it seems a lot of people have this issue!

Id say if it happens on Stock Rom as well its probably a network issue related to the cell towers in your area. So i wouldnt worry too much about it

Can't be that either as it happens in multiple locations which are all around an hour from each other I'm gonna have to sell the phone at this rate and get a one plus one or something

I have the latest 20p version already though, there are no newer versions

Have a case open with Vodafone (they have simply suggested sending the phone in for repair, not an option for me) and have a case with LG too who have only suggested basic things so far (none of which have worked) aiming to get both of them to progress the cases to their engineering teams
