[Q] 3G disconnect-reconnect - Epic 4G Q&A, Help & Troubleshooting

I have searched around, but found nothing that resembles my issue.
I keep having this weird tone occurring, usually in the middle of the night. It is the same sound that you hear when the phone is coming out of airplane mode, but it is doing it all by itself. 3G and alarm icon disappear and reappear. You think re-Odin'ing DK28 might help since it seems that it might be tied to the radio? Anyone else run into this?

I team across this as well but when I got my Epic from sprint. When dk18 came out it helped but since dk28 it stopped. Its your phone loosing a signal all together then getting it back. Most likely its the towers in your area and not something you can fix. Have you done a prl update Lately?

I have tried updating the PRL and it seems to help for a while, but it always comes back. My wife has an Evo and doesn't have this problem.
I would be willing to settle for muting the notification since it mostly happens while plugged in at night and it wakes us up, but I can't find that sound file. Any ideas where it is? I lieu of deleting it, I could just rename it and replace it with a silent file.

[Q] Help - NYC Subway issues

I know there are a bunch of NYer here so I'll throw this up (and i guess this may be a problem with anyone who uses underground transport). Does anyone else experience random reboots coming up from underground?
Is there a solution?
I have had these issues with stock and Virtuous ROMs. It normally doesn't affect my day, and in fact the only way I know it has happened is that I have to reset Swype. It doesn't occur every time either.
Anyhow, just seeing if anyone else gets to deal with this.
...
I kinda wish that every "hey, my phone reboots" thread would just get merged into one big superthread.
This is happening due to low signal. Your signal is so low (at that point) that the radio starts working harder and harder to scan/pick it up. That extra work generates heat. When the phone heats up, it reboots.
It's simple, every time I go into the subway, I put my phone in Airplane mode. When I get out, I turn off airplane mode.
That way it doesn't try to pull for a signal, when there is no way in hell it's going to get one.

Eic 4g Touch Bugs Thread

I'm seeing many users notice different little bugs with the phone (me included) and instead of having multiple threads about it, maybe we can all post it in one place where later the devs can see it and work on them once the phone is rooted etc.. Good idea/bad idea? I come from an Evo 4g with Sense rom so I wonder how many of these might not really be "bugs" but just a different user experience.
I'll start..
Accu weather app not updating location automatically
apk files downloaded from the computer and then transferred to phone are not showing up (unknown sources, usb debugging checked)
No function when touching the clock widget. It does not launch me to alarm, world clock, time etc menu. Maybe this is just a touchwiz thing as I mentioned above, I come from a sense rom.
So far those are the ones on top of my head. As I use the phone more, I'm sure I'll spot more (hope not!).
Anyone else?
Phone dialer issues
I have to reboot my phone from time to time to make a call.
It just says call ended when i try to call out.
When i reboot it works fine for a few hours.
Mentioned above plus the following so far (except reboot for calling issue):
No landscape mode using TW (auto-rotate enabled)
Red LED only available notification color (REALLY?!)
Skype video calling is upside down when using in portrait mode.
Also, phone call is automatically in Speaker mode when calling after making a Skype video call.
*Occasional phone FREEZES. As in, one minute it is okay, and the next minute, you have to do a battery pull. Happened twice since I got it on launch day.
*Browser closing for no reason. Happened 4 times since launch day.
*When plugged in with Samsung charger, phone's screen will act real glitchy
*SWYPE does not work properly, no matter the settings. Have to type normally.
That's all the software bugs I've experienced. Hardware-wise, there are reports of problems with data, 3G, 4G, and WIFI....I haven't seen any word on Bluetooth yet.

Go exchange your phone -- sounds like a lemon. No other real complaints about freezing or auto-closing apps.

Actually, other's have experienced auto-closing apps and freezing. It's in a thread around here or at sprintusers.com, I forget which.
For the first three days I couldn't get data while roaming though the proper settings were checked. Sprint customer care reset my phone and after an hour of waiting it works.
All else its great (except for the above oddities with Touch Wiz) though I haven't checked GPS after encrypting the device.

Can you elaborate on this issue?
Also, anyone else having similar issues, please chime in.
Are you seeing a circle with a slash through it (no service) when this happens?
Can you receive calls when this happens?
Do you lose 4G or WiFi? Or is it just Voice/3G?
Does it seem to happen sometime after making a call/text (~30min), or any other pattern you've noticed?
Are you rooted?
If yes, what kernel (zedomax or tanimn/shabbypenguin - trying to narrow down an issue with one of the current root kernels)?
Exchange Appt. Notification Bug
I have had multiple reminders pop up for from my Exchange calendar and i can't seem to dismiss or snooze them from the notification bar. The snooze and dismiss buttons are available but are non responsive. The only way I can get rid of the notification is with the "Clear" button which is for all notifications. Has anyone else noticed this?

I know this may sound silly, and you may have already checked this, but check your language settings. I've read about some owners that were having problems with Swype discovered that their language was set to Spanish.
Also, on the LED notifications only being Red, I've been playing with an App called Light Flow. I've at least been able to change the notification colors to Blue using this App. Also, the App lets you use "White" as a color, which still shows a Red light, but blinks very fast if some of you prefer a faster blinking light.
I have had the roaming data issue as well. It does eventually work for me though, but on once occasion it took 10 minutes before data turned on after the roaming started. I will try calling Sprint as well.
Wifi signal is bad.. but speedtest says otherwise. I think the issue is with the amount of bars displayed and not the actual signal. I was standing 5 fee fromt he router and still didn't have full bars.
Ive been having problems today with dropping data connection. Toggling 4G off and on seems to restore it even in no 4G areas. I guess it resets the radio or something?

Just got this phone friday. So far the only bugs I am experiencing are roaming in places my evo got coverage and the security draw pattern having a mind of its own making it very hard to unlock the screen. Also the wifi reception is noticeably weaker than my evo

Ive done that already and it didnt help. Thanks, tho.
Luckily, no freezes or crashes here (knock on wood).
what i HAVE noticed is the rotate bug, for instance
when rotating the phone for texting or browsing, you have to kind of
bring it up to your chest @ about a 90 degree angle in order for it to rotate.
calibrated it all correctly & i still have to do that.
this is my first phone from the Epic/Galaxy company so im not sure if that was a problem in the original Epic 4g (non-touch) but it sure is kind of annoying :/
hopefully the dev's can tweak the gyro or SOMETHING.
Poor Wifi/3g Signal
Noticed lower bars on both wifi and 3g...when in same spot on my Evo 4g I had more...might be just how many bars its displaying and not the actual signal...but not for sure...actually went into roaming a few times when with my Evo 4g I never did (even with roaming was set to automatic...now I have it set to sprint only)
Hello. Has anyone tried updating through Kies? I tried and it says that this version of software cannot be updated. I just got my phone today. I did have problems installing the drivers. After I let it install say one or two drivers, one would error out. Once I unplugged it a few times and then plugged it back it, all of the drivers installed.
I hope this doesn't mean that Samsung is not going to upgrade to ICS or else I am taking this back. I have a Samsung Galaxy Tab 7" and it won't allow updating with rooting. Thanks for any input and have a great day/night!

I noticed this too.
you have to check the check boxes next to the calender item. This is deceptive because the boxes have checks in them. But they should be green and not grey.
hope that helps

[Q] "Invisible" LoS

This is really weird.
I know people have been having problems with Loss of Service, but so far, I've only had it happen once or twice. What's really bothering me, is that I've noticed an invisible service dropping problem that's actually way worse.
Twice now, my phone has full signal bars, and isn't roaming, but my wife will come home and say she sent me some texts. Sure enough, no texts. So I reboot, and suddenly I get a flood of text and voicemail alerts. So, not only was I not getting texts, but all calls were going straight to voicemail, as if the phone was powered off.
Has anyone noticed this?
I'm not rooted, no alternative kernel, nothing. I'm completely stock. If this keeps up, I have no alternative but to return the phone. I have a job where I have to be available for emergency alerts, and this is definitely a major problem.
I mean... why would the phone say it has a connection if it clearly doesn't?
Yeah can confirm the same. Its like the phone has los but doesnt realize it.
Sent from my SPH-D710 using XDA App
This is definitely a problem. It's usually referred to as "Stealth LOS". (or "POOS" but I have no idea what that stands for.)
If you decide to keep the phone, a workaround is to set Tasker to automatically reboot if it senses no signal. It should work even for the stealth cases. Obviously not everyone will feel that they should have to workaround the issue though.

[Issue] Complete loss of signal when not in use for an extended period of time

I was using an iPhone 3G on the Fido network and switched to Bell on Thursday to get the Galaxy Nexus. This is my first Android phone, already own a Xoom.
Since buying the phone I have noticed a reoccurring issue with my signal. I leave my phone next to me when I go to bed and when I wake up I notice that I have zero bars and when I try to make an outgoing call the phone says I am in airplane mode (but I am not). Also none of my apps say they have data and my e-mail hasn't been updating.
I haven't figured out the best way to get a signal working again, but so far it appears to regain signal when I start using it for a few min or if I restart the phone.
While I am awake the phone sits next to me with full bars only 5 feet from where it rests overnight.
Anyone else encounter this issue? Is Android trying to save battery by weakening my signal and therefore cutting it off entirely? Possible defective device? Issue with Bell's signal although I seem to have full bars otherwise?
thx guys
I have the same issue. Flashed different radios and roms but still the same thing.
I've read similar issues with other people on Bell Canada.
Wonder if it's a problem with Bell.
Same Here
just finally noticed this here too in NYC on T-Mobile phone bought unlocked from UK. I remember having similar problem with my nexus one thou it was eventually fixed but as it was then now I can fix it with a restart.

Well with this only being released on Bell/Virgin in Canada it is hard to tell if the issue is network or device related
This is usually a SIM issue. Try someone else's to test, or just ask your Carrier for a new one.
In the meantime you can toggle Airplane Mode to bring your signal back.
Here are some example screenshots. In these cases my signal drops & returns very quickly without me doing anything.

I gotta run some more tests on my phone after an extended period of inactivity, but trying airplane mode last time freaked it out. It already thought it was in airplane mode when I tried to make a call. I had no signal, it said please turn off airplane mode, went to the setting, it was off, so I turned it on. I then tried turning it off, but while the check box responded the airplane logo would not go away in the statusbar. I had to reboot the device.
Hey Guys,
same problem here in germany. Signal drops when i leave the phone alone. But not every time. Over night the signal stays all the time.
sometimes even a reboot does not solve the problem... it drives me insane!
I'm also on Bell and on my second GNex. The first one had that issue as well, along with horizontal streaking on the screen so I returned it. I'll keep you posted if this handset also drops signal.

As a heads up to this topic, there is a similar issue with Airplane mode turning itself on. The low signal/no signal issue and airplane mode might be related. The thread is here: http://forum.xda-developers.com/showthread.php?t=1387943. There is also an "issue" opened with Google about it.
To throw in my two cents, I've also noticed this issue occuring infrequently in nyc with tmo. Usually during the day at work the signal will drop down even though the phone hasn't moved. Usually it comes back but I have had fairly longer delays going from no signal areas to signal areas, sometimes 60-120 secs before the device recognizes the signal. I'm wondering if this is a result of the device polling for signal less often to conserve battery power.
Keep the information coming! This is how we work out the real bugs!
this is driving me insane. I want to throw my GN right against the next wall. Signal drops and does not come back. I have to switch to 2G to regain my connectivity.
flight mode doesn't help, reboot doesn't help, switching all data off doesn't work.
What the f* is going on here? is it a provider based problem? or is it due to a conflict with ICS or anything? if it lasts i'll switch back to my good old desire ...
forgot to say: switched radio today, doesnt bring any improvement. Tried the xxkk6 and the newest UGKK7. Back to xxkk6 now.

UGKK7 isn't the newest. UGKL1 is.
Ive had the same exact issues as well. Have had a thread open for quite some time too.
http://forum.xda-developers.com/showthread.php?t=1365389
I tried UGKL1 last night and finally thought I had it working but still doing it.
I flashed Modaco lr6 this morning and haven't seen the issue since.
Before the flash, it would lose signal everytime it went to sleep
Is anyone here still having issues with the Galaxy going into Airplane mode after the phone is left in idle mode for hours? If my phone is left idle for a long time it goes into airphone mode and I have to restart the device to be able to make and receive calls. It's strange because I transferred my T-Mo account onto a new SIM card when I purchased my GNex.
I seriously hope this isn't a hardware related issue because I would be without a phone again...
This thread is a better resource to go to for the airplane issue:
http://forum.xda-developers.com/showthread.php?t=1387943
My issue was also connection drops. I since replaced my SIM card & Nexus. No more frequent connection issues. I can confirm that I still get the airplane issue, but because I am not losing my connection frequently, the airplane issue only happened once since mid December.

I'm seeing weirdness as well - when I come out from under the subway, I can't get back a signal. Going to have to revert to stock (uuuuugggggggggh) and see if it persists.
I have the same issue and it happens nearly every night. I wake up in the morning with no signal and once I reboot I receive all of my messages etc. I am not sure if it started happening since I rooted and flashed Revolution HD but either way it is extremely irritating.
I have had this problem since I got my phone mid December. Over the past week it has become worse. I was anxiously awaiting the 4.0.2 upgrade.
I just upgraded to 4.0.2 yesterday, but unfortunately my signal dropped a few minutes ago. Grrrrrr, I had hoped that 4.0.2 would solve the issue, but apparently it doesn't. Maybe 4.0.3 will do the trick, but I don't expect this to be released very soon as they are rolling out 4.0.2 just now.
Android version 4.0.2

Mic muting when screen goes off...

So.. i have had a weird problem for quite awhile now but have been putting up with it..
When on a voice call when the screen goes off it will mute the mic, leaving the other person asking if i am there.. i have to shake the phone or hit the power button a bunch. It also doesn't wake up instantly when that happens, almost like its in a deep sleep. I don't have any battery saver apps or anything installed....
I am using CM11 right now with FL24 modem, i have tried other modems.. same issue.. This issue also happened on other roms incluing vanir and others...
I did a search and found one other person with the same exact issue.. but no fix posted, was hoping someone might have an idea on how to figure this out.. thanks..
Experiencing Similar Problem
I've been experiencing a similar issue for a bit over a month, too. I'm not quite sure if it was when the screen went off, but certainly within 15 seconds of making or receiving a call my mic cuts off. It sometimes comes back after -- I don't know if that's because I shake the phone around or otherwise get the screen to come on, although the mic turning back on and the screen turning back on do not happen at the same time.
I'm also on CM11 with FL24 modem on a Samsung Epic 4G Touch, which makes me suspect it's the same problem. Do you have a link to the other forum post?
I suspect it's a relatively recent regression with CM, because I installed CM11 on the phone at the end of October and everything was fine. I first started experiencing the issue a few weeks thereafter. I can't recall if it happened after upgrading CM, or if It was after I installed Google Voice (since removed,) or if there was no particular prompt.
