I have Epic 4g on SPRINT USA. Not rooter, latest original firmware. I recently notice that if I get to no signal zone like subway, radio icon is crossed circle; I guess phone suspend radio and randomly check to preserve battery. Problem is that once I back to area with full signal it may take 5-10 minutes for phone to get radio back. If I attempt to make call it will say phone not registered on network. It will take me switch airplane mode on off to enforce registration on network sooner. As the result if I am located in no signal zone for an hour and have signal for 10 min and back to no signal it will not get my sms, voicemail and email during that time. Is that waiting time adjustable? Any idea?
When I'm heading down into the subway, I put my phone on airplane mode because its pointless to have the radio on when there's no signal and it wastes more battery, then when I get out I wait a few seconds and then turn airplane mode off and it reconnects like nothing.
Just try turning I on when you're going in, and when you're outside again just turn airplane mode off

You could use Tasker for something like this easily. Its what its made for.
No Radio / long time to register on network
But I do not want all time to manage my phone when I go to underground area or at no service area. I can use tasker, but should not it be handled by sprint? Also in tasker you expect me to use cell near and check it repeatedly once per 3min? Not much sense, as tasker will not see event when display off, it by default use to check once per 10 min, which is not good in this situation.
Any other solution? I do not expect all people using subway to turn on airline mode

Is anyone else here having similar problems with the radio on their HD2? Mine seems to crap out severely when it comes to 3G. I have notice dhtat just about every time the phone is powered on, it will turn the data connection in the settings off by default regardless of It's state when the phone was previously powered on.
Also, I have noticed sometimes the phone will sporadically switch out of 3G mode and into phone only mode and I must go into the settings menu and re-enable it.
Also, Sometimes (The phone has done this twice today so far), the phone will still indicate that it is in 3G mode but when I attempt to browse the web it will return a page cannot be found error and the only way to fix this is to go into settings, disable and then re-enable the data connection.
My current radio version is 2.08.50.08_2. Is there something better out there?
I had the same problem with the data connection shutting off. I downloaded HD2Tweak and it helped keep it on.

It's been a while, but I think I got it here. It was the English version.
http://www.montecristoff.com/hd2tweak.htm
Under "4. Data", I turned on Internet, MMS and Data to be on permanently. Worked like a charm. First day, I had 13 hours straight of data connection. Before using HD2Tweaks, I never had more than 20-30 minutes.
I've noticed today the 3G connection went from full bars to none and also no phone bars.. and it reconnected again.
Sometimes it will not reconnect to signal for a while after I leave underground train station.
In areas of weak-medium signal strength, I've noticed it switch between E and 3G a lot and drain battery much faster.
The signal reception is generally excellent in the city, except if inside a building with thick walls, so I don't understand why it has signal issues when outside.
My phone has recently been messing up, and it's rather annoying.
I'll unlock my phone, try to use my data connection, and it won't load a page. I look at the top, and there is no 3g icon. Only way to fix it is to put it into airplane mode and back again. Anyone else have this issue?
I have a replacement on it's way because it keeps shorting out with a line in jack, but it wont be here for a while because of the back orders.
I searched the forums, didn't see this topic addressed, sorry if this is already being discussed.
I have the same problem with 3G dropping into 1X with a decent signal. I got the Real Signal app from the Market which will display the EVDO and CDMA signal separately and discovered that the EVDO signal was at least -10 to -25 db weaker than the CDMA signal. I reported this to VZ and they were supposed to send some one out to this location to check the tower signal and get back to me but have heard nothing for about 5 days now. Will check with them again tomorrow. I think that it is an antenna problem or radio front end problem on the 1900 MHZ band. Need to find out something by the middle of next week because my 30 day period will be up then.
It doesn't just lose 3g, it has no data connection at all. Only way to fix it is airplane mode or power off then on.
Mine is liking to drop my signal to 1x. And my call quality sucks.
Mine stopped loading web pages all together. You have to clear the cash is is defaulted to 6mb. That is what Verizon told me to do and the phone works great. I run the world at war page from face book all day. Face book is blocked by my company's software. Every night I clear the cash.
Anyone else having this problem? I don't remember having this happen on my MT3G.
It's really eating up the battery.
I am on JI2, and I never experienced this until last night after using Odin.
you have to change the wifi sleep policy in the wifi settings. Got to settings, wireless networks, wifi, then press the menu button and select advanced.
OMG! thanks, you're a real life saver.
Sorry to bring up an old thread. I have it set to never sleep but it still does. Any ideas? Seems when the display times out, it switches off wifi.
I have wifi on all the time at home and it's set to never sleep. Sometimes I see both the wifi and 3G icons. I know my wifi signal is strong, so no idea why the phone sometimes also seems to need a 3G data connection. One example is when I test GPS at home the 3G icon will pop up briefly. Another is following a reboot. But I see other times as well, and sometimes it stays for quite a while, but eventually goes away. I wonder if perhaps some ports get blocked by my router and the phone uses 3G communication to get around it. Bit of a mystery, but I don't see any other negative symptoms.
Here is something I have experienced. This is regardless of what ROM I am on.. Stock, Bionix, whatever...
I have wifi turned on at work. Sometimes I would see wifi and 3g on at the same time.
Now today, while texting, I noticed that my Wifi connection dropped to nothing, and at that point my 3g kicked in, which I expect it to. But when my Wifi reception kicks back up again, my 3g didnt turn off. I turned off Wifi and turned it on again, and my 3g turned off.
Anyone else getting the same experience?
samnada/ELStiko, That's what I'm really seeing too as I thought my wifi was just going to sleep.

I'm pretty sure my wifi isn't going to sleep. The wifi icon is on all the time with at least 3 bars. My cell signal is definitely weaker in my location. So, if it's seeking the strongest signal my wifi will always win.
Besides the possibility that my router is blocking some ports the phone wants to use, there's also a possible security issue. I know at one point the TMO My Account app would force a switch to cell communication versus wifi and I believe it was due to security concerns. Maybe some apps do the same thing.
I just did a GPS test, got a lock, stopped the test, closed the app, and the 3G icon stayed up for a couple of minutes then went away. Just one example.
Does seem odd, but I've just assumed there's some rational explanation. Could also be a bug...
your lucky you wake up and you have 3g. i wake up my phone is always on edge. lol

Hi.
I work in a TEMPEST protected area most of the time, and other times underground. At these places there are no wifi, no 3G, no GPS signals etc. Like skip zones on steroids.
Is is possible somehow, perhaps with Tasker, to make the phone disable all these functions and then only search for one of them (probably 3G, any provider) occasionally and when signal is found search for the others aswell?
My battery drains alot faster when I'm at these places compared to when I'm at home.
From what i understand of Tempest, is that you probably should have left you phone at the reception desk before entering the room.
well, you can switch to and from airplane mode when entering and leaving the tempest area.
or you can select, 'use 2g networks' - saves battery, and also select 'search automatically' for networks (under settings somewhere) depending upon which ROM you have installed.
as for apps and such, i dont know any, Luckily i dont have this issue lol
OR.... you could look for another job somewhere in open view of many many telephone pilons
Airplane mode! This will stop drainage with if there is no reception. With no signal ur phone is constantly trying to find signal it require lots of energy.

You're very correct. But I didn't make the rules. There are such areas aswell, thou.
About airplane mode, yes that's a solution. But I would like some automation. So I don't have to remeber to turn the thing on again after work.
You could use some app that turns on/off airplane mode at specific preprogrammed times, for example "Setting Profiles".

yupss this is what causing your battery drainage as your phone keep searching for the signal. I once worked in a rural area where the signal is a ***** and the battery doesnt last even for a day. Either you turn off your phone or keep it in flight mode!!!!
ok i have recieved my second, sgh-i337 build number kot49h.i337UCUFNC1 Kernel is Now 3.4.0-1125940, from assurion with the same issue. it seems that after the latest OTA update my mobile network fails randomly throughout the day. I cannot use web, if i try to make a call it gets stuck "dialing" and cant even end the call. I try to turn on airplane mode and airplane mode gets stuck between on and off. PS half the time this happens i show full bars but no 4g or E or any network designation the other half i show no service. i know its not where i am by the way, this is testing it in the known full bar location of my house, and downtown at my work, where i also have full bars.
So people sound off if this update screwed over your phone too. also any suggestions are welcome.
