No service!

I am new to android devices and i bought an HTC desire.
I have the device for about 2 weeks now and I am noticing more and more that it gives me no service in areas where the network should be perfect,i have to restart the device to get service again.is anyone facing a similar issue?

i got that just yesterday.. wasn't sure why.. I restarted the phone and Service came back.. just thought it was an oddity until you posted. how weird.

Happens to me when I'll be indoors (where there's 0 reception) and I go outside again, the phone doesn't always lock onto a network for whatever reason. Quick way around instead of restarting the phone is to enable Flight Mode (settings > wireless > flight mode) and disable it again to turn on the phone radio.

i noticed that also, when i use an elevator it sometimes does not get the network after i go out.this is becoming an issue for me because i have to keep checking if the phone is working or not.
thanks for the tip ,makes the process easier

You could also try rooting your phone and then flashing a different compatible radio rom version as this could improve certain conditions such as GPS strength, Reception, Battery life, Wi-Fi, etc.

I have a stock Desire locked in Vodafone, just did the last Firmware over the air Update and the radio updated from the worst version 5.0.0.something to 6.0.0.02 (I think, not the latest, the one before that).
Reception improoved, not by much, but to some extent. But now it prefferes to jump faster to GPRS data than before. So when I move around the house some people might get a busy tone because weather or mail is updating, and THIS IS FRUSTRATING ...
I tried from the *#*#info#*#* menu to limit it to GSM (PRL) but it made no difference.
Also it gets hot, 10 minutes of internet browsing through wi-fi/3g gets it up to 35 37Celsius and that is HOT ... Is this normal ?

Yeah - I noticed this over the weekend too.
Not for calls, but just for data.
I think it might be to do with Juice Defender.
I actually did a factory reset, just to get my data to work again.
Same problem occurred this morning, so I binned Juice Defender, and it worked immediately afterwards.
FWIW, mines is a TMob Desire...

Actually I did not want to root it since rumors have it that there will be an update on the 23rd of this month to Froyo

I was using a different Radio version but have not flashed back to the original stock version (04.00.05.11) already, after browsing for 10 mins or so, the battery temp rises to a max of 29.5 degrees celcius, which is more reasonable than 35-37 degrees celcius. Sticking with this version for now.

Having the same problem the data goes off all the time and i have to restart to get it back on. recently my phone has been getting hot after very little use.
I am rooted running froyo with the latest radio.

It happened to me today .I am on stock 2.2 , no root. I take the phone from pocket and try to call , its does not go . Now I look into phone and it says "No service " .What crap ? . Now restarted the phone and service is back .The Android is not stable enough still .Basic things like calling should be rock stable .

Does wifi kill battery faster?

Does using wifi drain the battery? Is it better than using the actual 3G or 4G?
Sent from my HTC Vision using XDA App

I'm sure someone has a way more technical answer but I would think not. I have no issues with drainage on wifi, as on 2g its on the network constantly and not continually searching for towers.

If you are connected to a wifi network, it saved much more battery than using 3 or 4g. However, if you leave wifi on but don't connect to a network, it will drain battery

ok cool thanks alot man. Idk when I'm home I just like using wifi better, correct me if I'm wrong but it seems faster. Thanks again

Turning on anything more than necessary will kill your battery faster. Not always by a lot but everything does and wifi wouldn't always be faster because it depends on the wifi's local area connection. Best way to save battery is to go in settings/applications/manage applications the force close anything you don't need running. Make sure you know what it is you're closing or you could run into some problems. If you end up killing a system app and it won't reopen itself, its nothing a reboot won't fix.

DO NOT DO THIS.
Android has its own automatic task management system, and its best if you just let it do what it does best: manage on its own.
Sent from my T-Mobile G2 running Cyanogenmod.

Well gee I do it all the time and it works fine. If it wasn't intended to be used I don't think it would come without root permissions and anyone who isn't an idiot will realize that force closing android system will cause problems. But if you wanna suggest a task manager that doesn't actually kill apps and adds some bloat ware, be my guest.

He's not going to recommend another task manager/killer, because Android already does it by itself. Plus, killing a task that is not finished just causes it to respawn. Task killers are unnecessary, and may actually hurt performance and battery life.

I agree that it's best to let Android clean it's own house normally, however I'm getting a little bit jarred off with certain apps starting themselves up at boot-time.
Paypal app for some reason has installed a service on my phone, despite the fact I've never even logged into it and I can't see why it would need a service running all the time.
Also since the latest Google Maps upgrade there seems to be something under my running tasks called Rate Places. I've not used the check-in service on GMaps at all, nor will I ever.
As well as this, since I've been running a modded CM ROM (SparksMod Extra Hot Sauce) then I constantly have Wi-Fi Calling running - again this is useless to me cos I'm not on TMob US.
Any suggestions for a decent app which can stop all these things running before they ever start, and keep them stopped?

Try "Autorun Manager"
I use it, but SOME apps will auto-restart. I think you need the Pay version of Autorun Manager to prevent those from re-launching.
I use the free version, and it gets rid of some of the problem.

WiFi is definitely causing massive battery drain on my G2 with CM6.1.1. I leave it on at night, and if I have 50% when I go to sleep, I'm down to 3% in the morning. Without doing anything.
I'm not quite sure why this is happening, but it is, and it sucks. I can't go back on 3G/4G right now because I'm at just about 4.8GB, and I don't want to go over my 5GB soft cap.
I wish I knew why WiFi was causing such battery drain...

Do you have anything updating automatically (Email, facebook, etc)? That would be my best guess. I leave wifi on when I'm at home and it isn't that bad at all. Also, I'm sure theres an app out there to let you see what is using the wifi for updates and such. I just don't know of one off the top of my head. I have an app like that for 3G data but it doesn't do wifi.

I just went through every one of my apps to make sure that nothing is set to sync, except Google Voice and Email. My battery is at 50% right now, so we'll see what it's at tomorrow morning.
As you can see from the screenshot, WiFi is using quite a bit of battery. I'm not sure why, but hopefully soon (after some testing) I'll have my answer.

Yup, 2 nights in a row, my battery has gone from 40% to dead, simply from sitting on my night stand. I wonder if this is why T-Mobile discontinued the G2... because they knew it would have battery issues, and they didn't want to deal with serving warranties? Hmmm...

Its a bit of a leap of logic to link your personal battery issue with T-Mob discontinuing the phone. T-Mob has a good number of Android phones coming out in the near future, with T-Mob really ramping up their support of Android devices. So its been very reasonably speculated that they are discontinuing the G2 in order to make room in their lineup (and stockrooms, etc.) for the new phones.
I get a full day of moderate usage on my Vision, and can get close to 2 days with low usage. That's very typical for a modern smartphone. I usually get in the range of 2-3% battery drain per hour when the phone is idle. And that's with WiFi always on (even when not connected to a WiFi network) and auto sync of Gmail and HTC stock and weather apps. You haven't mentioned how long "overnight" is exactly, but I'll assume 8 hours or so. So your phone draining from 40% to dead overnight seems unusual. WiFi typically uses less battery then the cell data network, when WiFi is available. I suspect there is something else going on, besides just being on WiFi. If the cell reception is dodgey in your area (or fringe 3G reception), this might run the battery down (even if you are on WiFi) as the phone is constantly searching for signal. Or your radio may be mismatched to your custom ROM. Or you may just have a bad battery. Also, was the battery drain any different when you were on the stock or other custom ROMs? I personally haven't witnessed the battery drain to be significantly different across the ROMs I've tried. But that seems to vary, as there often seem to be people complaining about this or that ROM causing more battery drain.

The reason I thought it might be a hardware defect issue is that my wife and I got G2's at the same time. I rooted mine and have been running CM6.1.1 for a few months now, and my wife has kept hers stock. However, the battery issue hit both our phones at almost the exact same time.
It sounds ridiculous, but conspiracy theories are fun to play with. The fact that I've been rooted so long, and it JUST happened weirds me out. Add my wife's phone to the equation, and it's even weirder. I kept my phone on WiFi and 2G networks only last night (yeah, about 8 hours), and the exact same thing happened.
Maybe I should just get a new battery, I don't know. But I do religiously delete apps I don't use and make sure the ones I do use are syncing as minimally as possible.

How do you prevent 4g signal from zZZ-ing?

It's becoming rather annoying that the 4G signal constantly goes to sleep once the screen is off. I was on my friend's Galaxy S 4g on T-mobile and his managed to stay on constantly (it's actually the default connection and you won't even see that 3G connects). Once the screen on Epic turns off, the 4g signal goes on sleep, making me lose any type of internet connection...
I've tried this way: http://www.groovypost.com/howto/mobile/prevent-phone-4g-wireless-connection-sleeping/ but has proven to do nothing to help with the situation. Anyone know how to prevent it from sleeping??

Unless you're tethering why wouldn't you want it to sleep?

T-mobile's 4g is 3g turned up to the max. Sprints 4g acts like wifi.

Mainly because i want to be loading my webpages at 4g all the time, turning it on and off is just annoying and slow, since battery isn't an issue for me I want to take advantage of the speed game

Uh, 4G icon's Zzzz means that it's idle. Just like when the 3G icon says D instead of showing arrows.

You aren't losing a connection. It just means you don't have any data activity. Same goes for 3G. If it *isn't* displaying the idle icon, you're transferring data. If it is, then data has been idle for a few seconds, and the radio goes to low power to avoid burning through your battery. It's not sleeping though. Also, you're probably relying too much on the icon - it's slow to refresh, and often doesn't correlate to an immediate data connection. So, just leave it be. Nothing's happening to your data connection, data's going to and from your device as it should be. (Your laptop's WiFi, and also the Epic's, do the exact same thing.)

You are loosing a connection when this happens. I've been looking for a fix for this for a long time. Unfortunately I think that the sprint side is at fault. I use my phone to hook my desktop to the internet and see this going on all the time. Perhaps some kind of app that pings the server every 3 minutes might help.
My work around for this is to set the display to not turn off when connected via usb in development settings.

Perhaps there's an issue with your ROM? I tether *constantly* when I travel, over 4G. When I'm just sitting there doing nothing, it switches to idle. I've *never* lost a transfer, a session of any kind, or anything otherwise, and I generally stay tethered for hours on end. Are you positive?

Sorry but i never lose a 4G connection if i'm transferring data EVEN when the screen is off.
For example, i use Tune In to stream BBC London 94.9 all the time and i turn off the screen, and the stream goes on just fine.

Call sprint and ask them for your MSL number. Its a 6 digit number. Go in your dialer... now

Long press on idle sleep and change the value. If im not mistaken its the unit in minutes. After your.done reboot because 4g will.become. unresponsice for some odd reason. The highest is 300.

I think the phone let's certain apps hold a connection open while in standby while others don't. For example pdanet keeps it open but downloading install files for games like dungeon defenders the phone lets the signal sleep. Anywho the above works.

I've done that already- doesn't work.
How do I know there's no connection? It's simple- open up gTalk on 3G (even when it's on D) and have someone IM you, it'll go through (almost instantly). Now repeat with 4G, turn the screen off and wait a few seconds or just know that it's on zZZ. Have someone IM you, it wouldn't go through until you establish an internet connection (hit refresh in your gmail app to revive it or go browse the internet), only then will the IM go through.
So all in all, it proves that there isn't an internet connection when it goes to zZZ

Yea 4g works like wifi hence the sleep. Somethings wrong with your phone or rom I've done the above on.both my epics on multiple roms and its always worked. Also I hope you know its going to shut off regardless. It only stays on it there's an app actually downloading something. I dont know of a way to keep 4g permanently on. This will only prevent the sleep when the screen.is shut off. Without it 4g sleeps no.matter what your doing. Sounds like your just going to have to.deal with it until someone with enough need comes up with something.
Sent from my SPH-D700 using XDA App

well I'm using the sprint stock rom....sigh* this sucks

I can only conclude that leaving the screen on is the only way to keep the 4G connection stable- which sucks a lot since the display sucks up more battery than the 4G radio does!
If anyone comes up with a solution or anything (maybe flashing a different rom would help- if it does, please recommend some) please let me know! Thanks a bundle!

I am having the same problem as in the OP, except on my EF02 deodexed ROM when it comes out of sleep it doesn't re-establish the connection.. Anyone have any suggestions?
[email protected]
Edit: I forgot to mention that I have reflashed through odin, and cwm to no avail. I also have tried EC05, EE02, EF02, and EF10 modems. It seems to be doing it on all of them.

I'm fairly certain it stays connected, it's just not active.
The TuneIn example is great, that's an app I use frequently. I also use Pandora and Slacker and they also continue to transmit data even with the screen turned off. If I get an email I get notified, if I get a facebook message I receive notification, if I receive a video call request it notifies me.
It has been the same for me both on the stock Epic and now on SRF 1.2, there is no reason you should be losing the connection if it is stable prior to the screen shutting off, IMO.
Maybe there is something more going on here. The only times I have ever had problems with my 4G connection is when I had certain apps installed, they tended to disrupt the data. Try uninstalling a few data intensive apps and see what happens.

Thanks for the suggestions. I actually created a new thread because I believe my issue is different than this OP. It's under EF02 4g issues or something. (can't remember right now) But it is specifically when the screen turn off. I just went in and kept the screen on while plugged in and it was fine. For some reason after the screen turns off and I turn it on a minute or so later, than even though 4g shows active it won't transfer data. The only apps I have that might be data intensive is email, or possibly SNS pulling FB data.

I've had issues with this also, as I stream movies off the net on my Galaxy Tab 10.1 while tethered wirelessly to my Epic. Once the screen is off and you leave it be data will go through for about 2-3 minutes then stop until I wake the phone up and turn on the display. It's annoying while watching movies and every 2 minutes it stops because the data connection on the phone stops.

Force/increase 4G connectivity vs 3G, auto tethering when connected to power

I've got a two part question for some issues I'd like to address while on 4G (some I've called Sprint about, others I know you guys will have the answer since I'm rooted) that I hope to resolve.
My issues with Sprint is that if I'm on 3G and looking at images via websites, pics obviously load slower, but they're always nice and crisp. I notice that when I happen to be on 4G and go look at images, suddenly they load super grainy. I spoke to someone else who is also on Sprint w/ an LTE 4G phone (not a Note II, something else) who experiences the exact same problem. I've called Sprint about it, but I get the usual run around saying they're addressing the issues, fixing towers, etc. When I first started getting 4G in my area about 3 months ago, it was BLAZING fast, connected the second I came off the freeway and stayed on strong. I realize over time that I'm sharing the same signal with others, but damn.
My issues that I'm hoping you guys can assist with is in regards to the phone staying connected to to 4G more via changing thresholds. As I id before, it was awesome. Now it's gotten to the point where I or the phone have to be near a window, or occasionally I can leave it on the top edge of my couch...but if I happen to handle the phone to answer a text messages, it'll often drop back into 3G. The problem is that I use my phone tethered to my laptop for watching TV....Top Gear, Family Guy, etc that I stream. On 4G it's great, but once it drops to 3G it turns into a buffering nightmare and some shows/sites can't handle jumping around for time frames, so lets say if I'm 15 min into a show, go into 3G and come back into 4G, the show never recovers and I've got no choice but to restart the show. I'm just curious if there's a way to change at what point/signal strength that the phone wants to swap back and forth and basically ask it to stay on 4G more often than not when I'm at home where I actually get 4G.
As for tethering, I'm a stock rooted ROM using TrevEMod tethering because the stock tethering app won't stay turned on, I'm assuming due to using the stock ROM. What I'm curious about is a way to have the phone automated in that once I plug it on, the tethering app turns itself on and then back off again once unplugged from a power cord. At one point I'd used some app where it had me enter parameters to do this, but it only worked to turn on the stock tethering app which won't work.
Bottom line is I'd like my phone to stay connected to 4G more often than not, turn on tethering when plugged in and turn it off when not.

as for the tethering, if you are running the stock deodexed rom, there is a mod you can flash to make the native hotspot work then you will be able to use Tasker or however you automate it turning on. if you are running stock odexed you could always flash stock deodexed, if you were intent enough on making it work.
here is the hotspot mod: http://forum.xda-developers.com/showthread.php?t=2232553

I truly don't know if the stock ROM is odexed or deodexed, I just did a simple rooting procedure and nothing more so I could install a tethering app. Maybe I'm just being naive, but coming from my Epic days where I rooted, ROM'd, kernal'd, OC'd, etc days where I removed tons of apps, added others, etc I never was able to get battery stats/calibration to work correctly, which in turn wrecked havoc on that phone...phone would get super laggy, bog and stumble, then I'd reset the phone and I'd go from 20% battery life to 3%, then realize why the phone was freaking out. Now that I've got this Note II, it works great, I've never felt the need to OC or anything (I wouldn't mind removing stock apps but the SDX Stock App Removal Tool doesn't work), so I'm kinda hesitant in flashing any sort of ROM for fear of reliving past experiences...right now the phone simply works great, I'd just like a few simple features. Any input to sway my decision?

i hear ya, i too like a nice stable setup with everything working. your system is probably odexed if al you did was root, but if you have a file explorer app, when you go into /system/app, you will see each .apk also has an associated .odex file. the deodexed rom has the odex part added back into the apk, but otherwise is exactly the same, no tweaks or anything, every bit as stable, and with nothing removed, but it is easier to make mods for a deodexed rom, such as the hotspot mod!
the decision is yours. it is always a bit of work to flash a rom, but this is defintiely a way to keep the stabilty and reliability, and have the hotspot working the way you want it to! the rom is here: http://forum.xda-developers.com/showthread.php?t=2241930, if you choose to go this route. this is exactly my setup, with the hotspot mod, and it runs great.

I'll read the thread, thanks for the link. Any suggestions for something that will enable the tethering app automatically based on being plugged in, and I've had no luck finding anything in regards to people changing thresholds for the 4G connectivity.

no problem. the app Tasker from the market does things like that, i think it costs a few bucks but it's well worth it. and perhaps there are others.
for the 4G thing, i don't see any setting for that. there are other people who know a lot more about network stuff than i do. there might be a dialer code menu where you can set to receive LTE only, but sorry i can't be of more help there. good luck and have fun!

Removing cellular from phone?

Hello all, I have been using the d2spr for quite some time... without mobile. I have no service on the phone and have no problems using it as an esspresso device like my p5113 tab 2. On my tab two there was a thread about removing the cell from the device, which I will more than likely have to look up again for that device. Is this possible for this phone? Anyone have any experience removing cell from the phone. I have read that searching for signal reduces the battery life, and I have yet to try it on the phone. If anyone can give me any pointers on this would be great. Also if you know which files to delete would save me a crap load of time searching for it.... thanks in advance...

are you basically trying to use it as a galaxy player? (i.e. an android version of an ipod touch?) if so, ive just put mine into airplane mode and turned wifi on manually. It greatly improves battery life as its not using the cell radio.

not exactly I use it as a voip phone and remote control as well as play various games, though there is no service on it, it shows the mobile connection. With the tablet it was a wifi only tab so removing cellular feature from android really increased battery life. Though I was not sure if it would work the same on the d2spr... not quite sure where to start though so thought I would ask, but thanks for the alternative, I am not sure about using airplane and wifi together as I have not tried that before.

gotcha. well, if youre using strictly voip, then the airplane mode and then turning wifi back on separately will work very well. like i said, ive done that with other devices and it substantially increases the battery life. Give it a whirl, what can it hurt?

Just an update with the steps on what I did.. as well as the results. With rooted device I deleted the 3 folders telecom, telephone, and another that starts with a tele that I can not think of. They are located in system/priv-app folder on root of system. (Using root explorer) After that I reboot, and all is working fine with no cellular at all. I have been letting it sit just to see how long the battery lasts on standby. So far I am at 28 and a half hours... I still get notifications and wifi works smooth. In the battery section in settings it currently reads charge remaining 8 days. Anyone with no service like me might want to give it a try... if something does not work all you have to do is re-flash what ever rom you had and that will put the folders back. and install cellular on the phone again... I would say that is the number one battery drain of the phone next to the display...

Day seven of my battery test and So far it appears that without cellular on the d2 you can get up to 10 days of standby charge. I did not use the phone at all for anything but to check status. Also, If you notice the small change in the curve, it is because it downloaded updates. It was connected to the internet the entire time...
