Phone loses reception, restart to get it back?

Love love love my Desire. Few little problems here and there (Music Genre, Battery life etc) but the one main thing that is really bugging me is, that if I lose reception (I live in a area with lots of valleys), it will never regain reception even if I enter a town centre or City. I always have to either switch Airplane mode on then off. Or more often than not, turn the phone off completely and switch it back on, where it then finds reception straight away.
Anyone else getting this?
I'm on Vodafone and using the latest Generic Rom

I'm not sure if this is the same problem, sometimes i
have no data connection (i guess 3x since i have the phone).
I see some bars but no Edge or H (3g) sign and obviously i have not data connection ... dunno if the phone part work, will try next time.
anyway, i could get the data connection back by switching from 3g to GPRS mode and later back. You can see in the bar that for a very short time all GSM connection is gone ... i guess it's similar to switching to airplane mode ...
Maybe it's worth a try for you, maybe it's totally useless
btw: i'm living in a city, the nearest celltower is just a few meters away.

I have similar issues but I had the same issues with my ADP, not just the Desire.
Inside my University buildings I lose reception very often and the GSM connection always reestablishes itself but not the Data connection. When I reboot my phone the same thing happens. There is a good chance that the Data connection wont initialize and I have to switch to Airplane mode and back to get the Data connection. Really frustrating sometimes :/
Another very, very annoying problem I have is that sometimes it shows a data connection but it can't be used. It shows E/3G/H but whenever I start an app which uses data, it always times out.
Another problem, which is probably not fixable, is that my Phone likes to jump between E/3G/H quite a lot and every time it does do so, it seems like the app using the data connection has to reestablish the connection. This led to quite some timeouts when it was constantly jumping around.

I get poor 3G reception on my desire ( orange UK ) , have to go outside in the rain to get a better reception

vodafone have been getting worse and worse of late, I travel from surrey to london (central) every morning and was getting the same thing. I was even getting this all the time with a blackberry 9700, It is not the phone as I tried tmobile sim card in the same areas and didn't have the problem. Only 8 months to go of my contract which I will not be renewing.

I have an issue where if I use wifI at home for an evening, when I switch wifi off, the 3g data connection does not re connect. If I re boot, it connects immediately.

Assuming Vodafone uses Sim cards. I just had the same issue, here in the states with AT&T. I thought my Tilt was at fault so I borrowed a little Samsung flip phone and put my Sim in it but it did the same thing.
I had AT&T replace my Sim card and so far, 48+ hours, it hasn't happened again on my Tilt.
Might be worth a try.

Thanks, might try changing the Radio version and see if that helps first, if not will give Vodafone a call.

I have this same problem at home (in South London) with my desire and had it with my G1 too (both on T-Mobile). I'm pretty sure it's a network issue rather than android or the phone. I constantly have 3 bars of H signal and during the daytime it's blazing fast but after around 5pm and all day at the weekends it becomes basically unusable with network timeouts more often than usable connections. I work 40 miles away down south and I get a consistently fast data connection down there with none of the time out problems.
I also tried using a t-mobile sim in a 3g dongle and had the same issues, it was great during the day and incredibly slow with loads of timeouts in the eve. It reminds me of when unmetered ISPs first came out and couldn't cope with the amount of bandwidth being used, I'm pretty sure this is a similar capacity problem in some areas.
I've been in touch with t-mobile and they are escalating it to 3rd line support so will wait and see what happens. As it's at home I can use wifi and it's not the end of the world but it some respects I wish I hadn't upgraded and switched networks instead, my gf's on O2 with the phone that is not to be named and doesn't have this problem at all.

In response to your most recent query on a different thread you had posted (now closed):
Will changing the radio help me?
Currently got this issue happening daily
http://forum.xda-developers.com/showthread.php?t=676866
If I lose reception at any point, I have to either turn Airplane Mode on and off or restart the phone to get ANY sort of reception.
Currently on 1.15.405.4 Generic Rom with Baseband version 32.30.00.28U_4.05.00.11

Yes, by updating the Radio version this can improve things like battery life, network reception, Wi-Fi, and GPS signal strength, but this also depends on your region - it will either work better for you or could be worse. It may be worthwhile changing to Radio 4.06.00.02 for a few days and try to establish whether or not it improves your situation. If it doesn't, then just revert back to the stock Radio version.

I had a very similar problem on my Touch Diamond 2. It turned out to be a faulty aerial and had to go back to HTC for repair. Worked ok for a while after that, then it started again. An update to their latest ROM then solved it. So a hardware issue and a seperate software issue both produced the same fault for me.

[Q] 3g everythere but at home????

I have a problem with my Tmobile g2 running 2.2, it is all stock no modifications whatsoever other than handcent and fancy widget.
The problem is I can not connect to 3g or hsdpa network when I am at home. By this I mean the cell tower that provides service when I am at home. I have txt and calling capabilites but I have no data whatsoever. I have to manually switch to 2g or edge to check email or use the browser. I have called tmobile and they keep telling me that the problem is with my phone, however when I am 2 or 3 miles from my house and it goes to any other tower on the planet everything works fine.
I have searched the g2 forum here but could find no answers. I apologize in advance if this has been indeed covered or discussed to death and I have just failed to find it.
I did find the *#*#4636#*#* option and when it is on 2g I can run a ping test and it finds the server just fine, but on 3g it always fails to connect. Again this only occurs of course when I am sitting at home!
Thanks to anyone who can shed some light on this or point me in the right direction because leaving it up to tmobile has proven to be fruitless.

It might also be worth mentioning that i replaced the sim card today as well, this too had no effect on this phenomenon.....

My mom's nexus s has the same problem. Only difference is that when i walk out the door i get 3g. Once i walk back in, I get edge...... I think its might be just tmobile frequencies poor ability to pentrate walls.

Sounds like a problem with the 3G network in your area, or just a weak signal there.

I know its not the signal strength, I always have full bars at home Its something to do with the network....

Full bars on 3G or 2G ? If you have full bars on 3G then it sounds like a network problem.

I have the exact same problem, but my building is probably over 100 years old with 300 coats of lead paint on it. It depends on your building. Signals can bounce off of mirrors for example and other materials. The more material the signal has to go through, the more attenuation happens.

I have a similar problem, my G2 can't maintain a consistent connection, I will go from 4 bars of HSPA+ to 4 bars of Edge to nothing (lost connection to network) and it will jump around wildly between these three states (every few minutes). My wife's MyTouch 4G doesn't do this, my G1 did not do this, our kids (dumb) phones have consistent connections.
I know it's some interaction between my phone and the TMO network, I'd say it was a defective phone except the only place it happens is inside my house.
I wish that TMO offered a microcell.

There is no reception problem, I have had the phone working here for awhile and it always has full bars, like I said I can hop in the car and drive a couple miles and it works just fine. Tmobile finally got back to me today and said they are having their Engineers troubleshoot the tower that provides service when I am home. I hope they get this fixed soon, they said 72 hours.......

It's that anti-cellphonereception chemical they put into paint!!

CDMA GNex Signal Issues

I just got my VZW Galaxy Nexus this last week and I've been experiencing signal issues. Often when check my phone, it will have no signal at all which can take some time to come on, and then its sometimes even longer before I get a data connection of any kind. I am in Lincoln, NE so I have 4G here which works great when it works. Is this a common problem with these phones? I rooted and installed CM9 that day I got it so I want to determine if I have bad hardware that needs to be exchanged or bad software that can be fixed. I found the 4.03 leaked radio on the boards here and flashed it, which has seemed to help some but I still have issues. What is everyone's experience with VZW and the GNex?

Common problem seems to be the complaint of a longer "connect to network" time, both on startup of the phone and if data is lost or switched down from 4G to 3G
The consensus seems to be that its a s/w issue that can be corrected.
Oddly enough, I was standing in the middle of our local shopping mall with no bars, yet did a Google search for "Verizon Wireless" (go figure, right?) and it came right up....no it wasnt cached. Just shows that our bar readings may be inaccurate, so who knows what else might be inaccurate. I also had my phone right next to a demo GNex at the Verizon store, and the demo was showing 2 or 3 bars of 3G, while mine had 1 bar of 4G......so which is better, 1 bar of 4G or 3 bars of 3G? Judging from app download speeds, Id rather have 1 bar of 4G anyday.

I have seen some comments about the bars in the status being in accurate, however when mine has no bars it seems to be that way. I am unable to use the internet, text or call which is an issue for me.
I also should note that I use JuiceDefender to control my data connection. While this should have no bearing on my phone/text connection, I am wondering if it may have some affect on the 4G connection even after I have the screen on for a bit.

I have 4g disabled and haven't had any issues. I'd try disabling it, restart and see if it happens again. Make sure its still disabled after restart.

I've been having big time issues with mine. Lots of time I go to pick up my phone and it has service, decent service, but won't connect to data. Once I'm connected it is not an issue but if I'm on wifi at home, and turn it off, it just doesn't want to connect unless I reboot.
Rooted and tried a new radio. A little better but still has been doing some weird things.

How long have you had yours? My biggest question that I'm trying to answer right now is if I have subpar hardware. Since the phone is only a week old I know I could return it to stock and easily get VZW to give me a new one. This may not be the case two months from now however.

I've had it since it's been released. The newer leaked radio is better, but it also does weird things too. I don't know if this is because I'm in a 4G town or what.
I don't get 4G where I live, but my buddies with a Bionic and Rezound do here at my house, albeit it's very sketchy for them.
Thing is, I'll have good 3G signal if I'm driving, but for some reason (at least with the original radio) it wouldn't connect. Still testing.
So far the newer radio has been better, but hasn't fixed my issue.

at my house it sucks a few blocks down or anywhere else its rock solid so i just wifi at home better for battery anyway

I hit dead zones where i really shouldnt be. Downgraded from 4.03 to 4.02 and the jury is still out. Might be overall software issue like OP said.

Sorry to hear you're having the same problem, but I am glad to hear this sounds like a correctable software issue and not isolated bad hardware. Hopefully VZW will make some improvements to their LTE network and get some radio updates for us soon. I'm in the same boat as you, the 4.03 leaked update was a definite improvement, but a far cry from being a total fix.
As for when my data connection is working...holy hell is LTE fast. I'm clocking it in at 12-16Mb/s, which is killing even my home cable connection. I was confused as to why something seemed slower when I was at home using wifi. I disabled my wifi altogether since I'm lucky enough to have an unlimited data plan still.

Big issue
I have replaced three verizon Galaxy nexus's....all of which, each day i switched...i was either on the phone with a tech dude or (2 of them) one on one at the verizon corporate store.
All of them confirmed that there is a reception issue.
I reside on long island...specifically in the nassau area...4 towers around me..its HEAVILY 4g and 3g...3g is lower than 1mb...i actually never reached 1mb.
ever rep said its 'odd' and 'seems wrong'
now i love this phone...the one i have now..no different then the others..and unfortunately im waiting for the one i mailed to reach them ..to switch yet again.
the problem is..idk if i can handle this issue (4g drops to 3g and has to manually move back which takes forever..and very very slow pick up on any of them)
i want to believe this can be solved by a radio update..but judging by the insane amount of tries i have (every type on every version 4.0.1, 4.0.2 and 4.0.3 with kk6..there is no improvement,
im praying its a software..im waiting..and i have a feeling come january 15th...when everyone who has the phone is officially locked in it and loses the worry free exchange..is when verizon or samsung will actually admit whatever problem this is.
what kills me is i left tmobile for this (7+years) all nexus's ,,all unreal connections with free tethering and $65 a month (tax included)...my wife took my plan...and i took hers (she is grandfathered into unlimited data)
Now she has a sgs2...clocking in at 12mbs at home..ON AVERAGE...with fasstt radio switching...mine is unbelievably unstable sometimes can hit that but averages at 6-8. and in this house my wife got amazing connections on her previous 4g phone. very odd stuff, hers to the 4th one being the lucky one!
go figure!

I really wish this phone was more reliable with its signal, and hopefully VZW will get it taken care of. I'm debating about calling in to talk to a tech, but I'm not sure if I even want to because I don't expect anything to be done, and I don't want to swap phones for another one with the same issue. At the same time, I think I'd rather have this phone with some issues over the Rezound or Razr (once you go ICS, you can never go back)

Virtually no service after root

I got my phone the day after launch (delay on pre-orders) and enjoy it so far. I'm coming from an HTC Evo 4g, which I loved, but it's 2 years old, so it was time to move on. The first few days, the GS3 was great. Good service, even in hard to find service areas. I recently rooted it with CWM and the super user thing. I wanted wifi tether while at work, like I did with my Evo for the last year. After root, everything seemed fine at my house. I noticed when I got to work though, there was no service. Not uncommon for my building, but usually it's spotty throughout. I then noticed the time and date were 3 days off on my phones display. I found it odd that it hadn't updated this all day at work. I drove home thinking the root messed something up, as I'd seen other posts about no service after rooting the phone. When I got to my home town, my service came back. I thought I was in the clear. Today on the way to work, same spot, I lose service, and it didn't come back until I made it back to my home town at the end of the day. I understand service may not be great in some areas, even though I had fine service with my evo, but to lose service in all but like 3 towns, virtually makes my cell phone useless to me. What is going on? Was it a bad root? Can I undo this? I didn't backup my rom, because I actually rooted it during a recovery process with a bad firmware upload. I can understand if I lost service all together, that it may have been a bad root, but this seems to be a different case.
How can I remedy this?
Thanks!

Simply rooting shouldn't have any effect on your signal. I have the Sprint version, and rooted less than 48 hours after I got it. I didn't notice a change in signal strength at all. It's still been about as good (maybe slightly better, especially for actual data performance) as my SGS II on Sprint.
Sprint is doing a lot of network upgrades at the moment, so that could possibly be the cause. What city are you in?

Rooting should have no adverse effects on signal.

I live in Salem (about 20 minutes north of Boston), and drive through Beverly on the way to work. By the time I leave Beverly into Hamilton, signal is gone. All through Topsfield, and Ipswich. My girlfriend, and other people I know on the sprint network, do not have this issue. I thought it might be the network upgrades, but wouldn't it affect all sprint users? Even my father, in the same area, on the same plan, has signal.

Sorry for the double post. Is there any apps or settings I can use to enhance the tx/rx power of the phone? Or maybe change the frequentcy the phone updates the signal status?

What's wrong with my Note 2?

Dear T-Mobile Note 2 Fans,
I absolutely love my Tmo Note 2.
However, I have one issue that's bringing me great distress and that I hope the community can point me toward a resolution.
I get no to very weak intermittent signal (no bar) at my home. Other places, I get normal signal.
Phone:
My phone has the latest stock T889UVBMD1. It's rooted. Immaculate. Never been dropped.​
T-Mobile Coverage:
There's excellent T-Mobile coverage at my home area 2G/3G/4G/LTE.​
Experiments:
I have taken my sim out, and inserted it into my wife's T-Mobile HTC One, and have gotten full bar 4G/LTE strong signal. Hence, This exclude possibility of bad sim or poor T-Mobile coverage in the area.​
I have installed other modems (BMB4, VALL4) to no avail.​
I have installed other roms (Jedi Master 16 to no avail.​
I have used KIES to completely restore my phone back to factory state to no avail.​
I have tried going into Setting ---> Network Mode and changed the settings to no avail​
I have tried going into Service Mode via *#2263# and tried to force it to LTE/WDMA and WDMA ALL mode but to no avail.​
I have used Open Signal app on both my wife's HTC One and my Note 2. It seems like the HTC One is connecting to the nearest cell tower. Hence, the strong signal connection. Whereas, the Note 2 is not connecting to the nearest possible cell tower.​
Please kindly help me resolve this issue. Any other places aside from my home, my phone works perfectly fine. At home, I get no to very weak non-usable signal.
Many thanks in advance.

I had the same problem, what worked for me was going into network settings *#2263# and selecting (2) wmcda - all
I get full signal everywhere now & still connect to lte on the data side.

Thank you for the suggestion. I did try *#2263# but to no avail. Zero bar
As if there's an invisible force field around my house preventing JUST my Note 2 from the network.

Seems like the internal antenna is having an issue. Hmm, is it overheating?
Only reason I ask is I ran into this issue but with my old GS3. The antenna portion of the phone was burning up at times and not sure why exactly. So I decided Root the phone which resulted in a lost IMEI, injected it back in, still no signal and still the phone was still burning up. Long story short I just eventually just ended up taking it back to Tits-Mobile.

What worked for me was turning off lte, leaving at max 4g. My signal went from half to full.

Hi Sam...thank you for replying.
My Note doesn't overheat anymore than usual. It's operating nice and cool. I don't stress it out much...just the usual email, text, phone, web...and the occasional Candy Crush.

Gosh...that's the first thing I did....setting ===> mobile ===> select 4G/3G/2G (not LTE)....but to no avail
I even did the *#2263# and select WDMA ALL...as well, but no luck either

many people I've known all have experienced the same shiiiiiit from tmobile
i think tmobile is playing game on its users
tmobile knows where we live and reduce signal ....tmobile knows at home we gonna jamp their bandwidth ....cause we're on unlimitted plan
let's dump tmobile and go for Gosmart

Is that possible? I'm on the $70 PrePaid unlimited plan. There shouldn't be any throttling.
When I do take my sim out of the Note 2 and insert it into my wife's HTC One at home, I do get full bar speedy connection.
Perhaps, they are throttling base on the IMEI of the device, rather than, sim. That's just pure speculation on my part.

mine is on $70 pre-paid as well...but can't watch Youtube without having buffering; annoying and embarrassing
my coworkers are on Gosmart $45-plans and watch movie online just fine.
My N2 all test speed @ 20Mbps ....but it's just for show; there is no use.....cause when I tried to download a file just 40Mb....it takes way too long relatively to its speed test.
I think the name Gosmart is realy "go smart"
