bad reception on sgn

I am on att wireless
I have noticed that in a low service area i get none at all.
However my wife on her iphone has 1/2 bars and my bro on his atrix also has 1/2 bars.
Anyone else having similar issues?
12/7 Update - More information on what I have attempted
Setting APNS for 4g on ATT
getting correct 4g data plan on account
New Sim cards
Replacement Galaxy Nexus
Different Roms
Stock Restore Rom
restore to default and install nothing
different radio
update to 4.0.1
Once the signal drops to almost unusable levels , the only way to get it back is either reboot the phone or toggle airplane mode. After that the signal returns to a solid 89-93 DBM. After roughly 30-60min it will then drop and I have to toggle it again. All other phones in my location have no problem including my iphone 4s with the exact same sim card.
I am in a decent location for signal. On the nexus reboot its at -89 dbm , my iphone 4s is at -87. The iphone stays that way and the galaxy nexus over time drops to -105 to -111.
Still no conclusion.

I only have problem with Wi-Fi where the reception is considerably weaker than any other device just around it.

Bars mean very little, as devices have their indicators calibrated differently. You should be comparing signals, in dBm for a meaningful comparison.
The acid test, of course, is whether you can make and hold a call, and or send/receive data.

Yeah kind of hard to gauge from bars. Nokia and motorola are known for excellent reception. Samsung not so much. They do seem to be improving on all fronts though, including wifi and gps.
Sent from my samsung gt i9250 which is in the wrong country.

I havent got too in depth with testing but its simple to see there is an issue. Everyone around me can make calls and i cant. Cell standbye taking up battery life as well and has been out of signal for a while

I'm seeing a similar issue.
When I have 2g only selected, I get 2 bars -98 asu 7. When I have it deselected I have no bars and signal is -111 asu 1.

Well ive had similar issues
Today I wiped phone and came back to initially 4/5 bars and download speeds of 4 down 1 up.
Then after about 10 min , right back down to 1/0 bars and 800 kbps down 200 up.
popped off back cover and then pulled sim , reset sim and then reboot. Again it initially came back with 4/5 bars with hsdpa. Again about 10 min later back down to 1/0 bars and a -113 dbm reading,
Then oddly enough i was in the status screen just watching it hover around -113 to -105 , it clicked to edge full 5 bars , then came back to 3G 4 bars and now at -93 dbm.
Does this sound at all normal? I havent changed location more than a few feet through all this. My wifes Iphone seems to be having 0 issues right next to me.

just watched it do it again.
Was at 1 bar went to 0 , got stuck on -113 dbm for about a minute or 2 clicked over to edge-2 -87 dbm then back to hsdpa -93 dbm
:/ i got no clue at this point
there is a video showing some of the issue

Is this at home or a place where you frequently are? If so, I would do one of two things (provided you want to keep the device):
Write an NFC tag that you can tap on your way in (and presumably on on the way out as well) that would switch you over to "2G only" (which it seems gives you a better signal), and back to 3G/3.5G on your way out the door. or...
Either write yourself, or wait for one to be written, a kernel that will throw more power to the radio (at the expense of battery life however- but if you are constantly searching for signal your phone is probably wasting a ton of battery right now anyways)...

ya i am at home.
My wife consistently gets 3 down 1 up on her 4s.
No one else seems to be having issues , perhaps mine is just defective?
this is what happens when i lightly grip phone

Maybe, but I can't think of a way to reliably test whether it is defective or not. My Samsung phones have always had lightly weaker radios than my HTC and Moto phones, and my sister's iPhone, so I will wager that it is just that in the name of battery life the radio is under-powered, which can be changed in the kernel. I was in a similar boat back when I was on T-mobile (right on the edge of service), and luckily someone had posted a custom ROM for the G1 that routed more power to the radios, and gave me just enough to hold a signal and use my wifi for data. Whatever that kernel in that ROM did, it gave me about 10 dbm difference. You might want to throw a request in the development section.
you can also try exchanging the device (if ever unhappy at all you should try to), but I am wondering if it will actually make a difference. Do you know someone with a recent Samsung phone like a SG2 (not LTE/Skyrocket) or maybe one of their Windows phones (I don't know what radios/speeds they use), to see if it gives similar results?

Ya , i was at my brothers house yesterday with no service at all.
My bro had an atrix with 1/2 bars and service.
my wife had an iphone 4 with 1/2 bars and service
and my sister in law had a galaxy s2 with 1/2 bars and service as well.
I had 0 at all.
The odd thing is , every time I reboot my phone it holds on to 4/5 bars at the location im at right now for a good 10 minutes , then flatlines.

what APN are you using? Use the same APN settings as your Sis-in-law's GS2- when my Nexus first came I noticed the APN did not match my Atrix and it would not hold an HSPA+ signal for long; I changed it to match the Atrix and speeds/holding towers has been much better. Try the APN thing.
The GN and GS2 would have the same radio chip (I would imagine), and be set to draw the same amount of power by the kernel. If the APN thing doesn't work then you might want to consider an exchange I guess, maybe it is defective
The fact that it flatlines AFTER 10 minutes (presumably after all the syncing is finished for the various apps and services) is suggestive of a sort of "demand" model- like maybe the device amps up the radio when it knows there will be a lot of need, then scales back when demand is less- or over compensates at first, then under compensates later after some sort of calibration? The ten minute thing sounds odd, but sounds like something software/firmware/kernel-based...
[Keep in mind that there is much speculation contained in that advice, the true test for defective or not would simply be another GN at the same location- as that is unreasonable we'll have to speculate. Also, if your sis-in-law comes back over, check her phone status for her signal strength (not bars but dbm and asu) and see if it matches yours. The bars that you see are a software representation of those two numbers, and can be modified to under represent the actual signal.]

I am using the default cingular 410 apn
ive been reading that if support put a 4g data plan on my phone that it could potentially cause data loss. Is that correct?
also changed to 2g only for now and have 5bars -81 dbm constant.

Not sure I follow, if AT&T made your data plan a 4G data plan, it would interrupt your service?
I think you are asking if changing these APN settings will trigger something at AT&T, and they will "bump" you to a 4G plan- in which case I don't really know, I had to jump onto a "4G" plan when I got my Atrix. I think it would never reach that point though, when you set up the new APNs, that step where you touch the dot to select the HSDPA APN, it would default back to your cingular 410 apn if it were not able to connect (via SIM provisioning or whatever). If unavailable it wouldn't be connected at that rate to begin with.
How old is the data plan you are on (is it prior to the tiered plans)? If you are worried about the connection (APN) not matching the SIM, you could request a new (4G) SIM. Maybe stop in your local store, or call customer service and tell them you are thinking about buying a 4G phone, your friend's brother's uncle' pizza delivery boy's nephew has an unlocked phone you could test speeds with, could they switch out your old SIM for a newer 4G one to see if it will be worth your while at your house, then just pop in that new SIM, change the APN and away you go? (Or to be even less complicated take your old phone in with your old SIM, and just ask for a new SIM card, that yours isn't working right, and it should be a new 4G (not LTE) card...
Well, at least the phone is usable on the 2G band for you, and will save a lot of battery. Meanwhile we'll try to get you connected to an HSPA+ tower.

thanks for all the help really appreciate it.
Anyways a few things have happened since I last posted.
I had an iphone for the last 3 years. I went into ATT last week and got a normal 4g sim card in advance. Today I called my buddy who is a manager at a corporate store and he checked my account. Found that the lady had the wrong data on it. He ended up setting the sim to the 4g plan etc (which is unlimited)
I was able to add the ATT HSDPA apn and successfully connected to it. Prior to this I actually installed modaco's rom and restored everything.
At this point I am getting consistently 3 bars in my house (which is more than my wifes iphone 4s) on 4g.
Seems to be working much better now. The only other issue that remains is when I turn on WIFI. If i turn it on the cell reception goes to 1 bar or sometimes 0. I dont have the exact dbm values right now unfortunately. Calls and text still seem to go through however. Is it possible the wifi is drawing power designated for the radio?
Thanks again !

Awesome, glad it worked out.
And possibly yes, depending on how the kernel relegates power wifi could "commandeer" a little from the cell radio, and reduce the dbm just enough to reflect in the "bars" algorithm.

perhaps a new radio will eventually come out that I can test.
either way seems to be at least in service now , signal definitely drops when i hold the phone but as long as I can make calls it should be fine.

in the meantime i'll suggest using the open signal widget https://market.android.com/details?id=com.staircase3.opensignal&hl=en
which will tell you the real reception in the phone, and see what you are getting behind those bars
don't expect to make a good call when the signal drops to -90 dbm and above
and if you have multiple phones like i do, then you can compare if other phone in the same spot, connected to the same tower, is having higher or lower dbm than SGN
for example my Nexus S had worse reception than my Milestone XT720.... go figure

Thanks I will try it out,
Overall i dont think the issue is fixed at all now. Went to bad and signal dropped all the way again. Stuck at -111 dbm. I held the phone i saw it switch to edge 5 bars and then click over to H 4 bars.
I really believe its some kind of software thing. If I cycle airplane mode on / off I get 4 bars (unknown dbm but its working) of 4g service. I know the service is here and working as my wifes iphone is fine but something is causing it to not hold the signal and eventually drop and not recover.
Makes no sense
Downloaded the app ,
Was at 42% signal strengh, I noticed when I picked up phone and lightly held it , it dropped right on down to 5% and got stuck there. This wasnt death gripping it either , barely holding it. Does anyone else have this issue or is it just mine? I know all cell phones have this issue but this seems excessive , worse than my iphone 4 ever was. I then cycled airplane mode again and signal strength went right up to 65% again -89 dbm

[Q] * HELP! * One X Keeps losing Signal

Hi guys,
After weeks of waiting, i finally got my HTC One x today.
But there is a problem.
When i put my Sim Card in , I get around 2 Bars of signal, and then it goes away and the cross comes over the bars, then the phone says ' Preparing Sim ... ' , then the 2bars appear again, then they go away and the the phone says ' Preparing Sim ... ' , and on and on and on and on again!
I am extremely sad and dissapointed. was really looking forward to this phone.
Can anyone help with this issue?
P.s. the phone is stock and untouched.

I had problems with a cut mini-sim. Got it replaced with a proper micro sim and all is fine.
M.

For the people who have cut there SIM card, make shure you are using the new generation SIM card. Cutting a old generation one can bring issues!

That's weird. My one x is getting signal where my sensation had none!

Woke up today, no signal and sim couldn't be found.
Was fine last night.
Either T-Mobile deactivated it because they have sent me a new micro sim, the phone is a dud or somehow the cut sim decided to break itself over night somehow.
If the new sim doesn't fix the problem, the phone is going back and ill just buy something crappy to tie me over till GS III.

It has good wifi reception, I'm getting signal in places where I'd have to wave my hands around in the air before. But the gsm signal is really annoying me

none of you have my problem . My is faulty. no reception at all.

Mine jumps from H 3 bars to G (gsm), back and forth. Very sketchy signal.
Using a new micro sim I received today.

Hmm.. I'm using a cutted SIM and it didn't show any problem. Instead, I am getting signal at dead spots compared to my DHD in the past. Weird..

Got a microSIM sent out by my provider. Works fine. I'm getting even better 3G reception than with my Desire S. Sounds like a faulty sim to me.

Strange behaviour you guys are having there. My signal strength on the same telco has been improving switching fr DHD to HOX. Some places with weak signal reception those day in DHD (with 1 or 2 bars) now I could get 3 bars.
Most of the users in my region do not faced such issue, we are seen the coverage is jumping fr H to 3G back and forth rapidly, which we believe is due to service upgrade (cos have been notice such behaviour even in DHD)

I have exactly the same issue with you.
Actually this is my 2nd OneX, the previous one has "yellowish display", but there was no signal reception problem.
After replacement, I found the new one has the same problem described by you. It changes between 3G<->H quite oftern, and I found that mobile radio goes off very often, but then it's showing me "preparing SIM..." and signal comes back again!! Since my SIM on the previous OneX has no issue (at least I used it for 4 days already without this problem), so I don't believe my SIM is the root cause (and mine was the official micro SIM from telecom).

Yes, I agree that for some location that normal phone doesn't have any reception signal, OneX does have signal. And it also changes from 3G<->H quite frequently.

I'm having this issue too. It seems when the phone is trying to talk on 3G instead of H, it doesn't work. So, everytime the signal switches to 3G, I lose data. I still haven't been able to run a successful Speedtest.NET test on the phone.
Anyone have any ideas?

Also gave my HTC One back to supplier. Signal issue became so bad that i had almost no signal.
I found that when i was in a building my signal disappeared. Hold your device upside down and you get better reception. Also made a benchmark test when I got the phone and it score 4700+
when the signal issue started i did a test again and it only scored +/- 3700. Must be hardware. I tried Hard resets and nothing....
Going to be a long wait as I'm in Namibia in Africa and phone was ordered in UK. But overall just an awesome phone !!!

poor signal htc any way of boosting it

i have had my phone a week or so now battery is getting better but the cell signal is really bad compared to my last device which was a n8 is there any solution or fix??

Ive a X on Orange and I have to say it seems to struggle to get a good Orange signal in areas I'm sure used to be very good on my sensation.

I am also with Orange. I am finding the connection very eratic. Quite often there seems to be none or one bar, then it will jump to 2 or 3, then drop to none again. Anyone else seeing this? I know there is a thread on the WiFI dropping at times.

plz report it to HTC. I'm on T-Mobile (UK) and having same problems. The more reports they get the more likely they'll take note.

Does the signal issue have to do with the way your holding the phone in low signal areas?

I'm on T-Mobile UK too which now uses Orange masts. Anytime it switches to an orange only signal I only get a G signal. I've turned off data roaming and all is well.

I've found similar issues but also I can't get it to report a signal better than -83dbm. Anyone else notice this?
I'm hoping the 1.28 update has a new radio.

Did you try another sim?
Also are you using a legit MicroSim or you cut your old sim into a MicroSim? This causes bad signal.

Try to avoid covering the lower left corner with your hand as it will greatly attenuate the signal. Not to the same extent as the iPhone 4 dramas, but still quite noticeable (2 bars).

Legit microsim direct from the network.

I can have my phone on the desk and I am actually seeing the wifi strength and the mobile signal fluctuate between 0 and 2 bars. It does that most times I take it out of sleep mode, it does this for about 60 seconds then stabilises. Happens almost every time.

Just chatted online to HTC and he was quite quick to say - faulty fone. ask for replacement.
But I have heard from a few people locally, all on orange, who have said they have had major reception probs on orange in last few days, dropped calls

update
Orange are blaming it on local cell issue, didn't listen when I said its not just local, but then again she did ask me to take battery out of One X !
Anyway, she got me to go to GSM only until local cell fixed. Am I correct in thinking that this will not use HSPDA now though ?

Do you mind me asking exactly what you asked htc? I'm finding that my desire is often ~10dbm better than my One X

Just told him I've noticed significent drop in signal from Sensation, lots more T-Mobile log ons too. He quite quickly said get fone swapped.
Orange reply as above, blaming local masts.
The signal seems to jump from one extreme to another either full bars or one bar only.

me in singapore here having this problem too...
and also using legit microSIM

im on vodafone and today noticed that in an area where reception is usually fine, i had nothing.
... anyone know if this could be solved by a radio update or is it perhaps an unfixable hardware problem?
got the flickering screen too... seriously thinking about ditching htc, but i hate touchwiz and not really sure what to go for... maybe just go backward to a sensation XE.

Installed the 1.28 update last night. Signal is now much much much better. I Don't experience any of the above anymore!

jaspabt , are you using a branded or unbranded HOX on orange ?

Loss of signal, no auto reconnect.

I am having an issue on my One X (unbranded and unlocked) with the signal vanishing and not reconnecting unless I force it. I was wondering whether it effects all networks or just networks that use more than one carrier. Three has its own 3G network but it uses Orange 2G signal. I also saw a thread with the same issue on T-Mobile / Orange which is also dual carrier.
I am wondering whether it is the switch between these networks which is causing it to lose signal and not reconnect.
I have had several instances where my signal has an R next to it as if it is roaming, this would be when it is connected to the Orange 2G network, I never had this problem on my Desire HD or Sensation.
Does anyone know of any issues on Vodafone or O2 regarding signal loss or is it just networks which use multiple carriers.
My One X is stock and bootloader has not been unlocked.
Thoughts?

Are you still on the 126 SW?
As your unbranded then you should be able to get the 128 update.
With 126, my Three handset recieve level was about -88 to 91dbm.
With 128 its now at -75dbm in the same location.
Most, if not all of the roam to Orange has now been disabled, remaining where there is no Three signal at all.

No I have upgraded to 1.28, unfortunately I am still in an area where it does switch to Orange 2G signal.
It seems to hang on to 3G until I have virtually no signal, then goes to no signal and doesn't reconnect unless I force it. It seems to mostly happen when I put the phone away on my pocket so I dont notice I have no signal until I check my phone.
I lost signal today and to test the reconnect I left the screen on and I drove about 20 miles through large-ish towns and it didn't reconnect once, had to force it when I got home.
Not sure if this effects single carrier networks, O2 or Vodafone?

Have you had the same issue with any other handset?
Are you a new customer to Three and this is the first you have seen of this?
Reason I ask is when I was thinking of going to Three for my main phone, I tested with a handset I just used for tethering off the one plan.
I drove out of town to an area where I guessed there would be no Three coverage.
The signal hung on for ages but when it dropped I made a note of where it dropped. After a few moments the handset went over to Orange 2g. I then drove back home. I must of drove at least 5 miles past the point I noted earlier before the Orange signal itself dropped and had to force the handset to Three myself.
This sounds similar to your issue and was with a Desire S….but you say you didnt have this with previous handsets. All very strange
Steve

I've had a Desire HD and a Sensation both on Three and never had issue on either of these.
There must be something different about the way the One X handles the switch of signal, or maybe it's just faulty.
Might try some other SIM's from other networks, if that doesn't work I'll get a replacement.

I'm on three and it never seems to switch to gsm just looses signal all together and takes ages to reconnect once I move location. this is a proper pain I've had the phone replaced three times changed sim still not got better I'm thinking its the radio version on this phone or some software related issue.

If you're phone is from Three you won't get the update until Three release it.
I did see on another thread that Three won't be releasing 1.28 as HTC are currently working on the next update. Don't know how true that is.
My phone is unbranded and unlocked to any network, which is why I got the update.
Think I'm going to get a replacement and see if that's any better, hope it's not a general issue with the one X having lower signal.

If you dial *#*#4636#*#* on your phone and select phone info you can select GSM only which is 2G, this really improves signal but because it's 2G you are stuck on really slow data speeds.
If that is the case and you've had 3 replacements, maybe it's worth holding out for the next update to see if that fixes the problem.
I'm a little uneasy about returning it for a replacement as I don't have any other problems with it (bad screen seal, banding on display or yellow display) I may end up with more problems with a replacement.

Is any chance change three rom on factory rom?

I had similar issues to what you are describing with yours on my original unlocked/unbranded HOX on T-Mobile. I had issues on top of the ones you mentioned where it was also saying I had a signal and had appeared to lock up and would just drop the mobile network and say at the bottomg of the screen "preparing sim".
Most the time I was stuck with putting it in and out of airplane mode to make calls, only for them to drop or fail all together.
This was on both 1.26 and 1.28 FW. In the end I took mine back and swapped it and the replacement has been perfect since. so it was without doubt a hardware fault in my case!
Good luck solving your problem, but I would suggest taking it back and getting a straight swap.

You can't change you ROM unless you unlock the Bootloader at HTCDev and this will void your warranty with HTC.
Three will release an update eventually, and 1.28 is no better signal wise for me than 1.26 was!!

Interesting, I too had the Preparing Sim message until I got a new SIM from Three, this seemed to fix this message but I am still having Signal Problems.
I think I'll follow your lead and go for a replacement, I have to use Airplane mode to force the signal to reconnect as well.
Thanks

I can confirm I have these problems. I'm on three but the phone was from Dialaphone and with orange but is unlocked. I have exactly the same problems as those been described. This is a very irritating problem that makes me miss calls and texts in my poor 3 signal area.

I think you're best off to return it for a replacement, that's what i'm going to do. Hopefully that will fix my problem and not create any more!!

I have the same issue on my device. On my 2nd replacement and its still the same.
No problems with my iPhone 4S.
Hopefully a radio update will sort this out.

I think it might depend on location, in some areas the 2G signal (Three use Orange network for 2G) has been turned off. In my Area (South West England) I still have access to the 2G GSM Signal.
Obviously Three save a lot of money from turning off GSM and not paying Orange to use their network.

[Q] GSM Signal has recently reduced

In my house i have ALWAYS had FULL GSM 2G signal and if i go into the kitchen i could get 1 maybe 2 bars of 3G
But since yesterday that is not the case. Now i am only getting 2/3 bars of 2G (-97dbm) and occasional drop outs in signal all together - very annoying
What can be done?

It might just be a fault with your nearest cell tower so temporary. Do you have another phone you can try and use to see if that works as you expect? This would point to the phone itself being the problem or not?

What network are u on? I'm on orange and I only get 2-3 bars when network switches to orange-T-Mobile but when I manually set network back to jus Orange I got 4-5 bars

Thanks phil, I think u may have been right. I downloaded network signal info from the market and it was showing that I was connected to a mast about 1.8 km away and today my signal was back to normal... After checking with the app it showed I was connected to a mast around 1.2 km away so perhaps some maintenance was being carried out in that tower
