I did search and I was sure there'd be a thread on this, but I frankly couldn't figure out what to seach for and got no hits. My Tilt makes the mistake of showing an "E" for Edge instead of 3G sometimes. My data rates seem to indicate that this is not just an icon mistake but an actual problem with the radio (though I am still not sure about this). This is all the more strange because, where I live, the telcos skipped edge and deployed HSDPA directly so I have no idea where this phone is getting an edge signal from. I have my Tilt next to a N95 and the N95 is showing 3g and getting faster transfer rates.
So my question is, which of the roms (if any) will fix this? Thanks!
I've had similar problems on my Tilt with every rom I've tried so far. The download speeds vary wildly, and the icon constantly changes between E, 3G, and H. Sometimes it changes every couple of seconds, even when standing still, in a typically good connection area. My GPS connection has similar problems. It's constantly jumping between various satellites, and never seems to hang on to the same one for more than a second.
I really hope a radio upgrade fixes these problems!
Thanks for the reply! That is too bad . Guess I will be sitting tight for an update .
Did you guys call AT&T about this? If they don't know they won't bother trying to fix it...
My Tilt stays on 3G or E, which ever I choose, very solidly. It might be just your area is a little weak on signal, which is a fix done at the towers at your location. So, you'll need to let AT&T know.
I don't know if this is reLated. I do not have 3G in my area but only EDGE. However I find my TyTn II uploading and downloading data at only half the rates to what my HTC Touch can manage. While my TyTn gives me around 100kbs the Touch can manage 200+kbs. I have tested repeatedly by swapping SIMs between the two. Could this be a radio problem?? Can I bank my hopes on a future ROM upgrade??
same issue here. I had to reboot few times and hope for the best. I was in San Jose ( EMC / Yahoo Campus) and was getting EDGE but I rebotted the device few times and it finally picked up 3G.
Been using this rom for a few hours now: http://forum.xda-developers.com/showthread.php?t=341886, and is seems to have fixed my problem. You should give it a try.
BTW, I got a Tilt as a gift but I have never had AT&T service. I am still puzzled as to where the old ROM was finding an Edge signal, as my carrier confirmed they never implemented Edge, just straight from GPRS to HSDPA.
I wanted to start this thread to discuss making and receiving phone calls on AT&T's 3G network. I find that making and receiving phone calls while connected to 3g or HSDPA is very unreliable on my Fuze. The phone seems to always connect to H whenever there is any signal available, even if the signal is very low and unreliable.
I will sometimes recieve a call while connected to H and the person cannot hear me at all. I'll look at the phone to see that the H signal strength is very low. Instead of smoothly switching to Edge, the phone completely loses signal and drops the call. After having no signal for around 10 seconds, it will then reconnect to Edge and have 2 or more bars of service. Why couldn't it just switch to Edge without dropping my call? Any why hang on to an HSDPA connection if signal is unusably low?
I see other AT&T customers with 3G phones (Bold, iPhone) and they don't seem to have this same issue. Their phones can remain in 3g mode and work just fine. My only choice seems to leave 3G turned off, but switch it on when I need a fast data connection (a terrible solution).
I used to have Verizon and they just connect you to both their 3g and 2g networks at the same time, you can even see 2 signal meters on most phones. They use the 3G (EVDO) for data and 2G(1xRTT) for voice or data, when 3G is unavailable. Why can't my Fuze do the same thing on AT&T? Clearly, 3G doesn't penetrate building as well as 2G and the phone needs to use both, seamlessly, to work properly.
Just for background, I am using a Fuze with the latest EnergyROM and Radio 1.14.25.35 and matching Rilphone.dll. I have noticed this behavior with other roms and other radios also. I can't remember how stock worked since I haven't had it in such a long time.
Does anyone else notice the same behavior as me and does anyone have any ideas on how to improve the way the phone manages 3G vs Edge during phone calls?
Thanks in advance for anyone who can help me understand and resolve this problem.
different radio
Drop into the ROM section, hit the radio thread. I found better luck dumping the stock radio on the Fuze, and installed a different one.
Any particular one that you recommend? Ideally, a radio that doesn't use 3g unless signal is reasonably strong would be best. Ive tried all of the official Fuze ones without any change in the behavior I described at all. Based on your signature, it seems you are currently using the same radio as I am...

I found the newest Xperia radio (1.16.25.48) to be very satisfactory as far as signal strength goes - in fact I had more bars of 3G and dropped a lot less calls because of it. However, you need to be Security Unlocked to flash your phone with that radio. The only problem with the Xperia radio I had was the pitiful GPS accuracy.
sopranos16 where are you located? There are a few cities where users have been complaining about the 3G network. NYC/Northern NJ and San Fransisco are two that come to mind. Check on howardforums.
I'm now using a Fuze because AT&T shipped to to me to replace my Bold which will drop 5-15 calls a day in NYC. I don't believe it is a problem with the Bold, I have other lines with 3G that have problems. But this is the solution they offered so I'll try it.
You cal also check the at&t support forums as there are plenty of complaints there too. I just got the fuze and haven't really tried it yet. See what happens on Monday.
I'm located in central New Jersey: Monmouth County. Edge coverage is pretty good but 3G tends to always have a weaker signal strength and occasionally drops out, especially indoors.
Well the first day in lower Manhattan and not one dropped call. I'll let you know what happens later in the week.
bump
soprano, did you try the xperia radio? Let us know, I have had this issue for a while now...and your explanation was on the head.
Think I may just go ahead and security unlock my phone.
Hello One-S users!
I recently got myself an unbranded One-S here in the Netherlands. I came from the LG 2x that I've had since the day it was available. Been experimenting a lot with different ROM's and BB, with different results across the board. Overall though the 2x has been a very nice phone to have and use, albeit not with the stock ROM's. Reception has been very good, probably the best of all the phones I've owned.
And now there's the new One-s... I've been using it for a few days so I won't go into details on battery life, user experience and all that stuff that needs a few days before making any useful conclusion. Except for reception!
I live in a particular area where there's very bad signal and only two towers in the whole area. The One-S seems to really struggle to get AND keep connection to the network. Actually, when used indoors (at home) it is impossible to get any signal at all, whereas the 2x and my girlfriends iPhone4 have no problems at all. Not great reception, with breakups during calls, but at least the work. The One-S doesn't. I've been seeing this behavior outdoors at other locations as well, around where I work I have had no reception issue's with the 2x, the One-S shows really spotty reception.
I'm on the latest OTA which is 1.78.401.2
What's your take on this, do you have any reception issue's?

I had a T-mobile branded One S (Gradient Blue) and the reception was horrible, so glad I got myself another GS2 (t989)
I'm experiencing same issues of reception on an unbranded EU phone with 1.78. 1.53 was worst!
I tend to have signal but no data, I tend to have signal in the notification bar but no actual signal.
I have many issues which weren't here in my old desire!
MicroSIM was replaced twice with no real help - It's the phone to blame...
Poor reception
I also have same problem. I am in pakistan using Telenor and phone is Tmobile UK unlocked.
It may work to disallow some energy-saving settings(of the ril) in the build.prop, however it brings risk to do so:
You have to know how to tweak the file, and get ready to re-flash the ROM/RUU in case of half-brick caused by bad tweaks.

That sucks! It is a great phone. Reception has been flawless for me. I have a TMOUSA-branded One S.
the worst reception ever...
well I lied a bit - as most of the time I'm getting no reception at all;/
sometimes around 60-70% of the time with no signal (when I click the cell stats in battery meter) and often when picked out of the pocket the phone is showing NO SIGNAL warning for one second...
Unlocked HTC One S, UK version, ceramic black, bought beginning of April
I had this problem from the start, but was hard to prove to get a new phone replacement, as when it does have good reception when signal coverage is great - with 10MBit/s download 3G speed which was amazing compared to my Desire Z (max 4MBit on 3G). The problem is, signal reception fluctuates a lot to a point of loosing it...
Wifi is affected as well, for example after a fresh reboot the Wi-Fi is at full speed, but give it an hour of mobile usage and it is at half of its performance. Wi-Fi isn't that critical (although I do not have signal in my garden where my Desire Z or iPad doesnt have any problem with my home wifi!) but the weak radio is!
I wasn't scared so much as I thought an update will come, and it did, so I have updated radio to 0.16 (1.78 RUU) from 0.15 (1.53 RUU) in a hope things will improve, and they did for 1 day - then I realized it was a placebo effect what I'm seeing.
In network stats I am mostly on -97 to -107 db in signal strength with 0-5 ASU, and when I have -93db I can celebrate! (which is considered pretty weak on my other android phones)
Researching this problem led me to believe it might be a software bug as well, as it varies - when you're doing a phone call, signal strength is simply stronger, you're out of a sudden see more ASUs and are say on -92db. As long as you hang the call, you're at -101 db again, soon after you can loose the signal when you're in placed with weaker coverage (park, too many in London).
Then I have places where I am absolutely unable to make a call, and the other day I do have 2 bars there and I am able to call without a problem.
Then the other day I can try 10 times and no chance - no signal, immediately rejected from a call app, can't even call voicemail.
The top icon notification is 'mad' most of the time - showing full strength from time to time only to fall to 1 bar (or no bar) on 80% of the time.
I would welcome some idea how to prove this thing to a seller to get a replacement, but as I said, if One S sees 20+ more ASUs (city coverage is great), you don't notice this thing and it can work flawlessly.
My conclusion is that HTC One S has only problem when the signal coverage becomes weak and it can't properly get hold of it like other phones do (Samsung Galaxy S Plus, for example, is ten times zillion million better than this - having much stronger signal when covered with pillows closed in a stainless steel box ;-)
Should we start writing the serial numbers here so we can see which batch of HTC One S phones is bad?
P.S. The USA T-Mobile update 1.83 is promising some fix to signal fluctuation - I don't know it this would help european version, even if it would not fluctuate, it would still be weak.
P.P.S. Switching ON the 'best wifi performance' haven't made a single difference for me, neither for radio strength nor in wifi. The only difference was big hit on battery life.
I know exactly what you mean - had it the same!!!
Apparently there is a solution which is not hardware related:
There are network providers that doesn't support the signal fast dormancy as this phone tries to use. As a result, the phone disconnects from the service provider and tries to reconnect which takes several minutes.
In order to solve that until HTC will do it (if at all), you need to root your phone, get into build.prop file and then change the line ro.ril.fast.dormancy.rule=... to be ro.ril.fast.dormancy.rule=#.
This is thanks to jh787!
It seems to help me.
I'm in the Netherlands too, with an unbranded device and facing same troubles. Got my device lately with 1.78.401.2 preinstalled.
The reception is compared to my HTC Incredible S really bad.
I becomes irritated too by the FM Tuner recepetion. If you're moving on bccycle, car, train or bus the volume is getting up and down, up and down. And lot of areas I can't listen at all to the radio stations I could with the Incredible S
don't want to root just yet...

Thank you, you probably mean the thread mentioned by jh787 at the bottom here:
http://forum.xda-developers.com/showthread.php?p=26923454
- it might fix the issue, the problem is I've tried 2 different mobile providers with same results and today I bought O2 PAYG microSIM to try the best (signal wise) London mobile provider to see if the fast dormancy is the problem. I don't want to root the phone yet as if it won't help the warranty is void. I'll report later.
- there's another tip in that thread
jh787 said:
also changing the following line to look as shown solved my no network issues when i was in areas of weak reception
ro.ril.disable.power.collapse = 1

I don't have root yet, but just checked /system/build.prop file using Solid Explorer and I have this value already properly set as others have mentioned (1.78) but the phone still has weaker signal when idle and stronger when having a phone call.
Code:
# For HSDPA low throughput
ro.ril.disable.power.collapse = 1
As I understand this should be '#' instead of 1
Code:
ro.ril.fast.dormancy.rule=1
comparing to jh787 build.prop I am no wiser, as he's still at older 1.53 OTA and seems like T-Mobile branded phone.
I'm already on 1.78, checked his 2 comments and also found that the power collapse is 1 already. The fast dormancy I did change to # and believe me, after 6 weeks of screaming on the phone to be a phone, other than a great looking mobile computer, I'm using it flawlessly as a phone too!
Root is reversible via RUU and for me needed until HTC will provide an update which will either disable the fast dormancy or enable a switch to control it...
Ive had 2 One S's since launch and both of them have had appalling signal issues, Im on Vodafone UK and believe its their network at fault.
But i see here a range of providers and still crappy signal. I was thinking of cancelling my Vodafone contract and taking out a new one with another provider, As i really like HTC..... But after reading this thread im having doubts !
Im beginning to think the safe option would be to leave HTC and Go back to Samsung, And try to get the S3 !

Are you rooted already?
If so, try the build.prop change I mentioned before...
Im rooted, Ive ran every custom ROM, Ive flashed every radio, Ive done everything possible, Nothing works.
Ill give the build.prop edit a try later. not expecting much tho.

Really? disappointing!!!
Then you probably got something else then - is the same carrier different phone have better than you on same locations?
Hello guys and girls,
after experiencing some GPS problems (loss of signal on the road and/or late fix) I did the fix found on youtube (Where you place a bit of paper/tape under the GPS antenna contacts). It worked just fine, my GPS fix is now happening faster and I did not lose the signal ever since. But I am now facing some (weird?) problem: My GSM connection (GRPS, EDGE) is really really bad. In my room I don't get any signal at all, outside I get like 1 out of 4 bars of signal strength, but I lose it after a few seconds. I normally have 4 out of 4 bars in my room. BUT: My 3G connection works fine, 3G, LTE, same connectivity as before.
My friends phone (same carrier) does get the full GRPS/EDGE connection in my room, so it's not the carrier having problems. I didn't do any updates or anything in the last weeks. It would be a huge coincidence, if a software bug happened while I fixed the GPS problem, so I assume it's a hardware related thing?
How might I fix that, what possible solutions are there?
Tried the following so far:
Restarting multiple times, with our without airplane mode
Re-inserting the sim-car
Switching between LTE only, GSM/LTE, GSM only
Flashing new/other modem
Replacing the speaker/antenna-module
-> nothing changed
out of sheer curiousity, and after reading your post, im stuck wondering.. why do you want or need your gprs and edge connection when your 3G/LTE is fine? data speeds are very slow, and drain lots of battery using anything internet or download related..
Yeah, sure, 3G/LTE is better and coverage is really good where I live, that's why it's not an emergency for me, but it's very important to get it back to work properly.
I know at least 2 situations where I really need GSM (GPRS,EDGE):
1) At work (huge metal building, no 3G/LTE, only GSM) -> I can't call, text or do anything with my phone (don't worry, I am allowed to do so and no, there is no WiFi)
2) On the road, especially the german autobahn has large areas where there is no 3G/LTE coverage, so I can't use my navigation-software properly and can't respond to calls or whatsoever
So all in all: GSM in really important for me. Please help me. :crying:
ahh.. I see.
and your GPRS/edge was fine before the GPS "fix"? maybe something got loosened?
Before I did the fix it worked perfectly fine. Directly after I did it, the gsm was gone so I figured that I somehow damaged the antenna. But since I replaced it and nothing changed I am not sure what to do now. Are there other antennas, are there other modules that influence gsm, that I might have damaged or loosened?
That's what can happen when you tinker with guts of your phone. You risk damaging or messing it up. Sorry, I don't mean to sound like a jerk.

Yes, dave2metz, I know. I was fully aware of that when I opened my phone for the first time to fix the GPS thing. But I am not here for moral advice.
Any ideas how I could fix my problem are highly appreciated!
Edit:
Just checked: The sim-card is not the cause of the problem either. I would really appreciate some good ideas guys..
No idea what I might try?
My best guess is that this is a hardware related problem. But how does one fix it? I replaced the antenna (the bottom thing), nothing changed. So that specific antenna was not the cause of the problem.
Are there other antennas?
Are there antenna-connections that I could check?
Any other hardware things that I might check?
Anything that might have lost the physcical contact inside the phone because of that GPS fix?
Could it, against all odds, be a software problem?
Please, I am really in need of a working phone. If I can't fix it I need to replace it sooner or later because GSM is essential.
If anyone can provide me with an idea or something that leads me to a fix, I will reward you (amazon gift-card or whatsoever).

Did you end up figuring anything out for this? I have something along the same lines. I dropped my phone and smashed the screen. I was able to get a guy to replace the screen portion of the unit, but immediately after I got it back it had no cell reception. Rebooted came, back thought everything was cool.
After a couple weeks I notice my phone has lost reception occasionally. It's now gotten worse, I used to be able to reboot it about 5 or 6 times and then it would randomly come back. I've even had it come back without performing a reboot on its own.
I ended up taking the whole thing apart, reseating everything after having a day and half span where I have been unable to get it back and boom reception came back. Thought it was his repair job at that point, but it has since dropped the signal again and I can't get it back. Yesterday even I was showing LTE signal changing from low to strong etc, but my network was still down as I couldn't perform a search, maps, or anything.
I have my phone apart again. I've checked all the connections over and over and wondering what else to look for or try to replace. True my impact could have damaged a component on the mainboard, but my phone works fine in all other areas. I could replace the antenna wires and the antenna/speaker module, but I'm not sure it just a reception problem.
My phone also boots into airplane mode when it has no signal, but turning it off does not restore the connection or anything. Rebooting it puts it back into airplane mode. *#*#4636#*# shows my radio is off. Thinking it's a short or something somewhere, but I doubt I'll be able to fix it in that case - at least without a mainboard?
That's my other question, what part need to be replaced for experiencing no network and its not the antenna or antenna wires? Is the mainboard? Sister board? Currently researching teardown as this phone is modular and I'm sure I could source the part off ebay or something.
Hi,
There's one antenna for 2G/3G/4G so I think if this problem was caused by hardware, it would affect overall connection to mobile network.
I think that this might me software-related problem but actually can't figure out which. Only thing I'm currently thinking of it that your phone has problems with connecting to certain GSM band. For example in Europe are 900 MHz and 1800 MHz standard for GSM.
Lower frequencies bring you better coverage. Your phone might have trouble with connecting to them and automatically selects 1800 MHz layer.
If you are able to get another phone with SIM of the same network provider, I recommend you to download any networking app and compare data about cells. Mainly CID number. It's unique identifier of each cell in an area.
If both phones are connected to same cell (CIDs are equal), you have to compare RSSI values. Lower means better signal. RSSI is defined as a negative number in an interval of <-51; -113>. So -75 dBm is better than -89 dBm. In one place should be difference about +/- 5 dBm.
Reaching slightly different RSSI numbers while connected to same cell in same place might mean that your phone really have problems with radio.
hey mate,
My wife phon is having the same issue 4G works, 3G sort of works, 2G nothing.
[Did the GPS fix on my wife's Nexus 5 (and mine) also]
swapped sim, used another telco same issue.
when into service menu did *#*#4635#*#* , click the 3 dots, select radio band - only see USA band.
While my phone had automatic, usa bad , usa band, japan band.
she is running stock rom with unlocked boot loader, I am on CM11 but doubt that should make any difference.
if I work out what is going on will report back.
nexus 5 3g 4g damaged
hello guys?.. my htc nexus 5 got wet and i notice the signal strength got lost. when i open it up i notice the lines on the antenna got damage. how do i repair it? or should i replace it with new one? Pls help !!

Hi. I am having the same problem. Could anyone find a fix for this?
My GPS was and is fine. I didn't do the gps fix, but I have replaced my battery and I think it happened after the replace...
Hello,
I have a problem with my OPO that has been going on for months now (I suspect it's hardware based? but not sure)
My opo can always connect to 2g network
My opo can only connect for a limited time to 3G/4G networks. If i change the network type, I get internet alright for about an hour or so. After some time or event (can't find a pattern), the phone is suddenly disconnected from mobile internet (even though data is ON), but my reception indicator is full. I also cannot place calls or get called: when I try calling, I get either a textbox "network unavailable" or the call attempt just ends on it's own without result. I'll call this state "fake 4g"
Here's what I have already tried:
-reboot, flash other rom, factory reset
-downgrade and upgrade TWRP back again
-messing around with 4636 (but i think i haven't tried switching to US band and back to EU - i'm from europe). Note: the interface shows precisely one cell tower when i'm connected to fake 4g
-going back full stock (flashing a version of cm prior to YOGPAS1N0) in order to update the radio. I even installed oxygen at some point
-pulling a logcat. However, this problem (other than the fact that i have only have a basic grasp of IT) is that I cannot exactly pinpoint WHEN fake 4g occurred without looking at the screen/placing a call. I managed to determine fake 4g came up between 4:55 and 5:46, which is still a heck of a logcat. In order to generate some logcat chatter, i've placed a few unsuccessful calls during fake 4g period (i've pinpointed those logs)
Does anyone have any idea as to the cause of this bug (not entirely sure it's hardware based because it works, well, sometimes...)? Or can anyone maybe tell me what to look for in that 50 minute logcat? I guess I can always have another logcat run in the weekend and check every 5 mins until i can spot fake 4g happening.
Note: I haven't opened it to check whether the antenna is plugged or anything (not that i would see much, i think). Anyway, i can always do it if need be.
Thanks in advance
I have been having a similar problem, the LTE range keeps fluctuating from zero to 3/4th to full from time to time, even when the phone is lying stable. Range appears well when on 3g. It isn't sim card based as iv'e tried various sim ,phone combinations.
Also i have noticed many topics appearing in the past few months regarding network issues ... some kind of a pattern ?
Ah yeah I forgot to mention that I tried the simswap trick too, to no avail.
So you're suggesting the hardware antenna might be of poor quality, that might be the case. If so, I suppose the antenna cannot be easily changed (ie incorporated in mobo or whatever).
Does anyone know whether antennae are prone to fail in general?

Nope.If there hasn't been anything that could damage the hardware,no.
Have you tried changing firmwares?

Even i am facing the similar kind of problem and posted my question here https://forum.xda-developers.com/oneplus-one/help/internet-issues-intermittently-unable-t3714911. One more thing to note is if you try tethering with laptop the internet works just fine (it happens with my device) . Even i have tried many combination with 4636 interface but i really can't understand the reason behind it.
Flash latest modem firmware... Then *#*#4636#*#* ..then on phone change signal to 3g only or LTE only..
Helped me from losing signal
