Problems with reception - ONE Q&A, Help & Troubleshooting

Hello.
Bought this OPO recently second hand. It sadly had an issue with connectivity. It has really bad reception 99% of the time, no matter where you are. Below -103 dBm and is rarely usable at all.
I have noticed though, that it sometimes gets really good reception with +HSPA, but then it switches to 3G, and the reception dives to < 100 dBm (most often unusable). It does the same when roaming on the 2G-net - sometimes good reception, but most often really bad.
I have flashed different basebands, but didn't help, so I expect it to be a hardware issue. Does anybody have any idea, what it could be? I can fix most things myself, as long as I know what the issue is and where to get the spare part.
Thanks in advance!

Okay. So I haven't actually been using 4G a lot, but I got around to testing it yesterday. It seems 4G isn't affected by the problem, since it holds a 4G service really well. But as soon as it switches to 3G/+H, the reception drops dramatically.

Same problem here. I have tried many ROMs but the problem isn't solved. Now I am trying to flash .img files one by one and I will tell you how it goes a few days later.
...
Hello again,
After flashing all .img files one by one it still didn't work. The problem was that the previous owner of this phone had the IMEI changed. So I found a guy to recover its original IMEI and now it's all fine.

[Q] Cell reception - What's your experience?

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

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.

Issues with this phone?

I've read reports on the Internet of many users having issues with the Samsung Galaxy S3 such as small cracks appearing in the casing of the phone out of no where. Another thing is the weak signal strength this phone is known for. All the reports I could find were outdated and I really want to like this phone and purchase it.
I'd like to know if anyone knows if these problems have been fixed by Samsung.
Thanks in advance!

Signal has been top notch on mine.....Just as good as my wife's Rezound. Much much better then my GNEX!
Below 40% battery the signal becomes progressively weaker, noticably so, but no issues with calls, mostly manifests itself in data.
Otherwise, though, great signal. As I sit here in the middle of a state park far from anything. I travel a lot, neighborhood of a thousand interstate miles a week, and haven't dropped a call yet.
Device rocks, and haven't noticed any physical deterioration. As a smartphone you can't do any better on the market today in terms of quality, performance or features.
Worth getting the 32 gig model and slapping a 64 gig card in it. Nothing like having nearly 100 gigs of immediately available interactive storage.
4g lte is impressively fast.
one thing to remember is somebody will always have something to gripe about no matter what. that being said the s3 is by far the most solid device i have ever owned!
I've had two different Galaxy S3's on Verizon, and both have horrible data issues. Disconnects from data, and not gaining data back until reboot, slow data speeds when I have it, and signal bars constantly going from 1 to 2 to 3 to 4 to 3 to 2 to 3 to 4 etc....
The second phone has never been rooted or modified, and the first one I tried everything I could think of. So many ROMs, modems, and flashes, and nothing worked. Other Verizon phones nearby work just fine. Just my experience though.

I only got 2 bars where I am at, but looking at my family's other phones, they are about the same in reception (razr droid) . Now my dad who lives out of state, is telling me that when he calls me, it goes straight to voice mail (i dont see any indication that he called) , so this is an issue im trying to figure out, but I have a custom rom and kernal. So hard to say what the issue is for me ( I also got a crack on the screen already from slippage the 2nd day I owned the phone, but its very minimal), happened because I didn't have a case at the time.

The phone otherwise is awesome, Get some good protection for it, it is a must! I carry it in my pocket,but I do feel like if someone bumps up against my thigh that it could break.
I think people are to caught up in the bars. I never look at the bars. If my phone has 4G and I don't drop calls then there is no problems with the radio. I even get 4G in fringe areas where my GNEX did not.
Also, my wife's rezound can say she has 3 bars is a fringe areas but it still takes 10 minutes to
load a webpage.
Bars are a bunch of BS. Usage is what really counts.
Signal strength is what matters. I'm actually considering I might have a bad phone since it constantly loses data or drops to 1x in my apt, where the map shows full 4G coverage and my previous phone (Sprint) never had a single issue. Tested a friends Nexus and it had slow speeds but never lost a connection, and the Nexus is said to have really poor reception.

First question are you rooted? if not you should get an update from Verizon with a new modem. If so go to the modem link and down the newest modem and flash it via Odin. I flashed mine and it seems to help with the single problem I was having. Also when you look at the bars I was told that if your data is on the bars you see is for your data when it is off the bars you see is for your voice.

I am a bit confused by this advice going around. I am rooted, and unlocked. I checked for root access a few times before posting this, and I can still do everything I could before. I have manually received the OTA update, and don't notice a difference in my root capabilities. Are you saying something was supposed to break once I updated?

Poor conectivity

I have been having really bad connectivity recently. I have been having issues sending text messages, having slow data speeds, and really flaky reception. And all of these issues in places where I normally have no issues at all, in fact, I dont think I have ever really had issues like this before. Even when the phone says I have signal it still has issues some times. Being outdoors I dont seem to have issues sending text messages, but I still have poor data speeds. However, as soon as I went inside I had almost no reception to absolutely no reception at all. I know some of this could just be related to AT&T towers but my girlfriend is on AT&T too and hasn't had any issues sending messages, she has a "dumb phone" though if that matters. Other things I noticed as far as signal, it would sometimes have data connections shown, but sometimes it wouldn't show anything and under about phone it would say "mobile network is not connected".
I was on 11/4 CM10 when I started having the issues. Tried flashing a couple new MTD modems, checked APN settings, rebooted, wiped cache, airplane mode toggle, but none of that fixed anything. I did a one-click restore back to GB and wiped everything on my phone, internal SD too, then re-downloaded the 11/4 build and reflashed that. Everything seemed to be better for a while but then I noticed that I was having poor data speeds, issues sending messages, and poor signal again. Now I one-clicked back to stock GB again and didn't change anything and only downloaded a couple of apps that I use often to see if it was CM10 that was the issue, but once again I am finding myself with problems sending messages and very poor data speeds. Also, I notice sometimes that wifi connections seems to get dropped during usage and even though it still is connected it gives me errors.
At this point I'm not really sure what I should start looking into. Is is possible that the internal antenna is flaking out or got fried somehow? Or is it possible that it is on AT&T's side? That option seems most unlikely. I haven't dropped my phone or done anything recently that would seem like it would cause my phone to have these issues. Is there a way to test my phone to see if there is something internally messed up? Should I try getting a new sim? Anything else I can do to try and troubleshoot stuff? Any logs or anything you guys need to give me better ideas?
Thanks in advanced!
Edit: Well, in the process now of doing another full return to stock using GTG's method now. See if that makes any difference by the time I get cm10 installed again.
Edit 2: Decided to call the local AT&T store and apparently there had been a couple reports of connection problems but the lady seem a little surprised by how much I seemed to be effected. We'll see if they get that fixed soon and if that fixes my problems. Still having issues with wifi though...
Any ideas anyone? I'm don't know if the att tower is really sucking that much or if it's my phone. Beginning to think it's my phone more and more. Any suggestions please? I can't get an upgrade for another 2 months and this is getting really annoying not being able to use my phone as a phone..

Bumping this thread cause its happening again.
It did seem to be slightly related to the AT&T towers being down because it went away after a day or so after talking to the local store. However, they said the outage lasted only 3 hours and I had issues for a couple of days.
Anyways, yesterday I started having these exact same issues, called AT&T and they said towers seem fine. Asked them about it maybe being my SIM card and they said that 98% likely it wasn't my SIM card. I might go make them replace my SIM card since we pay them obscene amounts of money each month. As far as the phone, it still has Scotts 11/4 CM10 build with the 11/18 kernel patch. Only thing that really changed in the phone physically was I just purchased a 32gb class 10 memory card. The one thing that makes me think it might be my SIM card is there are darker spots in a couple of spots on the gold plating where it looks like it makes the contacts.
Still looking for advice though.
TLDR; super flaky reception, I go indoors in most places and I loose all connectivity. I normally have completely fine coverage everywhere. No issues up until about 3 weeks ago.
I have had ATT for 10 years and have never had good reception indoors. Only reason I am still with them is Verizon is practically a dead zone were I live.
I ran Scott's CM10 and now Liquidsmooth and didn't notice any increase or decrease in signal strength.

The thing is I've been running cm10 of some variety more or less since it's early life and I haven't had issues. It's just on these certain days for certain reasons I have no connectivity in certain places. Most every other days I have no problem getting an H+ data signal and no problem sending or receiving messages in these exact same spots.
I just don't understand these sudden random losses of connection.
Edit: What do you know. Phone is back to normal functioning today. This is wierd...

[Q] MB865 (Atrix 2) Hardware Question/Help Needed

My MB865 (Atrix 2) started losing signal and restarting. When it does re-acquire a signal, it is always a strong signal (5 bars ~ -65-dB). The problem has been getting worse and it is getting more difficult to acquire/retain a signal. Often the phone will spontaneously re-start as well. The re-starting seems to happen more frequently when I am charging the phone or do not have a signal.
My son has the exact same phone with the exact same configuration, and his is working perfectly. Side-by-side, he will have 5 bars while I'm not able to get a signal at all.
I have been told that this is likely an antenna issue, but I'm truly not sure.
Could a faulty antenna cause the re-starting issue described above? If it is a faulty antenna, is this something I could replace myself? I was unable to turn up anything useful in my search for a replacement antenna for this phone, so I'm not sure where to even get one.
Thanks in advance.
I am having nearly same issue with my atrix 2
I cant make or receive any calls/sms
The signal reception have decreased a lot.
I would like to know what you did to fix the issue

No GSM signal, 3G/LTE works

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 figure it out?

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.
