I work in a midtown Manhattan hi-rise near Rockefeller Center and get full signal bars on any phone in and around the office.
The problem is I get terrible performance. Voice calls are garbled and drop, and sometimes callers go straight to voice mail. E-mail, data and web work sporadically and load slowly if at all. The phone will actually get hot just sitting on the desk as if its CPU or transmitter is locked at 100%, and the battery drains quickly.
It's the same whether it's an iPhone, Android or Symbian smart phone or just simple dumb phone, and other people in my office have the same issues. I even notice the same kinds of things happening out on the street up to maybe a block away, but it seems to be at its worst when I'm in the building. But two blocks away, walking through Times Square or other busy places, everything is OK.
Any idea what could be going on and if there's any way to get around it? This is on AT&T.
Change baseband?
I think it's the fault of AT & T
AT&T is a terrible company
+1 on the AT&T being crap
I tried changing baseband but it didn't help, plus like I said it happens on all different kinds of phones. I've also tried manually switching from 850MHz over to 1900MHz band but that didn't help.
Updating my kernel might have actually helped a bit. It's hard to tell though, because the problem comes and goes.
I'm wondering if the signals are too strong and overloading the phone. Or maybe I'm exactly halfway between two strong towers in this building and they're interfering with each other, is that plausible? This is in the heart of NYC after all, AT&T must have a lot of towers in a very concentrated area around here.
Samsung Captivate i897
Serendipity 6.4
Baseband I9000UGKC1
Speedmod Kernel i897-13E-500MHz
I had a similar problem in my area once, it was rectified by the Network Provider.
Its due the GSM inter cell inheritence. Are you located very near to a Mobile Antenna tower.
It would be worth checking your own office building terrace for same

Heres how you fix the issue. I had a friend with the same issue. 1. open the window of your skyrise 2. take phone are throw it out the window 3. take elevator down to lower level. 4. Find nearest Verizon or Tmobile or sprint store and port your number. 5. take new phone from new network to your skyrise. 6. Congrats your problem has been solved. ANYONE WHO HAS AT&T NEEDS TO GIVE THEM THE FINGER AND MOVE TO ANOTHER CARRIER.
Thanks but if I wanted to hear people say AT&T sucks I would have posted this to Yahoo or something. I get a much better rate with AT&T through my company's FAN account, and I'd rather not pay double to another carrier if this is a technical issue that can be addressed.
For now I can use wifi around the office and put up with the spotty voice coverage, but I was hoping I might find some helpful technical advice here since this is supposed to be a developers forum with presumably mature users.
rathore4u - I'll see if I can find someone at my provider's tech support who understands the GSM inter cell inheritence issue you suggested. Thanks.
In low signal areas, I often have calls that enter a weird mode where roughly every 1 second voice cuts in and out. Anyone else experience this? My Fascinate in the same area never used to have this issue. -1 for the VIA POS. The problem seems to be there on all ROMS including the new EP1W.
When this happens on an important call, I have a growing urge to shatter the phone on the ground. Never had this feeling on previous phones, so once again Samsung has set a new record.
Yep, same thing in for me around 10 miles surrounding where I live. I believe the phone has a ****ty radio, but it is good enough for normal areas, but in an area that has a low signal or a tower with any slight issue, this phone reacts worse than most. My wife's incredible 2 works fine in the same area. When I got this phone, I was hesitant because I heard things about Samsung radios in the past, and low and behold, it was true. Sad because the battery life is great, the screen is great. But between the GPS locking taking forever once in a while, the lag, and most of all the issue you are describing. This thing is getting traded in as soon as the bionic comes back in stock. And if I hate that phone, I will simply switch to the incredible 2. Maybe it doesn't have 4g, but the phone flat out works out of the box and works well.
Just wanted to follow up because this is a real issue where you literally can't communicate with calls in certain areas on certain Charges. I tried two Charges and two sims and the problem still persisted, always in the area in my town only. My wife's Incredible 2 has zero issues. I switched to the Bionic today and the call issues are gone. As happy I was with the screen and battery life of the Charge, I am relieved to say I can now make phone calls wherever I want without concern, and that trumps anything else after all it is a phone first. Just thought people with this issue would like confirmation of other phones that do not have the problem.
I tried to like this phone, I really did. But the frequent voice cut outs and garble leave me feeling angry and thinking who gives a rip about the screen if you cant make a call.
Why did Samsung use this toy VIA chip? Its kindergarden level quality. Its a true POS designed by flunkies.
Have had my One S (black) since a week now.
On few occasions so far, I've noticed intermittent radio drop outs. The phone suddenly looses network (3G/2G) reception for certain amount of time (5-10 minutes). Along with that, GPS reception is also stopped.
This has happened couple of times so far, both times when using GPS-intensive application like GPS Status or Blitzer.de running in the foreground.
Flipping Airplane mode (on/off) will remedy the situation.
Anyone else experiencing something similar? Apart from this issue, the phone is working flawlessly.
Thanks,
G.
Yes i'm having this problem. Getting my phone replaced so hoping its a dodgy phone.
I even did a factory reset incase it was an app i'd installed causing the issue.
Thanks. Let me know if the replacement will work better.
Also, if you have found a way to replicate this, so I can show it at the shop, please let me know.
As for others - can anyone share their experience using apps like GPS status, Google Navigation, etc... and possible drop-outs using them?
Thanks,
g.

Mine doesn't seem to be GPS related so there is still a chance it could be my network playing up and not the phone (although I did ring and ask, and they said all was fine). Im in Manchester new and i'm having issues, back on the Wirral last weekend it was 100% fine. I will monitor the situation.
i hope it is a dodgy phone, Im receiving mine any time now... As a replacement for my Sensation which suffered terrible signal / wifi issues due to the antenna design..
I really hope its not the same on this phone, I will be gutted !

Any news on this I am using Waze as a sat nav and have noticed that I am getting gps drop outs whilst using it ?

Just finished a call with the customer-satisfaction team in HTC Europe.
I left them poor feedback after several email support sessions about this networking issue (signal drop, signal switching 3G/H, WiFi issues + BT + GPS) and they called me to check why.
I repeated the details already spread here in the forum and was advised to do a factory reset.
I mentioned the fact that several users have already tried that with no success so she proposed me to send it back for repair.
She couldn't let me know when an OTA will be sent.
It seems as if they either play "stupid" or really don't know anything.
Hi guys. Feel free to flame me if this is addressed somewhere, I used search and couldn't find anything. My coworker has an LG Vortex. In our shop, we had bad cell service so our boss had a signal repeater put in. Now at&t (all the rest of us are on) works great, full service. This guys LG Vortex on Verizon network shows good service (3-4 bars, I don't have the technical signal strength) and texting and internet work fine, However, for some reason when ever he receives or makes a call it's crackly and usually get dropped. He noticed it to start right after the signal repeater got set up. Any ideas on what to try to fix it, or at least what might be the problem?

This thread can be deleted. Not sure if someone can tell me how or if a mod needs to do so, but it's just taking up space.
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).
Cheers,

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.
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 !!
Is issue still remaining?
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...
