Poor 3G Reception

Treo 750v very Poor 3G reception in buildings and on trains around London.
I have now changed job and work in central London and I have noticed on my route to and from home to central London I loose reception a number of times in various spots but on my TyTN which I took to test had no issues.
I have two Treo 750v and they both are doing it one installed with vodaphone and one Cingular rom. The lady next to me thought I was going mad two mobiles one in each hand and my eyes fixed on the reception bars all the way to London at 6:40am yesterday morning. I have not really noticed any issues with reception before this as around home it works flawlessly and I know it is not related to T-Mobile UK. I missed two calls also and whilst at work, phone on all day I got 3 voicemails. Various reviews on the internet have also said reception is poor on these phones and now it is starting to become a reality the more I use it in different areas.
I tested on the way home I rung my two land lines and spoke to my children and girlfriend on the TyTN and 750v the treo cut out 5 times whilst the TyTN held the connection from start to finish. Testing the 750v set to GSM today the phone cut out 2 so slight improvement I don't know if there will be a fix of some sort i.e. (radio or rom upgrade like the TyTN) over time fingers crossed, There is no difference for reception on the Cingular rom vs. vodaphone. But like anything it could be a hardware problem. I am sure if the treo had an antenna it would be better. First attempt for an antenna less Treo it is a good start. I hope they do a new revision of this Treo or this fault does gets fixed as I love the form factor of this phone far better than the TyTN imo.
Reception set to GSM is far better under band selection, I loose the fast browsing speed abilities of UTMS but call quality is much better overall.
Does anyone else suffer from reception issues related to 3G?
Tmobile
Vodaphone
O2
Sim cards tested in both phones.

I am also experiencing problems on 3G here in the Netherlands. I have some bad reception during calls and also alot of dropped calls when on the move and the phone is trying to fall back from UMTS to GSM.
I am also having some Bluetooth stack problems: the Bluetooth sometimes crashes, even in the middle of a conversation on the carkit. The audio connection gets lost with the parrot carkit.

The issues you are having are just like mine, Not having any bluetooth issues like you mention though. UTMS to GSM is a big problem with the phone it is like it gets confused and then freaks out.
The reception part is really starting to get to me as my main phone it is not doing to well if you know what I mean. I only hope that a software upgrade can fix the issues. I am sure the bluetooth issues will get sorted with an update.

Same here (Italy). Bad 3G reception (Vodafone network): sometimes the 750V switches to GPRS and the call quality is fine, sometimes it doesn't, and it's a pain... I noticed a slight improvement when I upgraded from the original Vodafone ROM to newer Cingular's. Hope this means it's a software-related issue, and can be solved via a ROM upgraded in the future. After all, the 750V is made - like the TyTN - by HTC, so the reception should be more or less the same in both the devices.
Bye,
F.

With my TyTN (radio 1.16) I get reception on a dead spot where I couldn't get reception with several other phone's (Nokia, SE, Motorola). Much better then with the standard radio 1.03 which didn't work there also. The Palm's reception is somewhere in between, and probably software-related too.

I've got the same problem. Fixed it by changing the band selection from "automatic" to "gsm". I'll have to change it back whenever I want to access the internet, which is a pain, but at least it's now usable as a phone.

Cell Interfering With GPS

Here's a puzzler.
I recently started using my automotive GPS again (Garmin Nuvi 1450; same as the 1490) but I've noticed it's acting haywire whenever my Inspire is even close to it. For example, the accuracy becomes off by miles and it thinks the elevation is roughly 3000 feet when the elevation of the area I live is 150 feet above sea level.
Suspecting something, I powered off my Inspire and the Garmin immediately went back to being dead accurate so it has to be something with the Inspire.
I run my phone with WiFi and GPS disabled, I live in a HSUPA enabled area and my phone is set to use all available bands; it's generally in HSUPA mode. The rom I'm using is based off the Cyanogen nightlies, LorDmod kernel, 12.54.60.25U_26.09.04.11_M2 radio.
If anyone's experienced something similar or has any potential fixes that would be great. Putting my phone on airplane mode every time I get in my car isn't a very viable solution.

Have you tried Garmin Customer Support? It sounds like the problem is possibly with the Garmin, and not the Inspire. A stand alone GPS unit should be able to withstand interference form a cell phone, IMO...

It doesn't happen when my brother's Thunderbolt or my old iPhone 4 is around it so I'm kind of confused. I haven't called up Garmin yet, just noticed it going haywire today, but I'll give that a shot.

Yeah weird problem if only confined to the Inspire device. I have noticed for YEARS on AT&T with multiple handsets (including the iPhone) that something with the native signal interferes with the landline phones and some computers with stand alone speakers in the form of static and beeps that make it sound like I am trying to contact the Mother Ship...only at my employers cubes though...

GPS frequencies are at approximately 1227 and 1575 MHz. The Inspire cell phone radio transmits in the 850, 900, 1800 or 1900 MHz bands depending on whether it's using EDGE, 3G, etc. So in theory it shouldn't interfere, unless some weird harmonic frequency situation is going on. You didn't say if you're using bluetooth, but these frequencies are in the 2400+ range (close to the WiFi range), so once again there should be no interference. It may be worth turning it off just to see (if you haven't tried this already).
Since the other 2 phones you mentioned don't cause the same problem, this does potentially point to your Inspire as the source. Maybe for some unknown reason your Inspire is poorly shielded (possibly due to some sort of defect during assembly) and is therefore spitting out more interference than it should. Or your radio is not running within spec due to some sort of hardware or software issue, and is spitting out spurious interference.
Personally I would try flashing the stock radio version 26.06.06.30. This is the stock radio that is FCC approved to run on the Inspire, and therefore has passed the FCC testing and certification for spurious signals, interference, etc. Get the version that comes with the RCData file, in the radio thread in the dev section.
One more thing to check: make sure the cell antenna (built into the inside cover of the SIM/SD cover at the bottom of the phone) is making good contact with the phone when the cover is on the phone. Look for the little gold contacts, and make sure they are clean and sticking up slightly with a "springy" tension to them, so as to make good contact. The reason I say to check this, is because if your antenna isn't connected 100% properly, the cell radio may increase its transmission power to compensate, which might also increase the interference it creates. This is pure conjecture.

What about Bluetooth?
Took too long. Just listen to Henry. He's a friggin genius. I think. He always seem to help me.

Yar, that's the GSM signal interfering with electronics (usually cheap speakers) that aren't properly magnetically shielded against the GSM frequencies AT&T uses.
EDIT:
@biglittlegato - Good question, I always leave bluetooth disabled as well; I never use it. So much so I forgot this phone supported it. Heh.
@henrybravo - Cheers. I'll reflash back to 26.06.06.30 with the RID and see what happens.
EDIT2:
Also fired off an email to Garmin as well. Their response time window is 3 days so we'll see what they say as well.
The odd thing is that it was working fine when I drove to work this morning. Maybe it has something to do with the network load. Bleh, I'm just throwing stuff out there at this point.

That all makes sense . Rather annoying when on the land line phone with someone at work though, or worse, we have an overhead paging system, and the beeps and static kick in when I'm on the overhead...just blame my employer's choice of inexpensive hardware and not fault my phones or cell service though .

Haha I know EXACTLY what static/beeping sound you're talking about. My old Motorola prehistoric flip phone and maybe even my razr used to produce that sound whenever I was sitting at my computer, just before the incoming call would ring my phone. Annoying as hell.
Hasn't done it on my newer phones...Captivate and inspire.

Yes the good ol' RAZR... when I had this old alarm clock that is never really off...would start the Home World transmissions 5 seconds before the phone would ring with an incoming call...I be drunk n think it was magic...well not really but sort of....

Cheers for your guys' help in this matter. There were a few updates for the nuvi that Garmin sent me and I flashed the 26.06.06.30 radio and the issue seems to have dissipated. Still not sure what exactly fixed it or if it was just a GPS reading fluke but all is well now.

[Q] Simcard issue?

Hey guys,
i have a strange possibly simcard defect issue (tried the simcard in several mobil phones):
I could hear the person i called very clear and fine ... but he hears me like a robot.
The signal strength is fine, so i doubt thats the issue.
What could this be related if not due to the signal strength? ... (i am on a village so no GSM/WCDA problem since only GSM is availlable).
Thx for help
Greets
Tomatoe

As far as I know, it is not related to simcard and the signal strength - if it was about the signal, you would not be able to hear each other well or the voice would be skippy.
What I could think of is if the microphone is not working properly, or the receiving end is having issues with his/her speaker. Could also be something to do with codecs or something similar - I haven't researched those areas enough to tell for sure.

I would say its the micro phone, did you get it wet maybe?.

[Q] Call Quality Issue

Hi All,
I wonder if someone can help me. I am having an issue with call quality with a number of users on O2 (UK) and can't seem to resolve it.
In a specific area (about 20 meters radius) all incoming and outgoing calls have very poor outgoing call quality, the person on the other end of the line describes the experience as "being underwater" or "robot voice" and if it's particularly bad every other word is cut out. My users can hear the other person perfectly with no distortion.
This issue is happening on a number of different handsets, SIM's and phone numbers.
I have complained to O2 who have provided a femtocell "Boostbox" which doesn't seem to have helped at all. All my users have always had 4 bar full signal strength, with or without the boostbox.
If my users walk out onto the car park the signal clears up and all is well (although this is no good for business!).
I've come to the conclusion that it must be something interfering with cell phone quality as this issue only started a few months ago.
My question is do my symptoms sound like interference or something else (an overburdened cell tower?), and if it is interference, how can I track down whats causing it and save my users a lot of headaches.
Thanks for any help

T-Mobile 1+ 7 Pro call quality issues

Am I the only one out there experiencing severe call quality issues? My phone (T-Mobile OnePlus 7 Pro) is suffering from severe call quality issues.
I seem to be having the issue with the following configurations in an attempt to narrow down / in on the issue:
Galaxy Buds (BT Headset) = Calls on Wifi Calling, Regular LTE and WhatsApp calls. Broken audio (stuttering)
Direct Phone microphone (on handset) = Calls on Wifi Calling, Regular LTE and WhatsApp calls. Broken audio (stuttering) / Drop-outs
Purchased USB-C to 3.5 mm adapter to wired headset = Severe Echo on Wifi Calling, Regular LTE and WhatsApp.
I've tried driving into range of another tower and experience these same problems. I picked up my daughter's iphone X and on the same towers and wifi network, these problems don't exist. The call quality is pristine.
On my Note 8/9 (can't remember what the current one is, but I own it), the problems don't exist in these same configurations. The problem is clearly local to the OnePlus 7 Pro. I've done the "clear cache, reset networking, reset wifi" solutions and they don't seem to help. At this point, I'm wondering if it's a bad phone or just bad software.
I'm at my wit's end and pretty much feeling buyer's regret right now, because I so wanted to love this phone, but it's caused me more heartache than ever. Obviously, the phone is up to date on the most recent version of T-Mobile firmware, but I can't possibly imagine a phone could be so bad at doing what a phone does and pass the certification lab for the carrier and get the amazing reviews that exist on the web.
I'm a few minutes away from just going back out to the store and buying a new Galaxy S(whatever is the most recent)+
**frustrated** and **confused**
Lol..

Incredible cell reception and call quality here, on international stock, the weird part for me is it sounds worse on VoLTE and Wifi calling. Regular voice calls are outstanding.
But if you have both of those disabled and the call quality is that bad, I would exchange/return it.

Call quality is excellent for me as is reception. TMO on TMO Rom. My only issue is DUO freezes the person on the other end for me. Its only been to the same person so far but that is my only issue

You have done soft reset, but try to do a hard reset(erase everything instead of clearing cache). That helped with some crackling noise but.

Call quality not even in the same ball park as my tmobile note 9.

I also had issues with my OP 7 pro. Specifically on speakerphone wife could not hear me at all. I was on the international variant + T-Mobile. I ended up sending it back. Bought the OP 7 and have the exact same issues. I sold me OP 6T tp upgrade to the 7 series. I ended up finding a used OP6T in offerup. Popped the SIM card in. No call quality issues and people can hear me just fine when in speaker phone and driving. I usually have my phone placed in the center console in my car. So for me this is the primary way to talk. It sad that the OP 7 series has these issues. I was really hoping they would fix this in a software update. Still handing on to the OP 7 praying for a fix. But I may just end up selling it on swappa.

Have you guys tried to get a replacement? I don't have any problem with call quality. I use Bluetooth headset or reg phone on ear way most of the time, and rarely on speaker.

I had that problem on the T-Mobile variant and when I converted it to the international firmware it doesn't have that problem now

My call quality is really good sometimes. Some times, it'll have weird moments where I get muted or the other person does. Speaker phone mic sucks real bad though. I hate using speaker phone if I need both hands to do something, so I ordered a bluetooth headset.

I primarily use the speakerphone for calls so this is kind of a show stopper for me. Desperately looking for a fix. Might have to sell mine on swappa.

That's probably why you aren't experiencing the issues we are seeing. Its mainly on the speakerphone. I am currently using a op 6t until I can find a fix. I don't have any issues on the 6t.
