[Q] Bad Reception on TMOUS Tab - Galaxy Tab General

I have Roto's JMG on my tab, getting a very weak/emergency call only in my room where I used to have at least 2 bars.
Is it normal?
I just cancelled my data plan for now, all i need is a decent voice signal on my Tab.

Dropped Calls on X1a... No WDCMA to GSM handoff?

Hi everyone,
I'm on a fringe coverage area with AT&T. I have a pretty new sim card, but I noticed that I get a lot of dropped calls while on 3G (or H). I usually get 1-2 bars on 3G. Shouldn't the call I'm on, hand-off to Edge if the signal is not strong enough on 3G? Right now, its dropping the call altogether on 3G with no fallback to Edge. Is the Xperia's radio to blame for this?
Thanks!
i dont know who is to blame but if your on the fringe as you say, you should just manually set your device to use edge/gsm.
it will save on your battery and have less dropped calls. otherwise, you phone will keep bouncing between signals.
i also have the same problem and i am curious of the answer i dont want to lose 3g all together but i have 1 bar in my house and drop calls also.
Has anyone on AT&T tried to flash their xperia with the Raphael radio? Is the signal alot better?
not just exactly the same problem here, but similar (according to the network). at home, i have no 3g coverage and manage to get edge at best, problem is intermitantly my voice stops, even though i can here the other caller perfectly, the phone still keeps between 2-3 bars of signal, and i can even stay on the call over 30 seconds after it happens. the other caller can just hear like a dead noise. the network has me testing the 3g thing for the next couple of days though.
PS. this also happened with a K850i and a K800i

O2 HD2 upgraded 1.43 to 1.73 now V.Poor signals

At last UK O2 network pulled their collective act together and got a much needed updated ROM out for UK O2 HD2 customers. I installed it two days ago after getting it from the HTC website.
I can now say categorically that this new ROM has resulted in me receiving a significantly worse data & phone service. For the past 6 months I got an HSDPA signal whilst at home only on occasions would this drop to slower 3G strength and never to GPRS. Voice calls were pretty reliable whatever the data signal was doing.
Now I've had several missed calls - some gone through to voice mail even though the phone's showing full GPRS voice signal and my data signal has dropped off the planet - I can only get a GPRS signals now most of the time with occasional blips of 3G and HSDPA! I feel like i've gone back in time!
Has anyone else experience any O2 HD2 official ROM upgrade data signal issues? I want to re-flash back to the old 1.43 at this rate - I haven't noticed any significant differences between the two, they didn't even bother to fix the SMS bugs!
I think there's something wrong with o2 network in last few days (a week perhaps?).
I haven't changed my rom recently, but I got weird loss of services (voice and data) while the signal was pretty good. I wouldn't even realise this, but when I've tried to make a call last week (thursday or friday) I was not connected. my friend who was standing next to me dialed my number and was diverted to voicemail. wth? switching band to gsm have helped, but I had the same issue today- good signal, no voice (both ways) and data. hspa, Bedfordshire area if it's any help....
I had poor reception from o2 over the weekend... 3g was awful
Iam sim free with o2 sim back to stock rom 1.43WWE

That's interesting. I'm near Kingston, SW London - I stuck it on GSM only half an hour ago and received calls again no problem. Weird. When I put it back on Auto the phone can't hold on to an HSDPA signal for any length of time before bouncing around to 3G back to HSDPA then back to 3G then eventually on to 2G...where it stays.
Something's gone a bit wacky
My HD2 is one of the original ROM locked HD2's from O2, however I use it with T-mobile.
After installing the latest ROM from O2, no problems with signal.
It would seem its an O2 tower problem, not ROM related.

Bad Reception: T-Mobile or HD2?

I'm in an area that t-mobile maps show should have excellent phone and data coverage. Both are horrible. Data service is almost always edge with very few bars. If I ever do get 3G its usually only momentary and never above one bar.
The problem is reception doesn't seem to improve regardless of where I am. I drove to a neighboring state along freeway that t-mobile showed had full coverage. But the few times I did get a signal, I was roaming.
So, I arrive in Boulder CO thinking I should have excellent coverage, but nothing changes. Hardly any signal strength when I do have a signal. I've tried all the radios, several ROMs... even the stock one. Nothing helps.
The question is:
Does t-mobile coverage general suck? This is my first time with the company. I plan to get someone's version of the Galaxy S, but if t-mobile coverage is this bad, I'm not getting theirs.
Does the Leo radio generally suck?
Do I have a bad phone?
Is there an app that measures and logs signal strength (preferably with GPS)? I've seen them for wifi, but is there one that tracks and logs the voice/data signal on the t-mobile network?
I had a G1 before the HD2 and I usually get the same or one bar less than what I used to get with my G1 in the same places.
Try these

1: its the reception but they have REALLY good reception around the US are you surround by tress or alot of buildings/businesses?
2: i prefer the 2.10 radio it works really well
3: call t-mobile and tell them bout your problem, but before you call do a hard reset and dont install any apps, if that doesn't work Switch your sim to another phone and see what type of service you get but use a touch screen phone
i have a different problem BUT VERY ODD!
At my house i get 3g but i can't even receive calls or call out but i can text perfectly and use the internet, i switched my sim to another phone and had the same problem i get 3g but wen people call me it goes straight to Voicemail, i found 2.10 works the best for me but i live in VEGAS it still didnt fix it but it kinda made it better...

Home office in an average neighborhood. I tried to find an app that measures the GSM signal strength. I found a demo of MobileGX P3Kit and it did just what I wanted except it doesn't log the signal strength. But, I guess the company went out of business. It only worked once, and the website link is dead.
Does the data connection use a different frequency than the phone signal connection? That's about the only thing I can think of that would cause the problems you have at home. Weird stuff.
I am in a marginal coverage area and the HD2 radio is horrible. I'll go from 3 bars to no bars back to 2 bars then to none in under a minute without moving my phone.
On my Blackberry I would get usable coverage everywere in my house, none in the basement, with the HD2 its pure luck if I can use it on the front porch.
When I'm standing below a T-Mo tower I will often drop a bar of signal... and thats standing under a tower, several other people with HD2's that I have spoken with have the same experience.
Seems like it varies from phone to phone, and from location to location.
I had a Cliq and despite it being a POS, it had excellent coverage, then I got a Nexus One and its coverage would drop regularly at home. It would drop so often that I didnt really use pandora or surf the internet unless I was on WiFi.
Now I have the HD2 and its been somewhere in the middle. Lots of people say changing the radio will fix your issue. I would definitely start there. Just because a radio version works for some doesnt mean it will definitely be the best option for your location.

Strange, I just left Boulder and I had full 3g signal strength.

Reception issue

I've placed my Omnia 7 next to my girlfriend's Focus in a place in my house that has traditionally been very poor in reception. She is able to get 1-2 bars on 3G compared to my NO SERVICE-zero bars on EDGE under the same network (ATT). Is anyone else getting fairly weak reception on their Omnia and is it all possible that my 4 year old SIM card is accounting for the difference in signal strength?
Next chance I get, I'll try swapping our SIMs....
I am not too sure of this but maybe the Omnia 7 isn't using its full potential on the US carrier since it is a EU device. (this shouldn't matter really but I am trying to say that it might be a software issue of how the phone switches connections)
By that I mean that some forum members (check the Focus Forum) have fiddled with the diagnostic codes to make their Focus phones have a more stable 3g or above connection.
Trying looking into that and posting there since the Omnia community is a little bit smaller it seems.
Or the phone is just not up to scratch ;D

It could be your SIM if its old and not a 3G sim. Do you get 3G elsewhere?
The reason i ask is that EDGE is a 2G tech.
I work in mobile tech support myself, and i have seen SIM cards cause some seemingly random issues. (1 in particular was a handset unable to read SIM contacts, but his prior phone was OK)
On the other hand, i have also noticed 1 bar less then was displayed by my prior HD2. I have dismissed this as you should not reply on the number or bars to determine signal strength. They are coded differently. There is no standard, and in fact, changes by the Carrier can effect 'bars' displayed on the phone. (Think of a little buzz box with a 20ltr tank reporting 1/2 full, while a 4x4 with a 40ltr tank reporting 1/4. Both have the same amount of fuel)
ive noticed i get a bar or two less than my girlfriends desire and my diamond2 all on the same network & with new sim cards. this generaly means when she has 3G or HSDPA im stuck with GPRS unless were in an area with 3 or 4 bars.
Not entirely sure, but I think the Omnia 7 doesn't support US 3G frequency bands, that's why it's limited to EDGE - and then it depends on where you live... I suppose it's entirely plausible AT&T has a strong 3G network in your area, but not an EDGE one
mine has a good reception ... as good as other devices ...
In my House I sometimes got 4 dots but when a call comes through the connection is lost between talk without walkin on the same spot.. First I thought ok bad reception (had not before with my xperia1) But yesterdaynight I got the same problem outside my home. So the conversation gets totally jammed.
And I live in the Netherlands and not in the county side but in the big city...
So I managed to switch the SIMs on my girlfriend's Focus and my Omnia and unfortunately the poor signal remained on the phone, ruling out the SIM card having any negative effect.
I will get 3G outside my home and sometimes 3G+ (I'm not sure what the difference is), but inside my house, side-by-side, the Focus gets better reception and is more often on 3G whereas my Omnia will get worse reception often on EDGE.
Lame!
I might have to drop some cash for ATT's Microcell... Damn you ATT.
I notice it as well.
When I used my HD, the reception was fine inside MRT tunnels. Now with my Omnia 7 (same SIM card, by the way), I can't get a clear signal inside MRT tunnels during my commute.
Shame.
I don't know what caused it, though.. Anyone can shed a light on the issue ?
Mine has just suddenly started to not have any signal ANYWHERE in the house... the other 2 Vodafone phones here have near-full signal.

Hi I think I have found you a solution. Having been on the Focus forums I have noticed that people have enabled full "3g" through the root menu in diagnosis software.
http://forum.xda-developers.com/showthread.php?t=839154&page=8 ..... read this first please. Looks like it enabled full 3g but messed up his GPS settings (could be that he configured it wrong) Always make sure that you write down your original settings when using Diagnosis tool!!!!!!
If this doesn't help you then maybe flashing a different rom onto it would work.
I played around with some of the diagnostic settings but nothing really changed.
How exactly do I access the root menu to change the 3G settings you mention?
*#197328640# - Root Menu
Things you can do with this code
Speed up your internet by enabling hspda/hsupa
*#197328640#
1,8,3,5,2,3,[END]
Just be careful with this stuff. And always remember to back up your previous settings by writing them down somewhere so that you can restore it.
The link I gave you above leads to these codes.
BTW .. samsung updated the diagnosis tool .. if you have 0.9 something you might be fine! But if it updated then you will not be able to get into the root menu.

[Q] 3G @ no bars not switching to edge

Hey folks, I noticed that on my At&t samsung focus that the connection often doesn't switch down to edge when 3G is at no bars(tested-no data). And I know that areas I visit often have edge coverage because i can turn off 3G manually and get good reception... but any insights/solutions as to why the focus doesn't automatically switch bands/connections? radio bug?
edit: I did do the hsupa/dpa release hack via diagnosis console.
This also bugged me. In my experience this is not limited to the Focus. I encountered the same issue with the Tilt 2. It took probably a complete loss of 3G signal for the phone to switch to Edge and then even though the Edge signal had 2 bars, as soon as it got just a trace of 3G signal it went right back. Fortunately with the Tilt 2 I am able to turn off 3G and the phone stays in Edge all day long in areas where 3G os crappy. I wasn't able to do that with the Focus.

I'm having these problems as well and I also did the hack. Since then I keep getting cannot connect messages in IE. It was so frustrating that I undid the hack(?) and this happens all the time. Can someone give me the settings to make sure I restored the original settings.
