Random Reception problems

My Trinity has decided it's had enough of working and is doing some crazy stuff. Firstly if you have the phone in Automatic registration it never gets signal but will say G or 3G etc. At this point I cannot make or receive calls or texts. The only way I have managed to get it to work is by turning Auto to Manual and selecting the network..yet sometimes this doesnt work, it will show reception but calls and texts still dont work, Data works tho!!
The only way I can get a working phone is selecting GSM from the network type instead of Auto. Obviously it sounds like a 3G/UMTS problem with the phone, Sim works fine in other phones. Have tried reflashing ROM and Radio.
ANy Ideas

are you sure you have good 3G coverage in your area?
I would phone your operator.
I had a similar problem on Vodafone only when set to auto. The phone tries to pick up the 3G weak signal and so it's always droppin off and on.
The guy at Voda suggested that my phone was paired to a 3G base station several KM away, when it could have used the GSM station a few 100 metres away.
A plus of using GSM is battery life lasts much longer!
Of course there could be a hardware fault which would be unfortunate.

Additional suggestions:

I assume that you've configured your phone to your operator and that you've tried different radio ROMS to ensure optimal "fit" between your specific PDA and network operator. If you haven't and none of sickboy555's suggestions work, maybe you should check these two alternatives out as well?
Cheers!

Well the problem initially started at random, did actually do anything, also I have tried about 4 different ROMS now and all have the same problem. I'm on
In terms of reception I have full 3G signal (4 bars according to the screen) as I am just outside the centre of the city yet nothing comes through but data. tis V strange. I may retry 3G when I'm somewhere else just in case its down to the local Cell.
I've decided to bite the bullet and just disabled 3G most of the time, if I need faster data I'll turn it on for that until I can upgrade to the TyTN 2. mmmmmm

Phone loses reception, restart to get it back?

Love love love my Desire. Few little problems here and there (Music Genre, Battery life etc) but the one main thing that is really bugging me is, that if I lose reception (I live in a area with lots of valleys), it will never regain reception even if I enter a town centre or City. I always have to either switch Airplane mode on then off. Or more often than not, turn the phone off completely and switch it back on, where it then finds reception straight away.
Anyone else getting this?
I'm on Vodafone and using the latest Generic Rom

I'm not sure if this is the same problem, sometimes i
have no data connection (i guess 3x since i have the phone).
I see some bars but no Edge or H (3g) sign and obviously i have not data connection ... dunno if the phone part work, will try next time.
anyway, i could get the data connection back by switching from 3g to GPRS mode and later back. You can see in the bar that for a very short time all GSM connection is gone ... i guess it's similar to switching to airplane mode ...
Maybe it's worth a try for you, maybe it's totally useless
btw: i'm living in a city, the nearest celltower is just a few meters away.

I have similar issues but I had the same issues with my ADP, not just the Desire.
Inside my University buildings I lose reception very often and the GSM connection always reestablishes itself but not the Data connection. When I reboot my phone the same thing happens. There is a good chance that the Data connection wont initialize and I have to switch to Airplane mode and back to get the Data connection. Really frustrating sometimes :/
Another very, very annoying problem I have is that sometimes it shows a data connection but it can't be used. It shows E/3G/H but whenever I start an app which uses data, it always times out.
Another problem, which is probably not fixable, is that my Phone likes to jump between E/3G/H quite a lot and every time it does do so, it seems like the app using the data connection has to reestablish the connection. This led to quite some timeouts when it was constantly jumping around.

I get poor 3G reception on my desire ( orange UK ) , have to go outside in the rain to get a better reception

vodafone have been getting worse and worse of late, I travel from surrey to london (central) every morning and was getting the same thing. I was even getting this all the time with a blackberry 9700, It is not the phone as I tried tmobile sim card in the same areas and didn't have the problem. Only 8 months to go of my contract which I will not be renewing.

I have an issue where if I use wifI at home for an evening, when I switch wifi off, the 3g data connection does not re connect. If I re boot, it connects immediately.

Assuming Vodafone uses Sim cards. I just had the same issue, here in the states with AT&T. I thought my Tilt was at fault so I borrowed a little Samsung flip phone and put my Sim in it but it did the same thing.
I had AT&T replace my Sim card and so far, 48+ hours, it hasn't happened again on my Tilt.
Might be worth a try.

I have this same problem at home (in South London) with my desire and had it with my G1 too (both on T-Mobile). I'm pretty sure it's a network issue rather than android or the phone. I constantly have 3 bars of H signal and during the daytime it's blazing fast but after around 5pm and all day at the weekends it becomes basically unusable with network timeouts more often than usable connections. I work 40 miles away down south and I get a consistently fast data connection down there with none of the time out problems.
I also tried using a t-mobile sim in a 3g dongle and had the same issues, it was great during the day and incredibly slow with loads of timeouts in the eve. It reminds me of when unmetered ISPs first came out and couldn't cope with the amount of bandwidth being used, I'm pretty sure this is a similar capacity problem in some areas.
I've been in touch with t-mobile and they are escalating it to 3rd line support so will wait and see what happens. As it's at home I can use wifi and it's not the end of the world but it some respects I wish I hadn't upgraded and switched networks instead, my gf's on O2 with the phone that is not to be named and doesn't have this problem at all.

In response to your most recent query on a different thread you had posted (now closed):
Will changing the radio help me?
Currently got this issue happening daily
http://forum.xda-developers.com/showthread.php?t=676866
If I lose reception at any point, I have to either turn Airplane Mode on and off or restart the phone to get ANY sort of reception.
Currently on 1.15.405.4 Generic Rom with Baseband version 32.30.00.28U_4.05.00.11

Yes, by updating the Radio version this can improve things like battery life, network reception, Wi-Fi, and GPS signal strength, but this also depends on your region - it will either work better for you or could be worse. It may be worthwhile changing to Radio 4.06.00.02 for a few days and try to establish whether or not it improves your situation. If it doesn't, then just revert back to the stock Radio version.

I had a very similar problem on my Touch Diamond 2. It turned out to be a faulty aerial and had to go back to HTC for repair. Worked ok for a while after that, then it started again. An update to their latest ROM then solved it. So a hardware issue and a seperate software issue both produced the same fault for me.

Loss of signal, no auto reconnect.

I am having an issue on my One X (unbranded and unlocked) with the signal vanishing and not reconnecting unless I force it. I was wondering whether it effects all networks or just networks that use more than one carrier. Three has its own 3G network but it uses Orange 2G signal. I also saw a thread with the same issue on T-Mobile / Orange which is also dual carrier.
I am wondering whether it is the switch between these networks which is causing it to lose signal and not reconnect.
I have had several instances where my signal has an R next to it as if it is roaming, this would be when it is connected to the Orange 2G network, I never had this problem on my Desire HD or Sensation.
Does anyone know of any issues on Vodafone or O2 regarding signal loss or is it just networks which use multiple carriers.
My One X is stock and bootloader has not been unlocked.
Thoughts?

Are you still on the 126 SW?
As your unbranded then you should be able to get the 128 update.
With 126, my Three handset recieve level was about -88 to 91dbm.
With 128 its now at -75dbm in the same location.
Most, if not all of the roam to Orange has now been disabled, remaining where there is no Three signal at all.
Steve

No I have upgraded to 1.28, unfortunately I am still in an area where it does switch to Orange 2G signal.
It seems to hang on to 3G until I have virtually no signal, then goes to no signal and doesn't reconnect unless I force it. It seems to mostly happen when I put the phone away on my pocket so I dont notice I have no signal until I check my phone.
I lost signal today and to test the reconnect I left the screen on and I drove about 20 miles through large-ish towns and it didn't reconnect once, had to force it when I got home.
Not sure if this effects single carrier networks, O2 or Vodafone?
Sent from my HTC One X using Tapatalk 2

Have you had the same issue with any other handset?
Are you a new customer to Three and this is the first you have seen of this?
Reason I ask is when I was thinking of going to Three for my main phone, I tested with a handset I just used for tethering off the one plan.
I drove out of town to an area where I guessed there would be no Three coverage.
The signal hung on for ages but when it dropped I made a note of where it dropped. After a few moments the handset went over to Orange 2g. I then drove back home. I must of drove at least 5 miles past the point I noted earlier before the Orange signal itself dropped and had to force the handset to Three myself.
This sounds similar to your issue and was with a Desire S….but you say you didnt have this with previous handsets. All very strange
Steve

I've had a Desire HD and a Sensation both on Three and never had issue on either of these.
There must be something different about the way the One X handles the switch of signal, or maybe it's just faulty.
Might try some other SIM's from other networks, if that doesn't work I'll get a replacement.

I'm on three and it never seems to switch to gsm just looses signal all together and takes ages to reconnect once I move location. this is a proper pain I've had the phone replaced three times changed sim still not got better I'm thinking its the radio version on this phone or some software related issue.

If you're phone is from Three you won't get the update until Three release it.
I did see on another thread that Three won't be releasing 1.28 as HTC are currently working on the next update. Don't know how true that is.
My phone is unbranded and unlocked to any network, which is why I got the update.
Think I'm going to get a replacement and see if that's any better, hope it's not a general issue with the one X having lower signal.

If you dial *#*#4636#*#* on your phone and select phone info you can select GSM only which is 2G, this really improves signal but because it's 2G you are stuck on really slow data speeds.
If that is the case and you've had 3 replacements, maybe it's worth holding out for the next update to see if that fixes the problem.
I'm a little uneasy about returning it for a replacement as I don't have any other problems with it (bad screen seal, banding on display or yellow display) I may end up with more problems with a replacement.

Is any chance change three rom on factory rom?

I had similar issues to what you are describing with yours on my original unlocked/unbranded HOX on T-Mobile. I had issues on top of the ones you mentioned where it was also saying I had a signal and had appeared to lock up and would just drop the mobile network and say at the bottomg of the screen "preparing sim".
Most the time I was stuck with putting it in and out of airplane mode to make calls, only for them to drop or fail all together.
This was on both 1.26 and 1.28 FW. In the end I took mine back and swapped it and the replacement has been perfect since. so it was without doubt a hardware fault in my case!
Good luck solving your problem, but I would suggest taking it back and getting a straight swap.

You can't change you ROM unless you unlock the Bootloader at HTCDev and this will void your warranty with HTC.
Three will release an update eventually, and 1.28 is no better signal wise for me than 1.26 was!!

Interesting, I too had the Preparing Sim message until I got a new SIM from Three, this seemed to fix this message but I am still having Signal Problems.
I think I'll follow your lead and go for a replacement, I have to use Airplane mode to force the signal to reconnect as well.
Thanks

I can confirm I have these problems. I'm on three but the phone was from Dialaphone and with orange but is unlocked. I have exactly the same problems as those been described. This is a very irritating problem that makes me miss calls and texts in my poor 3 signal area.

I think you're best off to return it for a replacement, that's what i'm going to do. Hopefully that will fix my problem and not create any more!!

I have the same issue on my device. On my 2nd replacement and its still the same.
No problems with my iPhone 4S.
Hopefully a radio update will sort this out.

I think it might depend on location, in some areas the 2G signal (Three use Orange network for 2G) has been turned off. In my Area (South West England) I still have access to the 2G GSM Signal.
Obviously Three save a lot of money from turning off GSM and not paying Orange to use their network.

Strange Antenna Issue

Today my phone started having some issues.
In places I was supposed to get full coverage and all bars I am know getting only 2 bars...
And in places I was getting 2 bars I get no signal at all !!!
I think it is an Antenna thing. Maybe it is broken, IDK...
What could I do? I have no warranty as I bought this phone 2 months ago in EUA and I live in Brazil...
Thankss

Anyone?? Help??
I've opened my phone and Everything seemed to be clear and OK.
One thing. When I get signal and start using the 3G a lot. The Signal DOES NOT go off.
This is very strange...

It seems to be an Power Amplifier issue. I am gonna put in a Repair Store and they are going to try to fix my phone.
I am going to keep updating this too with the progress.

What were the dbm stats? Your signal bar never tells the truth unless there is no service at all.

the signal bars are responing to dbm status.
I am checking both on the same time and I didnt get any anomalies betweent them...
I just put the phone to work in a place near home and they said it was an Power Amplifier issue and they're going to try fixing it.
Thanks.

I have exactly the same problem but my phone has only dealer warranty. Is there any chance to fix this through software?

If you have this exact same issue you cant fix it through software, because its an hardware problem...
It should be an hardware thing, if it isn't I don't know what else I could do.

Just updating...
My phone is now working. They changed the PA ( power amplifier) and now I have normal signal!
BUT, I am having two issues.
When I select "only use 2g networks" the phone than changes to edge and connects. When I deselect the 2g option the phone reconnects but it keeps on 2g. It does not switch to 3g...
I have to reboot the phone/radio.
AND,I am not getting 4G HSPA+ anywhere! Only HSDPA...
ANYONE????

Today I also have noticed problems with connection. I've very fresh GNx, had it with me at the office since Monday but today whole day was on GPRS. I thought it is an issue from the GSM network but after coming home where 3G should fly (and it does on Motorola Defy) my GNx was still on GPRS.
But when I make a call the data connection returns to 3G and some time after switches back to 2G.
If I leave phone somewhere where is better coverage it keeps 3G.
Meanwhile my Defy has 3G everywhere.
Shall I sent the GNx back to Amazon?

Man,
If you are in warranty you should return your phone for them to fix/change...
Try changing radios before doing that. It can be software related!

I'm on the same radio since beginning. And the same ROM was while phone kept 3G and now, when it is loosing it.
However, I wonder how much the network could influence the situation.
I've left overnight Nexus and Defy on the strongest coverage point and in the morning GNx was still at GPRS while Motorola switched from 3G down to GPRS.
I'm getting paranoid (and not talking about ROM). Restored phone clean via fastboot to factory state. Will be watching it over weekend and then decide what to do.
8 hrs later.
Phone kept weird for few hours at work and now flies with full range 3G. Also at home where yesterday it was switching to 2G.
I bet this was Vodafone way to thank me for cancelling my contract.
Gonna keep it at pure stock for an hour or two and then will change to some custom ROM... Maybe.

Updating again.
I've been testing my phone with the new "Power Amplifier" and now I can use my phone regularly.
The problem is... The phone does not support anymore the frequency of 850Mhz neither 3G or 2G.
I THINK they have put a PA that does not amplify this frequency.
My carrier uses: 2G:900/1800 3G:850/2100 3.5G(HSPA+):850Mhz mostly
So I understood why in some places I dont have any 3G coverage and in almost all places I can't get HSPA+ speeds.
Am I correct? Does the PA has to do w/ all this frequency thing?

[Q] LG G3 Three UK Signal Dropping

Hi all,
Is anyone else experiencing terrible signal on Three UK? My dad just got his G3 and compared to his Nokia 925 signal on Three is atrocious, and seems to drop in an out constantly?
Anyone else experiencing the same?

Not on 3 but I'm on ee (T-Mobile) and I have some prob outs at times that I found has been bit strange but most the time I have great signal.

I am on Three, had no signal concerns at all except in areas of weak signal. The phone doesn't seem great at maintaining a connection when signal is weak, whereas other phones might stay with 1 bar this drops to none, but otherwise signal is as good as can be expected.

No problems here

I have had this problem on 3 UK. I found that going into network settings and choosing the network mode without LTE stopped it from happening! Any idea why this may be anyone? Do we have defective units?
Matt

The g3 is just very slow at finding signal when its lost signal - what is happening is you are losing signal (even if just a split second), any other phone would probably instantly reconnect but the G3 seems slow - this is all software based (well, radio firmware) and can be fixed (and word on the street is that it will be fixed in the next, August, release).

Thanks for the info, I won't be sending this off any time soon then! Also thanks for your unroot and chromecast volume fix guides they have been very helpful.

Wouldn't enabling fast dormancy help to find the signal quicker if it loses it?

I have also seem a connection problem on three in the UK. I figured switching off lte stopped it happening so much but then again I get 4G free and three tell me I have good signal strength for it so it seems silly to turn it off. Having said that I haven't seen it pop up once yet. Anybody tell me what the signal icons are on the G3, I have only had H so far? Cheers

I haven't seen the 4g logo yet either as I live away from any LTE areas, I've seen H and H+, 4g will show up as either LTE or a 4g symbol so I assume that your phone isn't connected to LTE/4g if you haven't seen either of those

Yep that's what I figured. Tweeted three cs but didn't seem to get much help. Thought maybe it's because I'm a SIM only customer. But I have checked there website and to all intents I should be connecting. 4G is good on my area. Not sure what else to try?

Enable fast dormancy for the 3 network. 4G works great on 3 in cities where it is supported.

How to enable fast dormancy? Website gives my area a good signal. I don't even get H+ which I did with my galaxy s3.

The option its already in my network settings menu and switched on. Are these different? Just can't put my finger on it.

I am having the same issue with my LG G3 on Three, the signal is much worse than my galaxy S3. Drops out randomly in my house and then takes ages to get a signal again.
Wondering whether to send it back our not as a phone with bad reception is kind of pointless! Anything perhaps fixable with a new firmware for the radio?

Yep exact same issues. Hoping it's not the phone (bought it myself not from three) really like it and Up to now three was great ? gutted.

It seems the phone either had really good or really bad reception. In poor area's it's quite flaky and can drop out easily when moving between rooms or even how you hold it.
If the reception is good you can get some great speeds on 4G though. Hoping they fix the issues with low signal strength soon as it's quite annoying.

Had a text from three saying they were going to fix my issue within the next seven days. Not picked up a 4g signal at all yet. So watch this space.

I also had problems with signal. I got a replacement SIM & that seems to have improved matters.
