Random Reception problems - P3600 ROM Development

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

problem with HTC tytn hermes 200

I bought an unlocked HTC TYTN Hermes 200 from a private party. He lives about 40 miles away from where I live and he used it with T-Mobile in California (I live in California also). Before I bought it, I tried it out (while I was in the same city that he lives in) with my T-Mobile SIM and made a phone call and the reception was clear.
Since I got home, I've had problems in 2 places (home and work which are about 5 miles apart) where I have 1 bar of reception and if someone tries calling me, it doesn't even show an incoming call on my phone, it goes straight to voice mail and if I try to call someone, it doesn't ring even once, it just says call ended. When I am at other places, I usually get decent reception (but not always).
I have tried flashing all of the recent radio firmware but nothing has made a difference. I also tried inserting another T-Mobile SIM and had the same problem. My previous phone (unlocked Treo 650) had really weak reception in those same areas but not this bad. The phone is not warrantied, according to HTC. I have made sure all my network settings are correct. It's running Windows Mobile 6. I think it might be a problem where the HTC antenna doesn't pick up a signal as well as weak T-Mobile reception.
Any ideas of what I can do about my problem ?
radio version?
I've tried every version from 1.38 to 1.48 and nothing changed with all of them. Right now I am using 1.40
Hmmm...
apparently there are no TyTn HW reason that can cause this problem...
Other peoples in that areas have low signal? (obviously yes)

wife has a razr with t-mo and it gets reception just fine. i dontknow anyone else with an htc.

Have you checked to make sure all the bands are active; like it is not set to only use certain frequencies and not others?
I have the band set to GSM (vs. Auto) and band is set to GSM(1900+850)+UMTS(1900+850). None of the other band settings seem to work.
oh and I updated the radio to 1.50. There is a small improvement where my phone rings half of the time when i call my cell from another phone.
HEY
I have had a simmilar problem in California, it doesnt make sence but what I did was flash the radio to the newest 1.50 and then re-install a new rom, and make sure you set the band selection to AUTO on both. NOT just the GSM-UMTS, but also the band frequency. and then power off the phone by pressing the off button and then turning it on. I have a TYTN too and HTC should warranty it, its guranteed for 2 years. Hope this helps.
jackieboy,
thanks for the tip. what rom are you using ? I am using black satin.
where abouts are you located ? I am about 1 hour east of los angeles I just want to get an idea if you are roughly in the same area as me.
Are you with T-Mobile also ?
After you did this, how many more bars of reception did you get ?
by the way, I changed network type from GSM to Auto and the band to Auto and no difference in reception. I haven't flashed a new rom yet though.
Try oficial ROM it cames with radio upgrade and is work very good for me.Also batery time increased .

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.

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.

[Q] 3g everythere but at home????

I have a problem with my Tmobile g2 running 2.2, it is all stock no modifications whatsoever other than handcent and fancy widget.
The problem is I can not connect to 3g or hsdpa network when I am at home. By this I mean the cell tower that provides service when I am at home. I have txt and calling capabilites but I have no data whatsoever. I have to manually switch to 2g or edge to check email or use the browser. I have called tmobile and they keep telling me that the problem is with my phone, however when I am 2 or 3 miles from my house and it goes to any other tower on the planet everything works fine.
I have searched the g2 forum here but could find no answers. I apologize in advance if this has been indeed covered or discussed to death and I have just failed to find it.
I did find the *#*#4636#*#* option and when it is on 2g I can run a ping test and it finds the server just fine, but on 3g it always fails to connect. Again this only occurs of course when I am sitting at home!
Thanks to anyone who can shed some light on this or point me in the right direction because leaving it up to tmobile has proven to be fruitless.
It might also be worth mentioning that i replaced the sim card today as well, this too had no effect on this phenomenon.....
My mom's nexus s has the same problem. Only difference is that when i walk out the door i get 3g. Once i walk back in, I get edge...... I think its might be just tmobile frequencies poor ability to pentrate walls.
Sounds like a problem with the 3G network in your area, or just a weak signal there.
I know its not the signal strength, I always have full bars at home Its something to do with the network....

Full bars on 3G or 2G ? If you have full bars on 3G then it sounds like a network problem.
I have the exact same problem, but my building is probably over 100 years old with 300 coats of lead paint on it. It depends on your building. Signals can bounce off of mirrors for example and other materials. The more material the signal has to go through, the more attenuation happens.
I have a similar problem, my G2 can't maintain a consistent connection, I will go from 4 bars of HSPA+ to 4 bars of Edge to nothing (lost connection to network) and it will jump around wildly between these three states (every few minutes). My wife's MyTouch 4G doesn't do this, my G1 did not do this, our kids (dumb) phones have consistent connections.
I know it's some interaction between my phone and the TMO network, I'd say it was a defective phone except the only place it happens is inside my house.
I wish that TMO offered a microcell.
There is no reception problem, I have had the phone working here for awhile and it always has full bars, like I said I can hop in the car and drive a couple miles and it works just fine. Tmobile finally got back to me today and said they are having their Engineers troubleshoot the tower that provides service when I am home. I hope they get this fixed soon, they said 72 hours.......
It's that anti-cellphonereception chemical they put into paint!!

Intermittent phone signal

I've had my HOX now for just over a month and i'm loving it. One thing that is slightly bugging me is that occasionally the phone signal will completely cut out giving me an 'x' where the signal strength normally is and telling me that I can only make emergency calls only.
This will correct itself within 30 seconds or so and go back to giving me a signal. This doesnt happen all the time which has made it harder for me to diagnose. Do you think it is a problem with the sim card (Orange UK network) or is it likey to be an issue with the radio software?
I never had an issue with Orange on my Desire although this is a different SIM card.
Any help or advice would be appreciated.
Thanks
I think this is a common problem I'm on Vodafone and this happens to me. I applied a fix when installing insertcoin Rom a while back and it doesn't do it as often now.
I'm glad this has been mentioned now because my One X (On Vodafone) drops connection all the time. The amount of times that I have been somewhere and needed to transfer money through the Natwest App and haven't been able to is getting annoying now. As I am not rooted I can't try any fixes but I have found by using GSM only around where I live, it won't drop signal half as much or often. I don't have a 3G mast near me so its always dropping connection switching between the two as opposed to a smooth transition.
Hi,
You are not alone. I'm on Orange UK and have seen this problem on quite a few occasions. Unfortunately, as yet I can't see any pattern to understand when it happens or what causes it.
Tim
Happens to me on 3. Sometimes I have to hard reset to get it back.
Glad that its not just me. At least I can rule out an issue with the sim.
As it seems to cover more than 1 network, could it be a radio issue that is addressed in a future firmware upgrade?
It is definitely not just you. I'm in Malaysia on the Maxis network and have this problem as well. It happens randomly - at the most it happens twice in a day.
Do you also sometimes get the message 'Preparing SIM card...' at the bottom of the screen?
I brought my phone to the HTC service centre and they offered to take it in to test the radio. I will do this when I get back from my holiday and keep you guys posted!

I do get that message at the bottom of the screen. I'd be interested to hear what the outcome is once you've had your radio tested.
Yep, it's the [email protected] radio firmware HTC has provided us with. Radio 2.05 is much better. HTC are useless with updates. I've had problems with my network connection for 2 months!

Except I am on Tim @ Brasil.
This is nearly always down to signal.
If you're in an area that has decent 2G signal but fluctuating/low 3G signal then the phone will keep trying to connect to the 3G signal. Sometimes it'll be too weak and not be ableto connect and will stick with the 2G signal. If the 3G signal is only just strong enough to connect the phone will switch to 3G mode (dropping the 2G signal). Then it'll realise that the 3G signal is too weak to do anything with (showing an 'X' in the signal area) and drop back to your full 2G signal.
3G signal is breathable which means that if lots of people are connected to the 3G mast then it's signal area (i.e. distance from mast) is reduced. If no-one is using the 3G mast then it's area is bigger.
Perhaps your signal is breathing in and out of use where you are.
Obviously the radio can have an affect too, but with so many people using the same radio software there are going to be some it works well for and others it doesn't.
Personally, I keep my phone on 2G/GSM Only for most of the time and then switch to 3G when I want to use data. I hardly ever get problems with signal, and if I do I shrug and put it down to the coverage in the area I'm in.
P.S. Saying this, my 2G signal seems to drop in and out when I have WiFi turned on. Usually when I'm using wifi I'm not making calls anyway so it doesn't bother me...
Thanks for this useful info. How do I set my phone to 2g only so I can test this theory out ?

It seemed 'good enough' to me, but I only had 2 days with my phone on 2.05 and then my camera wouldn't work at all. So I sent the phone back for a replacement. Crazy it's still not fixed!

Which is correct, however any phone working correctly should manage to switch between 2G/3G without problems, i.e. you should not find the phone without a signal at all provided there is 2G coverage, which seems to be the case being reported here. My previous phones with 3G/2G never had a problem, and the HTC One X has been no different for me, it hasn't dropped it's signal, I'm on Vodafone in UK.

This is happening fairly regularly for me on UK T-Mobile. Seems to happen when switching between Orange and T-Mobile or T-Mobile and 3G T-Mobile. I've got a ROM that distinguishes between a 2G and 3G connection in the carrier name area.

It happens to me also. I'm on 3 in Denmark. They providing only 3G coverage in area. So far, I figured out that it's happening when I'm loosing signal completly (i.e. when I go down in concrete basement), and when I'm within coverage again, phone is unable to register on any network at all. Sometimes can help turn airplane mode on and off, or sometimes I have to turn phone off and on again.

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...

I'm also having the same issue. I have a maguro yakju variant galaxy nexus. I'm getting only 1-2 bars and have no warranty as I got it from ebay, gps is also showing problems, but the phone came in new sealed condition. Please let me know if there's a fix to this
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.
Thaaankss
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?
