My friend have this phone, who can suggest me best custom ROM-kernel to flash? He is now using CM7(dont know what release) and he has some issues with gsm, loses signal, don't accept 2nd generation of networks, only 3g (and 3g in my country isnt that good for use of 24 hours ) . Thanks in advance.
EDIT: It's problem with very weak signal, not even 2nd or 3rd generation. Just loses signal, and after that come back to 1 or 2 bars and that is maximum signal strength. But on other phone, it's full with same SIM card. I have Sony Ericsson and never had this problem with signal or something like that.

I use CM7 almost 1/2 year and I have no problem with 2g or 3g. Most of time I use only 2g (to save my battery) and it works without any signal lose. I think it could be HW problem.

Yes totally agree. Using cyano ( arco's mod) since last year and so far never had such kind of problems.

It's not HW problem, it vas branded by one serbian carrier and it wasn't unlocked so that was the problem. He solved by sending to service center and they unlocked it succesfuly. . . Tnx for replying. . .

HTC HD 2 - Drops signal completely when held!

Just got my HD2 on Vodafone.
Signal is fine when the phone is stationary, but when I hold it.. it drops from 4 bars to either 1 or none.
I have:
- Disabled data/3g/hspda etc.
- Tried many different radio's up until 2.12.50.02_2 (which is an improvement but it still happens)
- Updated ROM to latest Energy Series.
Am I right in thinking the phone is faulty?... or is this common?
Thanks
Hehe, this is ridiculous. I believe HD2 has one of the best signal reception among the smartphones. My signal has always been great so I believe your phone is faulty. My 2c. Let's hear the others.

That is normal, our big heads are blocking the signal, but seriously, the "bars" are misleading, thanks to all those Cingular commercials , it really takes good signal quality to get a good connection, not good signal strength ...
So if the bars are dropping, and you cannot use the phone then that is a problem, but if the bars drop , and the phone/data/whatever works fine, then it is not really an issue ...
Just as an example, when I am at the college here, I have only one bar, but I am on hsdpa, and get like 2 meg of data, wish it was hsdpa+ but that is a diff story, and the phone works fine with only 1 bar, now inversely , people on VZ where I am at have 3 bars and their data is sooooo slow, and they drop calls ...
p.s. if it is dropping to none, check your area make sure they are not upgrading the towers, it is happening a lot and often here in the US in some areas ....

Yeah it's dropping to the point it loses signal, I try to call my mobile from my landline and I get the answering service.
What's really strange is, I just put a T-Mobile sim card in... and when I hold the phone, there's no bar dropping at all.
So in summary.
Vodafone Sim:
Stationary - 4 bars
Holding - drops to the point of no reception
T-Mobile Sim
Stationary - 4 bars
Holding - 4 bars

Different Freq's , so the tmo signal is just stronger where you are ....
is it a TMOUS HD2 ?
If it is , they do not support the same freq's as the EU models, for other providers ....

No it's not the US one.
So.. combination of hardware fault and weak signal?
wrong forum. this should be posted at the iphone4 forums.
the HD2 had to be one if the best reception phone and i am sure many agrees.
Just phoned up Vodafone to see if any problems, and they said there are no faults in the area at all. They said it was probably the handset but I explained that I had tried with a T-Mobile and Orange sim with no such problems.
They then said they'll send me out a new Vodafone sim card as they suspect that could be the issue. And that could take up to 5 working days... taking me out of my 7-day cancellation period, so naturally I said no thanks.
Going to head into my town center and pick up a Vodafone sim from the £1 shop... if I still have that problem I'm cancelling as I can find the same deal on Orange.
Question...
Has any one experienced a sim card being at fault for bad/dropping connections??? Seems complete rubbish to me, especially seeing as the sim is new...

Still manged to have it lose signal completely whilst the phone was in my hand writing a text.

that's weird.... vodafone do seem to be generally piss poor for signal...despite their claims of being one of the best.
Id still suggest letting that radio settle in for 48 hours our so.

I'm going to change to 2.07.51.05 / 2.09.51.03 and leave it for a bit then... are there any higher .51 radios?
Thinking I'm going to end up canceling contract, if .51 works it's going to restrict me from using certain roms .
Sorry about my earlier post, I could have sworn, it was said earlier that it was a US model ...
Wow ,screwed the pooch on that one ...

Help me please: Losing signal more than 20 times a day.

I'm from Brazil and having issues with Nexus S since I bought it.
Before, I was with KB1 radio and could not have GPS fixed and was losing signal several times a day.
So, I updated to KB3 and it fixed the GPS issue but the network signal issue remains or even got worse.
I'm losing the network signal more than 20 times a day and the only solution are reboot.
Could someone help me please?

it could possibly be the signal towers, most likely it is.
you can also try to flash back to a stock ROM + stock Radio and see if it fix itself up
Can I put the Galaxy S radio in Nexus S? Because we have Galaxy S here in Brazil.

very simply... no.
try the JK8 radio? or try flashing a custom ROM to see if its a firmware related problem
also verify your KB3/KB1 packages with MD5 hash to verify its 100%
I'm having that problem also in my nexus S and on my wifes Galaxy S
BOTH are stock roms. Really weird. It enters like 1 or 2 times a day in "Emergency call only mode". Weird thing is: signal bars are FULL but emergecy only text on my lockscreen.
My carrier: VIVO, são paulo, Brazil.

I'm using CM 7 stable.
It's a radio issue for sure.
Nexus S is coming to Brazil next month. Let's see which radio it will use here.
Its really cool seeing us brazilians talking here... You know, I dont have these problems at all but sometimes the 3g bars greys and than reconnect again. This just irritates me when on youtube, when streaming is interrupted.

Hi,
You are at Oi, and we are at VIVO. MAybe it's a issue with VIVO carrier.
Here in Rio, using TIM.
Sometimes I get signal lost, but it comes back without needing a reboot.
At work, 3G signal is very unstable. Leaving my Nexus at the same place/position, I get two bars of 3G signal, then suddenly full EDGE signal, then it comes back to 3G.
At home, I get 3G all the time.
There's another thing I've noticed: sometimes when I receive or make a call, after I hang up I lose connection (3G or EDGE). It takes about 10 to 15 seconds to recover it.
I have a Nexus S i9020, 2.3.3 stock rom and radio.
We have to know if that happens in the US. If yes it is our carriers, if not it is our basebands.
Im going to leave oi because the 3g speeds are horrible the max i got was 1030kbps. At Vivo speeds can be 2 times (Or more) better!!!
Sent from my Nexus S using XDA Premium App
Bad news for me: I've tried today all radio baseband avaible in XDA and all of them I got signal lost during the day. The worst KB3, K8, K1. In this order.
I don't know what more can I try.
If It won't be fixed soon, I'm sure my next phone will be a iphone 5. I love Android but can't deal with their bugs.
This is issue of the VIVO in some estates like Sao Paulo in a lot of phone models. They just knows about it, and they are correcting this issue.

But why only by rebooting the phone whe can get again the signal. Signal drop is a carrier/network issue but cannot reconnet to network it's a phone issue.

Remembering my ancient knowledge about cellular networks, a cellphone sends a registering signal to the radio-base station from time to time. If the RBS doesn't acknowledge this, this cellphone will lose signal. When you turn off the phone and turn it on, you are forcing a registering. Maybe then the RBS registers the phone, and then you get signal.
What I'm trying to say is that maybe it's not a cellphone issue, maybe it's an operator issue.
Have you tried using another phone with your SIM? Do that and check what happens.

Yes. Before the Nexus S I had a Motorola Milestone and It never happend.
When it lose the singal, the Nexus S can identify the RBS but cannot register. Even If I restart the radio with an app or swtiching to airplane mode and switching again to normal mode, It can't register. What the diference of restart the radio or reboot the phone? Is it not the same "force"?

Xperia play reception problem ...

Hey everyone and tnx for reading this.
I am experiencing some reception problems with my play today.
Just started to happen today.
Here is wat happens. Out of no where (and i really mean out of nowhere!) the phone has no more reception or connection to 3G or wats so ever. Ithe icons show a diff story. The reception level is full and then internet is showing 3G as normal. But i think they hang. Cuz when i use data the 3G icon changes to H.
anyways this has happened over 10-15 times during the past ten hrs or so. My friends are saying ur phone was off or out of service and im at home where i always have perfect reception.
I didnt install or remove any app.
I didnt play with settings.
I try putting it in and out of flight mode. Sometime it worked. Not everytime tho.
I tried restartung the phone. Reinserting sim and batt. Also tried searching for network manually. But i keep losing reception. Any idea?
Thanks

G is slow speed.
E is medium speed.
H is broadband speed.
Go to wireless and networks to change to GSM only (permanently slow but better reception) or WCDMA only (permanently fast but probably worse reception based on how developed your carriers communication infrastructure is).

He was fine bue wen he tried calling me mine said its out of service. Also i couldnt make a call to him. A few mins later everything got fixed and again it got messed up. As i said at all time the reception bar is full! But its not real since i jave no rec.

GSM and WCDMA work differently and independantly. Your old Rogers phone probably worked using GSM.
WCDMA is not as well supported and could be considerably worse reception even though it is with the same carrier.
Go GSM only and note if the reception is better.

Ye i understand. I'm just trying to throw some idea in the air to help you. I can understand how much of a frustrating problem it could be.
Lets' clarify -
1) You bought Xperia Play, worked perfect
2) After a month, your phone shows a good signal, but when friends telephone you it goes to answer machine as if you had 0 signal?
3) Basically all reception is lost and you have no signal, but sometimes it shows you do, even though you dont.
Here's some things to try -
1) Put your sim card in another phone and note the behaviour. Does it stay a strong signal? If yes, then it has got to be the Xperia Play at fault.
2) Put another sim card into your Xperia Play. Does it stay a strong signal? If yes, then it is actually your network provider at fault. If no, then the phone is at fault.
3) Try resetting the whole phone to default. Does the problem persist? If yes, then it is a hardware fault. If no, then problem solved.

Thanks a lot. I did restart it to factory defult yesterday! didnt help! I even reinstalled the whole software using SEUS. nothing is changed.
I know the service provider is fine since my friend sitting next to me had perfect signal. he is also using the same network as i do.
now I am jus waiting for my brother to come home. he has the arc. same network. im gonna double check the sim cards and if its the phone i will send it for repair!
I am having the same problem with mine and reception, I don't know if 85dbm is supposed to be good but I am used to having full bars in my house. I only get about 2 now.
Reception for me is terrible. Used to be a lot better on my crappy old samsung gravity.
Drops to zero bars constantly, and often says no service when inside the house.
My wifi stops working the second I'm out the front door too. Wifi works fine across the street for all my other devices, including a laptop and a samsung captivate.
This leads me to believe the radio transmitter is a defective design. I'll be calling my provider tomorrow.
Edit: wifi doesn't work now at all.
The phone's wifi icon shows it as connected, but theres no transfer of data, router doesn't see the device as logged in.
Some google searches have revealed this to be a common defect. I for one am not pleased.

Just holding the device lowers signal!!!!
I know that sounds like crap but in the instruction manual it says not to cover the back fo the phone as it affects the signal.
No two ways around it, the phone has issues. I have taken it to carphone warephone and shown them it going from 4 bars to 1/0 bars just buy holding it. As it is over 14 days I am screwed. Whats worse it tha that had stop selling the phone to new customers as it has so many issues.
If you look at your battery life, then click on it you get the graph which shows signal. On mine were it say awake / screen on. i.e. you are holding it, the colour goes from bright green to dull green in perfect unison.
I am currently on my 2nd phone, the first one had 5 different faults. I now have 4 batteries due having to use moxier mail as the stock mail is sh1t. unhappy times

Hi guys!
I'm sorry to hear about your problems with Xperia PLAY.
I would suggest that you try some things before considering leaving it into your retailers for a check by a service technician.
Double check that the problem is not caused by an old SIM card. Old SIM's and new phones can sometimes cause troubles. So please try with a later SIM card if possible.
If that doesn't make any difference you could reinstall the phone software or update to Android 2.3.3 which is under launch right now. When the update becomes available for your device differs from market to market and is also depending on operator customization.

I changed my router to 802.11G only. I have devices that do not support n so i went with G. it took a day or two but but it fixed it.
to get it working when it does that you have to disconnect and then reconnect.

Losing signal on my Nexus S

Hey everyone,
I just bought a refurbished Nexus S for $200. I thought it was a pretty good deal. Loving the phone so far. However, last night I lost data services. The signal bars which is normally green was "greyed" out. I tried the web browser, twitter and nothing was working. Eventually I got data back in about 30 mins or so. I didn't think anything of it. Well, it happened again today. Signal bars were greyed out again. I have less than 14 days to return/exchange my device. Should I exchange it? Is this a known issue with the Nexus S? Just an FYI, I have 2 lines and data is working fine on my BlackBerry.
I'm running stock OS, 2.3.6
Any help is greatly appreciated.
Thanks
Hate to break it to you but one of the few bad things about this phone is its reception. Check what radio version. Your on. If it doesn't say ke1, go on peter alfonsos web site and download the ke1 radio and flash it through cwm. See if that helps.

I'm assuming that requires me to root the phone? So if I choose not to root my phone I'm going to have this ongoing issue?
rooting and installing this radio won't necessarily help. I have the I9020A with the newest radio and i do have this problem sometimes - I'm losing signal and it recovers in random time. the weirdest thing is that I can find my network when I'm searching manually for networks. You are on rogers (based on your avatar), so i can only guess we have the same model. My brother has the I9020A also, and he has similar yet different problem - when he lost signal due to no reception areas, he has to go into airplane mode and back to normal to recover the signal. he also has the newest radio (UCKF).
You should also notice that rooting your phone will make you lose your warranty, and i guess that also the the right to exchange it.
Yes the model I have is the same as your brother's. I know in general Samsung has bad radios. Is it because it's made by Samsung or is it particular to the Nexus S? I have been reading the same issues with the Galaxy Nexus, so I'm guessing it's Samsung.
I don't plan on rooting it because I know it will void the warranty and I won't be able to return/exchange it.
i have same case , which is , when i am back in my room ,away from streets and lots walls for signal to go through , 3G signal is **** , however, you can switch it to 2G signal in order to no to miss any phone calls and SMSs. but , you Internet speed will greatly reduced ... like max 8 kb/s

You should see if your phone is set to wcdma/gsm mode. My room is a inner room also and when it loses 3g signal, it jumps automatically to gsm mode (internet speed is not an issue, WI-FI FTW ).

Well I do have an ns4g and since these forums aren't seperated by model its easy to see why I would make the wrong recommendation. What are you following me around? Instead of being a troll why don't you post something useful and try and help the op bud.

What Radio do you currently have?
I usually had this problem and I had to go into mobile network settings, uncheck 'Data Enabled' and select 'Network Operators' until it found my carrier.
Have you tried checking the Airplane mode and disabling again?
If you dial *#*#4636#*#* when this happens and you go into phone information, do you see it connected?

[Q] N910U On T-Mobile/ Weak Signal/ dropped signal issues

Hey guys just wondering if there are any exynos users who have T-Mobile in the USA (Atlanta for me). Im using the n910U and i get a 4G signal pretty much everywhere but out of nowhere it will drop to 1 bar, and then drop signal all together. Its getting quite annoying as it was said that the unlocked version was supposed to work with T-Mobiles LTE bands. It also happens when using the download booster which is also a pain. Any suggestions on improving the signal? thanks in advance.
Bump. Anyone have any advice to remedy this?
Im planning on buying the sm-n910u aswell but I want to use it with metro pcs which should be using the same network as tmobile, I dunno if ur problem is the phone or network hiccups but im hoping it will work here in nyc

A few things to look at
Try 3g only awhile, you may have a marginal 4g signal and the phone keeps switching back and forth
Try to find out which bands are coming off each tower in your area as well as tower location
You are one of the first to use the new intel modem in the usa for this phone
Keep us posted
Back in the HSPA days I had nothing but international devices and frequently experienced what you described. All the carriers have different networking h/w and topology because they all grew through acquisitions. If I left my home town where I had decent coverage when my flight would land in another region I'd have to reboot my phone to get it to connect to the network. When doing speed tests with friends using "real" AT&T phones their phones were always faster and more reliable. It was only an issue less than 10% of the time so it wasn't a big deal (to me). For better or worse the carrier's optimize the radios in their phone for their specific networks. So, at least in theory, a carrier phone (used on the carrier that provided it) is always going to deliver the best performance.
I got my N910U from Hong Kong, and my 4G signal is as weak as hell, though i'm a China Unicom user.
My iPhone 5s has much better signal than it, same SIM same network.:crying:
There must be something very wrong with the Exynos version of Note 4.
Hope Samsung could fix this ASAP.
Yea it happens pretty randomly in my house and when i leave to drive around town. The signal will be 4 bars on 4G then suddenly just drop connection all together for about 10 seconds. its a real drain on the battery when it does it so often. Im wondering if its a software issue with the radio in the n910u? Since we have root already we can load a different radio on it and see if it improves?
Got the same thing going on with my 910U on Fido Network in Canada. I must note it seems like it doesn't affect performance except for a network speed, no issues during the calls but 4G signal is at 1 bar most of the time unless I'm outside in downtown or something. I must note 3G signal was almost always at full strength. Not sure what is going on here but I thing we really could use some modem update here lol

I also have hongkong N910U model and facing signal issue on regular basis. When Problem appear I can not receive calls anymore and when try to make call , signal disappear altogether. After I retry a couple of times then it works fine but only solution is a restart to get the full strength. it feels like it is a software issue rather hardware but still keeping my device in observation. I feel when I enable power save mode only after that this problem appears. trying not to enable power save mode and test the issue for few days.
Kindly also share your own experiences to solve this issue temporarily.

If have exactly the same issue !!!!
Start with full signal strength and going down to the lowest strength and minutes later no signal !!!
Reboot or Airplane mode can undo this, but the cycle starts allover: Full strength, less strength and no signal.
Tried with 3 different carriers !!
And 2 Note 4's !!
I have the Snapdragon version SM-N910F
What is going on ??

Swapped the note 4 again.
The third one and a new simcard fixed the issue !!
3 to 4 bars signal strength/
I have this problem since yesterday, it seem like the Note 4 is dropping the Sim card. In panama we have a provider that will need to register the sim card with names and stuff but i never did and every time i turn off the phone it will pop out that menu from the sim card.
Yesterday it was popping out every 20mins so i assume that the note 4 is dropping the Sim card. i didn't have that problem when i started using it. its been only a week and this problem came out. I got no signal, with the circle and a dash to full signal and drop signal back... all day, I can't even play online or watch youtube or other things. But it work fine with wifi!
I changed providers no more issues for me. Gonna change back next week and a new simcard also
I am in Colombia and my phone always is with one bar of signal, but when I am making or receiving a call it get full bars of signal. Do your phone do that? (I have the N910U)
