Dear forum elders, dear friends,
About 1.5 months ago I bought 1 Mi 10T, 8/128 device and until 2 days ago, the strangeness started in the device, which was working flawlessly with everything;
By the way, for 1.5 months the phone bootloader was off and I was using everything original.
When I was shopping after work, I noticed that the telephone network was gone at the grocery store I entered, there were frequent commutes, I didn't care much, but when I had a job with mobile banking, the situation got serious. My line is Pttcell, by the way ....
I asked the informal cashier friend if the operator and his phone were working, Turk Telekom and he said it works (Same infrastructure)
Then I went home and saw that the network had improved and I thought it was a temporary problem until I got back to the market place ...
Afterwards, a fire fell into me, as you know, the device is abroad, a long time passed and a sudden malfunction started ...
What is written above is the occurrence and development stages of the fault, by the way, in the device; no tumble, fall, crash, dislocation, change, dye under the skirt, etc. You know, if I drop it for once, I won't be sad ...
Then I talked to the supplier and got advice, he is a friend who does not understand much about this business, he only sells, but he said that such problems are usually software and if I open the bootloader and do a repair, the device will most likely be fixed ...
In previous tests, I found that the device had no problems with the capture, and usually stuck in band1 (2100), band3 (1800) and band7 (2600mhz). The application I use for this is "Network Cell Info Lite" and after unlock / repair it is widely used as "Network Signal Guru".
I am dealing with semi-professional repairs myself. Normally, such errors are caused by the IC called RF_Amplifier and pass as an antenna problem, the device loses the network unconditionally at all frequencies, the call is interrupted, etc. But in band 3, 1 and 7, the device has no problem, so neither draw nor break, etc. While at home, I actively use everything including VoLTE, I do not have access problems and interruptions.
When I manually switch the network to other modes Except 4G and 5G, it completely goes away. In modes such as 2G (GSM - Edge) 3G (HSDPA - WCDMA), there is no network signal on the device.
After trying with 2 more operators and clarifying the situation, I decided that there was a baseband malfunction and wanted to share the situation with you, dear Masters. If there is anything you want to ask or want me to try in detail, I look forward to your valuable help / comments and suggestions.
Transactions made so far;
Originally, 2 types of sim cards have been tried with Vodafone and Turk Telekom, both have the same symptoms (I couldn't find Turkcell, but I don't think it will change the result)
Bootloader unlocked, repaired with original QCN, repaired with Qcn taken from a different device, the result is still the same ...
The questions in my mind;
Does modem software cause such a problem?
Is there a possibility that it is from the Modem Chip?
Are there any chances of it being one of the Network Switchers (IC)?
If you encounter this kind of problem and have a solution, I expect your help, otherwise my new phone will be a very expensive tablet ...
Best regards.

Hello,
Sorry if this question has been answered elsewhere but I am a noob to this site. I have looked -promise!
Basically I have had an XDA Orbit on O2 UK which I have had for over a year with no problems. Recently I changed contracts but kept the same phone and O2 sent me a new 3G sim card.
Now when using the device for a long time (such as wi-fi, reading a book in Microsoft Reader, making a call) the phone will lose the phone signal and slow down. If left it will sometimes recover and get a signal again, or sometimes it keeps searching for a signal for a few minutes and then resets itself.
Sometimes when it is searching for a signal the top area of the phone gets warm.
I have tried a hard reset but this has not solved the problem. Is this to do with the 3G sim card? Should I try upgrading the ROM of the radio stack? Or would an entirely new ROM help?
The version details at startup are:
IPL 3.04.0001
SPL 3.04.0000
GSM 02.67.90
OS 3.4.0.0
Please help. Thank you.
Try to upgrade your Radio ROM. That can be a good solution.
Cheers
Thanks -I will try that tonight.
Ok I have updated the radio ROM and I still get the same problem. It will be fine for a bit but then the phone will lose signal, keep searching, and eventually reset itself.
Would using an entirely new ROM help or is the fact that this was not fixed by updating the radio ROM indicate that is this more of a hardware problem?
The details at startup now look like this:
IPL 3.04.0001
SPL 1.11.0000
GSM 03.21.90
OS 3.4.0.0
Thank you.
Yes... That looks like a hardware problem to me, since you upgrade your Radio ROM.
But for a last test you can flash a WM6.1 ROM and see if the problem is the same.
If it maintains then is surelly a hardware problem.
Cheers
I don't usually post on these forums but have been a reader for some time!
There are some things you need to know about 3G before you use this handset with this sim!
it's against your terms and conditions to use a none 3G handset with your sim 3 can and will cut your number off (ive seen it happen)
secondly 3 only have 3G netowrks they use orange's masts for when customers drop out of signal range to 2g. Hence your using orange masts which take it from me are rubbish! they have some of the worst reception in the country and ive only recently stopped selling mobile phones i doubt they changed much in 6 months!
to cut it short you need a 3G phone to go with your 3G sim im afraid this handset is not capable of 3G .
Hi thanks, for your comments.
I am not using a 3 sim card, it is an O2 3G sim card. I have tried today to reflash the O2 UK ROM image with the original settings to see if this helps but it still spends a long time without a signal and resets itself when it cannot get a signal for a while.
Is anyone else using a 3G sim card in this phone?
It worked well enough for me today to ring O2 and ask them if I could be "downgraded" to a 2G sim card. They said that they don't even do 2G sim cards anymore, but they said if I go to O2 store they may have a 2G pay as you go sim, and instead of activating it they could transfer my account details over to it. Anyone heard of that before?
When I went to the shop they said they didn't have any 2G sims and to reset the phone and try to get the settings sent to the phone from O2 online. Which I have done but surprise surprise no luck -not that I really believed the guy in the shop anyway but thought it was worth a try.
Any comments or suggestions?
Thanks.
Just to update, I have tried so many different things to get this fixed but it seems as though the 3G sim card is not the problem, as all fixed now by buying a replacement battery.
Now the phone works fine all of the time -it does not lose signal or anything. The old battery must have been faulty.
I do not know the exact fault but my guess is that when I turned the phone on at startup it was ok, but then as soon as I did anything it was drawing more current/amps from the battery it generated a fault which then made the phone lose signal and eventually reset.
I'm not sure on the science of it all exactly but it buying a new battery on ebay for £7 has certainly fixed the problem.
The Orbit/Artemis works fine with a 3G USIM -they are backwards compatible with a 2G SIM card and this obviously was not the problem.
Hi.
I have a similar problem... my o2 xda orbit for the last few days keeps hanging and reseting. It takes some time for me to be able to turn it on again.
even if i take out the battery and put it back in again...
Is this similar to what happened to you?

I think that I had the same problem but with a normal 2g sim. After an
intensive use over 1,5 years my Artemis p3300 had low signal and frquently resetting. I resolve all these problems changing the battery with a new one. It's important advise all Artemis owners that a lot of problems can be due to an old battery!
Yes that's basically exactly what happened to me. It would lose signal, keep searching then eventually reset. When I turned it back on it would still not have a signal and would take lots of times of turning it on and off before it would settle down again.
I bought a new battery from ebay for £4.95 (+£2.95 p&p) and now everything is working fine and has been for over a couple of weeks.
I had tried changing the ROM and still had the same problem. I would advise you to get a new battery and try that.
Hi, I am from CZ... - P3300 by Vodafone CZ
When I connect to wifi I sometimes lose the signal for phone.. One time I lose signal during the phoning and sometimes I lose signal when I use GPS...
Phone is 1,6 years old...
It is the same problem, isn't it?
It's a pity :-(
Can you give me an advice where I can buy the best battery? Should I buy a battery in CZ (home) or in abroad I can find cheaper and better??
(sorry about my english)
Yes that sounds like the same problem to me, I got a new battery from ebay because I thought it would probably be cheapest.
Try Vodafone first as they will be able to sell you a new battery and it may not be too expensive.
Hi,
I bought a HTC touch hd about 5 months ago, which i lost about 1 month ago. I phoned orange and told them to cancle my simcard, i didnt give them an imei number (obviously cos i didnt have it), just my lost phone number. I bought a HTC touch dual from ebay the day after which has been working perfectly. Then a few days ago, my friend phoned me saying he has found my touch HD, i got it from him, put my simcard in it and i got signal and was able to phone people from it but when i did a soft reset, it didnt get the signal back, there was just an exclaimation mark (!) next to the signal meter in the task bar, when i go into the phone settings, it says "no service" and when i click find, it says "cannot register to network."
To confuse the situation even more, when i turned the phone back on a few hours later, i regained signal and was able to phone people, but as soon as i did soft reset, it lost signal again. Over the past week i have been constantly testing it and have noticed that if i turn the phone on after about 5pm, it gets signal but as soon as i reset the phone, it loses signal again until 5pm the next day. i know it sounds strange but thats wot happens.
Iv just unlocked the phone to all networks (using the xda tool ) and tried my o2 sim in there but that does exactly the same thing, i will try it at 5pm tomorrow. Iv tried phoning orange but they are useless, and the staff in their shops just tell me to phone customer services.
Also, i can use GPRS/HSDPA all the time and go on the internet and stuff, everything on the phone works, except the actual phone itself (unless i turn it on after 5pm and leave it on, will only lose signal after a reset)
Would this point towards them blocking my phone? cos i always thought, once your phone is block, it will never get signal unless the imei is changed.
Also, is the imei on its own IC inside the phone? Does anyone have access to a service manual or at least know the circuit location of the chip? im an electronics engineer and have the facilities to change and read small ICs. If the worst comes to the worst, i will change the imei with either 1 from a faulty touch HD or from my touch dual, whichever is easier.
1 more thing, dont post telling me its illigal to change the imei, i already know, its illigal to download copyrighted stuff, break speed limits or take drugs but people still do it everyday.
Thanks in advance to any help given
Mr Moo
NEW IN THIS THREAD?
PLEASE READ THE FOLLOWING BEFORE REPLYING
PLEASE NOTE THAT THE PROBLEM HAS BEEN FIXED WITH AN OVER-THE-AIR UPDATE BY GOOGLE. IF YOU SUFFER FROM THIS PROBLEM THEN YOU SHOULD WAIT FOR THE UPDATE TO ARRIVE ON YOUR DEVICE.
Full details:
What the problem is
The device has an issue of volume acting strangely. Most often the volume mutes very quickly. Sometimes the volume starts 'jumping' between muted and loud very quickly.
This volume issue happens often during phone calls, using internet or receiving SMS text messages.
Some users are also reporting that when calling, they can hear 'radio interference' sounds.
The device is often unresponsive while the problem happens. Power button not working for the brief time has been reported.
How it happens
The problem happens while the device uses GSM 900 network, that is when the device is in 2G.
Your phone is on 2G when it uses E (Edge) and G (GPRS) connections, both data and mobile. If data is used, a small letter near signal indicator points out what you are connected to.
The problem happens while another device that is on GSM 900 is nearby and is transmitting in 2G network. This happens even if Nexus itself is not using any networks at the time (such as when radios are off and the device is in Airplane mode).
The problem is more evident when user is in low-signal area and more 2G information is transmitted.
The problem also happens in bootloader and is not the fault of Android 4.0 itself.
Please remember that the problem does not happen for all 2G networks, some 2G networks (especially outside Europe) do not use GSM 900.
How many users are affected
Every Samsung Galaxy Nexus handset seems to be affected by this problem. Majority of users however are not encountering the problem due to not using GSM 900 2G networks.
2G networks working on GSM 900 are majority of Europe, Africa, Australia, Middle East and large part of Asia.
In UK, the GSM 900 is used by O2, Vodafone, giffgaff, Tesco Mobile.
What Samsung and Google are saying
No official statements from Samsung other than asking people to send details of the problems on their customer support e-mail ([email protected]).
Samsung did post a quote on their Samsung UK Facebook wall that says 'We are aware of the volume issue and have developed a fix. We will update devices as soon as possible.' This quote is said to be originating from Google according to Samsung, Clove, androidpolice.com and The Verge.
Google employee has confirmed in an Android developer chatroom that Google is developing or has developed a software fix for the problem.
Another Google employee, Dan Morrill, shared a post by Lee Johnson on his wall and said that he is very accurate in his estimation about how software can fix this hardware flaw.
Google has replied to a customer support thread that there is a fix and it will be rolled out in the coming week. It is possible that the 'coming week' refers to week starting 5th of December.
What sellers are saying
Handtec and Clove conducted additional testing on the devices and both found the volume bug to exist on their devices.
Handtec stopped the shipments after the problem became widely known. Samsung Distribution also stopped shipments for sellers few days later, delaying shipments of the device for a week.
Clove stated that according to what they heard from Google, that a software fix is being worked upon. Clove stated that according to their sources the problem is in software and not hardware. Clove has not gotten this information from Google or Samsung directly however and refers to their inside research about information found online and their own sources.
While it was originally believed that the shipment delays are because of Samsung flashing the devices with updated software that will fix the bug, the new devices shipped on 29.11 also carry the bug according to Clove. It seems Samsung held the shipments to give Google additional testing time with the fix and held back possible refunds and replacement handsets would have gotten had the shipments not been held back.
Is it hardware or software problem?
All the tests conducted by many users so far indicate that the problem is in hardware and that the device receives signals from 2G that it should not receive due to not being protected from radio interference. This is also shown while the device runs in bootloader.
Many engineers here and in other forums and social networks say that a cheap hardware shielding would fix the problem easily, however Samsung and Google intend to fix the problem with possibly as valid means through software.
If the software fix manages to patch the problem, then it really does not matter if the problem was in software or hardware, as long as the device works properly and there are no after-effects, since some users fear that the software fix of a hardware might cause additional battery drain or unresponsiveness problems. But this is merely an opinion, we will know more once the patch is out.
The flaw is confirmed to be a hardware flaw by engineers, as well as a Google employee (referred to above). But both state that it is common for this type of hardware flaw to be patched with software and it is likely that many devices you already own have such patches in place without you knowing it.
What you can do
Wait for the update to arrive on your Galaxy Nexus. Google is slowly rolling out a fix to all handsets right now. Make sure you have internet or data connection for the update and have your phone in a charger just in case while updating.
Have it on mine
bought from Phones4u in the Trafford centre, Manchester
This looks really bad. While I am sure many people who don't have this problem won't even bother to vote in this thread, the fact that there's just one vote for someone who does not have a problem, is a surprise. I expected 50%-50% at worst.
Bought mine from O2 store in Liverpool. Problem continues even after factory reset.
Phones4u market street manchester.
I also posted the problem on Samsung UK Facebook page, those of you who have a problem should post there too so they are made aware of the problem. This might help get to the bottom of things quicker.

Anyone reported to Google support forum?
dont have the device yet so would be hard for me to respond when google asks for logs etc. That would be the best thing to do though.
According to this video, it seriously looks like a hardware issue, so letting us know where you got the phone would be even more helpful.

Thanks for the video.... Looks like I gotta be grateful I can't get the Galaxy Nexus yet. If its sw, i expect an update soon... But something tells me, its a hw issue in a certain batch.

I haven't noticed any problem with my phone but I have locale installed so I'm not sure if that is masking the problem.
to those trying to replicate, try turning off wifi, then disabling 3G (settings - wireless & networks - more - mobile networks - use only 2G networks). When it connects, get some data going (load a large website for example), or make a call, see if that sets it off.
it may not work 100% of the time (if it's really radio interference, there are a lot of variables) but it seems to be related.
I do have this issue. Got mine at the launch event at the Oxford Street Phones 4U.
Anyway in the other thread it looks like people are narrowing down the problem to something related to 3G or Wi-Fi signal. I think that might be the case since it had only happened to me while I am outside and not connected to Wi-Fi. (I use JuiceDefender to automatically disable Wi-Fi if it doesn't find any known spots)
I got mine from Oxford St. too. Same problem here.
Sent from my Galaxy Nexus using XDA App
had this problem yesterday with my vodafone sim.
been using it with my o2 sim today and not had the issue occur.
doubt the network would be an issue but thought i'ld just throw it in there.
yep, I have the problem too. I got mine from Phones 4 u On the lauch day in Oxford Circus. Hope this is not HW related!
I seem to have this problem intermittently. Thought it was just me doing something wrong.
Got mine from O2 over the phone.
I'm assuming it can be fixed with a software patch.
Im also having this issue. Purchased from phones4u today 19th nov 2011.
Dosnt happen all the time though. It did happen when i had my old desire next to it and was loading spotify on my desire....
What software version does everyone have? Hopefully the next (assuming 4.0.2) will fix it.
Hi guys.
So I've been going through the painful process of logging a network fault with vodafone here in Australia, just to be told 10 minutes ago that my job has been closed and put down to a handset issue.
My issue is probably best described by this little video I've shot of my phone in action: https://skydrive.live.com/?cid=abebdf487d4ef439&id=ABEBDF487D4EF439!849
As you'll see, in the browser I will click a link and the loading bar will show that it's starting to do something. Reception will sit on 3G (no loading yet) flick to H (no loading yet) flick back to 3G (no loading yet) and then back to H and will load the page. Now I understand that going between 3G and H is normal behaviour, but in my situation not a single iota of data is transferred until it's gone back and forth, often taking 5-7 seconds for each request.
Now here's the odd part that makes troubleshooting really annoying. Putting another vodafone sim in my phone has the same problem. Putting my sim in another vodafone handset works fine. But putting a Telstra (our countries biggest telco with a 3g network that trumps everything else in OZ) sim in works flawlessly with pages loading instantly, even midway through an 3g/H transition.
I have updated to 4.0.2, experimented with various radios all to no avail. Vodafone has told me to take it into a store for them to deal with, but I'm really not keen on trying to convince a salesman that I actually have a problem and then being without a phone for 2 weeks, only for it to be sent back after a reflash with the problem remaining. Does anyone have any other ideas before I bite the bullet and take it in?
I'll have to bump this one, any ideas, anyone?
final bump
Hi Hinee,
I live in Argentina and I'm suffering the same thing. I used to have a Nexus One and 3G worked perfectly, now since I made the change I'm having the same issue you described. As you did, I tried with different radios to no avail.
Now, I find curious what you say about the SIM cards because it relates wot what I read in another forum. I just found a post somewhere else (sorry I didnt save the link) which says that the age of the SIM card may have something to do with the issue.
I haven't been able to test it yet, nor do I know enought about cellphones to know if its coherent or not, but I'll be calling my carrier today and ask for a SIM replacement to see if that solves the issue.
I'll let you know if that works for me.
Hello guys. I have some major issues with my S3. In general it has very weak reception compared to my S1. I've had two providers KPN HI and Tele 2, the latter uses t-mobile's network. With both providers and several different sim cards I encounter the same problems. Not only is reception in general weaker than my S1, it also drops calls very frequently. Mind you, I live in central Amsterdam, where I've never had reception problems with any provider at all. Sometimes when signal drops it comes back after 10 to 20 seconds. Sometimes it's completely gone and I have to reboot the phone to get service again. On average, I have to reboot the phone 6 to 8 times a day. The phone is on stock rom, latest firmware.
My s3 has been to samsung repair two times. The first time they checked for software issues. After a week they told me they couldn't find anything wrong, but they updated to the latest firmware. The problems were still there. They then took my phone for 3 weeks. When I got it back they couldn't say if they found the problem, but the phone went through general inspection (?) so it should be fine. Wrong. Literally one hour after having back my phone I tried calling someone. I was standing outside, had 4 bars of reception, but got dropped out of the conversation after 3 seconds. The no service symbol was showing. I rebooted and tried to call again. This time it worked. After an hour I checked my phone and surely, the no service symbol was showing again.
I'm getting very tired of this. I have a 550 euro phone that doesn't make me do phone calls 2 out of 3 times. People calling me have complained that they get voicemail instantly. I called Samsung and they told me they couldn't do anything but take the phone in for repair again. The shop where I purchased the phone says the same thing. I have no choice but to send it to repair, which means that I will lose my phone for at least 3 weeks again.
If someone can offer me advice, please, I would appreciate it very much. I wish I didn't gave away my s1...
Edit: Should've posted this in the general s3 sub.
Ask them for expedited repair and shipping, Samsung does a pretty good job and helping out when you're nice and friendly with them.
Let them know the situation, tell them you don't want to cause any problems, but that this is the third time you've sent the phone, if they can kindly either do a more thorough review of the phone and figure out what's wrong with it and fix it or give you a different new/refurbished phone. Or something.
