Hi guys,
ive had my exec for about 2 weeks now. In the last week it has started to randomly loose network signal. It keeps searching till you either soft reset it or turn flight mode on and off. It will find a signal in about 10 seconds after that.
Is this there a 'dont keep loosing signal' setting that im missing?!
Mine does the same thing - annoying as hell! Not worked it out yet.
Are you talking about telephone or GPRS signal ( U or G )
Phone signal
everything! it looses all signal.
I called o2 and they want me to go into an 02 shop for them to have a look at it before they give me a replacement
The are all 'handset trained' apparently.
I also called o2 a week ago stating the same problem, They gave me a refferance number and said they will look into it, But of corse 1 week later they have not called me, So this afternoon i will find the referance number and give them a call.
I will post ther Bollox answer on here tonight

Same problem here with a MDA Pro. I ahve noticed that this happens when I am roaming in Germany as well. Very anoying. That and the thing freezing in a call and needing a re-set. This is my second one as the first one the screen portion became loose, happened on the one before as well.
I have the same problem althoughmine will refind the signal after about a minute. It seems to disappear whenever I ask thephoneto do something new (open a program etc).
I finally persauded T-Mobile to exchange mine so I'm getting a new one delivered tomorrow.
I'll let you know if that fixes it!

My XDA2 used to lose its ability to communicate if I was out of a signal area for more than 15 minutes, but I haven't had it happen yet with the Exec. A soft reset or Flight Mode on/off cycle would fix it.
It is frustrating but didn't happen often.
Well i phoned o2 and they said there was still no answer and that no one else had complainded about this, So i told them of this forum......
As per the last post i have also had this on a 2 and 2i, and i gree if its out of servie for a few mins its seems to give up looking for service until you reset.
mine has done it overnight befor, i looked befor going to bed and it had just the 3 dots flashing where the aerial should be. the next morning it was still the same, quick soft rest and into full service, thats when i first rang o2
John
I've had this on all my XDAs in the past, and seems to continue with the Exec.
Very annoying, but not sure what can be done about it.

guys,
wait for a rom upgrade from o2, ( with new radio rom)
that should solve the problem.
happens with xda, xda2, skipped xda2-i and xda2-s,
and now it's back.. :roll:
Hi Guys, I have been having this problem for weeks with my MDA Pro. I convinced myself it wasn't the phone and that it was T-Mobiles Network. In desperation last night I spoke to T-Mobile about the problem. They told me it was a faulty phone and that I would have to contact the supplier of the phone and ask them to replace it. I tried to explain others had the problem and that I wasn't happy to have to send my phone off and wait for a replacement. But no avail. So I sat down at home and looked at the settings. I think I might of cured it! Maybe it is a fluke but by clicking the signal meter and going to settings, then changing network selection to manual it has stopped hunting when it loses signal and quickly re-picks it up. HNope this helps others.

Defenitely...that did it.
I had the same in Holland with KPN: while switched to manual no more problems.
In Romania however, where I also have UMTS, I had to switch it back (or it switched itselve back, after changing SIM card, I don't remember) to AUTO.
There it switches from GPRS to UMTS if UMTS signal is OK.

Ok, i have the same problem. Have GPRS Always on set in registry and 10 minutes ago, my MDA Pro lost GPRS connection. It trys to reconnect all the time. But no Connection can be build up. After Flight Mode and back, i get a connection immediately. But on start of MSN Messenger, it loses the connection again and does the same loop like before. Only a softreset brings my connection back to live.
Looks like a ROM issue. Maybe GSM or CE.
I am delighted to say that my replacement MDA Pro seems much more stable in the signal department. Although I still loose signal ocaasionally, I no beleive that is due to poor signal area and not the phone...
If you phone isloosing and reconnecting all the time then like mine it is probably faulty! Hopefully the ROM upgrades will sort out the last few issues I'm having!!
I love this phone!!
Same problem with JASJAR
People still have this problem? i'm using radio 1.03.01. When i used the original firmware, the phone part would lock up (Would get the busy - wait 15 seconds and try again, but it would never clear - had to soft reset)
With the 1.03.01 radio, i still get disconnected, but it'll find the signal again after a few retries - which is very bad! I rely on the phone at work, and people can't get through when it's disconnected. I have full signal strength (4 bars) so it's a software/hardware problem.
It looks like maybe it happens more frequently when charging or activesync'ing, than when it's disconnected from usb.
Can anyone confirm having the same problem, and it getting better or FIXED with the new radio firmware? If not, i'm going to have to return it.
Michael
I am using radio version 1.04.02 on the O2 exec, although i use a Vodafone SIM (supplied by work!). Mine suffers from the same problem, mainly at home, which is a very odd signal area for Vodafone. I can go from no signal to full signal to none again, and yes, sometimes it drops completely and needs a soft reset - bingo! full signal again.
Switching the network type from auto to GSM does seem to make the unit a little happier, but i need to use WCDMA when possible, so i leave mine on auto and live with the dropouts!
Lets hope the next rom fixes the problem.
Cheers

I have the same problem with my XDA and O2. a soft reset nor a full reset have been able to fix the problem. :roll: is the new rom version available as yet?
I have had my dual for the past 3 weeks and it has done great (even with out 850 on the AT&T network).
Yesterday I took a driving trip to another location (about 2 hrs). The entire trip down I was monitoring the connection on the phone and it had ok connect. At one point I made a call on the phone and it was great call quality. About 20 min later I went to make another call and the phone had not connect (radio Icon with constant dots or !). I thought I had just wandered into an 850 zone. So the entire drive back I had no connection (where I had had it on the way down). Even at my house I have no connect. It will not connect with the AT&T network anymore. I called AT&T and "registered" my IMEI number just in case they had locked me out (they said they did not).
I have taken my SIM out of my Dual and put it into my Cingular 8125 phone and it works like a champ.
I have also done a hard reset on the Dual.
I hope I did not throw $$ power the toilet.
Any Thoughts??? Any logs to look at??

Same with O2-Germany
Same issue here. Using my Dual for 2 days now. Everything worked like a charm (phone, 3G-internet) and then I was travelling by tram (few km) while surfing and then... you know it.
No connection for several hours, network scan shows all available networks, but connecting failes. Several soft-resets didn't help either. Done a hard-reset a minute ago: didn't help. Using the same SIM in my old Magician I experience nothing but a fully working phone.
So... I gotta return that Dual to O2-Germany tomorrow, hoping to get a working one soon.
Cheers,
jekk.
//update
just got connection after a soft-reset.. but... here is how:
1. soft-reset
2. entering PIN
3. Dual searches...
4. And after 3-4 seconds, it connects!
5. after again 3 seconds it recognizes 3G
6. after another 3 seconds it looses the connection. Damn sh*t.
// another edit... looks like this is becoming a monologue, uhm?
Since I do not want to give my Dual back to O2 I searched a bit and have come to this solution:
Changing the phone settings does the job. Go to Settings->Phone->Band and choose the appropriate values. In my case there are W-CDMA issues, since sticking to GSM solves my problem. Nevertheless, this is not the way I wanted to use the Dual, if I CAN have 384kbit (no HSDPA around), i WANT it. End of story.
Tomorrow I'll tell O2. I promise.
// update 3
This is obiously turning into a monologue now, but now I know why:
This wasn't an issue with the device. After calling the hotline several times, it turned out that my access-rights to the umts network were altered accidently. The man on the phone did a usual check of this today and changed it instantly and after some minutes the problem and was gone. So to summarize:
Everything is fine with my touch dual.
I own a Verizon Motorola Razr M, bought in ebay to an US seller. I am in Spain and I use Movistar SIM card
The phone came with stock JB 4.1.2, and therefore I could not unlock the bootloader.
I started using it, but it had a problem that I am not been able to solve so far: after some hours of use, with no problems with GSM and data connections, it suddenly looses both connections, although the signals on the status bar still appear. I take care that signals have gone when I take the phone to make a call or surf the web.
I have tried the following procedures:
Change the net settings to GSM/UMTS
I rooted the phone with motochopper 1.1.2 exploit
I installed Safestrap 3.12 in order to be able to install other available locked compatible roms.
I tried these roms, following this thread here in XDA: Clean ROM 1.0. Clean ROM 1.1, Barebone New Base, Stock Deodexed.SDswap-Locked & UnLocked BLs-xt907-9.8.1Q-94-1, but no luck. This last one uses the last radio, but no way.
I also installed the [PATCH][GUIDE] Patch to fully enable GSM on Verizon CDMA Android phones. I could only install it on Clean ROM 1.1 however. It has been impossible to install it on the other ROMS. In any case, no luck again with the patch installed. Here I had a big problem because as I still had these problems, I got into *#*#4636#*#* in the dialer, and touched the band selection option: suddenly, the net showed no signal more and I was unable to make it work again: I finally solved this by installing the stock firmware from here with RSD lite.
No way. I still have this problem and I can not use the phone. I have also tried with another SIM card, but the problem remains. It is a shame because when the connection works, the phone runs very well.
Any help would be very appreciated

The problem also seems to become worse with the use of the phone: at the beginning, coming from a factory reset, It can last some hours before the problem occurs. But since it happens from the first time, it happens more and more frequently and the phone can not be used any more. It seems that there could be a software issue.
Another try disabling fast dormancy
I´ve just disabled fast dormancy, because my operator Movistar apparently does not use this technology.
For this, I have modified 3 lines from build.prop system file, as indicated in another site.
The 3 lines are:
ro.mot.ds.fastdormancy.disable=true
telephony.lteOnCdmaDevice=0
ro.telephony.default_network=3
Having fast dormancy enabled when your operator does not support it, seems to drain battery, and could cause other problems. That´s why I´ve done this. I have used root explorer apk from Google store, it is free and it automatically creates a backup of build.prop file when you modify it.
I keep the fingers crossed, let´s see what happens.
Fast dormancy: yes but...
After some days using the phone with fast dormancy disabled (for this, I also added this line to build.prop: ro.ril.fast.dormancy.rule=0 ; I read this for ICS Roms, I do not know if this command is also valid for JB, any comment will be welcome), I still get some cuts (less I would say), but at least the phone tries to restart the connections. For this, I have also installed the apk from Google Play called 3g reconnect.
In any case, any comment would be appreciated.
Issue not solved
I still get data and voice disconnections when I use GSM/UMTS or only UMTS modes. They occur ransomly, and they also occur as soon as I use a WIFI connection. I can only use the phone on GSM only mode, which is frustrating.
Any advise?

I do not go near *#*#4636#*#* anymore. So tell me do you use that to make these changes (phone info is the app name).

Hello,
I have tried both: using *#*#4636#*#* or using the usual phone settings. Sometimes I have also checked that the changes made with the usual settings appeared also dialing *#*#4636#*#*.
Yesterday evening, I tried selecting global mode instead of GSM/UMTS and it seemed to work for some hours, but today morming, the problem occured again. So far, the unique way I have found to avoid connection cuts off is using GSM ONLY mode. I have to say that I have tried with 2 different SIM cards but the result is identical.

Did you select the 3 dot menu & mess with the "band" settings?
---------- Post added at 07:08 AM ---------- Previous post was at 06:56 AM ----------
http://forum.xda-developers.com/showthread.php?t=2346623
I did that once, and all the signals disappeared. I restored the phone with RSD Lite, that appeared to be the unique way to have again signals working. Now I do not even dare touching these 3 dots.

What booby a trap? How many step into!
I don´t know if I am understanding you. I did that once because I did not know what else should I do to solve the problem. I saw that there was the possibility to choose theoritically between US bands and Cellular, and I entered in that menu. It is not so stupid to try that if you have already tried 100 other ways.
In any case, anybody has an idea about how to solve this problem? I´m sure I am not the unique person having this issue with this phone.

You are saying the problem is now still there. Yet the radio partition is fixed. Please restate what has been fixed with the rsd flash & what remains unfixed.
Well I think I have fixed and solved the problem: I initially copied the APN settings I had with my previous HTC Sensation, because the phone operator was the same (MOVISTAR), the SIM card too, and I have not moved. In these APN settings, the proxy was "undefined" as well as the proxy gate. I wonder if the radio stucks looking for a proxy each time or whatever. I tried yesterday with completely different APN settings, with a concrete Proxy and a gate... and now I have not had any issue in the past 24 hours. I will still wait a couple of days to see if that was finally the reason.
Which in any case would be silly, because I just applied what was working OK with my sensation, but...
New APN settings: let´s see

After several days, the problem is still there. After setting new values in APN, it happens less often, but it still happens. I have to switch to GSM only mode.
2 days ago, I was surfing the net at quite high speed with no interruptions, for half an hour. I then shutted off the screen, on again some seconds later, and the connection was blocked, I had to restart the phone. It has to be a software issue.
I finally sold the phone
After concluding that I could never get rid of this problem, I sold the phone, informing that he would have to use mainly GSM only connection. Great phone otherwise, but with this issue.
This sounds like a Baseband Issue.
Europe I have found baseband:
sm_bp_101031.027.32.81P to be the most stable so far, with no H+ support though.
But most Carriers in Europe don't have H+ or LTE.
That baseband is part of build 9.8.1Q-66
Which can be all downloaded here:
http://sbf.droid-developers.org/phone.php?device=8
The baseband from 98.16.1 had H+ support in Europe but connections dropped like crazy.
Same with 98.12.4, we remedied that with Aussie Radio at the time.
Maybe this may help some International users with Data and GSM Loss

I'm on 9.8.1Q-94-1(98.30.1.XT907.Verizon.en.US) and wanna use it in Germany. any experiences with the radio compared to the suggested one. Or is there another way to boost the performance of the razr m? Compared to my razr I the signal and data quality is really poor...
edit: my baseband-version is: SM_BP_101032.021.32.80P
edit2: ok... now i've flashed several basebands... and the behaviour of the phone is always the same... with the australian baseband of xt905 it wasn't possible to get an hspa-connection. dunno if its enough just to flash the radio-fw?!?!?
so is there an other way to get more stability in my region? i tried to flash the radio from razr hd retail germany. but i think the razr m don't like it when I fool around. actually I love the mobile, so i don't want to make it angry... your suggestions are very much appreciated...
On the latest M5 release, and every nightly before, the phone cannot get a GPS lock if it's on LTE. If I go to the network settings and switch off LTE and use 3G, it gets a location lock. Is there anything I can do to fix this?
Note: I'm using the Note 3 for Sprint. No custom Kernel.
Any ideas?
Tried doing a factory reset, but problem still persists. Does anyone know where I can report this?
I know this is an old thread, but maybe this will help someone in the future if they Google search (that's how I found this while looking for a solution). This advice worked for me:
Use root browser to edit the last line in
/etc/gps.conf
The last line will be
LPP_PROFILE=0
Change the 0 to 3. Save and exit.
In advance I will like to appologyse for my communications skills as my english is "NOT VERY GOOD LOOKING".
I can 100% comment on a FIX for the GPS signal lost, many of us have been having this issue for the past few releases of 12.1 - 5.1.1 cianogenmod and I believe I finally found the reason.
When the new system updates gets done the update changes automatically the type of connections that you phone will pick up signal from the towers and satellites. When there is not satellites available it does pick up signal from towers and then based on that compute a calculation and makes a faster FIX that takes 14 seconds at its worst.
So based on that principal idea I went inside the bands and type of connections in the test menu that is in (*#*#4636#*#* ) without brackets and noticed that my phone was set to pick up signals only for LTE/GSM.
This is because this two kind of signals are the most common now days but it is wrong especially for Canada that actually has so many towers with 2g, 3g and CDMA type of conections.
I did a test and inside my home was not getting a FIX picking up just 2-3 satellites and not getting a FIX IN LOCATION, but my new not 4 was so QUICK that I decided to give it a better range of connectivity for tower calculation and went ahead and changed the option to WCDMA and LTE wich are the ones I have notice work the best... I put the one that had the most that includes WCDMA/LTE/GSM etc and ever since it works better than my new note 4.
1 - #*#*4636*#*#
2- Phone information
3 - Set prefer network type.
3 - WCDMA/GSM/LTE
4 - get out and reboot.
This should fix it PLEASE REPORT BACK if this works for you let's keep helping everyone.
Hi there,
First of all, I ran an extensive search over google and also on XDA forums before posting this.
My S4 (I9500) is experiencing random data connection drop problem for some time now. It starts with no data transfer (upload/download arrows not being active), then connection goes from H+ to H, then to 3G, then drops, back to H and continues until I turn off and on MOBILE DATA from toggle buttons. Then it works normal for some random time, then it happens again. Sometimes an hour, sometimes after 5 minutes.
I found this thread , however trying the workaround there by entering the provided code, I get "Connection problem or invalid MMI code". So that fix is not working either. I tried to go in service mode > debug screen > nas control and change revision to Release 5, but it says NOT SUPPORT. Haven't tried the other releases since I dont want to mess with it. I am also aware that the workaround in the above thread is for S2.
When this happens, it is just mobile data, there is no problem with network signal.
Has anyone else experienced something like that on their S4s?
The method you tried using is probably outdated and for a different phone.
Are you sure it isn't your provider?
Did you try another modem?

Nope.. I am working for a service provider company. Other people with iPhones in the same location as I am, are not experiencing the same thing. I heard similar problems with other S4 users, but they dont know any workaround either.
I tried both auto connect and WCDMA only options as well. Doesnt make a difference. My S4 doesnt support LTE, so I only have 3 options, third as GSM only, which I don't think it would be a solution.
Only temporarily solution so far, is turning mobile data off and on, which lasts from 5 minutes to 1-2 hours.
Btw my android version is 4.4.2
