[Q] My XT890 drops GSM connection irregularly - RAZR i Q&A, Help & Troubleshooting

Hi there,
I have the xt890 / razr i phone. So far, I'm very pleased with it. Recently I have discovered a bug with the GSM /3G connection. This happens once in a while (approx. 1 per week), I don't know what is causing the problem:
The GSM connection drops, that means the phone is then "offline" and the red triangle with the white cross is showing on status bar. I then have to manually remove the sim card, put it back in to the phone and enter the PIN. Only then the phone connects again to GSM.
Otherwise the phone is working fine.
What could this be?
I'm using system version 91.2.26001.xt890.retail.en.EU (Android version 4.1.2) on Swisscom carrier.
Kernel: 3.0.34-gc6f8fd7
build nr: 9.8.21-50_SMI-26.1358455837
Thanks!

I had similar problem: turned out to be a connection problem of the micro sim card and the phone. Cleaning the sim card, replacing has solved my problem.

I used to get this a lot because illy classes are in a building with no reception. Fix was easy, just enter airplane mode and exit back out, you should get your connection back

[Q] SIM card reading problem

My i9000m on the Bell mobility network is not picking up data after an overnight charge with the phone turned on. Today - nothing. I do have phone use and I can access data on WiFi.
I am running stock ROM. I unlocked the phone using a Rogers SIM card, about a week ago, but went back to the Bell network immediately after with no problem. After unlocking I got the Kies to work and updated to UGJH2. Since then, the network access has been spotty but I've switching to WiFi then switching back and it's coming back. I purchased this phone with a different Bell SIM2 then put my old Bell SIM1 (from an Omnia2) in this device.
*#7465625# shows Personalizatiob Status
network lock [OFF]; Network sublock[OFF]; SP lock [OFF]; CP lock [OFF]
What I've tried
1) Switching to WiFi and back - no data
2) Putting SIM1 back into the Omnia 2 - O2 booted up and accessed the Bell network including data. CONCLUSION - The problem is not the SIM card.
3) Putting the SIM2 into the i9000m - no network access at all; not even phone. This SIM2 is working in the O2 and originally worked in the i9000m. Much to my surprise when I put SIM1 back in the SGS it still picks up the Bell network.
4) Squeezed the SIM holder blew out with compressed air in case it's just a physical problem with the SIM being held tight enough - SIM1 still not picking up data.
So it would seem that there is a problem with my SGS reading SIMs other than the one in use when whatever happened happened. Any suggestions on how to get other SIMs, even from the same network, to work? If I have to submit my phone to Bell I need to re-lock it. How do I do that?
Thanks for the help.
--- update---
relocked the phone using *7465625*638*# then 302610 and my unlock code. Power off / on still no data access. Now *#7465625# shows Personalizatiob Status - network lock [ON]; Network sublock[OFF]; SP lock [OFF]; CP lock [OFF]
first try this
http://forum.xda-developers.com/showthread.php?t=789039&highlight=*#0011#
does it show which band it is using for data?
you can also try this
http://forum.xda-developers.com/showpost.php?p=8124344&postcount=45
install the APN on off
then flip it on / off and back to on
see if that helps
Thanks for the response.
I did the #*0011* It's flipping between the 850 on 5 and 1900 on 2 The DL and UL numbers are slightly different. I did have to reconnect to the APN.
How would this affect installing *other* Bell SIMS? That's what worries me the most - that it wouldn't read another Bell SIM that works in another phone.
the only time i see this happen is if you swap the SIM card when the phone is ON
if you turn off the phone, change between SIM1 and SIM2, then turn it back on, you should not see that problem
I know because i was playing around with multiple SIMs when we were researching the Unlock methods for this phone
I take out the battery before I change the SIM. I have to for the Omnia 2 so I just got in the habit. This is sounding worse and worse
although I was rushing off to work so maybe I didn't - hope springs eternal.
----resolution ---
sometimes you just have to call Bell, wade thru the 1st level support and get to someone who knows what's up. Apparently my phone plan changed today (I didn't know it was post dated) and the data feature was not provisioned even though it's a plan that includes data. The guy invoked the feature and poof - data. yay. AllGamer, thanks for your help.
you'r welcome
I did have the same problem, using 2 numbers from 2 telcos, both sims work fine on my iphone but I9000 fail to recognize 1 of these 2, no matter how I tried, I actually did all crazy things like insert couple paper layers between the sim and the sim slot to create additional pressure on the sim contact circuit.
Suck thing about this is non-recognizable sim has data plan with it, which I want to use on I900, finally I asked the carrier to issue a new sim and all thing work fine. It's a new sim type anyway. You may want to try this if all other means doesn't work.
The fix is easy I use to have a moto milestone and when this happened a simple reboot fixed the data connection.

[Q] S III mini network issue

Hi guys,
I own an i8190, baseband : I8190XXALJL and I encounter frequent network outage.
Although the signal strenght indicator shows 3-4 bars, I cannot be called, cannot call and data is not being fetched.
On battery usage app, the network is most of the time "green".
On any other phone around me (blackberries, iphones, SGS II and III), and on the same network the problem does not reproduce.
If I turn the phone to airplane mode, and then back on, I am able to call, send mails so on and so forth.
Does any of you have the same problem ?
If any of you updated to I8190XXALL2, is this problem still persisting ?
Should I send it to the service ?
I'm currently running the ALL2 baseband, but previously had both the ALJL and the ALK6 ones and didn't encounter any such issue...
Before sending it back you could try with a different SIM card, maybe yours is acting up (it sometimes happens, especially with old SIMs).
Seeing how nobody complained of a similar issue though, I don't think that changing your baseband will have an impact, but if you'd like to give it a try you can download original firmwares (that contain the baseband) from here: http://www.sammobile.com/firmware/. In order to install them, just follow the steps in the root thread.
Will do so. I'm going to pit-stop my SIM card @ Vodafone and let you know about it.
It's strange that this happens only deep inside buildings (eg. offices, malls, etc..).
When this happens, usually the data activity indicator disappears OR the S3 mini is using 3G frequencies (not H, not G, but 3G)
Just changed my sim card and the issue still persists...
It's driving me nuts. My feeling is that the S3 mini doesn't lock on a network cell when 2 are available with similar coverage.
Will upgrade to the latest build and let you know about it :banghead:

And now the handset runs XXALL2 from vodafone uk.
I'm curious if the phone will have that network issue furthermore.

So far there's no difference. Where I live the network coverage is pretty bad, but it doesn't "disconnect in the background".
Only at the office I can test it out for sure or inside massive buildings.
ci6i, go ahead and update; install kies (for drivers only ), get odin3 1.87 and flash it with XALL2 from samfirmware.
Lately I see there is XALL3 available for some asian countries.
I still think that my BlackBerry 9810 is a tank. unfortunately vodafone romania doesn't sync emails two ways via BIS so... :crying: I had to get back to samsungs...
Well, i understand to lose signal if network coverage is bad, but my phone gets "network stuck" in the middle of town. I noticed this few times: at job, the phone stands on the table near me, and i receive sms about missed calls (i have voice calls diverted to voice mail when unreachable). If i try to call or browse the net at this moment, it's impossible until i set airplane mode on then off. All this time, the phone shows full network signal and HSPA data connection.
I'll try to change the firmware after hollidays.
As mentioned above, try to change firmwares (to XXALL2), I've also noticed some network drops when I'm at home (however this is expected in my case), but when I installed this firmware, I noticed some signal gain (full on 2G and +1-2bars on 3G signal).
Hi again.
The same issue even on xall2
Just happened again today in a crowded place.
It goes to "3G" from "H" and then it's gone off the network.
Will try with XALL3 although there is a small improvement concerning "sticking to the network carrier". It seems it'a hard job to get a call when in coverage area...
If still no success, I'll loose my patience with this Sammy...
See ya!

You get SMS because they use a dedicated network bandwidth for this technology and apparently the S3 mini does not loose connection on this communixation channel.
It appears that S3 mini is dropping voice and data, but not sms and CB (cell broadcast).

LJL version. No drops. Sometimes when i am on edge of 3G coverage area

Hi, i also have the problem with vodafone Romania. I can't place calls or use data connection. After reboot everything is ok. I tried to switch to Airplane mode and back, but no results.
Same problem over here

Hi bogdangr,
I have the same problem with my SIII mini. From time to time, after working normally, it loses the H or 3G symbol and shows about two or three signal bars, but if I try to make a call or receive one the operation fails miserably. The airplane mode trick doesn't work for me, and I have to reboot the phone to get it working again.
I've updated to the latest official firmware, but the problem is still there. Have you found a solution for this or anybody has more ideas of things to try?
Thanks you all,
MFC
I'm on VF RO, too.
Crappy phone, what can I say.
If it can't follow a network where there is sufficient coverage...

Hi Miguel,
The only workaround for this issue (at least for me) is to keep it in GSM mode (no "AUTO mode", no "WCDMA only").
So the crappy phone won't have to switch frequencies and I can get phone calls (I start considering a luck when the phone rings...)
I'm on 4.1.2 now baseband I8190DXALL3 (latest on samfirmware) and still the same.
You just don't want to know how's everything downloading limted to GPRS
BR,
Bogdan
Does anyone know what's that *# code that enables service / engineering mode ?
I want to select on which network frequencies is the phone allowed to work.
I want to disable 3G mode and leave GPRS, EDGE, and HS(D)PA only.
The reason is that when the issue appears, S3 mini switches from "H to 3G" and "G to 3G" and then it's gone;
Although there are moments when it can fetch data with network on 3G coverage without problems...
The code is *#*#info#*#* but it doesn't work .
I don't think it's a good ideea to disable those settings. Maybe it's a temporarily problem and i know Vodafone is testing/launching 4G coverage.
For me, this network issue is happening once in a week. How often do you lose phone signal ?

I found out the service code but the RF setup is not "sufforted".
Vodafone has implemeted already 4G in selected areas but it's not about that. On blackberry, iphone and nokia this is not happening.
As a frequency... 3-5 times a day while I'm at the office.

[Q] Network Issues

Hi guys,
I'm having network connection problems I recently purchased my RAZR I, was informed it was unlocked,
however when I insert my 3 sim, I get the message " Cannot connect to network at this time, please try again later" !
The phone doesn't display any sim error messages, I've purchased a 16 digit unlock code, in case its locked,
but am unable to enter it into the phone as no error screens pop up, I've tried android codes which are
supposed to "call" the "enter code"scene, but without success.
I can't find a working code for the "engineer mode" either....
I've changed radio mode to "gsm only" (I'm in the UK)...
I've rebooted, factory reset....etc etc
Phone info screen states... Network unconnected
GPRS. off
I'm at a loss... How do I remove the "little red triangle", emergency calls only & connect to a network so I can use the phone.

Which software is installed?
Which provider do you try to use?
Is the sim card working in an other phone?
If you manually search for a network, do you get any choice?
Phone is running stock ROM ... Jelly bean.
I'm trying to use my Three Network sim which works fine in other phones.
I've manually searched networks... Results show 3, Vodophone, o2 & Orange... Selecting 3 brings up same "cannot connect at this time...." message.
I've checked APN settings, they're as they should be !
Thanks for quick response...

Which exact software is running? Please the full image string.
That would show for which country/continent the phone is setup. Maybe you also just need to call Three Network and ask if they see some error on their side.
Stats are as follows...
System version
91.2.29001.XT890.Retail.in.GB
Android
4.1.2
Kernel version
3.0.34-g261995f

Build number
9.8.21-50_SMI-29.1359955748
As the phone won't register on the network, Three are unable to test the connection ! Plus my sim works in all my other phones.
The RAZR I is reading the sim as my contacts import to the phone, so I don't think the sim jacket is at fault either....
Hope this helps...

Oh ! I've also checked the IMEI number online & as far as I can tell its not blocked...
Come on guys any ideas.....
Sent from my HTC Desire using Tapatalk
No idea now. It could be a broken phone or a broken sim. Maybe one metal contact on the SIM is broken, or something like that.
I've been in touch with Motorola, there answer is a factory reset.... I've tried a few sims and all are recognised ( the associated APN loads every time...) but still no network connection. I've also checked the antenna connections to ensure contact is being made....
Could this be a software issue? The phone is rooted, can I use ADB to alter IMEI ?
Thanks in advance...

Red cross emergency only

so i did an RSD LITE / MyTool to re-Stock phone.
after Re-stock and get phone working.... 4 times a day i see a RED CROSS icon with no signal and tells meEMERGENCY ONLY Calls.
i has to place phone into AirPlane mode then off to get it to go away or wait 3 min for it to go away. then works fine....
is there away to fix this?
what can i do? its a Motorola Atrix HD Android 4.1.1 Blur_Version.98.5.38.MB886.ATT.en.US
i notice that every 13 minutes NOW, that this is the Reason i get no service:
every time i see the Red Cross logo my Network switches from GSM PRL to LTE/GSM/WCDMA once it goes to LTE/GSM/WCDMA i get no service.
so this tells me something is missing from somewhere. i think that after i Restock it something did not go in?
HOW DO I FIX THIS ISSUE? you would think that it should not be GSM PRL it should be working on LTE/GSM/WCDMA right? so why does LTE/GSM/WCDMA crash it?

I've had that problem before when it was all stock, no rooted and it was really annoying.
I couldn't find way to fix it so i bought another SIM card and it worked perfectly. Maybe you can try buying another SIM card or flash stock again

I re-stocked it & cleared the modem settings using fastbiit abs erased everything from system to boot to modem and after re-install now I get red cross and lost of signal more.... I think I might get new sim and try that

UPDATE
ok so like i been getting that Red Cross Icon & loseing Signal for No Reason right?
ok so i did some testes. i did a SIM Swap so check if it was the sim.... hours later poof its back..... :crying:
so i did some more tests... i got an H2O Wireless sim loaded $10 on to it & from 10pm to 11:39am i did not loes signal not once & did not get that red cross. with the net10 i got it like 5 times every hour. so this tells me 1. Net10 has faulty sim or 2. net10 is kicking me off the tower or 3. my phone is not net10 full compaitble or 4. i stated to Notice this issue AFTER i used up all my 2.5GB of 4G LTE. so i think that is going on is that im now registed on the network as a Badwith hogger so every few mintues they will toss me off to make sure im not streaming or downloading a big file. this makes more since they everything else. so at the end of my billing i shall switch to Cricket Wireless GSM and see if it happends again. :fingers-crossed:

[Q] droid turbo network problem

I bought my Droid Turbo about two weeks ago to use it in Europe. I checked all freq and bands of my carrier and I also spoke with a guy who is using Droid Turbo in my country (Poland), all was ok. I got my phone and before inserting the sim card I updated to lollipop 5.1 OTA. After inserting my sim card the phone detected my sim and connected with network (LTE). I thought that everyting was ok untill I started using Droid Tubo in a daily basis. The phone is constantly switching networks. Its loosing lte signal switching to 3g for example, then to gsm. After a while its reconnecting but not always, sometimes I have to restart. I was trying almost everything: wiping from recovery, wiping via fastboot, switiching network connections by hidden menu commands, changing apn settings... I noticed that my problem seams to be similar to the problem which was solved by 21.44.8 update which: "Fixes an issue that could prevent proper switching from 3G to 4G LTE. Fixes issues that could trigger a dropped call, prevent a call from going through, show that no service is available or show that a SIM card is not inserted" - this is quote from motorola update release note. This quote very well describes my problem. After doing almost everything what I could I decided to ask for your help, because Im starting to think that this is a hardware issue. I am looking forward for your help and will be very gratefull for any suggestions.

Hello, I have almost the same problem. I recently bought DROID TURBO and i was using it w/o any problem for about a month. and Poland is also my country I did everything like you including update to lollipop before inserting SIM card. Everything with the phone was ok until i tried to change cellular bands in menu to see if it will affect battery life in some way.
Unfortunately my Droid Turbo is now refusing to connect to any network. To be exact: it is logging to my network ( i have checked it on the service hotline of my carrier ) but then after about 3-5 sec. signal bars are greyed and no connection to the network. I've tried three different cards from different carriers and with all a have the same result. Now i cannot use my Droid Turbo as a phone ....... i've tried factory reset, cache cleaning, disabling Verizon apps&services .... nothing... Could someone help me/us, do you have any suggestions ?

Hello again.
The only way i've solved this network problem on non-rooted Lillipop is to install new firmware using Verizon Software Upgrade Assistant for Droid Turbo. You have to run this software and use the rapair button then it downloads new firmware and installs it on your phone.
i have same problem.
just flash last firmware with fastboot
