Random loss of signal - Galaxy S III I9305 (4G LTE + 2GB RAM) Q&A, Help &

Hi guys
I am using a unrooted version of the I9305 on the EE network and I randomly lose signal. It seems to be especially prevalent when sending text messages, It will tell me mobile coverage lost and I have to reset the phone and the SMS will then be sent.
Anyone else having these issues? Any recommendations as to which modem to use on EE?
I get one or two bars, despite being around 100 meters away from a 6 sector macro site!!!!!! I used to get full reception

I had this issue randomly but not had it recently.
One time it was all day, didn't realise lol

try a different modem

There might be problems with the carrier.
Or the LTE network.

[Q] Question for Airtel users in India

Hey guys, do you know how to disable the service blasts from Airtel??? NOT the promotional SMS's but the ones that say 'You have used 20 MB of your 2004 MB limit'. Please let me know cause whenever those show up, the 3g disconnects for a few secs and those pile up on top of each other if ignored and I have to go through all of them to attend a call. Much appreciated!
Message Issue
I already had a word with airtel customer care regarding the same issue but they don't have any option to turn off those messages for 3G balance deduction. I checked my Note as well I don't think there is any option in it to turn those messages off.
Do let me know if any one gets any luck.
Thanks

i hav same issue since 3 yrs
i have had a words with then very early, but same thing i found. No solution.
Basically I am using push services, so hardly i get disconnect except changing to wifi OR service interruption. So getting msg only that time.
Actually I use 2g connection of airtel and have no such issues

Actually if it comes from same number number every time,you could black list it

I got an answer from airtel executive and that used to solve this partially. Airtel exec " sir this is because you are at place were there is access for two towers and either one will be having only 2g network as prior bandwidth, to solve this if you are not using 3g all the time switch off 3g and let the phone 2g mode. This might reduce the number of messages for you" I did so and it worked for me when am in office, when I go home switch back to 3g and this reduced those messages (almost null)

[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.
Happy Holidays!!

I'm exactly in the same situation . Please let me know if your new firmware solves the problem.

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.

I'm using it with Orange Spain. I will try using the phone this weekend with another operator to find out if the problem is operator related.

[Q] 4g data problems at home

It seems I have very good 4g signal at my work but when I am at home, it gets stuck on either 1x or 3g, according to sprint, there is 4g coverage on my house.Does anyone have problems with 4g not working properly? Its getting me annoyed since I use hotspot at my house. Any suggestions would be helpful.
I've noticed it'll show 3 bars of 4g at home, but if I actually start browsing it drops to 3g. My friend had done nothing but complain about sprints network so I am just assuming it's their problem.

I'm having the same problem! My friends iPhone gets better reception, and we both have Sprint. He gets LTE at my house in my office, but I get 3G or 1X. It's very frustrating. I may return the phone, or leave Sprint altogether, as I didn't have these problems with my Verizon Note 2.

I have used sprint chat with an agent and followed every troubleshooting method and still 3g. I will check the store to see if I can exchange it for another phone or see whqt happens
Could just be a week signal. Note that the signal bars on your phone are NOT for 4G. Check out this helpful write up over at S4GRU could help you determine what is up once you check LTE signal levels.

Almost full LTE bar+LTE signal booster and some calls not going through?

I've been stock, Dynamic Kat, Fire Kat you name it.
So long story short, I have little to no signal in my room (2/10 calls will go through) the rest will go to voicemail and won't even give me a notification someone called. I also don't get any data or extremely slow when I'm lucky
So I tried the T mobile LTE signal booster and I can finally get data on my phone at slow speeds of 3mbps or even goes to 1 sometimes (I get 8mbps in the living room)
So now I still get random voicemails from my job or friends, I don't know how often this happens but it does happen....I always see a random voicemail without my phone ringing Wierd thing is I get FULL LTE or 4G bars
I tried using wifi preferred for wifi calling and cell data preferred and still happens, I even reseted my APN by deleting it, turning it off and taking the battery out so the APN would reset (I also added 80 to one of the apn settings, seen a thread this would help with texting and receiving mms) Do you guys use ipv4 or ipv6?
. I never had a problem like this with AT&T do you guys have any idea what could be wrong?
I kept having this problem.. Long story short.. I swapped note 4s thru tmobile and no longer have that issue.. All I was getting was voice-mails and text messages sometimes from people that called letting me know they called

Cell connection issues

Me and my girlfriend have been having a bit of trouble with our T-Mobile Note 4s. Sometimes I have full 4G and can't make calls or send text but I have fast data connection, sometimes I have full 4G and then the 4G drops and I can just call and text and not have data and it last until I restart my phone. This will randomly happen 10+ times a day and it is not a fun process.

It would help if your were to tell us where you are, I.e. location, city, state. Did you have this problem previously with tmobile using a different phone? Do your have this problem everywhere you go?
Is the issue only at your home? Bad sim ?
