[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.

Moto g xt1064 3G hardware problem! I guess!!

Hi all, i tried like everything turning the stock version of android like ten times, custom ROM and stock versions, but nothing 3g won't work, only E or G,,, and without turning wifi on, the bars remains orange all the time (like the network is being used)
and when i set the WCDMA only i end up without network on my phone!!
so that's definitely a hardware problem!!
so oo hhuuuu luck me!!
but, what's the fix for all this?? does anyone dissembled the device and knows where the hell is the 3g antenna or network antenna and how to order a new one and change that or fix that ??

The x1064 is the US model. There is a different global model for use outside the US. Europe uses different bands for the 3G than the US, so that might be the source of your problem.

Mi5 lte issue with all roms

Hello Fellow MI5 Users,
I am writing this thread to see if anyone else is having issues like me with my Mi5.
The problem is the intermittent signal issue with LTE, My problem started when I flashed 6.7.28 miui 8 update at first I thought that it was my Network Provider, but when I checked my dad's and sisters phones (same provider) their 4G signal is very stable without any issues at all.
So to describe my problem this is what's happening to my phone.
My phone is now running the latest Global beta miui8 6.8.12
When switching to LTE as prefer connection my phone signal goes crazy from NO SIGNAL - NO SERVICE - EMERGENCY ONLY - NO SIMCARD as I dig in to my settings i change my preferred connection to 3G Only which in my surprise works well and perfect without any issues but the problem here in my country(Philippines) you cannot rely on H or H+ at all since the network provider service sucks bigtime!
So far here's a list of what I did with my phone to fix it
- Flash back to China miui8 later version that I remembered that I don't have any issues with my LTE(Sucks because the issue was there also when I went back)
- Flash to MIUI 7 (Ohh well at this point I thought going back to miui7 will fix this issue but NO, not at all and I'm losing patience)
- Flash all KINDS of CM Based OS (Well switching OS might solve the issue, But believe me it got worst! after flashing all kinds of CM Based OS on my MI5 it all went down to Reboot forever bug (this happens when my phone boots and phone started to connect to LTE)
- Went back to Global beta miui 8 6.8.12 basedband version TH20c1.9-00038 up until now im still using this version.

Could it be you're own carrier hasn't got coveridge for LTE for your device?

In my country lte is Band 3(1800) and mi5 should support that band,right?

For me my carrier do support coverage for MI5, but just recently it went nuts

hi im using official global rom with my mi5 but i cant make native video call on my gsm operotor because of not support miui 7 and 8 so.. is there a rom support native video calling like samsung ?

Mi5 Prime user here. same problem with LTE as well using GLOBE sim, no problem with SMART so far. using China ROM MIUI 8
here are my observations
GLOBE switched to LTE - stable when stationary.. goes NO SIGNAL / EMERGENCY CALLS ONLY when moving in a vehicle
i guess there is a problem on the radio signal switching from H+ to LTE vise versa. unlike my other phone - Meizu M2 Note. no problem switching between 3G / H+ / 4G.

Sucks right? I wanted to switch carrier as well but then again, LTE coverage with smart sucks specially in my location... Hoping that this will be fix soon..
I used to have a perfect LTE with globe 4G+ after some time after updating OS version it went nuts

I updated my mi5 to miui 8 global and got 4g signal but only for a minute or less then it dissapeared and when i manually choose mobile networks i can only select Telenor 2g and 3g...really weird.

Hello James,
I am having the exact same issue on my Globe Sim. I just bought mine last week. Whenever i turn on my mobile data, signal suddenly goes to no service, not detected, etc. Its very frustruating.
Is my unit defective? Or is it just a firmware issue?

I am using both Mi5 and Redmi Note 4x. In both phones, I experience frequent network connection drops for both SIM cards in serted on the phone (one is Sun, the other is Globe). Even while stationary, I exeperience the network drop where the signal bar for both SIMs suddenly simultaneously disappear. The network drop is worse when I am mobile. In addition, the network drop is causing the app I am using at the time to restart. PLEASE HELP.

hi.. is this thread still active? have you found the solution?
i am also from the Philippines, been using globe for 2 years in mi5 with no connection problems, then recently, when i try to connect to data, the signal goes on and off just like yours.. just this month, i updated from miui7 to miui9 and the problem got worst! when i connect to mobile data, phone reboots after a minute! i tried every fix i found in the internet (reset APN settings, factory reset, airplane mode) but nothing seems working.. So i tried Sun as my other network and it works perfectly fine.. Also, i tried to interchange sim 1 and 2 slot but still not fixed.. Another thing, when i turn the data in different place, my connection seems okay.. i live in cebu city but works in lapulapu.. the problem occurs in lapulapu..
help! is this network related or somethings wrong with the phone?

Good to see this thread. I thought my phone had a factory defect.
based on my experience.
version 9.1.1.0 and below only loses signal for globe while on data connection in some locations .
higher versions up to the latest(now is 9.5.5.0) causes our phone to totally reboot in some locations as well.
maybe it has to do with the signal/radio frequency on the area for the identified carrier(Globe).

this is easy.
root then disable LTE band 41

Question Mi11 since 4 Weeks - My Problems

Hi ,
Since 4 Weeks im the owner of an Mi11 .
Unfortunately I have to say that I am very disappointed with this Device .
My Problems are :
- very poor WLAN Receive Power ( maybe the Antenna ) , i change my AVM Fritzbox against an new one , but still the same Problems . Mesh Thettering / Switching dont work perfectely . With my Company Phone , an Iphone 11 the Mesh Roaming works like charm and it receives in my kitchen 560 MB/s with the 5GHz WLAN.
My Mi11 drops down in Kitchen, wich is 3 meters away from the Fritzbox to 10MB/s or it loose the Connection completely . The Mesh roaming dont work too.
Till the Mi11 change to my Repeater the Bandwith goes down to 5 MB/s the maybe it switches to the Repeater who can deliver again 500 MB/s .
- Poor Mobile Network Power . I loose the Connection on Calls on Places where i can take Calls with my old Huawei Phone.
Am I the only one with these problems or do others feel the same way?
Thanks
Michael

I don't have such WiFi issues
and regarding mobile data, are you using the same operator and SIM card as in huawei?

Ok , Hmm . I use the same SIM as under the Huawei Handy .

for wifi -> i have the same, disabling WPA3 helped a little on my fritzbox but not in total
mobile --> the same, i have my company pixel 5 next to my mi 11, both have deutsche telekom sim, pixel is having a much better signal and also gets higher download speeds

Clear system cache, network reset, clear sim card tool kit data, check Access Point Names, replace sim card.

Also, try to adjust the incoming signal throught the hidden menu of which your sim approves.
I dont have these problems with my mi 11.

I have my Mi11, since the beginning of last month, and i must say i never experienced bad wifi/cellular connection. So i suggest you make a network/factory reset..

I think Xiaomi's European models have problems in all areas that the Chinese models don't. My CN model has fantastic WiFi values with both the original and the Xiaomi.exiaomi.eu ROM. I also have the Fritzbox as a router.

i need better signal,

Question Big issue, No Data during a call.

So One thing I discovered on this new phone of mine is that although working perfectly there is a major flaw in the way Internet data works during a phone call.
Any time you make a call, the phone downgrades the active signal from 5G/4G to H or E ( GSM).
Which in turns cuts off the data.
If I force 5G or 4G, then the phone call cannot be made. It just disconnects.
I have tried all settings, Volte enable/disable with no joy.
Some have said it's a carrier limitation, but it's not, cause in my iPhone, the very same simcard works just fine and the Internet is usable during a call.
Also tried with dual Simcard setup. As in the settings, the phone allows to use one simcard for data and one for call. Still not working.
Can someone please tell me if there is a solution please, or can you try your phone while on the call to see if Internet works as this feature is detrimental to me keeping the phone. If this doesn't work I will be selling the phone and getting a realme replacement.. Xiaomis sometimes suck with their non existent support.
Thanks

Global ROM 13.0.4
I can't see an operator fault if they have Volte services enabled and this simcard works flawlessly on other android systems.
As a matter of fact, any SimCard i have tried, so far 3 providers and the phone does the same thing. As soonest the call is made it downgrades the signal to H while full 5G or 4G is available??

the operator must provide the necessary information for each brand and phone to activate Volte and Wowifi.
On my 11t pro everything works with SFR and nothing with FREE because Free has not yet transmitted the information necessary to activate the services.

So went to see the operator. They sell Xiaomi phones. 3 network ( Three EU)
The phones in the stores are working just fine, no issues at all. And my phone simply just isnt.I have tried every possible setting and still not working.
See the screenshot below. As I'm typing this I'm on a super fast full signal 5G connection. As soon as I make a phone call, the phone will downgrade to E or H+ which is horrible. This network signal switching is also laggy, and If 2g signal is poor I cannot even make a call.

Does the "Use VoLTE" switch appear in the SIM card settings?
If not you can try the Dialer Code *#*#869434#*#*. That only will make this switch appear, but sometimes this is enough. It should also show the little VoLTE-Badge next to the signal strength (see screenshot).

I just had another look and on your 1st post it says the SIM is named "3 IRL", as far as I know Three Ireland does not offer VoLTE at all.
So it will always drop to 3G/H+ or 2G/E ... on every phone.

5G connection should support this naturally. If I put this simcard Into an iPhone or Galaxy the 5G connection stays on regardless.
Anyway even with Vodafone this doesn't work,so I'm thinking it either a phone limitation or a phone is fooked

No, for VoNR your phone still needs the same configs as with VoLTE. Though only a few operators support VoNR as of now.
