[Q] Amber brown bad network issues need your help...

Dear xda users,
Hello everybody,i am new here an would appreciate your help.
I bought an Samsung gt-i9305 (color:Amber brown) before a month an half ago,The Rom that com with it is from Vodafone U.K.
From the beginning I experienced with it some pretty bad network issues,there could be full or half bars but the problem is that from time to time I cannot make or receive calls/text messages nor use my data connection,the signal and the net bar are seems like everything are o.k seemingly?
I use it on 3.5G without Lte and set the setting to WCDMA/GSM ,also search for my deafult carrier provider,even after 2 updates of android os and still nothing.
The problem could happen 3 hours from i power it on or during the day in randomly way(most of the times in the evening ).
The only thing that can fix it,is restart to device or if i search provide manually.
Now,i am afraid there a problem with the device and i have warranty but don't want to go to the store i bought it from,because i know they are no rush to replace devices and afraid they will open the device hardware for nothing (for the record it is not bought from Vodafone).
This brand new phone and this thing disappointment me very much,by the way there is any kind of way to connect somehow to the modem and test it,maybe by app?
If anyone has experienced this before with the amber brown model and resolved it themselves that would be great to hear, I would love to get this fixed.
Thanks in advance to everyone,
David

"Flying mode"
Dear banjomike,
Thank you for your replay but the problem is when it happen i could do nothing with the phone is like is in "flying mode"
It is a problem with the modem? rom?
Can some one please help me on this?
Thanks...

Nobody???

Have you thought about contacting the seller ?
They may be able to offer a repair / replacement.

Dear Raistlin1158,
Trust me the store that i bought from even this multi-branches network, have no rush to replace anything,they will test maybe open it and still maybe say that all of it,is just from the rom,that what i want to thing anyway.
Still you might ask why i bought from them,cause in my country only they are sell this model.

Have you changed the rom on your phone ?
Where are you based ?

No,i did not change the rom,yet.
Since you asked,i want to change,this is one of my last option before contact the store.
The funny thing is i thought my rom is vodafone u.k,now according to sammobile i have an germany vodafone rom,it could be even if the deafult keyboard was samsung u.k?
My rom PDA is : I9305XXBLL5
i want to change it to: I9305XXBMA3 Nordic countries it is o.k?
my network work on wcdma: 850/2100, this network based on company called pelephone.

Signal is driven by the modem, you need to match the CSC to the area you live in and as you have avoided the question twice I can't help you,
Have you checked to see if the phone been blocked by your provider ?

First i would like to say thank you for trying to help me.
O.k but the problem is that from time to time I cannot make or receive calls/text messages nor use my data connection.
I do not have signal problem or no entery sign.
The phone is brand new and my provider did not blocked him because the problem is randomly.
How i can match the csc to my area? by what paremeter to 850/2100.
Sorry i make you feel that I avoided ,i am not, I live in Israel and using "pelephone" network.
Thanks again :good:

Hi,
I leave in France and updated my GT-I9305 with I9305XXBLL5 (DBT - Germany - unbrand) and have no carrier problem..
Anyway, the nordic ROMs XXBMA3 have the same modem "XXBLL5".. (GSM 1800, GSM 1900, GSM 850, GSM 900, LTE 1800, LTE 2600, LTE 800, UMTS 1900, UMTS 2100, UMTS 850, UMTS 900)
What do you have on your screen when enter *#1234# on dialer?

Download and use this, it's the top one I9305XXBMA3 labled HTD:
http://samsung-updates.com/region/?region=HTD
Do it through Odin.. 3.04 is the most stable version.
Then you should be fine
Sholem Aleikhem

I am having similar problems on that firmware when I have my phone on CDMA/GSM mode
What helps with me is to switch to LTE/CDMA/GSM mode.

Pelephone
The network started as AMPS/NAMPS in the 800/850 MHz band. In the mid-to-late 1990s it converted to IS-95 CDMA and later added CDMA2000/EV-DO capabilities as well. A UMTS network in the 850/2100 MHz bands was launched in early 2009, and serves the majority of the network's devices.
APN settings
APN: internet.pelephone.net.il
Username: [email protected]
Password: pcl
for enabling MMS - add these :
Server: pelephone
MMSC: http://mmsu.pelephone.net.il
MMS proxy: 10.170.9.54
MMS port: 9093
APN type: internet + mms

Not the same LTE frequency as GT-I9305
Only works on GSM 850 and UMTS 850/2100

First,thank you all guys from the bottom of my heart!
Dear Raistlin1158,
I must to mention that i like very much the Sholem Aleikhem
I entered to the site that you posted and i noticed that is from the network 3.
I have trust in you and if you say that it will work with 850/2100 bands i will install it but it not like Vodafone,that come with a lot of junk? again i do not understand it like you.
Now,before flashing with Odin i understand i need to "clean" my device,if i will clean it from setting it enough or i will need to wipe data and cache in download mode?
If any time in the future i will need (i hope not) the warranty and need this exact Rom i install the same and that's it?
Thanks m8
Dear kanzi83,
Thanks for the research,i also triple check the setting on my device.
When i dial *#1234# i get this screen:
AP:I9305XXBLL5
CP:I9305XXBLL5
CSC: I9305VD2BLL2
Dear prosperot,
Do you have an work lte on your area?,because in the beginning i also had Lte/Wcdma/Gsm and had some problem.
Have a great night/day everybody

This has the same CSC as you have now (German Vodafone ) if you need to return it to original, again the top post:

The best way for a clean flash is to wipe before and after flashing.
Before (to clean the data and cache)
After (to clean the bloatware of first operator's ROMs)
2 way for Wipe Data
wipe data (from Recovery Mode [vol up + home + power] Not Download Mode)
No need wipe cache / do wipe data only (erase data and cache)
option to do wipe Dalvik cache
*2767*3855# from the dialer (don't test it if you don't want to reset - This reset your phone when enter the last # )
n'joy

Dear kanzi83 and Raistlin1158,
Thanks a lot i will flash my device in the next couple of days.
By the way i need to activate debugging mode from setting,right?

Huawei Mate S 4g+ issue

I recent buy a Mate S, I'm the first owner. My issue with it is that it wont go on 4g+, it appears only 4g in the right top corner of the screen. I had already changed two operators, first time I was on Vodafone 4g+, and now I'm on Orange 4g+., I taught the mobile operator was the problem but...
I've called the operators, and they told me the problem is not from them because they already have my phone settings in their data base and should had worked.
When I get the nano sim out, and put it for example in a S6 Edge, or S5 Neo, 4g+ connection is avaible, but when i get it back in my Mate S, it wont work.
I've checked already the access name points: Name, Apn, Proxy, Port, Server, MCC, MNC, and they are all the same, like the other phones.
I turned on the 4g+ function from the phone internet menu, the phone restarted automaticaly and nothing hapens, just 4g.
My country is Romania, from Europe and i have the curent firmware CRR-L09C432B361,EMUI 4.0.1, android 6.0
My frustration is that I pay for 4g+ speed, and my phone is brand new. The seller wont change the phone because it has pass 31 days from the buing time.
I've sent it in service, but the only thing they done was an update, stock firmware and new update with the same problem...
Please help me with and advice, i am very greatefull, have a nice day and please excuse my gramatical problems, i don't excelate in english.
This is my first post, please be gentle.

No worry, if i'm not getting any answer soon, i'll call them at TelVerde România: 0800400896. Somehow, i'll find an answer. The phone is ok, but I would like to use the 4G+ connectivity too. I'll write here when i'il have an issue.

Where is the option to select 4g+ in the settings? I have B361.

Settings -> The first "More" -> Mobile Network -> The last option "Frequency aggregation" (that must be "on").
Huawei answered me. They told that the Huawei Mate S has 4G+ capabilities, that it can aggregate romanian frequencies carriers (for example, band 3 and band 20 for Vodafone Romania which means the 1800 MHz and 800 MHz bands aggregation). But the speed is limited because the phone is LTE Cat 4 only.
And the most important, the 4G+ icon is a standard protocol of the phone and it is possible to see 4G icon instead 4G+ icon even then the frequencies aggregation is realized. In romanian: pictograma de 4G+ reprezinta un protocol standard al smartphone-ului, de aceea este posibil ca in dreptul liniilor de semnal sa va apara specificat tot conexiune 4G, desi smartphone-ul este conectat la 4G+ prin agregarea benzilor.
The last part seems a little strange to me: I have a 4G+ connection, but the phone shows only a 4G icon and the speed is max 150 Mbps because LTE Cat 4 capabilities. For me that is like the phone is a 4G phone only with a menu option that makes you believe you have a 4G+ phone.
I think that I'll go to the service center too.

Strange switchs 4G (LTE) to H+

Hi,
I'm new in MI8 community ? (just living leeco lepro3 ). I've strange switchs between 4G to H+.
I explain ?. Previously, at home, I was all the time in 4G with my PRO3. But now, my MI8 switchs time to time and during the switch I loss the connection. Nevertheless, my device receives full signal in 4G and it stays connected on the same BTS.
If I set it in plane mode ON and after OFF...back to 4G for a short time...
I'm on miui10 and on Sosh (orange) french network.
Tks for your help

Hey !
I'm also french and i'm experiencing that kind of H+ switches, as you I had 4g in these areas before with my oneplus 3 with Bouygues Telecom ISP and now i can't even connect to the internet, must be the antennas...

I can connect to 4G but something doesn't work fine...I can't stay connected. The level of the signal increase and dicrease strangly.
I'm a little bit disapointed :crying:

Because each phone have different bands and if your phone doesn't have the right band for your area cell tower then it'll keep changing back to the most stable connection it can do.

Sure, I know that. But I leave in campaigne with only one BTS. So I'm always connected to the same antenna.
And if it was an issue with the frequency band (lepro3 has the same), switching OFF/ON, airplane mode should not fix my issue.
I've tested with Mate 20, and i'm always 4G in full power received !

Nobody else has the same issue ??

I have the same issue, 4g and H+ are switching all the time. Sometimes it keeps switching several times in a minute on a fixed location.
I am in Croatia, operator is A1, Mi8 Global model.

very well it seems like it's not an isolated bug. can we trace this kind of problem to xiaomi and if so by which channel?

Hi, i'm still facing time to time the issue. No fix planned? I'm not alone.

Zero promises here but you can try forcing the network mode to LTE/UMTS auto (PRL) and check if it makes a difference.
To Change 2G to 3G 4G LTE only network mode in Android Phone via USSD code, take the following steps:
Dial *#*#4636#*#* OR ##626* OR ##786# in your phone
Select Phone Information
If you have Dual SIM Select the Slot (SIM) you want change settings for
Scroll Down and select the Option Under “Set preferred network type”
Click to expand...
Click to collapse
Also works by pressing 5 x times on settings \ my device \ total storage

Thks but It's not a good solution. I won't force network type choice.

If you flash 9.1.17 Xiaomi.EU they have updated Network Switching handover to European UMTS, instead of default chinese TD-CMDA to WCDMA as Stoffl_ says.
I had the same problem as you say of switching from LTE to H+ because of this. Either change it manually after boot or unlock the bootloader and flash another rom. Until they fix it in global, if they do.

You have use it and fix the problem?

Just ****ing change the network mode ffs

So, after few month my feedback. I've try to force the switching of prefered type of network and it does not work. So I expected a new version of MIUI who can fix it...
Today, I'm in the lastest Miui 10.3.3.0 stable and the issue still

"VoLTE provisioned" is off - Mi 9T Pro

Hi team,
This is a Global Mi 9T Pro, Miui 10.3.2, bootloader is not unlocked.
LTE 4G works, however no "voice over" - it reverts to 3G for voice calls.
*#*#86583#*#* results in "the number you have called is not connected", using both SIM 1 and SIM 2, have tried 2 different SIMs that show "VoLTE" on Reno Oppo Z and GS8. 4G switcher app shows "VoLTE not provisioned". Any suggestions on how to enable VoLTE? I have tried a factory reset once...
Thanks
(I can't add links - it's on imgur slash YFFWVNu )

I'm in Brazil carrier Tim, unfortunately there's no specific MBNLoader file for this carrier, so I selected the generic Brazil MBNLoader, it wasn't enough to turn ON VolTE in calls though, it reverts back to 3G or 2G
any other ideas?
PS found a post on another forum that says the Malaysian MBNLoader will be fully compatible with the carrier TIM on Brazil. I tried it and it worked perfectly, now I have VolTE. GG

If you are "roaming", does it switch by it self to proper MBNLoader? (if my question make any sense?)

I think what you're asking is if the MBNLoader changes automatically depending on geolocation or when a new SIM card is inserted. TBH I don't know. But if I would have to guess I'm guessing it is a setting that you select when turn on the device for the first time, and that remains selected even if you insert a new SIM card. Lemme know if i've misinterpreted your question.

Question 5G not enabled by default

Hi there,
I apologize in advance if the question has already been answered. I searched but found nothing.
And I apologize for my English, I'm French Canadian.
I bought a OnePlus 10 Pro 12gb/256gb, model NE2213 last week.
Everything works fine except for 5G. I only have 4G (LTE) by default but with the 5G settings app I can select the NR option to enable 5G. Everything works fine and I can use 5G without any problems.
When I restart my cell, I again come across the 2G/3G/4G option only, no 5G.
The option seems to be there and functional but it does not seem to be activated by default.
Is there a solution for this?
Thanks a lot !!

Besides your APN there's not a huge amount you can do.
Is your phone an actual NE2213 or has it been converted?
If it's the latter then that could explain things..

Thanks for your answer!
This is an original NE2213 model purchased from a Canadian website. It was 30% cheaper than the North American model and I read on the internet that the bands were compatible with 5G.
It's not the end of the world because 5G is not really deployed here in Canada but I don't understand why I can activate it via the 5G settings app but when the device restarts it seems to be desactivate.

Oh ok, crazy, an EU device being sold from a Canadian resupplied does shout region change to me and would explain things..
Are you based in the EU?

No, I live in Canada and I'm on the Bell Mobility network which uses the n66 and n78 bands for 5G.
This website sells different cell phone models less available in Canada (OnePlus, Xiaomi, etc.) but sells Chinese or international versions.
Like I say I can live with it, 4G is as fast as 5G here for now, but I was wondering if there is a solution to enable 5G directly on boot.
Fun fact, when I set up the cell for the first time, it was showing 5G in the top right but when I was done with my setup and turned off the wi-fi it was rendering 4G and i can't choose 5G in the network options.

Just out of curiosity, what's your expected speeds on 5G and what are you getting on 4G..I don't use 5G on purpose. I simply don't need it as 4G gives my 250Mb +
Anyone who needs more then that needs a PC

I did a live test...
5G: 69/3 Mbps (d/u)
4G: 56/5 Mbps (d/u)
I'm at home and wifi is off.
Basicallyt, not a big difference, I'm going out today and redo a test to see if the speed is really different.

Do another test outside of my home...
4g : 61/24 Mbps
5g : 141/44 Mbps.
Big difference this time!
