Xperia C4 Dual E5333 - deactivate SIM function not working - Android 6 bug?

[Arnoldinho]

I have an upgraded Xperia C4 Dual E5333 (Andoid 6.0) with 2 SIM cards (upgrade done with Xperia Companion)
SIM1: GSM only  - used for PHONE
SIM2: LTE/ (preferred)/WCDMA/GSM   - used for internet


To decrease the battery usage, I want to Disable the SIM2 card when I don't need the Internet access.
used the "Settings -> SIM Cards", and wanted to disable the SIM2, but I got: "Error, can't disable all the SIMs." - I don't know why this option is not working as my SIM1 is absolutely active.


I read the related book here, but no solution.
http://support.sonymobile.com/global-en/xperiac4dual/supportDocumentation/

I disabled Mobile Data, and tried many many combination in "Settings -> Data Usage - Mobile Networks", but the "disable SIM" function is still not working AT ALL --- AT ALL, as I have tested it wth SIM1, and also got the same "false" error.
There is ONE BUTTON solution to acivate/deactivate SIM2 to decrease the battery usage of it - I want to avoid any mobile signal when the SIM2 is disabled, this should be done by the menu in "Settings -> SIM Cards", but not working, and I think, this is a bug.

Hello

After the upgrade, many strange things happened:
Sometimes, I lost my ringtone setup... 😞
Sometimes, some other settings were lost!
etc.etc...


What I have done - in brief:
Switch off "My Xperia function" - REQUIRED!!!!
Created new backups into Google Grive, with the Xperia Copmanion, and into my SD card - JUST TO BE SURE
SOWFTWARE RESINSTALLATION with Xperia Companion!!!!!!!!


Tested the SIM deactivation - WORKING WELL!!!!!!!!!
Resored from my BACKUP files from Google Drive - BAD IDEA, some strange things happen...
Decided to do factory reset via the Android menu (same/similar like here:   https://support.google.com/android-one/answer/6088915?hl=en )


I setup everything one by one again...
Now everything works fine...


new feature arrived: if I tpye a phone number, both SIM card call function is available
like this:

NEWS !!!!

Bad - Worse - Worst 😞

Fist of all - BEFORE THE REPAIR: the SIM1 signal was always full, and the SIM2 signal was about on halp - I had no problme with it, but got the message "Mobile Datas is disable" - don't udernstand why I got is many many times a day when the mobile data is disabled (SIM2 used  mobile data).

NOW 😞 - AFTER THE REPAIR

both SIM1 and SIM2 signal lost many many times... how can this happen?

Yesaterday, a the newest upgrade appeared, so installed, hope Sony realised some thing... but no, still lost every SIM signal... tried many many variety, tried to change the "Preferred netwrk type" from LTE(preferred)/WCDMA/GSM" to "WCDMA(preferred)/GSM" - NO SUCCESS

Tried many thing, change SIM cards, used only one SIM card, etc. etc.  after some time, the signal went out...

Other Phone has full signal with both SIM card - all bills are paid, etc. etc - so please don'T ask this kind of basic question

This is at least Sowftware, but maybe

One thing - I have a new 4G SIM, but not able to choose the Vodefone 4G network - only the 3G??? Tried also with or without SIM1/SIM2 - so many variety.

Why? This phone knows the LTE.... what is the problem with my Phone now?

HELP!!!!!!!!!! not able to call, as the breaks!!!!!!!!!

ONE MORE THING - I HAVE NO FULL SINGAL AT ALL - NO FULLY SIGNAL!!!!!!!!!!!!! only half or LESS!!!!

I will try the last software repair with this new latest Android - if no solution, then go to the service to try to repair my pohne...

Hope Sony not only a brand name but quality - please help!!! I likke this phone... and I paid for it!!! need a usable Phone what promised when I bougth this

Now I know why the "Mobile data is disabled" message repeatedly many times a day (without any manual action before them).... because the SIM2 signal lost many times in the background, and the when it got the signal again, then it refreshed this settings and give the message...

so the "Mobile data is disabled" recurrence it not a bug... it works as expected...

but what about your phone... sorry... my Phone, as I have paid for it
The C4 is buggy? Or the Software? Or both?
As I wrote, before the SW repair, I had full signal on SIM1 - only SIM2 had half signal as per the screen shows...

I am very sad, as the mobile signal is a basic function in a phone... without any compromise...

Please ask! Thank you in advance

New software available - downloadad, upgraded, still got the signal problem

Using only ONE SIM card, the other one is in my old phone (with always full signal at the same provider)

I have tried many many variations with the SIM1 and SIM2 cards and with the options but got the same reult.

I have spoken with some "service personnel", who told me, that the Sony software has bug... I agree with them.

Dear Sony upport, this is a fastidious topic, but if you mend your product (software or hardware), that is a new trust again for your brand.

Do you have any service Application to share with me to find the problem? Do not hesitate to give me the access, I am on to solve the problem, I get liket my phone till the Software repair (because of the SIM card deactivation problem).

I will do another software repair without any data restore... let's see what will happen...

Hi Can somebody help me please..... I upgraded my Sony Xperia C4 Dual last week via xperia Companion but since then i have had alot of issues with the phone.

1. Touch screen hangs

2. It registers mobile network and loses it after some hours

3.It does not boot into Recovery mode with key combinations.

4. No PC detention through USB cable it only charges even after selecting MTP mode from Developer options. I have done a thousand factory resets but nothing seems to get me any where. Please help.

Hello

I had the same problem, and after the upgrade to 6.0, the E5333 becames unusable (day by day worst, and some days later, not able to call at all...). Tried everything, contacted the Hungarien suport, etc. etc.

The reason what Sony forget to implement to the "xperia Companion", that the NON-EU versions doesn't suport the Android 6.0 upgrade, and if you implement it, the phone became unusable.... (this is waht the Hungarian Service said to me).

After this, I bought a phone from a different company...
