i am trying to get used at google messages!!send original photo without compression via google messages?
That's why we don't use sms at all. You can't send original pictures, voice memos and much much more. We all use only whatsapp or telegram here. With them you can do what you want.

did anyone else lost the ability to use google pay on their device ( SM-S908B/DS exynos, had changed last year CSC to SEK) after the update to S908BXXU4CWE1?

more info: seems that it has only a few CSC available now and I get the message that the device doesn't meet security requirements and in google store the play protect certification says device not certified

Delete Google play and Google play services apps data. Restart. If you are not rooted it should be certified again.
Cheers.
 
thanks, tried but sadly it still sees my s22 as not certified;
also the safetynet test fails on CTS profile match
Samsung miss to authorised their ...WE1 in Google Play Protect. (Happens many times with a lot of devices. First time on my Note20 I write and call Samsung... until any understood and answer me the next firmware comes.)

Options:
Wait Samsung to release next firmware ...WEx (x>1) or ...WFx

Downgrade via ODIN (AP, BL, CP, HOME_CSC) to ...WD3 (and turn of temporary OTA updates).

P. S.
Nothing other helps (delete, uninstall, even factory reset on this firmware), just firmware did not pass GPP. The chance Google to reauthiorize it is small than Samsung to push the next firmware.

It's part of firmware. They just can remove. Someone miss to do part of procedure. Happens many times on many phones.

I have experienced the exact same problem... I updated 1 week ago to the latest version and suddenly (yesterda) safetynet fails.

I have tried to downgrade via odin to the previous version and still experiencing the same problem (enabled hiding apps and installed sensitiveprops+safetynet-fix.

Did anyone managed to fix it with a downgrade?

DEVICE: samsung s21 fe (g990b)

Thanks a lot

My second phone S22U SEK CSC updated OTA to problematic WE1 and Play Protect said "Device is not cetified" in Google Play Store.

Because previous firware WD3 is still same bootloader "3", I just downgrade with ODIN (BL,AP,CP,HOME_CSC) and and status changed: "Deivice is certified" it is not needetd to install any "sensitiveprops" or "safetynet-fix". If device is with official firmware, no root, no knox tripped, no mods, Play Protect automatically verifies device and status become "certified".

* * *

For S23 series THL CSC updated OTA to WEA is is not possible to downgrade because bootlader of WEA become "2" and previous firmware WD1 have lower bootlaoder "1". So for S23 users have to want next newer firmware for certification fix.

    Hi! Is the same for s22 ultra? B version. Tnx
    S22 series B model - only SEK,
    other CSCs are in E model.

    ChoSmile,

    Since you seem to be very knowledgeable, would you mind answering a few questions for me?

    I am trying get some phones for our staff to record calls with. We are based in the US and use Verizon as our carrier. Most threads indicate that a CSC change is best, but from what I'm reading in your posts is that the USA models I can acquire and use domestically do not allow this?

    1. Will using Verizon and being in the USA pose any technical hurdles that would prevent a CSC change?
    CSC change is possible. Just any of the model SM-S91*B (Europe, Asia, Middle east, Australia), SM-S91*U and SM-S91*U1 (USA), SM-S91*W (Canada), SM-S91*0 (China, Hong Kong, Taiwan), SM-S91*N (South Korea) have different CSCs for the region.

    For U model available CSCs are: ATT,CCT,CHA,DSA,DSG,DSH,TMB,TMK,USC,VZW
    For U1 model available CSCs are: ACG,AIO,ATC,ATT,CCT,CHA,DSA,DSH,FKR,LRA,PCT,TFN,TMB,TMK,USC,VZW,XAA,XAG,XAR,LLA

    CSC change can switch ONLY BETWEEN model's CSC.
    Can notchange to EUX or SEK ot THL or any other CSC available for B model.
    Can NOT change MODEL U to B.

    NONE of these U or U1 model's CSC have Call Recording feature.
    2. Is the S22 S901u compatible with this method? If not, what in the S22/S23 family do you recommend that I can buy in the US through Verizon? Or what is a suitable modern android alternative you'd suggest?
    European users can use their B models (with their SIM cards) in USA. If there is an restriction(s)/allowance to use Verizon SIM in B model - as your operator (Virison).
    3. Will we lose OTA? If so, do I have to change the CSCs every month and change them back?
    No. Device will continue have OTA updates then new active CSC update is pushed. But this is again only between (1.) CSCs.
    3b. If I need to change CSCs to get an update, will the previously recorded calls get lost when the record option is hidden? Will I have to back the recordings up beforehand?
    No. Recording are not lost/hidden/deleted when CSC changed. But (1.)
    4. Orders from on top are no rooting or warranty voiding measures if possible, and I am technologically clueless enough that I just don't know what the best option here is.
    If rooted the recording call can be enabled on any CSC. But waranty void. I'm not sure if there is an working root metodfor U/U1 models.
    5. What about apps like ACR w/ the helper phone app, CubeACR, or Skvalex? Are those good options? Clarity of the recording is a high priority, if possible.

    Thank you for you time; I appreciate it.
    Recording with extarnal app do not have access to audio stream (after andorid 9), so both sides (your voice and your interlocutor voice) are recorded by you phone's microphone - this requires volume of the interlocutor to be enough high (up) to be captured by your phone's microphone and recorded with less lower volume (compared to your voice), ambient sounds (around you) also recorded.
    Just try them and deside by yourself.

    Bad news for people with S22 SM-S908B (Exynos) who used INS CSC (the one from E (snapdragon) model to have Call recorfing, anti-spam callerID and Samsung Pay.
    Until now we just make updates manually (BL, CP, AP, HOME_CSC) every month with any B FW (for example EUX) and were was up to date.

    BUT ....

    from version S908BXXU2AVH9 - Samsung removed the glitch ... so no more INS for B model ... CSC returns to EUX (or original CSC) and call recording, internal andti-spam callerID and Samsung Pay were gone.


    At the moment the ONLY working CSC with Call Recording is SEK (Ukraine).

    So with SEK (plus and minus):
    + Call recoeding works
    - no internal anti-spam callerID (Hiya as app can be used from playstore)
    - no SPay (the re is no working option at the meoment)
    + OTA firmware updates will work (via Setting menu).
    9
    For SM-S908E (SnapDragon):
    XID is SingleCSC and do not exist in MultiCSC, so can not be changed/switched by Samkey.
    The only option to change CSC to XID is flashing with ODIN. If flash with files: BL_, AP_, CP_ and HOME_CSC_ - it will not reset (with CSC_ instead of HOME_CSC_ phone will be factory reset)
    XID:
    - have call record,
    - do not have Samsung Pay (it have SPay but it is an Infonesian custom version with their local banks only, can not be changed with international SPay)
    - do not have internal spam, but can be used Hiya app (from PlayStore for any CSC)


    These CSC are from MultyCSC - all CSC are inside the firmware - and can be switched/chaged via Samkey at the moment (methods with local SIM, modded theme, Dialer code are fixed and not work long time ago, combination firmware works but no available files for current bootloaders)

    INS (India) have call record, SPay and and spam
    XXV (Vietnam) have call record, SPay, no int.spam but Hiya work
    THL have call record, spam, but SPay discontinued last year
    ILO have call record, other not sure (less updated, not every month, Jewish extra security)

    All CSC installs have specific bloatware apps (some can not be uninstalled but can be disabled via PC with adb or some package disabler via phpne)

    INS is better choice for E model.

    ---

    For SM-S908B (Exynos):
    Only SEK (Ukraine) via Samkey have Call recording, no SPay, no spam, but Hiya works

    ---

    For SM-S908 U, U1, W, N, 0 (SnapDragon):
    No know/available CSCs with call recording

    Using Samkey to chage CSC to one that not exist inside the exact same (U, U1, W, N, or 0) region of MultiCSC - do nothing, just lose one Samkey credit and CSC stays same.

    Flashing U, U1, W, N, 0 device via ODIN with E firmware is NOT possible because different models (even all are SnapDragon CPUs).
    9
    At the moment call recoring:
    S22 (SM-S901x), S22+ (SM-G906x) and S22 Ultra (SM-G908x)
    * is model 1, 6 or 8
    x is region (the region have several CSCs)

    SM-S90*B (europe) - Exynos - via Samkey (paid) to SEK, INS
    SM-S90*E (asia) - Snapdragon - via Samkey (paid) to XXV, THL, ILO (or via ODIN (free) flash to XID)
    SM-S90*U (us) - Snapdragon - no CSC with call recording
    SM-S90*U1 (us) - Snapdragon - no CSC with call recording
    SM-S90*W (canada) - Snapdragon - no CSC with call recording
    SM-S90*N (china) - Snapdragon - no CSC with call recording
    SM-S90*0 (korea) - Snapdragon - no CSC with call recording

    They write on the web that it is not supported, but it is not true. I risked it and it works! So S22u is my daily from today.

    1. Turn on the developer mod
    2. Enable usb debugging
    3. buy credit on samkey (on the web or ebay)
    4. Install SamKEY CodeReader
    5. connect the phone to the PC
    6. turn on samKEY, log in and change CSC.

    This operation didn't seem to reset my phone. But I can't guarantee it.


    screenshot of my CSC version:

    I would also like to recommend the "AutoSync" application, which automatically uploads all your recorded calls to Dropbox. It all works on the S22u.

    Thanks for your informative reply.

    So for me, my best option is to get Samkey credit and just do the simple Samkey procedure to change my CSC to INS (INDIA) ? Right?

    Do you or anyone know if INS (INDIA) CSC would caused any feature to be unusable? Like Google Pay? Samsung Health with Samsung Watch? And will INS CSC have bloatware apps? Like?

    And last noob question from me, does changing your phone CSC affect your phone BANDS / Frequency ?
    I am using INS (Not changed CSC but I am living in India)
    No carrier bloatware except one My Galaxy. All features like GPay,SPay,S Health,Spam Call, Call Recording are working fine
    My personal opinion about CSC changing
    1.For Non Rooted device - Go with SamKey
    2.For rooted users - Instead of changing CSC just modify your own CSC file and get desired features. OR use a ROM with preactivated features
