My battery life has gone to absolute piss since the update. I can barely get through a working day now and end up throwing it on the charger as soon as I get home from work.
I have the same problem (s9+ snapdragon). Try uninstall updates for Device Health Services app from Google Android do not update It from play store. I did this yesterday and my battery life improves a lot. Sot and sleeping.

I did the Geekbench test right after the Antutu one, so that might be why the score is a bit lower compared to previous tests. But, average is about right.

certainly cpu score was decrease.

I confuse, which one bettter ? android 8 ? android 9? my aim is much much much performance ! which one better performance ?

android 8 cpu 93000
android 9 cpu 88000


8 gpu 94000
9 gpu 107000


8 ux 56000
9 ux 53000

8 ram 8900
9 ram 8500

After CSD1 update I'm having Wi-Fi issues; if I don't use the phone for a while (5 minutes) when I wake up the phone the Wi-Fi is stopped and I have to enable it again from the quick drawer or settings. Didn't change any settings after the update, I have no idea what is causing this.

What's that app for anyway?

I disabled it, too. See if things improve...

Edit: that app doesn't show up in the Apps list anymore. It's not even under "Disabled". :confused:

I just tried to flash with odin 3 v3.13 and I get : "sw rev. check fail (bootloader) device: 3, binary: 2" on the phone screen. Odin just stays forever at system with no progres.
After a forced restart the phone is ok, I just can't use this fw to update.

Edit :
Downloaded odin again from the first post here (same version number) and it started flashing now; strange, I used the same odin until now with no issues :)

What firmware were you on and which were you trying to flash?

The error you posted is from downgrade protection when you try to flash an older bootloader than what is currently installed.

I was on csd1 and flashing csd4; it worked, I'm on csd4 now, however I still have the wifi issue.
Now that I think back it is possible that I was flashing the older pie version that was still on my pc (by error)....

Hi everyone ! I updated my G965F Exynos to last April security patch ota G965FXXS3CSD2 (Pie), and I want to revert to G965FXXS2BRK3 (Oreo) . From what I've read and heard I can't downgrade because of new bootloader,is this true?
I'm very frustrated and disappointed right now if is true, I'm thinking to sell this phone, because I can't choose what I want to use.
Is there any other ways to downgrade safely?
Thank you!

    Its crazy to update, it gives the sellers of phones a chance to fxck up your phones, samsung even got planned obsolence on bicycle batteries, 500 charges and the battery gets suprisingly bad so you will have to buy a new one.

    I accidently updated my galaxy s9+ and immediatly the battery got bad.

    The long threads on every phone site on problems with updates should be a big clue for you.

    My galaxy note got super slow after a update so stop updating if you want your dear phone to last.

    Latest stable firmware:

    G965FXXUGFUG4 / G965FOXMGFUG4 / G965FXXUGFUG4

    ---------------------------------------------------------------------------------

    How to flash the stock Odin flashable firmware:

    1) Download Odin v3.13.1 - Link

    2) Extract the firmware file you just downloaded. You should get 5 files:
    • AP (System & Recovery)
    • BL (Bootloader)
    • CP (Modem / Radio)
    • CSC_OXM (OXM CSC file, will wipe your phone)
    • HOME_CSC_OXM (OXM CSC file, will NOT wipe your phone)

    3) Add each file to it's respective field in Odin v3.13.1. Use CSC_OXM if you want to do a clean flash and HOME_CSC OXM if you want to keep your apps and data.

    4) Reboot your phone in Download / Odin mode with the following button combo:
    POWER + VOLUME DOWN + BIXBY

    5) Once in download mode, connect your phone to the PC, preferably using the original USB cable you got with your phone. Odin should detect your device and a blue box will show up with the COM port number.

    6) Do NOT tick any extra boxes. The only options to be ticked are F.Reset Time and Auto-Reboot.

    7) Click the start button, wait for Odin to say 'PASS'. Once the flash is complete, your phone will reboot.

    Firmware screenshots, changelog, and download links will be in 2nd post of this thread.

    FAQs:

    1) Will this trip KNOX, and will I lose my warranty?
    Answer: Short answer would be no, your KNOX counter will remain at 0x0 and warranty stays valid as well.
    However, some service centers might note regional differences between builds based on the latest build available for your CSC, indicating that the phone has been flashed, so if you're sending your device in for a service/repair/replacement, then I'd suggest flashing to the latest build available for your home country's CSC. Usually not required though, so not a big deal.

    ---------------------------------------------------------------------------------------------------

    2) What if the firmware build number mentioned above is not available for my CSC, can I still flash it?
    Answer: Yes, if your current CSC is part of the OXM multi-CSC. You can check that using the Google Doc I made here:
    https://drive.google.com/open?id=1IQglKMUCJXfs5UIeSehd1d6s5a6Rh_fC1WuPdycxotY

    ---------------------------------------------------------------------------------------------------

    3) I flashed 'XXXX' build, but now I can't get OTAs for a newer build that's available on my CSC?
    Answer: Now, I'll be using fake build numbers in this example, but you should still understand how I'm explaining this.

    Suppose your current build is very old, XXU1ARA1, and the latest available multi-CSC OXM build is XXU1BRA1, so you flash it on your device.
    Now, BRA1 is not released for your specific CSC, so you won't get OTAs for it to any further builds because no subsequent OTA file exists on the Samsung server for your CSC.
    Samsung will then release a new build for your CSC called XXU1BRA2, so the only OTA file existing on the server for your CSC is XXU1ARA1 > XXU1BRA2, so an OTA from XXU1BRA1 > XXU1BRA2 will not be possible, and the only way to regain the ability to get OTAs, is by flashing BRA2 and then accepting further OTAs from there on.
    This may seem cumbersome to some people, but if you're impatient and always want the latest build, then just continue flashing as you normally would.

    ---------------------------------------------------------------------------------------------------

    4) Can I flash the ROM in the main post without flashing the builds that came before it?
    Answer: Yes you can. When flashing ROMs with Odin, you don't need to be on a specific build to flash them. They don't need to be flashed in order.

    You can be on the oldest possible build and flash directly to the latest one.


    Important:
    ---------------------------------------------------------------------------------
    The files linked in this thread are ONLY compatible with the following devices:
    SM-G965F (International Single SIM)
    SM-G965F/DS (International Dual-SIM)

    There are no Dual SIM specific ROMs, any ROMs for the G965F will work on the Dual SIM models and you will retain Dual SIM functionality and both your IMEIs.

    You can download this using SamFirm or Frija

    Country: Germany (DBT)
    Version: Android 10 (OneUI 2.5)

    UPDATE:

    Stable Pie (XXU2CRLI) is now available via OTA and SamFirm for G960 and G965F users.
    I will be uploading to AFH and MEGA, but for those who can't wait, go and attack Samsung servers and get it through SamFirm.

    Sadly, I won't be able to experience it for a few days since I'm giving my S9+ in for a battery replacement today, but should get it back later this week.

    Merry Christmas and a Happy New Year to everyone! Don't forget to thank Samsung for getting this update out to us early :)

    August update - G965FXXU6CSGD

    Comes with new kernel, new baseband version and August security patch.
    Official changelog also mentions improved camera performance which could be regarding the issues with Night Mode crashing that were introduced in the CSF2 update.

    For those wondering why the update still has CSGx build number, it's because the build/compilation date was still July and not August like some other devices.
    Like all other OEMs, Samsung gets access to security patch details well before they're released to the public so the build dates don't always have to be in the same month that the patch is intended for.

    CSC change tutorial for 965F

    Thanks to @applepay and his CSC change method in the S9+ forums, I have tested the guide and posted it with screenshots.
    It works 100% as described by the OP, CSC is changed on my device and proof has been given below.

    You can use this tutorial to switch to your desired CSC for getting quicker OTAs. However, keep in mind, if you change to a CSC that is different from your home country, you will no longer be able to use VoLTE, WiFi calling and Samsung Pay. Furthermore, doing a factory reset with a SIM card from your home country will revert back to your previous CSC.

    This will NOT allow you to register for the beta program.

    I would also like if anyone with a region locked device, such as BTU/BTU/BTU could test this tutorial to see if it changes the CSC for them.



    Let's start off by saying, I did NOT find this method, I simply used the guide from @applepay in his thread HERE.

    I've added screenshots and proof to show that this works, and to show you how to use RealTerm to change the CSC on your device.
    Now, the main purpose of this would be to help those who have region locked devices, however since I don't have one, I can't test this. This will also benefit those who want DBT for example, for quick OTA updates, but don't have a German SIM card to change the CSC using the normal method.

    My device is a local Pakistani model so the CSC was PAK/PAK,PAK/PAK. Just for proof, I tried changing it to NEE (Nordic Countries). Screenshots are given below.

    ---------------------------------------
    Step 1) Power off your device and make sure to back up all data, since this will require a factory reset. REMOVE your SIM card before proceeding further.

    Step 2) Boot into download mode, and flash the combination file for your device. I had a v2 combination file for S9+ already, so I flashed that.
    Download link for v2 combination file for G965F - AndroidFileHost
    Your device should look like this while booting:

    https://imgbox.com/v7ajO7iW

    Step 3) Fire up RealTerm and connect your phone to your PC. Once booted into the combination file, it will say either SM-G965F or SM-G965F [DS] if it's a dual SIM device.
    Should look like this:

    https://imgbox.com/9ZdRS0BJ


    Step 4) Click the 'Port Tab' on RealTerm, for me it showed Port 8 = \ssudmdm0000, if this shows up for you, it means your device has been detected by RealTerm, then set the Baud rate to 230400
    Screenshot:
    https://imgbox.com/OpwRG4qD

    Step 5) Go to the 'Send' Tab on RealTerm, enter 'AT' and hit the 'Send ASCII' button, you'll get this as a reply:

    Code:
    USB READY
    BOOTING COMPLETE
    AT

    Screenshot:
    https://imgbox.com/1ky52t8k

    Step 6) Enter 'AT+PRECONFG=1,0' and hit 'Send ASCII' again, you should get your current CSC as a response, in my case it is PAK.
    Screenshot:
    https://imgbox.com/iZgiAkqg

    Step 7) To change your CSC to your desired CSC, use this command 'AT+PRECONFG=2,???', replace ??? with the CSC you want to install on your device. I chose NEE, so my command looked like this: AT+PRECONFG=2,NEE
    Screenshot:
    https://imgbox.com/yTAo0uGI

    Step 8) To confirm your changes have been applied, type this command to test the current CSC, 'AT+PRECONFG=1,0', your response will look like the message in the screenshot below:
    Screenshot:
    https://imgbox.com/u2LjnmZU

    Step 9) Go to SamFirm, type SM-G965F and download the latest firmware of the new CSC which you have applied. Flash in Odin with AP, BL, CP and CSC_OXM and your device will reboot. Since the CSC has been changed, first boot will take a little longer than usual.

    Here is my device with NEE CSC instead of PAK:
