No noticeable change on new firmware. Same camera version. Only March patch from what I can see so far. I'm sure they've done other things but they're not telling us

I remember on my Galaxy S20FE that the Switzerland AUT ROMs were incredible. On the s23 Plus it's the EUX ROMs right (no more AUT)? If so, how is it doing, is it well optimized or you guys miss when it was local region only?

Little update about... The update... After doing a Geekbench 6 test, it seems the S23U achieved one of the most performant results since I got it.
Single core: 1970 (average: 1923)
Multi-core: 5216 (average: 5071)


The usual and generic "various optimizations" might have been true, on this one.

HI ALL

what is the best CSC to use - purchased direct from Ssamsung
I agree with @Jaxom84, just flashed the EUX ROM (and i don't even live in Europe) and everything work fine. 5G and LTE, Samsung Wallet... System seens fine, the same as the last patch on ZTO ROM (so no new lag), benchmark seens the same too.
But it's up to date and i have a feeling that as EUX ROM is made for first world countries with high expectations, it is well optimized, maybe even better then some for other markets.

The USA t mobile update just arrived and it does seem that the device went back to the fluid and smoothness even more so now the when i got it. Its flying to say the least and compared to my other devices that are a generstion older i can finally see the difference in animations very smooth!

    In this thread, you can discuss and share the Mega links of new firmwares (OFFICIAL STOCK) for the Galaxy S23 Ultra 5G!

    How to flash the firmware to your phone:

    Odin.png


    1. Extract (un-rar) the firmware file (i.e. to folder C:\Odin) ***
    2. Download Odin v3.14.4
    3. Extract the Odin ZIP file (i.e. to folder C:\Odin)
    4. Open Odin
    5. Power OFF your S23 Ultra 5G
    6. Reboot Phone in Download Mode: Connect USB-cable to your computer. Hold down "Volume up" and "Volume down" at same time. While holding down, connect the USB-cable to your phone. Or use the command "adb reboot-bootloader".
    7. Wait until you get a blue sign in Odin
    8. Add the firmware files to their designated slots (AP in AP, BL in BL, CP in CP, HOME_CSC in CSC). USERDATA stays EMPTY!
    10. Click the start button, sit back and wait few minutes for the device to automatically restart.
