Still nothing on EUX, i think that samsung have now blocked OTA when you change CSC as my fold 4 has had no OTA for last 3 months with a change to CSC, even smart switch doesn't work, i've had to flash the last 3 SW updates with Odin

@jimmyk87 

What is your current, "Service provider software version"?

[jimmyk87]

I bought it used, I have changed the CSC to EUX when i first bought it as it was originally a 3 network device, since then its had no OTA, hence why its now BTE, as i've tried just about every UK CSC without success

@jimmyk87 

Yeah, your phone is now a, "Heinz", (57 varieties). You will never get an OTA with that configuration. The Active CSC code is BTE = stock, unbranded, U.K., Samsung. No October update so far for BTE or H3G (Three network), for which there is no Fold4 CSC code. 

[jimmyk87]

I have cycled through EUX, EUY, EVR, BTB and BTE, none give OTA unfortunately

@jimmyk87 

There I must stop as discussions about changing your CSC code are, quite rightly, frowned upon in these forums. Perhaps ask on a forum devoted to your issue.

Off topic I am afraid.

This thread, as per the title, is dedicated to the launch of the Fold4 October update.

However, from looking at your screenshot of the issue it could be a number of things causing that spot. Here are some diagnostic procedures you can run to see if the issue persists...

Restart your device

Open dial pad and enter... *#0*# and a diagnostic screen will open. Test Red, Green and Blue screens. Does the mark still show on those screens?

If so, try wiping your cache partition and repairing apps as shown here... https://eu.community.samsung.com/t5/galaxy-z-fold-z-flip/wipe-cache-partition-repair-apps-amp-galaxy...

If after doing the above the mark is still there, try running your device in Safe Mode as per the video...

If the mark still appears you may have a dead pixel and need to contact your nearest local Samsung Service Centre for them to look at it.
