No October security patch for my S7 Edge SM-G935FD in Singapore, still stuck with August 1 patch. No Samsung Cloud and new gallery in my S7 edge where reported on tech website and sammobile said its included.
Singapore CSC of XSP, i think will wait for ages for October patch, i don't even dare to think about Android 7.0 update for South East Asia Countries, Samsung is slow in rolling oit software updates and new features with inconsistency.
I use galaxy s7 930FD in Vietnam and i got update October security update week ago. I got Samsung cloud from last month update. Did you root your device? Try to check update from about or use samsung link or kies.
