When Three get around to certifying their carrier branded firmware so that Samsung can release it. For fast firmware updates, always get the stock, non carrier branded, phones.

Just recieved update on h3g just so you can update list.

Cheers! Also, O2 has released their firmware.

Have amended post #3.

One feature of this release that I personally find redundant, is RAM Plus...

Settings > Battery and device care > Memory > RAM Plus

I have 16GB of dedicated LPDDR5 RAM built-in which I very rarely use more than 10GB-12GB. However, there is no option to turn off the RAM Plus feature completely. No big deals as I have set it to 2GB.
