Yeah, not sure why but I don't need them to run 4g concurrently anyway since I'm only using the 4g data on 1 sim.

If both SIM are always inside then u can select which SIM u want to run 4G from the SIM Manager..don't need to swap SIM tray

Mine also did not prompt to restart when i switch network in SIM manager..unless if i switch SIM card on the tray.

UAG case works well on clear coat? i am currently having clearcoat with samsung slim case. planning to get the UAG case.

LoL..imagine after key in 30 digit pins to unlock the phone and see a "OK" reply from your chat 

I'm sure that owner gonna be so proud of the highly secure phone.

Am using face & fp unlock combo at the moments and it works like charm. If one day my phone kena snatch that fella would still need to make me stay still to take a photo of my face and a close up on my iris in order to unlock my phone to use my samsung pay account 

On a side note, who else is rocking an alcantara casing on the s8/s8+? I'm in love with that casing thou it does not offer robust protection but the comfortable feeling you felt from it is just awesome!
