Oh, I forgot to add that. Yes, it has 64-bit processor with 32-bit OS. So I replaced the OS. You can check your processor's architecture using AIDA64 app from play store.
• Is it possible to hide weapon outside combat? -No, only if you unequip them.
• Do passive one hand sword abilities work for dual blade? -Sorry i dont use ohs ><
• How to cancel attack animation (to dodge aoe)? -You can't (as far as I know)
• How can I inspect/view other people? It seems there are locked icons -I think the lock icons are for functions that aren't in the game yet
• Where is best place to get info/guides on this game (builds etc.)? I know coryn club is great database. -I like to use the app Amino, here is the link to the Toram amino: http://aminoapps.com/invite/QXU6Z497FG
Check if just your OS is outdated or if your device is running on 32-Bit SoC.
Go to i.e. Settings > System > About phone to check the OS version, and Settings > System > Software updates to see if there's any update available. There may be also an App named Update or similar in your App drawer.
Or you can use DevCheck to get the information easily.
Depending on manufacturer and model, there's still a small chance to get a official system upgrade, i.e. Android 6 > 7 or 8+, but it makes only sense for a 64-Bit device.
Check
If it's 64-Bit but there's no update available, you could try to find a inofficial update or alternative ROM for your device (*requires probably Root access and unlocked Boot Loader definitively). It'll require some technical knowledge though.
Toram Online Official App is not supported by the Wireless controllers. If you like to play it with controller, you can use Octopus App from the Google Play store https://play.google.com/store/apps/details?id=com.chaozhuo.gameassistant&hl=en , and Mapped your controls there.
P.S. I haven't done it, Cuz it was classified as tweaking the game itself. So you might get banned. Do it at your own risk.
