Just tried my game on an LG G3 and it glitches a lot until eventually the networking gets dropped entirely, whether it's hosting or joining another device as a client. I've also had issues with a Shield Tablet, although I think its networking is busted anyhow. I only send a packet or two every tenth of a second, so it's not like there's a lot to deal with.
Has anyone else had much experience of particular devices being problematic? Is it a rare thing and are there any fixes?
