How do you know if your tamagotchi connection dies? I think mine are dead, it looks like there is a UFO and I can only look at the information, does that mean it’s dead?
You should check the device's page on the wiki,u should find how the death screen looks like,also for resetting in any case that happened,press Left (A) + Right (C) at the same time.
Yeah,your tama died,if you are only able to look at final stats,means you neglected it or it died.
