That’s really strange, sorry about that. It sounds like a compatibility issue with your specific device, which is obviously pretty hard to diagnose from here. If it means you can’t use the meter I understand and am happy to offer a refund, let me know over email (firstname.lastname@example.org) and we can arrange it. Or if you want to hold out for an update to your tablet, that’s great too :)
Regarding your icon: Now that I see it as “ET looking down a well” I cannot unsee it.
