Alan, was there a specific version you're talking about? You can get ARC on google play, that's been around for awhile It's not on the Apple app store yet though - but will be very soon.

Yes it will work on v4.1.2 for sure. Other members have used/are using the same OS version, and slightly older as well (I beleive v4.0.4 worked as well). Something that might be worth a try, and that's installing the latest Android OS your device can use, if your device allows it.

Thanks for the play link. I searched for it before answering and didn't see it.

Search for EZ-Robot doesn't find it. Search for ARC does. Most apps will show up if you search for thw publisher.

Alan

it also say iff your device is compatible

Taken from Google play...

Requires Android 4.0.3 and up

So the version your running is deffo not the issue.

@traxx, dumb suggestion, but have you restarted your Android decice lately? I hace occasionally seen a signature error on installs or updates if I haven't rebooted in a while.

Hummm, very strange... Yes I've restarted my device many time.

It.s seem to be compatible:
