Doesn't read my finger – Harry Potter: Spells - Free Review

The game seems like a very fun idea but it doesn't read my finger at all it didn't work for me at all and I loose in battles all the time because of it all i think it needs is a little update I already checked I'm doing the spells correctly and my finger obviously works on my phone.
