The case has a sticker inside for the fingerprint. After removing the protective sticker, you should not touch it because the sticker gets dirty and the fingerprint will not work afterwards, as happened to me, plus the dirty glass is constantly visible. Also, it is a bit heavy and bulky compared to other cases and it does not have a good grip, in short, it slips like a fish. Furthermore, I have the impression that the temperature of the phone had increased significantly when it was in the case and as soon as I changed it, it straightened out.
