I ordered the white pack one as it seems to only have a small cut out around the speaker, the two pack ones looked more open around there. I guess I’ll find out in a few days when it comes if it’s good or not.
Yes, only one opening for the speaker. See post #9 in this thread. No problem what so ever with Face ID, and I never had to retrain it after glass installation. Still registering my face at 100% accuracy.
