OS9 Lock Screen Customer Insights

1. The only reason I didn't give it 5 stars is because some apps or functions will still show up when it is locked i.e. when a FB chat bubble pops up.Really like this screen! It seems work good so far! Really wish I could replie to notifications but I cant figure it out! But I can see them! I dont like always having to use a 6 digit password But just started using so I give up date after using for awhile.This app is very good I've been using it for a few days and it works 100% of the time I've used a different lock screen app before sometimes it would work a few times but then it stopped working but this app works 100% of the time.

2. So far I love this app and planning on keeping it.I've gave five stars to OS9 Lock Screen because I'm currently on a Samsung tablet and it's really easy to just unlock it so this app has helped me with getting a password and even everything else it can do I'm sure can help other people on their device.
