Unfortunately I will give you only 4 stars. Overall the app is great, even with the free version it's highly customizable. It works great. The only flaw I noticed is: when the AOD turns off, the actuall block screen comes to live out of nowhere and it's not aestethic at all. It would be great if you could manage to turn off the screen in the same time.
But again, overall this app is great, and it's the only one that worked (for me) on Huawei p40 lite. Thanks for the app, and please fix that important detail so I can give the 5 stars.
