The transparent screen app has released for a long time, but some tablet users complain that it is not list in tablet's playstore, the reason is, there is a key feature to hide the app icon, and to open this app again, you need to dial a secret number. But for tablet, there is no dial app, and google did not show the apps since it has this feature.
So here is the version for tablet, the only difference with phone version is, tablet version can not hide the app, but do not worry, tablet still can set a password and fake a notepad app.
Notice this is a transparent camera app, it is using hack way, so the quality of the photo is not so fancy like other camera apps. But it is cool in another way. And the basic function like zoom in/out, it also can not support.
If it can not work in your phone, it just prove that android has so many different version, this hack way can not work in your phone. Just uninstall it. The positive/negative comments made me so crazy, because I can not do anything for you. And this also did not help anybody.
fix rotation issue.
