Why can't I dinstall recent apk's on my coolpad 3632a it says Android version 7.1,
it downloads them but when i try to install them it wont let me press the button
It's not greyed out, it's the same color as the cancel button and I can press that one?

Welcome to Android Central! So if you press Install, does anything happen at all? It may still be a screen overlay issue, even if the button isn't greyed out: https://www.howtogeek.com/271519/how-to-fix-the-screen-overlay-detected-error-on-android/
