Why is there no popup window for oppo SMS?

You can set whether a specific application displays a floating window. According to the system version of your mobile phone, please enter the specific path to turn it on or off:

Version 1, ColorOS 12 and above: "Settings > Application > Floating Window", which sets whether the specific application displays the floating window.

2. coloros11.0-1.3 version: "settings > application management > floating window management", to set whether a specific application displays a floating window.

3. version 7.0-7.2 of coloros: "settings > application management > floating window management" or "settings > security > floating window management" to set whether a specific application displays a floating window.

Tips:

① Pop-up advertisements may appear after opening the floating window.

② An application can only open one floating window at the same time, and the mobile phone desktop can only open one floating window at the same time.

③ System doppelganger does not support application doppelganger.
