Is the COME installation prompt from Android or a web page?
A webpage can display text that resembles an installation instruction. Check whether the message belongs to the browser page or Android's system installer.
Read the surrounding interface
Look for the browser address area, app controls and the action that triggered the message. Page content can include pictures of buttons or settings. An image of an Android dialog is not the device's actual permission screen.
Use the normal handoff
Start from the completed APK in a recognised browser or file manager. Android then presents its own installation checks. Do not grant elevated access or install a helper because a webpage claims it is mandatory.
Keep warnings meaningful
If the actual browser or Android protection warns about the file, stop and read the guidance. A website's reassuring text does not override the device message. Keep the exact wording for a legitimate help request.
A useful next step
Proceed only after identifying the interface that owns the prompt.
