COMEAndroid Says App Not Installed for COME
An “App not installed” message means the Android package step did not complete. Keep the full wording and review the file, device and existing-app context before changing anything.
Confirm the package was fully saved
Check the browser download status and compare the source and offered release. An incomplete or unexpected file should be resolved at the download stage. Do not rename the extension or open several copies to force a different result.
Inspect the relevant device conditions
Review storage and the current package’s requirements. If COME is already installed, note that version and preserve it. Android can refuse an update for package or signing reasons, so an existing app should not be removed simply to bypass the refusal.
Treat protection warnings separately
If the message identifies harmful software, follow Android’s protection guidance and stop. A generic installation failure and a harmful-app warning are different conditions. Keep Play Protect enabled and ask the service about the exact issue when the cause remains unclear.
A useful next step
Use the Download page for the current entry and ordered checks. Continue only after the file identity and Android message are understood.
