COMEAndroid says App not installed for COME
Keep the exact message and compare the completed file, device requirements and existing installation before retrying.
Work through this situation
That short message can have more than one cause. It does not prove a signing mismatch, lack of storage or a damaged package by itself. Change one understood condition at a time and preserve the working app.
What to check and why
Write down the complete installer message and when it appeared. Then verify the package completed downloading, the receiving device matches stated requirements and sufficient storage is available. If COME is already installed, record that version too. These are observations to gather; they are not proof of a specific cause.
Change only an understood condition and check the resulting message again. Repeating the same file many times produces little new information. A conflict with an existing application, a damaged file and a compatibility issue require different remedies. Do not uninstall a working app or disable protection merely to see whether the generic message disappears.
Identify the exact device stage
A completed browser download says that a file was saved. Android separately decides whether it can install the package, and the app separately handles its first loading and account access. Keep Play Protect active and read the full device message. A working installation is worth preserving while you investigate a different release or an unexplained error.
What a completed answer looks like
A specific cause or source guidance replaces repeated attempts with the same unexplained failure.
Continue from the stage you have actually confirmed. Preserve the exact message when a step remains unresolved.
