The COME APK size changed: what should you check?
A changed file size deserves a source and version check. Size alone cannot tell you whether a file is a legitimate update, incomplete or unrelated.
Compare like with like
A listing size may be rounded, while a browser shows transferred bytes or a saved-file size. Ensure you are comparing the same kind of value and the same release. A decimal-format difference is not automatically a content difference.
Inspect the current file
Read the offered version and source again. Check the browser's completed status. A substantially unexpected size or a different file type is a reason to pause rather than rename the file or assume a faster download is better.
Avoid overclaiming
Matching the old size would not prove safety either. Keep Android protection active and follow its warnings. When seeking help, report both values, their sources and the exact transfer state without asserting a cause that you have not established.
A useful next step
Continue only after the offered file and the comparison you are making are clear.
