COMECOME APK transfer while the phone screen was locked
After unlocking the phone, check the browser's transfer state. Screen locking does not tell you whether a download continued, paused or failed.
Read the current status
Device and browser behaviour can vary with settings and network conditions. Open Downloads and inspect the intended item rather than assuming background work completed. Read any message about connection, power or storage.
Avoid broad setting changes
Do not disable every battery or security control because one transfer paused. Use the browser's normal resume or retry option where appropriate and check the actual condition it reports.
Verify before opening
A partially saved item should not be used as an installer. Wait for completion and compare the source and file details. If repeated interruptions occur, record the device, browser and exact status for help.
A useful next step
Move to Android installation only after confirming that the file finished.
