Avoid repeated COME APK downloads after Back
Inspect Downloads and the app list before pressing the original button again.
Work through this situation
Back can dismiss a page or installer without removing a saved package. When the previous action is unclear, use the browser record and Android app entry as separate checkpoints. A fresh page load does not answer either question.
What to check and why
Determine what the Back action dismissed. Leaving a webpage differs from leaving the Android installer; either can leave a previously saved file intact. Check Downloads for completion and Android's app list for installation. Those records are more useful than trying to reconstruct the process from the page currently on screen.
If the file is complete and the app was not installed, open the existing identified package. If the app is present, open it and compare its version when updating. If neither result exists, return to the source and begin the missing stage. This sequence prevents a navigation action from becoming a reason to accumulate several identical files.
Keep acquisition and installation separate
The COME button on this website opens the external app page. Saving a package, installing it through Android and opening an account are later steps with their own results. Use the browser record for transfer questions and the Android message for installer questions. A repeated visit to the first page does not automatically repeat or repair every later stage.
What a completed answer looks like
You know whether to open an existing file, read an installer message or open the installed app.
Continue from the stage you have actually confirmed. Preserve the exact message when a step remains unresolved.
