COMEA small COME APK listing and later app data
The listed APK size describes the download record. It does not necessarily describe the app's installed footprint or all traffic during later use.
Separate storage measures
A saved installer, installed program, cached content and account-related data can occupy different amounts of space. Android's app-storage view and a browser's file size answer different questions. Compare like with like.
Expect current information
Use the size shown with the actual offered file. Do not assume that a smaller transfer guarantees faster operation, broader compatibility or less future data use. Those conclusions require different evidence.
Use the device's feedback
If Android reports insufficient storage or the app later needs connectivity, address that specific condition. Repeated downloads will not explain an installed-data difference. Avoid clearing app data without understanding the effect on local access.
A useful next step
Check available device storage and current file details before installation.
