where an Android install file comes from and the one field to check first
The same exchange app pulled from an official download page and from a third-party site often shows a different signer and package name. Compare both before you install.
Check the package name and signer against the official download page first, and skip the install if they differ.
Key points
Package name
On the pre-install app info screen, find the package name in the com.xxx.xxx form and compare it letter by letter with the one listed on the official page.
Signer
The installer shows a signing fingerprint or developer name; if it does not match what the official site publishes, the file was rebuilt.
Permission list
Expand the permissions before installing. Contacts or SMS access on a trading app is a stop sign.
Source domain
The address bar on the download page must match the official domain exactly; one extra letter or hyphen means a different site.
Common questions
What if the official download page does not list a package name?
Use the developer name on the app store detail page as the reference, and hold off installing until both sides agree.
I already installed it and the package name is wrong. Can I still use it?
Uninstall it, then download again from the official entry point, and never type your recovery phrase or codes into that app.
