Installation pages should do more than say download and tap install. They should tell users what the phone will ask for and what the first screen should look like.

The install step is only half the job. The first launch tells you whether the app, wallet, and help route behave the way the page promised.
On Teen Patti Badshah, the safer order is: finish the APK download, confirm the install permission request, open the app, then inspect the first Teen Patti and card-table checks area and the wallet view before you do anything else.
If the landing screen, wallet wording, or help route feels different from what you expected, stop there and verify the page again.
Move into the bonus and payment pages once the app is installed correctly.
