m8 android box help

Well what have you actually tried, like installing them from Play Store, or sideloading the APKs from another source, and what actually happens, like what errors are you seeing?

I've got a T95 Android box myself, and I use Kodi on it installed from Google Play.

 

I agree with what @mikedt posted, there's a lot of missing information and necessary details to make any kind of relevant suggestions.
If you're relying on apps from the Play Store, did you successfully enter your Google account info in the Settings menu. if you're Google account isn't authenticated, you can't install apps from the Play Store.
If you're installing apps via APKs however, without knowing just what the error messages are it's hard to determine what the problem is.

Offhand, buying something like a set top box off of Ebay 'could' be a problem. If new, not so much but if pre-owned than you're buying something that has an increased potential for weird issues, like not being able to readily install apps.
