Eversolos apps

Hi if one removes 1 of the internal apps in the A6 are they lost if so how to get them back?

 

Why should one do this?

Some Apps can be sideloaded as I read. But I don`t think the pre installed eversolo apps will be found in playstore or so to reinstall...

Btw: A factory reset should solve this problem?

 

I am not sure you even can remove the stock apps that came with the device, only side loaded apps.
