What operating system do you have now. Are you happy with it? Yes, stay with it. No, switch to the other one

I would also give priority of importance to the server you have contracted. The mobile is for making calls and accessing the Internet. Both are handled by .... your server

I can't say much, because I get the iPhones used by my brother, so I can't complain, the same with my server. But I recognise that the Android system (on my Tablet) is a marvel when it comes to file management, data transparency, access to the OS, etc. I use it a lot

(To take pictures I use a machine from .... to take photos)
