I probably should not have said *everything work* without qualifications like this.

Most apps work. Some may require sandboxed play services.

This was also my experience. Most will work, a few may not out of the box and you have ways of making them work

ok. And if I don't know how to do this, I'm assuming I'll be able to figure out it.

Sandboxing = putting some apps into their own walled area so that they can't tap into the other data on the phone?

Thank you!
