I rate Symantec Endpoint Protection Mobile a nine out of ten for stability.

The solution is stable and reliable. That said, when I first put it on, I did have an issue with the VPN, which conflicted with the built-in VPN version on my phone. 

I never experienced any downtime with Symantec Endpoint Protection Mobile. It's fairly stable, and it does its job nicely. For the longest time, I didn't see any issues with the solution at all other than it getting angry at other applications.

There is no issue with the stability of Endpoint.

The stability of the solution is good. I'd rate it eight or nine out of ten.

The solution is stable.
