Doesn't the sandboxed gplay services come with some usability or speed trade-offs?
Discussion
No. It's more performant, more compatible with apps, and more secure than microG.
The only real difference is that microG is built-in on Calyx, while Sandboxed Google Play Services need to be installed manually as Graphene doesn't include it out of the box.
Yes.
I've been using #grapheneOS with sandboxed google play services, everything runs smoothly,.
No performance issues, regular security updates.
