The only app that can backup App data is Swift Backup but you have to have root access. Titanium is no longer supported.
you may also try Alpha Backup Pro. for full functionality you have to grant root access.
Titanium still works fine for app data backup.
Any news of this? Keen to consider this ROM if GPay working? What about "OK Google"?
Yes. Without Gapps (or microg), you can't have notifications on apps that rely on GCM (Google Cloud Messaging).
All kernels are good ... the most important thing is the ramdisk optimizations !
