There’s also Zwallet - which can sync the entire ZECpages wallet on a Nokia Android CrapPhone ™ in just 2 minutes 58 seconds (all 2400 txns & 1600 notes).
It also supports viewkeys, multiple accounts, auto-shielding, displays notes, history, lots of features.
We’ve been testing it here :- Zwallet & Ywallet Testing (RELEASED!)
You can install from PlayStore here :- https://play.google.com/store/apps/details?id=me.hanh.zwallet
You can get code to build it from here :- GitHub - hhanh00/zwallet: Zcash and Ycash light shielded wallet
I’m not the developer, I’m just a volunteer helping to test it.
If you have an Android phone please try it & post your feedback. Its insanely fast, has a nice UI & worth your time to check it out.
EDIT: Updated sync time for Version 1.0.8-2059
