My results on Google Nexus 7 2013 (4G) - deb
1. Can you receive coins? (small amounts to avoid losing them)
Yes

2. Can you send coins?
Yes

Its says it's still waiting because I was still syncing the blockchain
3. Can you scan a QR code from another phone or Paper Wallet (to send coins).
Yep. send the dev and the guy who posed above me .05 QRK.
4. Can you request coins via email or other android service?
Havent tested
5. How long does it take to sync the blockchain?
Took about 30 minutes. Needs a lite version if possible, or the ability to turn off syncing on data!
6. Does it drain out your battery after an hour?
Went from 100% to 88% in exactly one hour. Androind reports that the wallet app took half of that

7. How much space does it take up on your phone?
Android reports 51MB

8. Does it calculate exchange rates properly?
Reports $0.0701 for USD. Sounds about right.
Needs the ability to add nodes!
There are only 2 in the app, and one is always +/- 100 blocks apart.
Sending and receiving is deathly slow compared to how fast quark is.
