So do my phone needs to download the blockchain?
You don't have to download the blockchain on your android device. Synchronizing your android client with the Lightcoin blockchain is another step that is being tested.
Ok, because I wanted to test it and tried out the faucet but didn't receive anything on my android wallet.. Maybe faucet didn't payout.
Some people complained about the faucet not paying out. I will contact the faucet operator and investigate this issue! Meanwhile I am going to organize another giveaway so people get to know our new android wallet and test it.
