Currently, I am using Lighting Bitcoin Wallet which is available at the Google Play.

I've already tested with success:

1. Onchain transactions.

2. Opening channels.

3. Sending funds.

4. Receiving funds

5. Restoring the wallet on a new mobile.

I'm impressed, how well the different functions of the wallet were documented by his creator Anton Kumaigorodskiy on its website.
