I was searching for the best Ethereum wallets around and below are my findings.
The best rated seems to be Exodus, however it is only available for desktop not for Android. I use my phone for everything these days so had to pass.
Coinbase also offers a wallet, though it is centralized. I signed up but could not enter my card details for some reason, so coild not purchase anything. This might be a good option for purchases if I can make it work.
Finally I downloaded the Jaxx app from Google Play. You can opt to create a wallet for Ethereum, Bitcoin and some other Alt Coins. The app is just a wallet not an exchange but I was able to successfully swap some existing Bitcoin for Ethereum successfully in a few minutes.
So far I am impressed with Jaxx as an Ethereum wallet solution.
