Exodus
Bitcoin wallet is good. If you use with Trezor, you get the nice design of Exodus with the security of hardware (no private key leak)
If you would have bothered to at least halfway read the OP and to check what wallet he is talking about, you would have noticed that he is specifically asking for a mobile wallet.
@OP:
You didn't mention which OS you are using and what kind of cryptos you want to store on your mobile device.
There are quite a lot of good BTC wallets available for android. But only a few for ios.
The two BTC wallets for android i like the most are
mycelium and
samourai.
Both are open source, have a nice interface and work flawlessly.
If you are privacy-orientated, you might want to take a look at samourai. It has some nice features built in.
