I am running Electrum (for Bitcoin wallet) along with Google Authenticator on a factory reset Android phone (which I no longer use as a phone). It's the only two apps I have installed on it and I put it in Airplane mode right after using it.
This seems to be a pretty safe way to have a cold wallet right? I'd think anyways.
I was wondering which is the best wallet for Litecoin on the Android, if there is one?
Coinomi is very good as it supports different pairs or crypto and Litecoin as well. You can also follow this link and find the information about the best wallets for alts and LTC-
