If I have choose, I will use ledger hardware wallet for mobile phone because more secure than software. you can read https://www.ledger.com/ledger-goes-mobile-ledger-live-app-now-available-for-ios-and-android-smartphones can be use via bluetooth for ledger Nano X and use USB OTG for ledger Nano S.
That is also a better choice to have ultimate security for our funds and there is no barrier to access our funds anywhere we can use our mobile, connecting viw bluetooth looks new for me definitely I have to buy a one for me.@OP as others saying coinomi and trust wallet are best ever app to store multiple cryptos in your smartphone but it is nit recommended though because our smartphones are easy to hack with simple clipboard trojans via installing an application from random source.
