Yeah, why not? In fact, our mobile phones are more safer than desktop since malware can't be easily drown, IMO, as long as you don't use public wifi then you're safe.
The guy above is saying that mobile phone are as risky as using a pc because it can also connect to the internet but i also agree on what you have stated . mobile phones are more safer because they cant be attack by a virus .
Meanwhile , we can still off our internet data or mobile data so that there is no potential risk that we face when we connect our hardware wallet to our mobile phone .
Using a public wifi is safe as long as you activate your vpn . so that no one can trace you . there were also other apps to protect you from any risk when using public wifi .
then mobile crypto wallet isnt really belong to that category but would rather acts as a hot wallet than cold ones.
You can still lose your bitcoins or crypto due to various reason, like clipboard virus or something similar. Sure you might be protected to some degree but if you're not careful enough hardware wallet is still not enough to protect you.
Samsung or other phones is a waste of money imo, better stick with Ledger.
