Mobile crypto wallets are not safe from virus & malware perspective. Largest antivirus companies work with only Windows OS antivirus, antimalware software versions, but not mobile OS. So therefore it is very wise to move to desktop crypto wallets. Otherwise - one day you wake up and your crypto mobile wallet balance is 0 due to received virus/malware. Even if some antivirus company made soft for mobile too, it is not also safe due to lack of experience.
