I have been using a personal wallet on my smartphone for a long time and the wallets I use are trustwallet and bluewallet. If you want your smartphone to be safe from all hack vulnerabilities, never click on a site carelessly and don't carelessly install applications outside of the Google Play Store.

Don't forget to regularly check your smartphone with an antivirus because viruses that attack smartphones will usually always be updated, also save your password and personal wallet key phrase in a safe storage that only you know, as long as you are careful and careful, your wallet will be safe.
