Electrum, Atomic Wallet, and Exodus. These three phone wallets are among the best options for me. They are characterized by a simple interface and great security. They are better than the wallets of the exchange platforms. I advise you to use them on your own phone away from your personal phone and do not download any cracked applications or from unknown sources on the phone that contains the wallets. I have used these wallets for almost several years and have never had any problems, You just have to keep the private keys and seed phrases in a safe place.
